Hi.

I am building an amp and will be using a clear plastic over the front
panel graphics.

I could use some help in choosing the material, such as Plexi or Lexan.
Since I will be drilling couple of 2" holes to mount panel meters, I need
some suggestions for which material is the best to work with. A hole saw
in Plexi is prone to crack and maybe there is a better choice. There also
may be a better method for creating the holes than a standard hole saw.
Suggestions???

Why not just use acetate sheet to cover the panel. Like what is used with
overhead projectors. If it is just to protect the graphics and not for
mechanical strength that is. Jtt.

or just put a good coat of clear lacquer over the front panel graphics

When I have needed to cut holes in plexi in the past, I always created a
plywood / plexiglass sandwich. Just place the plexiglas betewwn two thin
sheets of plywood and drill thru the whole thing with a hole saw.

On the other hand, you could just mount the plexiglass on top of the meters,
this would protect the meter faces from scratches also. This way, you only
need to drill holes for switches and knob shafts.
