Thanks,
I'll try to keep this one as simple to make as I can, but there will be some machining involved. Bearing mounts and a few parts of the Z axis mostly. The bolt heads could have been shortened on a disk sander instead of the lathe. The frame didn't really need welded joints. It may even be possible to use the bearing blocks and NEMA23 plates from Ahren's site if no lathe and mill is available. As I add my version of the parts to the drawing I'll try to also show an alternative method of doing the same thing without machining. Ahren has dimensioned drawings for these parts on his web site, so I may just try to design the machine with those parts in mind. Once I have the basic frame and rails assembled, It will become easier for me to figure out how to do this.
