yes, it is time for another micarta/garolite thread.

I have a micarta ring 2.75" in diameter that is 3/8" thick and wide. I want the alphabet around the outer edge. Can micarta be machined smooth enough to allow writing? Writing is my last choice... is it engravable? Or am I better served with an adhesive label?

Ideas?

Assuming laminated, you can definitely polish the perif. but you will always be looking at some kind of uneven grain.

Engraving and filling with a solid color will be very readable.

Setting on a thin wall tube is a possibility.

Wrapping with a label is a possibility, and a decent printer will do a fine job with text at almost any angle.

Evan used mylar strips I think, as cover over a paper strip.

I've had excellent results with sealing the 'end grain' of micarta using low viscosity epoxies. If the micarta is warmed up quite a bit before the epoxy is applied, then allowed to cool as the epoxy cures, bubbles won't form and the epoxy seems to be drawn into the micarta.

I know micarta is supposed to be 'solid' but it worked for me.

I'd say it's solid if the resin permeates entirely the substrate material.

Now, how well does micarta take a thread?
