With the larger pulley on the handwheel, it works great for sewing denim, giving pretty good slow speed control. Still not so good for leather, however, due to the increased resistance to the needle going in. So, I made up a step-down pulley from my collection of "stuff". The wooden mounting is rudimentary, just to see if it would work - which it does. Went through 1/4" of leather ok, but when I tried slightly thicker the needle snapped in three (probably need a thicker needle for this)! I'm not too worried about that, as I'm probably starting to push it beyond its limits. The shaft is from the 201K that I gutted, turned down a smidgin to fit a couple of bearings from my spares box. One of the pulleys didn't have a centre boss, so I turned one up for it. Now I just have to figure out a decent mounting for the pulley arrangement. Steel would be nice, but will be a lot of work making the clamps/mounting for the bearings, so I'm thinking making a better one from wood might be adequate (after all, there's no real stresses on the thing).

I made card templates for mine, but it's still not as easy as it looks to get the stitching spacing nice and uniform. Like I said, nice job.

Nice work, I particularly like the gunbelt, simple and understated. (That "infiniti" stitching is a pain in the butt, trying to get the pattern even).

That is a very impressive rig. Ugly as hell, imo, but very impressive! (Guaranteed to get attention).

I found another cone-shaped spring that fits inside the original (!) so I've added that to give more tension. Seems to work at the moment, but when I ran some stitches on a single layer of 4 oz leather I noticed that if I pulled the bobbin thread (after I'd cut the thread off the machine) that it pulled through the top thread of the last couple of stitches. I'm wondering if the needle is making too big a hole. Except for that it looked good. I've also fitted a larger pulley to the handwheel. The original was 2 1/4" (inside groove measurement) and the new one is 5", so that has slowed it down quite a bit. It was still hard to start slowly, however, and would take off fairly suddenly. I then realised that with the motor off it was very hard to turn the handwheel, so I started looking at the clutch arrangement. Once I'd figured out how it was supposed to work, I got stuck into it. The friction material (asbestos?) is in good condition, but there was a high spot that was dragging when turning the pulley. The yoke it's mounted on looked like it was supposed to slide slightly, but was extremely tight. I stripped it down, lubed the slide and re-adjusted the support screws on the yoke. That made a huge difference, as it is now much smoother when it engages. If I can fit a slightly smaller pulley on the clutch shaft that should also help. A handbook on the motor would have been nice, but I can't find one. Yes, I know, a servo motor would be nice but they are rather expensive here, unfortunately. Next step is to locate some needles. It appears to use an obsolete class of needle, according to the people I spoke to, but they said to take in the existing needles and they should be able to sort out what I need.

Thanks Darren, I've seen your posts/photos on the Able 290 and wondered what you used. My winder has worked out pretty well and is mounted in the same position (the only practical place to put one). I turned down the bobbin winder shaft on the lathe and then found it only fitted one bobbin! Mine came with four bobbins, and they all had a different size centre hole, so I had to drill them out slightly!! I've also made an adjustable guide to keep a consistent spacing if sewing along an edge. I really need to experiment with making a decent presser foot next.

G'day Subelec, l too have all sorts of arcane hobbies, and have found that many things I get interested in have an initial steep learning curve. All part of the fun..... Yes, I too noticed that after applying the dye (Feibings spirit dye) the leather tends to go stiff as a board (although when making holsters this isn't a bad thing, as it helps keep the shape). I now apply a couple of coats of hot neatsfooot oil (make sure it's pure, and not "compounded" stuff), leave it for a day or so and then apply the wax finish. Lots of good info on this site - it's just a matter of finding it!

No worries, 25b (I didn't, for one moment, think you were trying to be a jerk).

In that case I'm happy to cede to your greater knowledge/experience. All this is still new to me and as I said I've been doing lots of reading, trying to learn something. It's most likely, then, that I've mis-interpreted what I read. I definitely recall reading about a type of thread that was more UV resistant, and the way it was written I thought that the V referred to that aspect. See, I've already learned something today .

What you're saying makes sense, electrathon. When I started (not very long ago) the guy at the leather place where I bought the leather said that's how to do it. Lots of videos and articles say the same thing, but I did wonder about the fact that I was cutting into the leather itself to do it. It does seem that, like many things, it's not set in stone, so I think I'll try using a creaser to give me my stitching lines. One of the issues that I've had using a groover is that if there's the slightest variation while dragging it along it makes it difficult to correct the "glitches", 'cos it's actually cut into the leather. Red Cent, I've already made my own roller (cost = $0) from a piece of aluminium stock that was the right diameter and already had a hole through the middle, bent up a frame and turned a handle down. Works fine for flattening stitches etc.

As I understand it, electrathon, the main idea behind grooving is to recess the stitches to reduce possible wear. When I first read that, it sounded fairly logical. But is it really necessary? Does it really do any good? I'm asking 'cos I don't know much about anything and am wondering if I'm wasting my time doing it.

That's one of the things I like about it - the (very) basic, agricultural simplicity. I've modified mine a bit, put an adjustment on the springs that pull down the presser foot, smoothed off the teeth a bit on the foot, replaced the spring on the thread adjustment screw with a locking nut ('cos it tended to shift), made a table to give me a flat surface next to the feed area and I'm modifying a bobbin winder from a Singer 201K (the supplied one is a joke). A very useful little machine.

Thanks Wiz, I was wondering whether that could be the case with the coil spring. Looks like I'm not finished with it yet. Oh, and there's no thread release on this machine.

25B, can't remember exactly where, as I've been searching far and wide trying to learn about sewing thread, but I seem to recall that it was to do with a sailmaking site. Gore Tenara is definitely something that I came across (odd name).

No worries, mate. That one would require a fair bit of work to make it fit!

Well, I almost got it right...... Referring to the chart you provided, 69/T70 should measure .292 mm diameter, mine measures roughly .11 mm, so it definitely aint 69. I've contacted the seller to try and find out exactly what it is that they're selling. Oh, and further searching came up with V also being used to indicate a higher UV resistance for the thread!

"Standard" tensioner? What's that look like? The parts breakdown in the manual looks pretty much the same as my 201, so I just assumed it was the same type. If there's a better one to use let me know. It would be nice to repaint it, (Singer black and gold?) seeing that it's flaking off, but that may be sometime down the track. As it's an industrial machine I just assumed that the grey finish was par for the course. I'm thinking of making a small table to fit around the "post" so that I can also have a flat area to lay the work on.

Thanks Art (I think....). So, #69 refers to the Tkt size? Which equates to T70 (Tex), which in turn equals 630 Denier.

I went out to play with it a bit more, and think I've got it! I've identified three issues. 1. I wasn't holding the thread tight enough at the start (LumpenDoodle2 was right in that regard). This was allowing it to pull back into the shuttle. 2. It needs a lot more tension on the upper (needle) thread than I thought it would need. I'll need to look at my tensioner, as it's almost maxxed out tension-wise now. 3. There is a "bobbin case lever" to the left of the hook. Its function is to turn the bobbin case very slightly, at the right moment, to allow the needle thread to slide past the bobbin case. It looked like it was working ok at first, but then I noticed that there seemed to be a very slight resistance to the thread sliding between the lever and the case. I re-adjusted it slightly (we're talking 1mm here!) and that looked like the final piece to the puzzle. I ran a quick stitch on a piece of 4-5 oz. veg-tan and didn't look too bad. I then tried it glued to a piece of 7-8 oz, the first run was ok but the second broke the needle (mainly due to the lack of slow speed control). The larger pulley I fitted actually works quite well on thinner stuff, giving me reasonable control, but on thicker material it jams if I start real slow. If I can rig up a pulley reduction system that should solve that problem. So far it's cost me $36 for the neoprene for the belt and $20 for the junked 201K (for the tensioner). Not too bad, considering what the machine is probably capable of . Thanks for all the help, folks.

The title pretty well sums it up!! I recently ordered some "#69" thread. When it arrived I noticed that the spool is marked "210D", which I assume refers to Denier rating? I then spent some time looking at various conversion charts, and researching thread designations, and came away very confused!!! So, what does "#69" mean? Does it refer to Tex sizing? If so, that doesn't convert to 210D. I also expected the thread to be thicker, as it doesn't look much different, size-wise, to ordinary cotton thread that I have. And I thought needle sizing was confusing.

I have been holding the thread, but it still did it. I think, though, that the problem is definitely the top (needle) thread being caught somehow by the pickup hook on the shuttle. That would indicate slack thread somewhere. A bit frustrating, but I figure I must be close to getting it working - I'm just not game to run the motor until I know it will do a reliable hand stitch.

So, I've got it working - almost. Made a suitable tensioner from the 201K I bought, fixed the thread guides (missing springs), re-timed the shuttle and re-adjusted the needle hook, made a new drive belt from neoprene, fitted a larger pulley to the handwheel to try and slow it down a bit (original is 2" diam, new one is 4"), re-connected the pedal for lifting the roller wheel and gave it a good oiling. Oh, and I took to the table with a circular saw (much too big!). Running without thread it punches through leather quite nicely, and while it will do 1/4" it's really at it's limit doing it. I loaded it with thread (the bonded stuff that came with it) and ran it by hand to see what would happen. The needle picked up the bobbin thread ok, and watching the shuttle it appears to be working ok, but for some reason it seems to drag extra thread down into the shuttle (through the needle hole) from underneath the material. I can get a row of stitches, but when I remove the material there are about three lines of thread disappering down the hole! I'm a bit perplexed at the moment.......

If the awl is made of good quality steel, then I'd be surprised if sandpaper or files would do much, as I would expect the steel to be hardened and tempered (if you can use a file on it, then it's what I would call pretty "ordinary" steel). An oilstone should do it, but it may take a lot of work. Best thing would be a water-cooled grinding wheel. If you use an ordinary bench grinder be very careful, as it will overheat the steel in nothing flat and basically leave you with a sharpened iron nail!

For those who may be interested, the tensioner from my 201 has the same mounting system, i.e. a shaft extends from the rear of the tensioner assembly and slides into a hole in the machine body, where it's held in place by a locking grub screw. Main problem is the shaft is too short to lock in place. I located a used Singer 201K today (this is a later model than mine and has an electric motor) for $20 (!) so I went for a drive to grab it, as I figure just buying a tensioner assembly - if I can find one - would cost me more than that. I'll strip it for parts and dump the body, as it has no real collectable value, and this should give me a good supply of the various screws that Singer use. Extending the tensioner shaft is going to be a bit tricky, however, as the rear shaft is steel and is pressed into the front part, which is aluminium!! A bit more pondering is in order........

As the saying goes "great minds think alike", Constabulary . I have a Singer 201K hand-crank unit, and looking at the tensioner assembly it looks pretty similar, so I'm going to remove it today and see what it will take to fit it. The only other thing I don't have is the thread roller which fits below the tensioner, but it may not be necessary for my needs. If I do need it, then I'll make one.
