Having figured that I prolly can cut my own teeth on a .010" thick by 6" or 8" length of card scraper stock and then make an d mount a handle to it. I am wondering how I might make the back.
I have lots of carbide drills so drilling the hardened steel wouldn't be an issue.
The one option that stands out in my head is to make it from solid bar stock (steel or brass) drilling and tapping it and simply screwing that to the card scraper.
Any one done this - made a back saw? How'd you go about it?
