making a scraper out of a washer
« on: November 21, 2012, 06:46:09 AM »
I was trying to get my larger French curve scraper down into a tricky spot on the stock and couldn't quite get it to work.  So I took a 1/2 inch washer and screwed it to a bit of wood and sharpened it up.  Worked like a charm. I'd take a picture of the little tool I made but can't seem to find my camera.

That's a good idea. I guess you just chuck it up in a drill and sharpen with a file?

I did it by hand with a file... didn't take much. Total assembly time was about 5 minutes.

 You can harden the washer by heating to cherry red, then quench in a brine solution.
Doing so will allow the washer to hold a good edge.
The brine solution is 2.5 gal. water, 2.5 lbs. salt, 16 oz. Dawn dish soap, 4 oz. Jet Dry ( dish washing solution)
This brine solution will give a good hard surface to mild steel.

I have tools that went through the fire back in August. Can they be recycled this way? Perhaps
re tempered in the oven when the wife isn't home? :D I hate to waste them if they can be reserected.

If it went through a fire it probably was completely anealed so it will need to be re-hardened.  You can't do that in an oven as you need to get the steel up to the critical point, the temperature where a magnet will not stick to the steel. You can make a simple fire brick forge with a propane torch.  http://www.paragoncode.com/shop/micro_forge/ Then it gets plunged into a medium such as oil or water depending on the steel.  After that you need to temper the steel by raising it up to a specific temperature and holding it at that temperature to reduce the stresses in the steel.  That is something you can do in the oven say after you get done baking a pie chuck the item in the oven leave it at say 350 and then let it cool down real nice an slow. 

Needed to make some corrections... typed this out at 4am...
