Hello Wayne,
Thanks for that tip.
The company making the screen does not think it'll be a problem supplying them an undersized lens, they'll have to make it up to original size before casting the mould. If I haven't got any further in the next few weeks I'll speak to them again when I collect the fairing screen for my OCR 1000.
Kind regards, Joe.

Sorry for taking so long to reply. The glass was 1/8" thick. I made a fixture for the cluster plastic and ran it in the CNC mill. I used the program to generate a drawing for the glass cutter to make an exact fit that was installed with glue on the edge to hold in place without seeing it.

Hi Jim,
Thanks. I have a surround that was machined out by a friend who no longer rides. It takes a piece of perspex that is around 4.5 mm thick (a little over 1/6th Inch). I had a piece of glass very accurately cut to size and it drops in and is flush with the top of the surround. Trouble is, when I then put it on the instruments, the needles touch the inside of the glass (they are slightly curved up with age).
I tried packing the join between the surround and the metal instrument case with a thin frame but you can only get away with so much before it interferes with the overall fit in the tin can (specifically, the flip top starts to jam on the top half of the can if I have enough packing in to get the glass to clear the needles).
So I figured if you only machined down, say 1/8" and then fitted, as you have, a 1/8th inch glass, that would buy me 1.5 mm extra clearance between the needles and the inside face of the glass. Maybe enough to get away with it.
I'll reply to your PM.

Wayne,
I think you mean 4.5mm is 3/16". The ones I made are 1/8" (3.18mm) deep and do not touch the needles. I like the glass for durability when cleaning, harder to scratch when cleaning. You do not have the curve, but no fix is perfect.

Hi Jeff, I did mean a little thicker than 1/6th of an inch (I was too lazy to do an exact conversion), the main point being that I knew it was thicker than yours and recessed deeper. I think yours would work well. As mentioned, yours is around 1.5 mm thinner (which will be extra space above the needles so to speak) so should give me the clearance.
Sam's conversions were to glass and I have it done on one set of instruments. Much better than perspex and what the factory originally wanted.
