Stripping a plate

[Wayne Walker]

Try a high pressure washer, it may work and leave plate in better shape than
sand blasting. I sandblasted a plate years ago and it needed fill to smooth
the surface. It would be worth a try, you may be able to rent a unit.

Subject: Stripping a plate


Hello all you who do your own plate finishing,
 
I haven't had much trouble in this regard until now. We have a spray booth
and have always sanded and finished our own plates. However, there is a
plate in the shop now that was previously refinished (with I don't know
what), and the finish is severly cracked. We have tried sanding down through
it, but it doesn't seem practical or effective - the cracking is all the way
through the finish. I want it all gone, so its unknown qualities don't
affect the new finish. We are thinking our only choices are to strip, or to
sandblast. 
 
Has anyone had experience with either? The only other plate we stripped
completely was years ago, and I remember that it took off the original
japanning as well as the finish, leaving the original roughness of the
casting, and took an awful lot of hand work and fillers to smooth it. I
expect that sandblasting would be more controllable as to depth, but I don't
know if it would leave a smooth enough surface. Any ideas? Any?
 
Thanks,
Bob Davis
