Title: Scraper temper
Post by: DC on February 28, 2019, 01:02:47 pm
I've made a scraper like Dean Torges. I made the blade from a file. It works well but doesn't hold an edge. I believe the edge is chipping. I haven't tried burnishing the edge for that reason. I just put the blade in the oven at 350f for a couple of hours. It's now a nice golden/straw colour. Will that make it better or worse. Do you think I'll be able to roll an edge on it now. I could just try it and see but I don't want to chip up the edge again.

Will a sharp file cut it?
If so you should be able to push a burr.

I took two strokes with a burnisher(side of a center punch) and now it takes nice .004" shavings. I'll have to be careful. Now to see how long it holds an edge. Thanks KH

Not sure about your fix,  but I cold ground a file to make a knife and it holds an edge like tomorrow.
I dont have a scraper, got no use for one,      I use a file, rasp, finishing sander, whatever, if I have to hog off a lot material I use the belt sander or small hand plane.   But then again I'am working lam bows,  scraping a smooth hard rock maple or oak lam is almost impossible with a scraper.   (A)

I also grew up watching my Dad use chisels, hand planes and hand augers for installing hand sets and dead bolts.  Younger people these days have no idea how to use a hand tool.  And now its CNC machines.

Have you tried using a plane on OS?

Well no those wood fibers are fibrous.  Working OS I would bring out the rasp.   Dont get me wrong nothing wrong with using a hand scraper ,  but when I see people  removing 1/4" of material using a scraper its rather Futile is it not.   :o

Yeah 1/4" is rasp work. My scraper is a cross between a spoke shave and a scraper so it's a lot faster than a cabinet scraper.
