Only my second post, but have been lurking for quite awhile taking everything in. I started building from Joe's 2006 plans tonight.
First of all, many thanks to Phooddaniel, Joe, and everyone else for their time and effort. I followed along at www.buildyourcnc.com to get started, and I'm using that machine to make the parts for Joe's.
Glued up the Z axis tonight.
One question if anyone knows...looks like the plans call for black gas pipe on the x and y axis, but drill rod on the z. What's the reason for the drill rod? Would it be ok to use the 3/4 gas pipe on the z axis also?
