Eventually I got a 2' x 4' piece.
But not before ordering another one from somewhere else, so soon I'll
have two.
Oh well, I'll use both eventually.
What I need to do is transfer a pattern to the acetal for engraving it
by hand, using a dremel router with a 1/16" mill bit. CNC engraving is
not financially practical here--and for the patterns I need, a stencil
will not work.
I had assumed on getting full-size pieces of adhesive paper, inkjet
printing the patters on them and sticking them on. Cutting right through
them, then peeling off the pieces. Is there a better way? My concern
here is that the adhesive paper might stick too well to the acetal.
I know that heating adhesive-back labels with a heat gun helps them peel
off easily, but the acetal is thermoplastic itself. There's also
solvents that weaken the glue, but they also might harm the acetal.
VM&P Naptha (available from paint stores) will remove the self-stick
adhesive without affecting the acetal.
