2" equals 50mm (actually 50.8mm) so is considered the same size. With your Consew, you are not sewing 3/4" of leather, so don't need the higher wattage/horsepower. Depending how slow you want to go, you still might want a speed reducer pulley set. But why not test the setup with your servo first and see how it behaves before spending the extra on the speed reducer? Tom

Rub some wax into the zipper. Often helps. Stiff zipper is sometimes due to a little misalignment between the 2 sides. Tom

This is what happens when 3rd party hosing is used and the files are moved or permissions are changed. There is plenty of room on the server to accommodate storing your photos here. If they are too large, reduce the file size. When pictures disappear from a thread, it becomes useless to all. @Deemer Please upload your photos. Thanks. Tom

@RJLamie moved your post to Leather Sewing Machines (instead of How do I do That.) Likely to get more visibility from sewing machine people here. Have you looked in Marketplace under used and like new sewing machines? Tom

Is that like "slow boat from China"? Sorry, couldn't resist. Tom

Patience is a virtue! We are not sitting here waiting for you to post. We are all volunteering our time and knowledge. We have a life outside of this forum that is our primary focus. Tom

My comments work for a typical machine. Never used an Aerostich, and recognize that its operation is mostly on/off type thing. So I'm not sure how you would manage ensuring the hook has caught the thread before turning. Look at his video at 4 minutes to see how to turn 90 degrees. He also mentions a needle down operation for lining up with a hole or position earlier in the video. Hope this is of some help to you. I notice some other videos too but haven't looked at them. Tom

Needle should be down, but starting to rise, maybe a 1/4", so the hook has grabbed the top thread so you don't get a skipped stitch. Don't raise the foot so far that it releases the top tension. Turn piece 90 degrees and keep going. Tom

A photo might help people visualize what you have and enable them to make comments. It would be nice to know where you are from or where you obtained them. That could help too! Tom

To do this type of repair without disassembly, the part needs to be turned on a lathe, then a diagonal cut made through the new piece, then glued into place with the diagonal cut carefully aligned. A careful job will leave just a hairline where the diagonal cut was. Tom

Reduce the file size. Tom

@laether Lots of post about servos. Try a google search "site:leatherworker.net servo" without the quotes. Add additional words to refine your search. Tom

@tieflyer Please read and conform to the Market Place rules http://leatherworker.net/forum/forum/70-announcements/ Add photos and full description. Thanks. Tom

@teatree I assume you are requesting help with a sewing machine. Perhaps you could provide a bit more information such as the type of machine and what you need. I'll leave the post here for the time being until we hear back from you, but think it would get more attention if it was placed in the sewing machine forum. Tom

You are probably trying to push the presser foot through the plate or feed dogs. I would suggest that instead of randomly trying these adjustments, you obtain the service/instruction manual and go through the complete setup, starting witht he outlined sequence. It must be making more noise as it runs as well instead of a nice smooth operation. Tom

Industrial strength is a mis-nomer. It's just a old steel domestic. Have you read this post? Tom

@GaryTullos Up to about 3/8" roughly. Tom

@Patti Moved to marketplace ... Tom

@LeHoang @mattattenborough Matt hasn't been active since Nov 22, 2017. Only a single post. Tom

Switch directions after the needle has risen maybe a 1/2", but before it rises above the surface of the leather. Reversing directions before the hook has caught the loop may result in a skipped stitch and a bird's nest on the bottom. Tom Edit: That should be 1/4"

I have found places that sell quantity lots, so instead, went and bought a binder with the size of rings I wanted and took them out and trashed the cheap cover. Tom

Depends a lot on what you are looking for. What type of patterns? Bags, holsters, carving/tooling, Etc. http://www.bighousedaddy.com/ is one that came up recently on another thread. Tom

Have a great retirement. Pop in once in a while for an update. Show off the kids and any new leather items. We appreciate your work and advice. Tom
