I am looking at purchasing an American straight needle industrial sewing machine that is Available in my state. From the online pictures, it looks to be a bit dirty, but according to the posting, it “runs good”. I’m pretty sure I would like to have a needle and awl machine, as I stitch a lot of heavy leather, but I don’t know a ton about them. All I have had so far is a Chinese shoe patch machine, which I have tuned and modified so that it runs well (size 23 needle w/207 thread). The price is around $1000, so I assume it may need some work. Any info what to look for on mechanical issues, parts availability, etc. would be greatly appreciated. Thank you all!
