I have seven Disstons. One is a shining newer saw, but the others have had the saw plates cleaned of grunge and rust.
I have crosscuts and rip saws.
Two have had the tooth line filed smooth and re-toothed. I made paper tooth spacing patterns and taped them to the saw plate.
I first file the tooth spacing, then file the rake and fleam.
Two have had broken handles replaced with new curly maple handles.
I think a discussion about old hand saws will be interesting.
This string came about as I was reading an article in Popular Woodworking about a tool test for Bad Axe D-8 handsaws. If the new woodworkers
in this group have never played with hand saws, you might want to. I find it to be enjoyable to gain new skills. Google "rake and fleam".
