Thread: Quad speedo glass - repair how?

Yeh I see what you meen @Gibo, I have the same unit in my workshop in good order but to get past that outer ring is going to be a bitch.

If it was me I would just make a cut with the angle grinder fitted with the finest cutting wheel and just pop that outer ring off with screw driver easy as.
Get the glass cutter to cut circle glass to size,, replace then refit outer ring and wrap up with insulation tape.
Not perfect I know, but tidy enough and sealed from the elements, and better than throwing away.
