JoeD,
I used PM-C1018ON Marshallcrat (C1018) Low Carbon Onsize Ground
Flat Stock to make my scraper bits.

This is the low end quality. But, in scraping,I never make pressure
cuts. They are light barely discernable when I do it other than
watching the obvious fluff that comes off of the bit. So I rarely get
the bit hot.

On my scraper bits I gring one end with a radius point, probably about
a 1/8th radius. The opposite end ground to a 1/2" radius for the
actual finish scraping. I have a hole in the middle of the bit. When I
need to remove heavy cut lines I use the 1/8" end. Then when I am
ready to impart a smooth wall I reverse the bit 180 degrees and take
light passes. A two in one bit.

You can get better steel, A2, that will hold an edge longer, but with
the proper releif angle on the scraper bit it does a fine job for a
long time.

I'm a very frugal person, by necessity. I dont have a nifty retirement
plan and oodles of time to figure out what I will do each day. I am
still trying to figure out how to pay two mortgages and a car payment
on unemployment.

Cad, I really appreciated your description of how to heat treat tools.
I've read about it before, and always felt it was too confusing.

I have a very basic question. When you go to toolanddie.com's web
site, they offer ground flat stock in O1, A2, 4142, etc. Are these
considered HSS? I am looking for 1/8" thick scraper bits for a Basham
tool.- Hide quoted text -
