First Build 5 x 12 Steel Frame CNC router

What kind of bearings, if that is how you are pivoting the A-axis? Got any detailed view of it?

Nice work so far.

Thanks for the comments

Heres a view of the bottom of the Z axis and a section cut into it.

Here is the box tubing removed

The bearings are roller bearings that I can get from McMaster Carr easily. 1 1/4 diameter shaft. Bearings are designed to be held into aluminum housings bolted into the 3 x6 steel tubing. The shaft is a 6 inch threaded on both ends. Again something I can just order from McMaster. The bolts into the shaft allow me to put preload into the bearings. I was thinking of bolting the pulley hub (pulley is not pictured) to the spindle mount.

Open to thoughts on this design. I think it will work....
