Interesting. That design sounds like it would be best suited for a skateboard bearing clamped setup for the cornersor a v rail setup. I guess I could get that to work for me if I were to put the gantry rails on the top and bottom versus the setup I have with them both on the front. That would certainly give me more strength for those plunges but it would eat up some of my Z height.

Hmm. I guess that steel enforced wood approach would only be financially viable if I can get a good price on steel around here. I will keep my eyes out.

I have always wanted to use 80/20 Extrusion for one of my projects but unfortunately that stuff costs an arm and a leg to get. It isn't too expensive but shipping to Central CA is ridiculous.
