Moved your post to Dyes, Antiques, Stains, Glues, Waxes, Finishes and Conditioners. Check out vinegaroon in this forum, lots of posts and info. Note it is not a dye. It is a reaction between iron and tannins in the leather. So the leather needs to be vegetable tanned, and, any finish removed so the veinegaroon can soak in and do its chemical reaction.

You need to provide more information, like thread size and type, needle and awl sizes, and some pictures of the stitching from top and bottom sides showing examples. We may have some minde readers here, but I think they need your help.

May also depend on number of coils (magnetic poles). Did you measure with a dial gauge, or brace a pencil and bring it close to the pulley until it just touches some point on the side of the pulley rim while turning by hand, and also when running the motor? Tends to say the bearing may be damaged (possible broken or cracked outer race or deformed balls), or if the bearing is supported by spokes vs. machined full face like the video shows and 1 or more spoke is broken. This is definitely a mechanical issue (due to hearing and feeling grinding noise speed and belt tension changes). Reminds me off a vibration analysis job on a large cooling water pump. Driver was a steam turbine running around 7000 RPM. The story came together in pieces. You only get told what they think is relevant. The turbine had tripped on overspeed. They rebuilt the governor and put it back together. Now it had high vibration. They had a spare turbine rotor in storage so swapped it out. Still had high vibration. Then they called me. I took vibration measurements on the turbine, gear reduction box, and the pump. The pumps operating speed was about 500 rpm. The vibration on the high speed pinion shaft was approaching 100 in/sec, fantastically high and dangerous. (1 in/sec is bad.) I got out of there as quickly as I could while capturing the necessary vibration data. The vibration frequency spectrum showed peaks at the turbine speed and at the pump speed. The highest peak was at the pump speed. So I told them the pump / bull gear shaft was bent. They replaced the gear box. Still a problem. Told them they needed to check the run out on the pump shaft. Guess what, it was bent. Then comes the rest of the story. A board (slat) had fallen off the cooling tower and was sucked into the pump. Oh! that is interesting! The board had stalled the pump and broke up. The turbine governor had opened up wide open to bring the speed back up. As the board broke up, the turbine went overspeed and tripped before the governor could correct the speed. The board bent the pump shaft before the board broke up. The unit was about 1200 hp. Pump suction was about 20" or so diameter.

Try heating it up fairly hot. Often that will soften Loctite and other thread lockers (and many glues / adhesives).

I moved your post to leather sewing machines. You'll get more interest in this area. Have you looked through this forum? you will find a number of discussions about servo motors.

Hi Jeff. You need to add shipping information. Will you ship, where to (world wide?), who pays.

Moved your post to suppliers

Then there is the guy that was using an electric drill with a wire brush. He had an itchy spot on his head, so gently reached up with the drill to scratch his head and bumped the trigger. There went a good chunk of his scalp!

Try 20 feet with an extension ladder sliding out from under me. Landed on my feet, crushed right ankle that the MD couldn't even bother to look at the x-ray or radiologists report. Came down between 2 rising stem gate valves on 6" lines. Right side of my shirt was ripped open, slight scratch on my chest. Could have ripped my shoulder off if I had been a few inches further forward. Very thankful that didn't happen. The ankle was bad enough, limped for 15 years. Still can't bear to lace up an ice skate to go skating 54 years later. For years, too much or too little exercise on that ankle resulted in severe pain. Had to keep moving, but not too much, We have lots of safety standards. They are there for a reason. If I had waited for my fellow worker to come back and brace the ladder before I stepped down onto the rung, this wouldn't have happened. He was called away because a couple 1000 scfm air compressors had tripped and had to be restarted immediately else the whole utility plant that supplied steam, compressed air, 54MW of electricity, utility water, boiler feed water, cooling water would have been lost and the whole process including a refinery would have shut down. We were in a isolated location 100 miles from the electrical grid. I should have just sat there and waited!

Do you lift the foot slightly so you can turn the leather without it acting like a lever and pushing your needle to one side or the other?

You need to provide a lot more information: Where are you located? This is a world wide forum. I assume you are looking for a buyer from your area. According to your IP address you are in Texas. List a reasonable amount of what you actually have. A few photos would be helpful. What is the asking price in US$? Will you ship? Who pays shipping? See the marketplace rules here https://leatherworker.net/forum/forum/70-announcements/

I'll fix the title in a few minutes.

Have you tried a search? Here is one for a 3 ring binder, you can modify the search parameters as you wish. https://leatherworker.net/forum/search/?&q="3 ring binder"&page=1&quick=1&search_and_or=or&sortby=relevancy

That's a great buy! I'd keep them all. Need a succession plan to pas them on to another person when you are no longer able to use them so they get put into the hands of another person that will value them. None of my kids or grand kids are interested in leatherwork so I need to figure out what to do with all my stuff before too long.

Post the video on YouTube and link to it here. Need more than 5 seconds that fits file size restrictions here.

Wow, lovely machine!

This was done to improve security for the site and user accounts. When someone can pull your username off one of your posts, then they can run software against it to try several thousand passwords that have been collected by nefarious jerks to hack into your account. We were seeing new posts on very old threads by a user that hadn't been on the site for many years. They were posting spam links obviously with no relationship to leather nor anything useful for members. It may take you a few keystrokes more to use your email address versus your username, but it has secured your account. People that are logged to this site (with the exception of admins and moderators) can't see your email address. Thus not as easy to hack into your account. Cyber security has become extremely important. It is critical to protect your private information. This is just one step in that direction. Too much info on the web makes it easier for hackers to get into your accounts, whether it be your bank account, or other social media accounts, eventually leading to your bank, Amazon, or other accounts that have access to your banking and credit card username, passwords, PINs, etc. There are news items about compromised accounts at least once a week, and likely several every day where people have lost thousands $ when their financial information was compromised. Practice safe computing.

I read your post earlier this morning, but had to go out to an appointment, plus other stuff, so just got back to it now. So I looked around and found what you found, and was about to post it with some screen captures. Then I see you found it too! Good hunting.

We have one somewhere in southern Alberta like this, except it has a large cannon ball on the end of the chain. Couldn't find the photo last time I searched for it, so maybe it's gone, got blown away!

This post is 2 years old and the OP hasn't been on the site since September 2023. It should have been in the Marketplace forum. For sale items are closed when sold or are over 2 months old. I'm locking and archiving this post in the Old/Sold area.

Maybe we should kick them off if they can't be bothered to check for a response. They certainly aren't contributing to the site! @Johanna

Yes, I noticed that. He may not have notifications set correctly, so I quoted his post so he should get a notification due to the quote.

Moved your post to Leather Sewing Machines Argued with myself as to whether this should stay in history or move to leather sewing machines. Guess who won?

Moved your post to Gun Holsters, Rifle Slings and Knife Sheathes

In the future, please post your photos here. 3rd party hosted photos frequently disappear due to changes in the host's policies, host out of business, users moving files, deleting files, closing their account or the account expiring. When this happens, the post becomes worthless to all future users who are researching or looking for help to solve a problem. If your files are too large to post here due to file size restrictions, you need to resize your files to fit. Please use jpg or png format files as they load automatically when the thread is opened.
