When I built my CNC table a few years ago I built it with the idea of putting the 4th axis on the side.I am finally getting around to working on it some.The "lathe" can be moved up or down in and out to adjust for sizes up to 24" diameter.2 trailer jacks are used to raise and lower the lathe. The lathe is attachedto the table in away that it can slide up and down.The 4th axis can also be turned vertical if needed. I need to install themotor/pulleys and covers. I will probably paint it to match the table.The bed is made from 2x6 tubing with 1/2x2 1/2 cold rolled bar stock for the "ways"I have to finish putting the motor and pulleys together yet.Jeff T.
