Randall,
Very elegant work! A question and a thought:
-consider using a used surveyor's tribrach for your leveling base. They are usu available on eBay for under $50 and will give you very precise control over the leveling screws. Then you can attach your plate/mirror to an adaptor that locks into the tribrach (seco -www.surveying.com makes one, but they can be had for less on eBay). I did this with some schott black glass and was pretty happy with the result, but you will def need bubble levels that rest atop the glass directly.
-- and a question. Where are you getting the front-silvered glass? I've hunted around and can't find any that doesn't cost a fortune!
best
