I'm doing a saw re-hab project on four different Disston saws. It's really interesting and fun to compare the saws, handles, wood and finishes on all of these. Adds another dimension to a re-hab project. But I have a question that you saw experts can "handle", I'm sure. Here are the subject handles, with labels indicating the saw they came from. I made the picture big on purpose (apologies for making you scroll ).
I tested mineral spirits and denatured alcohol on all four. The only one with a reaction was the #77 backsaw handle, which got gummy when in contact with the alcohol, which means it has a shellac finish. The other three did not seem to react much at all. I figure the D-112 handle didn't have much finish left to react, so that kinda made sense.
But the two more recent saws, the D-42 and D-15, both Victory saws, didn't react to either mineral spirits or denatured alcohol. The finish on both has flaked off in some areas, but what remains is hard and very well attached. It has a kind of crinkled look to it, which makes me think shellac, but I don't think it is. In some areas it has a gold sheen to it, mostly on the edge of the handles. In general, this old finish is ugly, mottled, and masks the grain of the wood. So it's coming off, one way or another.
I prefer gentler methods, but I don't want to use commercial strippers as they often leave discolorations and blotches. I'll use sandpaper if I have to, but only as a last resort. Any ideas from you saw handle finish experts? What is the finish, and what's the best way to remove it without causing damage? NOTE: These will be user saws!
