Steve,
I am going to use 3/4 maple ply. It is the same wood we use for steel rule cutting dies. It has to be better than MDF. I thought about reinforcing the gantry walls with fiberglass. I don't know if it would help or not. I am mainly using maple because my die maker has it on hand and can burn it on the laser in about 10 minutes max. I am going to use Hack's design verbatim, I don't feel like reinventing the wheel right now. Thanks |
