Was looking over the Penrod page and seen the pictures of the surface grinding of the action. I bought a surface grinder with an 18" magnetic base, just have not got the electric hooked up to the machine as of yet. QUESTION: What are the best wheels and grit size to use for grinding actions. I have 3 Arges to do, and from the pictures it looks as if maybe more than one type is used. One is grey and he other white, unless it was the camera? If ya know and have done this any info would be of great help. P.S. I'm also going to fix up a (jig) for indexing to do these types of jobs. THANKS...

Mark Stratton's book has some good information on grinding.

22WRF: Your right it does have some good information on surface grinding, but has nothing on what grinding wheels are the best to use. I guess it'll be trial and error!

If you own the book why not give Mark a call and just ask him what he uses?

Check Norton's web site. Their grinding wheels are used buy most surface grinders in industry for grinding tooling.

ireload2: Thanks for the web sight!

Hello srtrax:

For general purpose surface grinding of hardened, or case-hardened surfaces, I'd suggest Aluminum Oxide 46 or 60 K or J VBE. Wheel spec will read, for example: 38A46KVBE (46-grit, K-hardness, vitrified bond). True the wheel each time you mount it and experiment with dressing speeds to get the finish you're looking for.
