American Straight Needle Tension Issue
dikman replied to cgleathercraft's topic in Leather Sewing Machines
I suspect you're right about the tension being the problem. There's really no reason for the timing to go out unless something dramatic has happened. -
Thanks Gregg, you've just increased my knowledge on this machine significantly. I was under the impression that it was probably the first of the model range, but it looks like it was possibly the last, as the Consew 206-RB5 is the same machine. It would certainly suit my needs, but I think the seller wants too much and I said to contact me if she decides to drop her price (which she said was firm). The problem is that she said that she has to sell it because of a lack of room, but has admitted that she doesn't really want to sell it!! The solution being to put on a high price, I guess, and see if anyone is silly enough to pay it. Still looking......

I've got my eye on an STH-8BL. Trying to find info on it isn't easy, as I suspect it's the first model in the series and so is fairly old. (It has a rotary dial for setting the stitch length, whereas every other one that I've seen has a slide lever). I've seen it referred to as a "compound feed", but have no idea what this means in relation to this model. Can anyone shed any light, or thoughts, on this model?

Thanks 276, a search for the Ho Hsing in Australia didn't turn up anything, nor did ebay. Ordering from the UK isn't an option for me, as the shipping would be a killer! (The advantage of the Chinese motor is that it's free shipping, it appears that they have a warehouse somewhere in Oz so it's effectively shipped locally). The reviews from customers are good, so I guess the only way to find out is to buy one and I guess it's probably worth getting the needle position version, given that it's not much more.
-
I should have added that it's $50 more for the needle position version, so, is it worth it?
-
I've been looking at servos on Aliexpress (Chinese version of ebay?). Some of them come with "needle position and synchronizer". Assuming that it does work, is the feature of any practical use to the non-commercial user? (Meaning me).

Timing issue between the hook and the needle? -
American Straight Needle Tension Issue
dikman replied to cgleathercraft's topic in Leather Sewing Machines
Based on what I've gleaned thus far in my sewing machine journey, my first thoughts on seeing the bottom photo are - bobbin tension too high, upper tension too low or needle not big enough (hole not big enough to pull the bottom thread through). I'm curious to hear if my reasoning is right. -
For $2.50 you can't go wrong! They should be fine for thinner leather. (I had a "cheapie" pair for years, and they were working fine until I tried to punch a thick holster - they shattered!!!).

Just to add my experience with mutton tallow, I made some about 18 months ago to use with my muzzleloaders. It's stored in an open container, inside a cupboard with my other waxes, and the cupboard is inside my forge shed. This shed is a basic tin shed, which gets very hot in summer (no cooling of any sort) and so far the tallow has remained fine. The beauty of pure tallow (and mutton tallow is supposed to be the best, made from suet) is that it doesn't go rancid.

As a result of this thread, I've made two holsters and a belt without grooving. I have mixed feelings about it. Personally, I think the grooved stitching looks a little neater, but there are problems when using this method on anything but nice simple lines. Freehand grooving (when stitching a pattern) is a pain to try and get it neat, it's very easy to mess it up, grooving the back of a holster can be problematic when trying to get the awl to come out in the rear groove and although I haven't tried machine stitching when grooved I had already deduced that it would be very easy to make a mistake! I'm guessing that I may not be doing as much grooving as I first thought.

I don't know anything about the Tandy classes (don't have them here), but I learned by reading LOTS and LOTS on the 'net, the guy where I bought my leather gave me lots of free advice, I watched quite a few videos on youtube (yeah, I know, some are pretty basic, some are self-indulgent and some are downright pathetic - but they still helped me understand some of the terminology and what people were talking about) and then there's this forum. An incredibly valuable source of information and advice. I've also read a few books, some by Al Stohlman - your local library might be a good source if you don't want to buy them. And then I learned by doing, and making the inevitable mistakes. If you still want to do the course, I would advise that you start reading to learn some of the basics first as it should help you get more out of the course because you'll have some understanding of what they're talking about. Incidentally, they mention buying the "basic tool set", but I think you would be far better off buying the individual tools as you need them. (I bought the basic set - awl, groover, marking wheel thingy, needles and thread. It got me started, but I've never used the wheel thingy, the thread is too short to be of much use and I eventually managed to pull the awl blade out of the handle! I fixed it, but I've ordered an awl from Japan, as while the Tandy awl works I've realised it's not exactly the best example of an awl). You have a big advantage now, being retired - you have the time to spend learning!
-
Yep, you're quite right, Uwe, and it applies to many items. A little while ago I bought a plasma cutter, and virtually all the brands/models available here are from China.The gentleman who sells the brand that I bought (his brand) said that he carefully selected the factory that makes them and personally visits the factory at regular intervals to ensure that they're doing what he wants. It shows, as I opened it up and the build quality is excellent.
-
I may have to take back what I said earlier. I read the whole document this time (I stopped at the shuttle timing last time) and it's somewhat more complex than mine! The bits to check are the needle bar adjustment and the shuttle timing - the shuttle timing adjustment is quite different to mine. Check them out, but DON"T adjust anything unless you know it's out of whack. If you feel that they need adjusting, I suggest you put marks first on the various bits so that you have a reference where they are now. I didn't, when I got stuck into mine, and if I had I may have saved myself some grief. Photos may be a good idea too. And yeah, when you change materials the tensions may require tweaking slightly (I figure webbing may be particularly problematic, due to the varying thickness i.e. material and "holes"?).

Seems to me that if he wants a "rough look" then leave it as is, so that it will gradually acquire a nice used look about it.

Unless you're very lucky and can find a suitable machine at a bargain basement price, be prepared to spend a decent sum on something that can sew leather. Look in the "sewing machine" section as a starting point. The minimum you will need is a walking foot, and ideally a compound feed walker. You could always hand stitch it - might take a while, but then you can amaze your friends by saying "yep, I made that, all done by hand".

Bullet Loops On A Sewing Machine.
dikman replied to glockanator's topic in Gun Holsters, Rifle Slings and Knife Sheathes
I've watched that video a couple (!) of times, and found it most informative - but it was certainly painful to watch, as he "fumbles" around a bit. JLS raises a point that I also thought of, i.e. the bullets rubbing on the diagonal stitching. It seems to me that it would be a good candidate for running a groove on the diagonal line? -
Thanks cd, that makes sense (we tend to think in terms of leather on here and it's easy to overlook other materials, I guess). Looking at your list of classic machines, I see that I've got one that you haven't .
-
That stitch looks pretty good to me, considering you're sewing webbing! That document I mentioned has info on setting the hook timing - although it says "parts list" it has more than that in it. I had a quick look as I was curious (it's different to my machine). I can't help with the cutter, as I'm not familiar with them, although mine had an automatic cutter which cut the excess material from the seam as it was sewed - I removed it as 1) I didn't need it and 2) it was one more complication I could do without! As long as the machine is working mechanically, virtually all problems, in my experience, will be due to thread tension and/or hook timing. Spend the time to make sure the hook timing is correct,
-
Yeah, I got a pair of those too, impulse. Seemed like a good idea, for the price, but I've found them to be too much magnification for my needs! Still, didn't cost much to try. (Been a bit wet in the hills lately, hasn't it?).

I have discovered that getting the thread tension is critical. The bobbin tension, in my experience so far, has to be a lot "looser" than I would have expected. I spent a lot of time just turning it by hand, watching the bobbin and the hook in operation, and experimenting with thread tension. I also had a problem recently with something catching individual strands in the thread, cutting it and the thread partially "unravelling". Turned out that I had the hook timing wrong and the hook was catching the strands. These old machines aren't actually that complicated - but you have to spend a bit of time becoming familiar with their operation. Just found this parts list, I don't know if it's of any use - http://www.supsew.com/KnowledgeBaseArtefacts/Images/Singer%20269W.pdf

Welcome, medion, I too have discovered the paucity of information about old Singer machines. I managed to find a parts listing and a user manual for mine (51W59) and that's it! Fortunately, the user manual had the most critical bit of info - timing the hook. The rest of it I figured out by cleaning and oiling it. I can tell you that the W in the model number indicates it was built in the US. Some say that any Singer can be identified as to its build date, but this doesn't apply to the W series at least, as the records appear to be pretty patchy.

Decided To Limit My Craft Offerings. Probably Not A New Idea.
dikman replied to Tallbald's topic in Marketing and Advertising
I like where you're coming from, Don. At our stage in life we are lucky that time is not an issue when making something. It does give us an advantage over those who must try and make a living from what, to us, is an enjoyable pastime. On the other hand, I doubt if we could ever charge enough to really cover our costs when making something. I certainly can't!! I recently made two single-action gunbelt rigs for club members - one paid me with pistol primers and powder (which is fine, as it saved me buying it) and the other in cash, although he wanted to pay me more than I asked ($150 - plus materials - is nowhere near to covering the time I spent on it, but I was happy with that). I figure if I can cover my material costs and get a little bit extra, to put back into the hobby, then I'm doing well. I'm under no illusions, however, at being able to sell much, particularly as I'm only really interested in making belts, holsters and knife sheaths (very limited market). I see nothing wrong with "specialising" in particular items, as it means you should be able to learn how to make a quality item, and to make it efficiently. If it were a full-time, income-earning business then you probably wouldn't have the luxury of being able to concentrate on what really interests you. Your idea of helping others in the community to learn about leather working is also commendable, I hope it works out. My involvement in leather working, by the way, is measured in months, so you're way ahead of me. Live long and prosper, my friend. -
The wording is pretty much the same in my manual. I agree that while a 24 needle seems a bit much, particularly for anything but thin leather, I don't believe they would list them if they wouldn't work. These are industrial machines, and if they didn't work as claimed industry simply wouldn't have bought them. Not that I can see much use in such a large needle and thread if it will only go through thin stuff! I suppose it sounds good, being able to list bigger needles, even if the practical applications are limited!! (I must admit I was momentarily excited at the thought of using 207 thread, until I stopped and thought about the possible problems of using such a large needle in this machine. I'm happy enough at being able to use 138 thread, as it puts me way ahead of my other little domestic Singer). I used it today to pre-punch the holes on another gunbelt, I used a broken size 21 needle, which I ground to a point, and simply turned the wheel by hand while feeding the belt in. Worked very well, and gave me nice even holes. I did try using the motor, but even though I've fitted a speed reducer it still doesn't have the real low speed control I need and can run away very easily, particularly when doing a pattern.

I agree, while there are times when high magnification might be handy, I think 20 power will be too much for most things. Some of the head-type magnifiers have variable magnification, you just flip down additional lenses. Two of mine are like that and I find them very useful, as most times I only need low magnification.
