Another possible mod to it. Use it to mark the first hole, slide it along so the circle is over the mark and mark that point on the circle with the awl. Drill a small hole and put another small pin in it, then once you've marked your first hole on the belt slide it along so the pin sits in the mark and you've got perfect spacing for the next hole. Just a thought.

Why not just loosen the lever locking screw and adjust the length of the lever until the balance is right? Or just put the weight on top of the ram?

Yep, even better!

Impressive, I admire your enthusiasm. As for the superglue, yep, sounds familiar.

Elegant and, like all good things, simple. Once I'm mobile again I'll have to make a couple.

You seem fixated on using one of the patcher type machines to make your shoes, even though the advice here is that they're not suitable. A company called Robin Industries has posted a few times on here, advertising specialist shoe making machines. Good luck trying to make a decent pair of shoes with one of those cheap Chinese patchers.

Always a good idea to have at least one backup machine. When I first became interested in industrial machines I started watching gumtree and they were regularly coming up so over a few months I ended up with quite a collection of assorted used machines at good prices! I think I was lucky because over the last couple of years the bargains (and machines) appear to have dried up. Hopefully it's just a matter of keeping your eyes open and something will come along (although waiting for a Seiko could be a long wait).

Nice collection. Funny thing, collecting, it can easily take on a life of its own.

Personally, I think those numbers that are quoted in the manuals are pretty meaningless, just something they come up with to sound impressive! You have to experiment with the settings and various pulleys to get something that works for you.

Looks pretty good to me, mate. That elk has a luxurious look about it.

I'm with Constab. I've fitted speed reducers (home-made and all different) and/or larger pulleys in lieu of handwheels to all of my machines and it gives me all the control I want. They compensate for the inadequacies of cheap/generic servos.

Yep. Dying veg tends to stiffen it, in my experience, and the glue definitely adds an extra layer of hardness. Try your awl on plain veg first, that should give you an idea of whether it's working ok.

Thanks Alexander, you explained it much better than me!

Frodo, you're supposed to poke the awl into the leather, not your finger.

On mine, which I've had for 6-7 months (?) the fitting on the top of the head, where the arm operated by the lifting chain fits in, is designed such that it's impossible to get more than 7/8" of lift without modifying this bracket. I spent some time fiddling, trying to get more lift but couldn't. Unfortunately I can't get down to it to take photos or get the book for part numbers because I've torn the ligaments in my left ankle and will be immobile for quite a few weeks. No leatherwork, reloading, shooting, lathe work, 3D printing - can't get to anything, nothing but the computer, tv and reading.

The machine looks to be in excellent condition. Those old metal machines can be quite useful as they're pretty strong. As for repairing the motor, well done! Trying to remove old potting around windings is a pain in the you-know-what!

In the first photo there is a bent spring, below the arm that is used to open the jaws, that presses against the jaw to keep it closed. So yes.

Servo can stay on as there's not much weight in them, just make sure it's secure and can't wobble around. Table upside down is a good idea if possible and definitely remove the head and pack separately. That is where the weight is and the real potential for damage.

Addictive? Yep, it can become a bit of an obsession if you're not careful. I was always on the lookout for older (bargain) machines but it started becoming a problem so I rationalised my "collection" a bit. The main problem was a lack of room!! Now my main problem is I can't use any of them since I busted my ankle.

Thanks for the link, that's cool.

I can't help you, unfortunately, but I wanted to thank you for posting the photos - it's a fascinating device. Is the idea that you stitch between the little fingers? I'm trying to figure out just how it's different to a normal pony/clamp.

I made a simple bracket to attach the edge guide using the existing holes as I couldn't see the point in drilling extra holes. My edge guides came with a small fitting to replace the roller and provide a straight edge, although it's pretty short. Didn't yours have this? I also made a lifter extension, like Uwe's, but found it was a nuisance to use, so I made up a lever system to use a left-foot-operated lever. As Cowboy Bob said it is easier to use (given the heavy springs in the 441 machines). I've posted photos in assorted threads.

Yep, could become one of those classic lines.

Nicely done - and it works!
