Interesting build. Great photos. Wish that I had a local metal source where I could get such prices.

I can guesstimate the dimensions of the part that you show by comparison to the size of the bearing or the sizes of other objects in the photo, but it would be helpful if you could mention the actual dimensions. Is the bearing block essentially the same as the stock size, minus facing to square it off?

Local metal supply rem piles are always best!

I machined to identical bearing blocks and will use the stock bolt holes for coplanar alignment. Waiting on my ballscrews though to verify alignment before i drill the bearing blocks for mounting holes. Here are some pics to show perspective better:

Width of bearing block:



I basically cut the blocks to size and then drilled through the block with a 1/2" drill to to provide a way to locate and bore the bearing hole on each side of the block and have them be coplanar.



Checking fitment:



gang machining to make them identical:



finished blocks with 2 bearings per side:
