Re: 3 x 5" wheels?
If you're dead set on 5" diameter wheels,VEX EDR (http://www.vexrobotics.com/vexedr/products/accessories/motion/edr-wheels.html) has some. Interfacing with Tetrix will require some creativity.

Re: HSM Express+Tormach undersized holes
I'm downloading HSM Express right now, but I'd suspect there might be something wrong with your cutter compensation settings. Either that or some setting to leave stock on walls.

Re: 971 CNC Router
Any chance of releasing the design notes or the CAD model? I'd particularly like to learn more about how you analyzed the different configurations and modified the design to get your desired rigidity.
