Thanks Glenn,
I've just got through reading all 55 pages going back to the first page often. I thought I had read some where in the thread you had used that paint for the edges. I have the 15-90 I'm just wanting to clean well and use. My 31-15 is a different story. Someone has painted it with a brush a nice gloss black with ridges somewhere in it's past. I think I'm just going to strip it then prime and paint with auto enamel. Maybe a coat of shellac on top, but most likely just a coat of wax for protection. Since this is to be used as a heavy sew machine I just want it clean. The problem I think I'm going to have with it is the taking it apart to strip and not getting it back together where it will sew. Do you know where I can get a good service and adjustment manual for the 31-15. Is there a generic manual that tells you the principles of the vintage machine working.
Thanks
