RC - I didn't go back to your other posts to look.
but, what will you be needing the clear plate for the most ?
after you have had a router(s) for awhile, you sort of accumulate
a box full of different plates for different applications.
are you free-hand routing signs and templates ?
(exactly like Roxanne said)
that last plate I made a few weeks ago, I needed a very tight opening
for the bit to free-hand rout some knife handles.
I made the hole a little small and "very slowly" raised the bit up through
the hole to cut it that size. stopped the router, removed the plate,
and made the hole slightly larger with a hand file and round sanding block.
it just takes a little imagination and extreme caution to do it his way.
(I used frosted plexi because that is what I had on hand)

but I do have some plates made out of 1/4" plexi (Lexan) just the same.
