Use a large straight edge and check the entire surface vertically and horizontally for gouges, dips, bumps, etc. Mark them with a magic marker. You can usually dress most of these out using a large flat file and dressing the platen while it is on the grinder.
Pyrocerm (or fireplace glass from your local glass dealer) is great. It is slicker than a steel platen, stays flatter than a steel platen and has less heat build up. I wouldn't flat grind with out it. The only draw back is there is a tendancy to have static electricity build up and you will get the static occaisional spark. You can mount it using expoxy or JB weld. Some have even used two sided carpet tape. Make sure your platen is flat before you epoxy it up or it will crack when it cures.

If you can, I suggest milling the platen flat. I did this on my Bader, then layed down the pyroceram with some 2-ton epoxy. I felt like the grooves left by the flycutter in the platen were good for adhesion. I then sandblasted the back of the pyroceram before applying the epoxy. If I don't do something stupid (yeah right) it probably will last forever.

The pyroceram platen idea is new to me. Sounds like I need to do that. My platen is worn out, so I've been thinking of making a new one. If I can find pyrocerm here I'll epoxy it to the new plate and give it a try. Sounds ideal to me. I've always glued graphite belting to my platen to make a cushion. That should still work over the pyrocerm. I'll find out.

Thanks for the new idea.

Hey Don-

Gee, haven't talked with you in awhile


I don't know if he's still got any for sale, but for some time Steve Pryor was selling cut pieces of pyroceram for just this application.

Here's a thread talking about it...

Don ("My Way") Robinson-


Gotta make some $$$ at work so I can afford to make that folder!

Between shop equipment, supplies, and Brand New Instructional Booklets ...this hobby is costing plenty!

Yeah Baby!
