Sewing Pause: Trousers for Jim.

This is an open thread. The following is an explanation of what I’m up to.

——- ——– ——- ——–

My 92 year old mother-in-law is currently in assisted living. We noticed she needed new clothes. When I shopped for clothing replacements I rediscovered what I always new: Finding suitable clothes for a 4’10”, 100 lb woman is not easy. I did manage to find “size 6 petite, proportioned short” elastic waist pull on trousers at JC Penney’s , but I still had to take 2″ off the hem.

After some discussion with Jim we decided I should just make her similar slacks. Well, mostly I did. Because I know that in the end, making slacks from scratch will save time. (Or so I thought.)

I bought a pattern, shortened the crotch and legs to take out 8″ of excess length and made a pair of trousers out of light weight stretch denim. (Total cost for materials ~$15.) They came out beautifully. Now that I have an adjusted pattern, I figure in future I can make her 2 pair of slacks in parallel; the task will take about 3 hours total. (I find adjusting the pattern takes more time than anything else. This is true even if adjustments are simple. Likely things will go faster as I get more efficient.) That’s less time than driving to JC Penney, hunting through the rack to find slacks in “not totally icky colors” (e.g. of a totally icky color is magenta or line green), finding a top that matches the likely not-icky- but possibly unusual color , bringing them home, and hemming the slacks.

I patted myself on the back for saving time. I can now make Rosemary slacks while I’m waiting for the clothes to tumble dry or doing other tasks.

But the… Jim said “These are nice. You know, I could use slacks too. . . ” As the 5’8″ 120 lb man living in a country full of overweight guys, Jim also has trouble finding slacks. I have generally thought it worth spending the time shopping because men’s slacks have more “fiddly bits” to deal with. But as American’s get fatter, and/or specialty stores get bought up by big conglomerates, Jim’s shopping problem actually seems to be getting worse rather than better. As long as I am on a sewing binge, I dug into my “stash” of fabric, found some nice olive drab corduroy. Jim approved of this fabric.

I also found an old never used Mens pants pattern printed in waist sizes 26″, 30″ and 34″. As a fair number of sewers know, both off the rack clothes and patterns for women are somewhat “vanity sized”. (The problem is worse for off-the-rack clothes with the result that off the rack sizes often don’t match pattern sizes at all.) No matter what the pattern says you sort of have to guess a bit about size. (The companies have gotten better about printing exact dimensions on the tissue– but still…) But I wasn’t sure to what extent men’s patterns or off-the-rack clothes might be “vanity sized”.

Anyway, Jim reported he has gotten “porky”, and now thinks his 28″ waist pants are “tight”. So, under the assumption the ‘vanity size’ issue does not affect men’s clothes to the extent it affects women’s, I interpolated and traced the size 29″ waist size onto tissue paper, shortened the length 2″, cut the fabric and began assembling. I sewed in the zipper (a very fiddly bit), the crotch and inner thighs then loosely basted the outer legs. Because I haven’t been sewing much in two years and I’d never sewed in a traditional men’s fly, the processed involved a bit of cursing. (I did some stupid-not following the directions bit. My old 4-H teacher would have shaken her head at me. Naturally, I resorted to the cure she taught me– I used the seam ripper a lot. )

Here’s how they look (complete with chalk marks):
JimPantsAndMoSmall

Jim tried them on for fit this morning. They fit nicely! Who hoo!!

After trying them on Jim said “I’m trying to decided if these should be cuffed or no cuffs.” I explained to him these would not be cuffed providing an illustration of the “geometry problem” associated tapered legs which makes adding cuffs something one will wish to pre-plan. He now knows that if he wants cuffed he needs to warn me in advance.

Today, I’m going to pick apart the basted side seams, add the side pockets, waist band and so forth. I’ll hem in tomorrow evening while we watch tv. Then, Jim will have new pair of pants.

But… of course, the entire “this will save time” issue was an illusion. Jim seems rather delighted with the notion that I will make him slacks. He hates shopping– and really the ordeal always ends up taking a huge amount of time. Here is 100% approved reason to excuse myself from watching Monday Night football with the Jim and Sunday Football with Jim and his brothers:
FabricForMorePants

Now…I’m going to go upstairs and and get those pants to the point where I only need to hem them tomorrow night.

  1. Hi Lucia,
    One of the innovations at our place is the shirt pocket added to the otherwise pocketless knit T-shirt. Growing up, and living in a family of engineers, even though I fell into architecture, has imbued me with severe reluctance not to have a 3×5 notepad and Uniball, (in earlier years, a Rapidograph) with me at all times. The notepad is to accumulate notes, have paper with me to show someone “what I mean.” Stuff like that.

    Jan’s solution is that “we” buy the T-shirts she thinks i ought to have and then she sews pockets on them. The best are black shirts with pockets made of very colorful floral cloth. For some reason, no one ever comments on these, but I love them.

    Frank Lloyd Wright once revealed that he had his mistakes painted red, everyone would think they were intentional – maybe a similar idea.

    My solution to finding pants that fit at K-Mart was to lose 20 lbs. This is the same 20 lbs an earlier spouse had recommended I lose to save all the money I would have spent on converting from tube to solid state electronics on a plane we owned at the time – ostensibly to increase usable load.

    SteveF. Re: marine autopilots, Writing the code and doing the electronics for a micro-controller (Arduino Mega2560, for example) rigged to manage a 12 volt servo is not nearly the challenge you suggested, maybe because there’s a lot of code out there, known to work, which can be deciphered, understood, and then adopted, if you don’t want to take the time to roll your own.

    It does tend to make it easier if you work with a GPS signal, because as DeWitt said, you get a continuous reference to bounce your heading-hold off of if you are not going to run routes. I should point out that this is my next project, I haven’t done it yet, but three friends have, two sailboats and one trawler. And they all work. One of the sailboats just completed a circumnavigation with his.

    is that O/T enough?

  2. J. Ferguson–

    My solution to finding pants that fit at K-Mart was to lose 20 lbs.

    That won’t work for Jim. Do you remember that Jim Sr. was slim? He ate like a horse. And what’s more Jim Sr’s side of the family was the “husky” side. Jim’s mother’s side are tiny both in height and frame. Many 5’8″ could weight 140 and be perfectly healthy– but Jim would actually be pudgy at that weight. If you think of the difference in build between John Wayne and Jimmy Stewart, Jim has a more “Jimmy Stewart” frame– but not as tall. So it’s just hard to find him slacks– and shirts etc.

    I don’t think Jim could gain 20 lbs if he tried. But if he did, I doubt it would be healthy.

    His brother’s are 5’10” and weigh roughly 150 – 170. (Robert is the ‘slim’ twin; David is the ‘fat’ twin.) They are built more like their Dad and can find clothes.

    (Some people will always suggest trying kids clothes. But that doesn’t work because the kids are shorter and have narrower shoulders.)

  3. I have a 30 waist and 28 inside leg; almost no one makes trousers that fit me, jeans not a problem, but am not allowed to wear them at work.
    Sometimes I think I should just eat more junk food and buy 32/30’s.

  4. Doc–
    Jim is thinner than you are. He can also find jeans– though sometimes that means mail order. His most recent jeans are 29″ waist. When we married he wore 27″ waist jeans! You can imagine that if you have troubles, he has even more!

  5. Lucia, I did not think I would be able to add much to a sewing thread, but your post did bring back memories of my mother’s sewing and not to save time but because our family was rather poor and frugal during my early childhood.

    I grew up on a Midwestern farm and we received chicken feed in some very colorful bags that my mother would sew into shirts for my brother and me to wear to school. I liked the patterns and I probably did not care or know any better that those patterns must have rung out “I am wearing a chicken feed bag”. They did itch a bit because I would think they were not condition for wearing. I was never attacked by a chicken though. My mother’s sewing machine was electrically powered and it had a knee device to activate the machine so she had both hands free to guide the material. She would purchase patterns that appeared to be made from tissue paper and she would cut out the cloth with the patterns as a guiding overlay.

    How do they do it today? Do they have computer programs to direct the machine in cutting and sewing the material?

    Growing up on a farm we had 4H, but in those days it was relegated to rural and farm kids. Later I think kids in the city had 4H clubs. Lucia, I had you pegged as a city girl.

  6. Kenneth–
    Machines generally either have a knee or foot pedal to advance the needle. Mine has a foot pedal.

    Patterns are still available on tracing paper. They come in envelopes with instructions. The pricing methods are odd. For example: On Friday, I will go to the store and Simplicity brand patterns at $1/ each. The claimed theoretical prices is something like $10-$14 each depending on the pattern. But I know there will be at least 4 $1 a piece sale dates. So, I’ll go in and buy some other men’s shirt, pants etc. patterns.

    You can also now download pdfs and tape them together. These generally cost about the same as the theoretical prices of patterns. And they are a bit of a PITA to take all the paper together. (It would be different if each was a program and you could adjust before printing out– but I don’t think you can. Though I might be wrong.)

    You can also buy pattern drafting software and create your own patterns and print those out as pdfs. If you sew infrequently, the pattern drafting software is a bit pricey and 10 years ago– generally about $200 or so. (And back then, the would seel the “mens” and “womans” programs separately!!)

    You can adjust to get custom fit in the program though. My impression was that the number of patterns remains limited relative to what you can get on at the brick and mortar stores though this wouldn’t be much of an issue if all you want is men’s slacks. Also, I had a friend who was very heavy and she loved one of the programs. When women are heavy, they tend to be heavy in all sorts of different ways. (Bottom heavy vs. top heavy vs. apple shaped and so on.) This means that custom adjustments are nearly always required, and owing to the three dimensionality issues involved, the adjustments can be a PITA. So, she loved the software.

    (In contrast while slender women’s shapes differ, they don’t differ in ways that make pattern adjusting hell.)

    I have never made anything out of old chicken feed bags. That said, I think it is possible to buy jute or hemp fabric these days. It tends to be pricey and aimed at the “greener than though” crowds. I suspect it might be similar to the chicken feed bags, though possibly the threads are spun to a finer diameter and the material ends up less rough.

    I did 4-H from 6th through 8th grade which, btw, is also available in cities. I did: Sewing, cooking, crochet, macrame, and mosaic. I might have done something else, but if so, I don’t recall. I would never have learned to sew well without 4-H. My mother doesn’t sew very much. (Nor does she crochet. She does cook. I didn’t continue trying macrame or mosaic.)

  7. My mother used to make many of here dresses, using paper patterns and her electric sowing machine. She was a little lady, with a large bosom, and couldn’t get dresses to match her age. Like me, she could get things that fit from the teen’s section.
    There are huge numbers of dress patterns available, ebays lists 47,000. If you are a little lady and don’t want to dress like a teenager, its not a bad way to go.

  8. j furgeson,
    Sorry about the warm beer the other day.
    ” if you don’t want to take the time to roll your own”
    I was thinking in terms of ‘rolling my own’, so the programming would be non-trivial. If there is some existing code available, that could make it easier. But in any case, the mechanical hardware (reliable half-horse DC servomotor and controller, plus hydraulic pump and valves) is going to set you back over $1,000, so all your efforts are not going to save a whole bunch of money compared to just buying a system.

  9. Woa… Lucia is BOTH a queen of sewing and knitting, AND a brutally honest wizardess statistician. 🙂

  10. Re: SteveF (Jan 9 19:10),

    I’ve collected links to DIY UAV flight control programs and supplies if you’re interested. Dedicated data loggers for competition cars start at ~$1,000 and go up rapidly from there depending on the bells and whistles.

  11. Hey, SteveF were are talking sewing here.

    Lucia, yeah that’s the ticket. My brother and I were “greener than thou”. I’ll have to remind him when I see him next. He’ll get a laugh out of that.

    My sisters lived on the farm and had 4H but were definitely city girls at heart. My brother and I not so much (our father made sure of that) – until we got to high school and college.

  12. SteveF,
    I have chain steering and already have the motor, so my out of pocket cost is likely to be less than $200 depending on what I have to pay for the gyro and accelerometers and whether I buy another GPS chip. I guess I should have mentioned that new system is to replace existing orphaned system with intent to having accessible code to see if I can get the “wow” out of the steering in a following sea that’s very annoying in the present system.

    I should also add that I’m not all that sharp with this stuff, but am not starting from scratch, am very persistent, and expect to spend a year to 18 months getting it right.

    The warm beer was just fine as was meeting you.

  13. Eli/SteveF
    I’ve seen Jules stitching stuff before. She is a fine seamstress indeed. I’m sure better than I am. But my Jim is a more conservative dresser than her James! My Jim would wear these:

    http://julesstitches.blogspot.jp/2012/12/j-jeans.html

    But not these:
    http://julesstitches.blogspot.jp/

    On the other hand, my Jim will wear wild shirts on weekends in the summer. But he prefers more subdued trousers.

    I on the other hand would wear all sorts of stuff from pretty wild to fairly conservative. It would all depend on the situation.

  14. Kenneth–

    Lucia, yeah that’s the ticket. My brother and I were “greener than thou”.

    Heck, now-a-days, if you made shirts from chicken feed bags you could say the fabric was “repurposed”. That’s even ‘greener’ than “recycled”. And look: here is hemp fabric:
    http://www.etsy.com/listing/55688054/hemp-fabric-by-the-yard-1-yard-100-hemp?utm_source=googleproduct&utm_medium=syndication&utm_campaign=GPS&gclid=CIj1sdrr3LQCFStgMgodGmIAeA

    $14 a yard.

    I’m reading the history on hemp. Those chicken feed bags may not have been hemp. Laws.. you know…

  15. Doc

    She was a little lady, with a large bosom, and couldn’t get dresses to match her age.

    That would match Jim’s mom. She is very busty. She made most of her clothes until she reached the age of… oh… 60. Then she must have tired of making them. Also, she went fro 82 lbs to 100lbs, and I think most of that went to her bust. So the alterations likely became more challenging. I think she was fine as long as all she did was add width at the bust. But my impression was that she never understood how to alter bust darts properly.

    She was better at construction than I, but I understand how to alter patterns for fit better than she.

    She did have a beautiful dress made for our wedding. I know she could have done all the construction work because I saw things she made. I don’t think she knew how to alter the darts though. (I would have been the opposite. I haven’t ever made pretty lace where you care about how the seams look from the outside. )

  16. Lucia, surely an open thread could lead to a disaster in the trouser department.

    I would recommend tying off all loose ends.

  17. Re: j ferguson (Jan 9 20:20),

    with intent to having accessible code to see if I can get the “wow” out of the steering in a following sea that’s very annoying in the present system.

    I would say that a GPS and magnetometer will be required. What you’re talking about would seem to be yaw control. I think you need separate references for the boat (magnetometer) and the Earth (GPS) to reliably calculate the difference between where the boat is pointing and where it’s supposed to be going. This would probably be similar to the problem of wind gusts while flying. Gyros will do it but gyros plus magnetometer will do it better. See this: http://www.youtube.com/watch?v=C7JQ7Rpwn2k

    Also, have you seen this: http://code.google.com/p/gentlenav/

  18. DeWitt, thanks for the thoughts. I strongly suspect that the magnetometer on my present autopilot is not tilt- compensated. I can see the bearing information change as the boat pitches forward in a following sea, even though the actual heading doesn’t change – If I’m running the autopilot with the clutch disengaged and steering by hand.

    Obviously the boat also pitches headed into the sea and clearly there would the same sort of tilt-error, but because the time spent at that pitch is much less, the effect is less.

    When I was starting to fool with this, I bought a 2 axis magnetometer (no tilt correction) and mounted a 3 axis accelerometer on the same board, swung it and tilted it and recorded actual heading, indicated heading, and the tilt numbers. I thought I’d fake the tilt correction by curve fitting. Dumb me, it took a 9th order polynomial to get anywhere close to the action. I never thought I could code it without a screw-up so made a simple look-up table for the range i actually needed, and that’s what i would have used if i hadn’t postponed the project for a while and then discovered that I could buy a tilt compensated chip – just a few more bucks.

    My suspicion is that I need faster slewing when the boat is pointed downhill – I’ll try that in code.

    the problem of exaggerated heading hunting in a following sea seems to be common to a lot of autopilots for smaller boats – I hear about it all the time. I just don’t buy that it cannot be fixed.

    Lucia, When I worked with Jim Sr. in the late ’60s, a lot of us weighed less. I was 6-3 and was about 150 lbs. Alas, long ago – but I think I can get down to less than 200 if I keep the food intake down.

  19. Re: j ferguson (Jan 10 09:42),

    My suspicion is that I need faster slewing when the boat is pointed downhill – I’ll try that in code.

    You need three axes for the accelerometer, gyro and magnetometer to do proper sensor fusion for orientation with data rates at 30-100Hz or better. In the video I linked, adding the magnetometer significantly speeds up the response time to a direction change and improves stability. Now if you’re trying to control a model helicopter, a magnetometer is essential for orientation when hovering. That gives you the orientation of the craft. Then you need the GPS to tell you where you are.

    Have you heard of direction cosine matrices or direction quaternions? Roll, pitch and yaw (Euler angles) don’t commute. Kalman filters are also popular for sensor fusion, but not trivial to implement. Most people use complementary proportional integrating filters.

    True. But he pretty much stayed slim until he began accumulating fluid near the end. That wasn’t ‘real’ weight though.

  21. Hi Lucia, I’m Tom a first-time caller but long time fan… Oh, wait. Wrong show.

    Hi Lucia, I’m a 32/30 pant size, 5’8″ and 142 lb. I just wanted to note that thigh pockets of the correct size to hold a cellphone are actually pretty cool. Especially if they have a buttoned flap.

  22. thomas–
    I’m hankering pants with a calf or thigh pocket that holds the small day planner that I need to carry to Women of the Moose meetings. I hate carrying purses and I’m lugging:

    1) My flute because I’ve been appointed “WOTM musician”. (I play one and only one song badly. I need to transpose the score down a third to accommodate the untrained alto voices. )
    2) My collapsable music stand.
    3) Various the day planner.
    4) Wallet.
    5) Various bits of junk periodically requested. (Pies, cookies etc.)

    The wallet fits in my jacket pocket along with my thin gloves. I can carry the flute, music stand, and cookies. But then that dang day planner. It’s small, but it doesn’t fit in the pocket and… argh!!

    I may need a special sized “hold the flute and music stand bag”. Hmmm.. This is going to get out of hand….

    I”m thinking of doing that. . .

  23. SteveF (Comment #108282)

    Steve I could not pass up the opportunity to be able to say “we are talking sewing here”.

    Lucia, I bought two rather expensive suits near my retirement time and have worn them little since give or take weddings and funerals. I have told my wife that I do not know how much the styles of those suits are out of fashion and thus will never be self conscious in wearing the suits and attempting to get my money’s worth out of them. We recently were downtown Chicago and were looking at suits in an upscale but failing men’s ware store and not to buy but just to see the fashions and prices. The styles I saw were not appealing at all to me or, more importantly, my wife and the prices allowed me to estimate what my suits would cost in today’s market. That price I judged would be rather more than the general price inflation would predict and certainly not like computers or TV prices.

    This is a long way around asking you about the potential payback for making expensive clothing items like men’s suits. I have possibly overestimated what has been automated and the potentials with modern day sewing equipment. Is it possible for an unskilled person to purchase the proper equipment and be able to make expensive clothes items or would a better course for someone looking to save money without the necessary sewing skills to look for purchasing these clothes from the shops you hear about located in China or other low cost nations?

  24. j ferguson,
    “the problem of exaggerated heading hunting in a following sea seems to be common to a lot of autopilots for smaller boats – I hear about it all the time. I just don’t buy that it cannot be fixed.”
    .
    I don’t think it can be fixed. My Garmin autopilot faced tough conditions the other day (4+foot trailing seas) and it did a bit better than I can do manually under those conditions (brief deviations from desired course of up to ~20-25 degrees when being overtaken by a large swell). The response of the rudder under autopilot control with a large deviation is ~5 seconds lock to lock, or ~2.5 seconds from neutral to maximum in either direction, which is not too shabby, but the rudders are just not able to supply sufficient compensating force to avoid substantial deviation with significant trailing seas. The autopilot is not “hunting” (oscillating); the boat is just forced off line by the trailing wave, and it then takes a few seconds to return to the correct heading. I suspect that a boat would have to be both stabilized to roll and have much more “turning force” than rudders can generate to hold course under those conditions. The Garmin user’s manual is pretty clear: even when the autopilot is properly tuned, if you would have a difficult time holding course, so will the autopilot; if you can easily hold course, so can the autopilot.

  25. Re: SteveF (Jan 10 12:57),

    You may be talking about different things. Course deviation is inevitable whether from waves acting on a boat or wind gusts on a plane. Hunting, in my book, would be oscillations in heading when returning to the desired course. That’s usually the a result of over-controlling and should, in principle, be tunable by changing the control algorithm.

  26. DeWitt,

    I think we (j ferguson and I) are talking about the same issue: trailing seas make it very difficult to hold a course at relatively slow speeds. This (as j ferguson noted) is widely recognized as a problem in boats which are not longer than the wave spacing (peak-to-peak), and which are being overtaken by the waves (waves moving faster than forward speed of the boat). Under these conditions, there is a strong tendency for the bow of the boat to “plow” into the sea and the stern to to be pushed to one side or the other by the advancing wave. If the waves are breaking it is worse… even dangerous. When piloting manually, you end up having to make huge changes to rudder position to counteract the angular deviations, and it is just about impossible to stay on a reasonably straight course. An autopilot can do a little better because it can move the rudders faster (and does not get tired!), but it is far from perfect. If the boat is sped up so that the bow stays on the rising portion of a wave (running exactly at the wave speed, and not being overtaken by the waves) the problem disappears. When the boat outruns the waves (starts to “surf” down the front side of the waves it overtakes) you get some of the same problems with bow “plowing”, but much reduced compared to when the waves overtake the boat.
    .
    I do not see the problem as related to “tuning” of a control loop; there is no tendency for my boat to oscillate heading due to the autopilot under any sea conditions I have seen.

  27. SteveF and J Ferguson, ““the problem of exaggerated heading hunting in a following sea seems to be common to a lot of autopilots for smaller boats – I hear about it all the time. I just don’t buy that it cannot be fixed.”

    That would require a throttle and/or trim tabs control feature I would imagine and depends a lot on the hull design.

  28. dallas,

    For sure a throttle mechanism to hold the boat exactly at wave speed would eliminate most of the problem. I have even read suggestions for doing this manually in large following seas if you need better directional control (like at inlets). Hull design for sure could be important…. a deep displacement-type keel would seem to help, but my boat does not have one. Donno about trim tabs; I think they are mostly useful at much higher speeds than when being overtaken by trailing waves.

  29. I need to think about the trailing sea problem some more. I have a single screw boat with a fairly large rudder and can hand-steer it far better than my autopilot in a following sea. I need to be more specific about my complaint, though. The following-sea wandering under auto-pilot control is of much greater magnitude than I would expect. But it does seem as though it’s trying to steer with incorrect heading information due to lack of tilt compensation.

    I don’t know if this thing can be profitably pursued without more testing – Thanks much for the ideas.

  30. j ferguson:

    But it does seem as though it’s trying to steer with incorrect heading information due to lack of tilt compensation.

    That sounds plausible. A six-axis accelerometer would be ideal here. Maybe consider something like this?

    http://www.invensense.com/mems/gyro/sixaxis.html

    To be clear, I’d instrument the boat, and record data when you have a following sea. Keep a log book and note the time where the auto-pilot wander occurred. Since you can see acceleration as well as pitch, roll and yaw, you can see if which occurred first.

  31. Re: Carrick (Jan 10 21:08),

    six-axis accelerometer would be ideal here. Maybe consider something like this?

    Modern smart phones and many other devices already have those built in. And there are apps to record the data. For iOS, devices there’s the Sensor Data app. I’m sure there’s something equivalent for Android. Smart phones often have three axis magnetometers too as well as an onboard GPS. They have to know which way is up to orient the image. The overlay for this video was produced on a fourth generation iPod Touch using data logged from the internal six axis sensors and an attached GPS dongle to get higher precision and update rate as well as a link to the engine management computer for throttle and RPM data.

  32. Re: j ferguson (Jan 10 20:47),

    But it does seem as though it’s trying to steer with incorrect heading information due to lack of tilt compensation.

    When your vehicle/boat/plane can rotate around and accelerate along all three axes, six axis data aren’t just nice to have, they’re required. You have to convert from the vehicle frame to the Earth frame and back again to navigate. You can’t do that without orientation data.

  33. DeWitt:

    Modern smart phones and many other devices already have those built in

    Not owning one of those, I keep forgetting that.

    One of the groups (seismologist types) involved in our deployment last spring used some iPads to augment near field measurements. The screen on one of them got cracked by flying debris.. but kept running and collecting data.

    Anyway that’s a good idea.

  34. Can’t comment much on sewing as the only thing I sew are uniform patches but I just finished watching “Rocky” and “Rocky II” on Blu-ray. I’d forgotten just how good the first two films were, how great you felt about Life when the credits rolled.

  35. J ferguson, Carrack, DeWitt,
    My autopilot has tilt compensation and accelerometer data (both magnetic field and accelerometer are three axis). I have confirmed that the heading data does not change due to pitch or roll, and the magnetic reading is always within a degree of the GPS calculated course. There remains considerable deviation from target course at low speed in a following sea which does not appear related to incorrect heading data, so at least for my boat the issue seems to be inadequate rudder force under those specific conditions. Since j fergurson can hold course better than his autopilot (I can’t on my boat) under trailing sea conditions, there would seem to be an opportunity to improve the behavior of his boat by improving heading data accuracy and/or increasing response rate of his rudder.

  36. Hi Lucia,
    How did you discover your cat was diabetic?

    Some years ago E.M. Smith ran a thread about his discoveries in purchased cat food which seemed to have caused physical problems with his cats. IIRC, he traced the problems to “fish product” which was imported from fish farming operations in China and contained formaldehyde. I think he corresponded with several of the cat food providers and I think they were not as evasive on the possibility as we have come to suspect in this age where all outgoing correspondence is run through the abogados.

    changing what he fed them provided the cure – although if the problem is diabetes, then that wouldn’t do it, obviously.

    I discovered it later than I should have. One summer, he was walking funny. His hindquarters looked like “flippers”. Turns out diabetes can cause nerve damage, and the nerves in their hindlegs go bad, then it looks like they are walking on their “foreleg” instead of their “feet”. (These aren’t the right words because cats feet are the equivalent of our toes and their foreleg is more like our calf.)

    Turns out this damage reversed itself after he was treated with insulin– so he walks like a normal cat now. (A very fat normal cat, but still… normal.)

    If you suspect diabetes, things to notice earlier:
    1) Drinks *lots* of water. (Hugs up to the water bowl constantly.)
    2) Urinates a lot. (We didn’t notice this because we’ve always had two basement litter boxes and one upstairs liter box and scoop daily and would change to completely fresh litter very frequently. Plus the other two cats went outside. So things evaporated. But if you have only 1 cat and 1 litter box, you’ll notice it’s not drying out– and that’s a sign that he’s drinking a lot of water and the kidneys are flushing the sugar out of his blood. )
    3) The urine will be fairly dilute in terms of cat odor. (It still smells, but it’s not like the tons of extra liquid has disproportionately large smell. This is one of the reasons you need to notice by the amount of dampness rather than how smelly things get.)

  38. I would like to apologise to Tiddles Fluffikins III, or whatever he’s called. I had no idea he had a condition. I should be less judgmental.

    His name is “Mo”. The main problem is he is a “cat-a-potomus”. Seriously, this cat loves to eat. If you don’t feed him, he sits on your chest and won’t let you sleep.

    He is very cuddly and has good features. But he really likes to eat.
