Thread: Cutting Saw Blades Into Scrapers Question

A 1mm thin disk in the grinder would be the go I'd reckon. Others may have better ideas.

Cheers

Like Enfield Guy said , the 1mm cutting disc is how I do them.
I draw out what I want with a black texta , and clamp the saw blade down to a scrap board first, then cut them out.

Yep, wot the others said, except I usually clamp the plate between two bits of steel bar. You have a guide to run the wheel against, and the steel acts as a heat sink to eliminate any chance of overheating. For shaping curves, use the grinder. If you take gentle sweeping cuts with a clean wheel you can remove a lot of metal quickly without heating it dangerously.

Out of curiosity, I have cut 0.8mm plate without clamping betwen steel, and it doesn't make much difference on larger pieces, if you cut cleanly & quickly, because the heat dissipates very quickly from the thin metal. However, it does matter when cutting thin strips liike for bowsaw blades - without the heat sink, thin offcuts turn into spaghetti. You will notice when you use a file to smooth the cuts made by the wheel that there will sometimes be some hard patches caused by local hot spots, but these are only a couple of thou deep at most, and the rest of your piece remains at the proper hardness.
