Been meaning to make my own rasp for bows. I don't have a forge. Here's my idea:
1. grind an old file flat;
2. heat the metal with a torch gun;
3. stitch it while it's hot.
What kind of chisels are used to stitch it? Haven't found anything on the internet.

There is a little shot of this guy raising the teeth on a rasp.
Everything else I can find is making knives out of rasps. I know I saw good pictures in an old book, but since I can’t find the book or remember the title, that’s useless to say the least. If I find the info, I’ll be back.

Just tried to stitch a Soviet file. without heating. Too hard. Can't even make a dent. If I heat it with a torch gun and stitch while it's hot, do I need to harden it afterwards?

Yes and that leads to my question. Once you've stitched it and it's time to re-harden it, doesn't the heat take the edge off the teeth? Is it a very precise temperature requirement? I can see burning the tips off the teeth as a very real possibility.
