Shopsmith Forums

A while ago, I nicked my Japanese style pull saw on a nail. Repairing the teeth on these things is impossible. plus, new blades are cheap.
Anyhow, the old blade appears to be of excellent manufacture and I hate to just toss it. Maybe a scraper could be fashioned? My extensive collection of metal working tools consists of a hacksaw and sheet metal shears. My metal working knowledge is only slightly less extensive.
Anyone have any ideas?

I don't know if that sort of blade is quite thick enough for what you have in mind, but home-made Scrapers and Scratch Stocks (like a bead-profiling scratcher) are fun to have. There's a lot you can do with a small Dremel cutoff wheel, or Al-Oxide strip sanding, some Files, or other grinding methods.

Depending on the location of your broken saw-tooth, the remainder of the blade might be usable in some short-length saw tool as well. I keep thinking of the Bridge City JointMaster (Pro) -- which is like a Shopsmith table built atop an inverted Japanese saw blade.

Chris, the bent tooth is about smack dab in the middle.
The blade appears to be as thick as the scraper that I have. The blade is about 4" wide and about 10" long.

Well, before you start it would be good to go to a nearby Trade School (oops! -- "Technical College") and chat with the head of the department training machinists and such. They might allow a student to work on it as a project]could[/B] sandwich the blade between a couple of thicker sheets of metal and cut it with your hacksaw, but...) You could probably get a couple of very good scrapers out of it.

When using a Dremel (or grinding wheel or anything else that will heat the metal), be careful and diligently avoid getting the metal hot -- doing so will diminish the temper. Additionally, you might want to harden the working edge (which the trade school folk could give you tips on doing -- or might even do for you).

Also be careful before making a scraper -- once you have one, you will be in danger of creating lots of new projects requiring a very fine finish, and prolly find yourself spending as much time scraping as sawing+joining+ gluing +sanding!

Good luck wi' it!

Thanks, Shaun. I'm going to try your "Trade School" suggestion.
