I was out looking for tools today and found an open-handled Jackson 12" backsaw. It really needs some love but it called to me and I couldn't turn it down for $9. However, I'm not sure I have a need for her. The teeth are completely shot and will have to be re-cut, so I have a blank slate to work with. I feel I have a full complement of joinery saws and I'm trying to figure out how to work this new Jackson in. I have the following sharp and ready to use in a rack over my bench:
Dovetail saw: 9" Gramercy 18ppi rip
Carcass: 10" Jackson 14ppi crosscut
Sash: 14" Waller 10ppi rip, 13" 10ppi crosscut
Tenon: 16" Tyzack, 10ppi rip
The obvious solution, at least to me anyway, is to refile the 10" Jackson carcass saw into a larger dovetail saw, maybe like 15ppi rip and then re-tooth the new 12" Jackson into something like 12ppi crosscut and use it as a carcass saw.
I was hoping someone might have some insight / advice. Thanks.
