Thanks for all the info, I really appreciate your help. I will play around and see what I can do with it, I am a complete novice with sewing, so even at those speeds it sounds like it might be more than I can handle. My wife has been sewing for like 17 years though, she can probably work with it. Thanks again

Would it be possible to slow it down by changing out the motor and or pulley, or would that cause the oil pump to not work properly?

I thought that might be the case, maybe my wife can use it for her sewing business (If she can handle the speed it runs at) Thanks

I just acquired a used Brother Mark III SL-755-3A sewing machine from a friend of my wife, and I was wondering if anyone could tell me what kinds of leather it can handle. It looks like it would work just fine for things like garment and upholstery leather, but can it handle tougher vegetable tanned leathers? It is in good shape, but sat unused for about 4 years collecting dirt and cobwebs, so it needs a good cleaning and probably a tune-up, just trying to decide if it would be worth putting any money into it, etc. Thanks for any info.
