I'm looking to make a jig. It will consist of two phenolic rails about 24" long, and a router will run on top of these rails. I want it to be rigid and not flex under the weight of a router. My question is:
1) how thick to make the rails so that I won't get significant flex (the prototype currently uses a lamination of mahogany and wenge about 1 1/4" thick, and that seems fine)
2) where do I get the sheet?
Thanks for any help.
