I was interested in trying a thumb hole saw but not knowing if I would like them I was not eager to risk much just to try one. So I saw a saw with more problems than I usually bid on with 0 bids and a starting price of .99. What the heck, I placed a late max bid for $8 figuring if I got real lucky I would at least have something I could get a feel for this saw type with. Believe it or not I got it for $3.25.
Cleaned her up a little earlier tonight. It is fairly sharp and cuts quite well as is. It is a 26", 6 ppi rip. I think I will finish restoring it and keep it for construction work in the building we work from on our property. The only real problem with the saw functionally is the teeth are not properly jointed. The teeth on the toe and heel are higher by maybe 1/4". Since the problem is only in the 4-5 teeth on either end of the saw it does not hinder the way the saw cuts much.
I was thinking I would joint just the teeth on either end, rebuilding them with a lower profile, as most of the teeth seem to perform very well. If I can't get enough off the two ends in one try I am thinking I will leave them a little long until I need to sharpen the whole blade. Does this seem like a reasonable approach to you more experienced saw sharpeners?
