Stainless steel by the Plaster-of-Paris method

[Michael Hunter]

This is my first big job using the Plaster-of-Paris method - who needs a fibre laser?!

Not only does the method provide good contrast, but the marking has bitten into the metal surface - you can **feel** the lines.

The protractor piece is about 15" square, the sizes under "tube diameter" just 0.064" high.
All lines and text are vectored.

I'll bite, "what the Plaster of Pairs method"?

Gary,

It is a thin mix of PoP applied with a brush evenly. Has the consistency of something between milk and cream. Then engrave it.

Do a search on Plaster of Paris. There will be a thread about 5 or 6 down from this one that shows up and has a discussion and details. That is how I know it by the way. I read Michael's post and said "huh?" and hopped on search to look it up. It was tried as a replacement for Cermak by Rodney down in South Africa when he could no longer get Cermak locally.

Impressive results, Michael! It's always good to have extra arrows in your quiver, thanks for sharing!

If memory serves, it wasn't Rodney who tried it first but some other gent... I don't recall his name, but I don't believe he has posted for quite a while (or posts very much). I'll see if I can dig up the original thread on it.

Ah, here's the post I was thinking of...

Though a couple more exist discussing other, similar methods with different (cheaper than CerMark) marking compounds.

Very cool, thanks for sharing!
