Check op shops and antique stores for old electrical appliances as many of them used the cotton covered wire although much of it is probably badly deteriorated by now. I think you can get a fibreglass sheath wire that looks similar but don't know of any supplier. The cotton covered wire was very dangerous stuff and the cause of many a fire. There is still a lot of it hiding in peoples post war homes where it was used inside metal conduit just waiting for a bump to short out and burn their house down.
As an aside, have you had the start capacitor checked out on the motor? It may be past its use by date and need replacing before you power it up again. Be terrible to see all that hard work go up in smoke.
