OK, I took the first step and bought the brackets for the gantry off ebay....

I plan on building a gantry that can handle 24x36, ultimately plasma, some testing with a router, maybe a drag cutter, and probably testing the whole rig out with some sort of crude plotter.

Basic Design:
Square Tube Skate Bearing Design, Rack and Pinion Driven XY and Screw Driven Z axis

Pre-made Gantry Bracket Kit
6008 Bearings/Hardware Etc
14-1/2 Degree Pressure Angle Gear Rack, 24 Pitch, 12 Tooth Pinion
Gecko G540/270oz motors, 48v 7.3 Power Supply
Mach3

I almost bought a TB6550 clone kit off ebay, the price makes it sound so attractive, but even if I get it working correctly, with only a 24 volt power supply, the performance wouldn't be that good, and the support of the G540 Mach3 can't be matched...
