Yeh, there's all that too, but he did say top use the glass laid on top of the (wooden) playfield, which would still use the screws - see my response above, regarding playfield-wood/thickness/screws etc....

Aha! . . . I didn't read Swinks' article properly (sorry).
It still strikes me as a huge undertaking, but if you have any success that would be terrific.
I recently worked on a GnR playfield which had been cleared with two-pack CERAMIC. The finish looked like a sheet of glass and should very durable.
Let us know if you make any headway.
