I have been a lurker here for a month or so now and I am planning to start a build after Christmas, I give all my spare money to the grandkids at christmas time. Anyway I noticed over at www.buildyourcnc.com there is a pic of Octavio's Metal CNC Machine that I found interesting. I thought I would bring it up about the way he used the same bolt for both the Z axis and Y axis bearings. I have drawn a Sketchup of something that I would like everyone to digest. Perhaps it could be a mod for the 4x4 hybrid or something.
