no it is acrilic I wish lexan was as easy to find :)

not super strong but I had to start building it was a scrap I grabbed
while I was at the plastics shop
I was at the welling shopp looks like I may have some scrap aluminum for this piece next week and I have my 1" round bar and my 1" angle for my x and y

but I scored thoose rails and wanted to see how sturdy they would be with something mounted up

here is the pic that shows the threads
there a a bigger on that show it better on the site in the first post

well I burnished the edges just for the sake of making look perty :) until it gets used the first time

Acrylic eh? I take it you will be cutting balsa or light ply with your machine. I guess it will suffice for that, but if you crash the router into a fixture, then you could have a loaded router jumping around the bench, spinning at 30000rpm. I am not trying to put you off, but please be aware of the dangers if the acrylic should snap. Keep postin' them pictures though:D

I know the dangers and I plan on replacing it with something more sturdy
down the road I just happen to have a piece of acrilic the right size just needed holes drilled

so my new parts availabillity has thrown me back in to the design phaze
and when I get these next 2 machine done at work they I willl have a couple of Minutes to think about it

but the z axis is going to grow some what useing some left over thompson
berrings that we are no longer using and I plan on using a THK knock off type bearing made by INA and maybe even some real nice ball screws
