Also not shown, I replaced all of the bearings in the spindle with higher quality sealed bearings and rebuilt it all with new grease. Will spin much smoother. I also turned the stock pullies down a bit on the lathe before I disassembled it, which will help with balance. Once the CNC is dialed in I will probably just CNC new aluminum ones for even smoother operation.

CNC Build/Conversion Part I

By | CNC, Fabrication, Other Projects | No Comments

I bought this 3 in 1 a few years ago on sale from Grizzly, $1500 iirc, and taught myself the basics of machining and turning. Since then read a lot of books on the subject and lurked here a fair bit.

My background is on the 3D/CAD side of things. I started working in AutoCAD and Rhino (when it was just a free beta), and moved onto media graphics and have done that professionally for a long time now.

Suffice it to say, the digital side is my strong point, machine side, have plenty of learning to do.

To start, I needed to get a better adjustment on the saddle gibs so I made some new stainless bolts with nubs on the end. These seem to work really well as they are a much tighter fit than the stock ones, and much easier to adjust with the larger allen key.
