Default Re: Any ideas how to mend glass tuner scale?

I am finding this an interesting thread. Could one take 2 very thin pieces of glass and decal the back of the one piece to use as the front, then sandwich the 2 together, with the decal/lettering in between?

They sell carbide glass drilling blades here locally in a selection of a variety of sizes in one package at Harbor Freight Tools I saw them yesterday.

I think I remember reading in a very old copy of QST (1930's?) Hints & Kinks you could drill glass with a metal rod and very fine grit using kerosene of camphor as a lubricant. The rod needed to be the same size as the hole you need, and very light pressure and a lot of lube was used. IIRC, the pix was of it being done with a drill press. A lengthy process I suspect, with a lot of finesse needed.
