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
