Hi, i've been researching my machine. Its gonna have a large work area, 8'x4'. I've been reading the legendary MadVac build. He talks about a sandwiched approach to connecting metal to metal using epoxy and metal powder. I have two questions:
1. Does anybody have any links to a tutorial that shows how to do this
2. How do you make the sections for generally connecting beams together?
3. What's the best way to get them all square.
4. I'm going the cncrouterparts.com system of linear rails. How would I make a perfectly straight and level pathway for my 1/4" cold rolled steel for the tracks using this method?
