Bits and Pieces

Ran into some problems with the corner blocks for the XY frames. Each of the blocks has 3 trapped nuts. I did the same thing as before: drill with undersized bit and self-tap with grub screw. It just now occurred to me that I could use an M5 screw to do this instead of a grub screw. I overtightened one of the grub screws and cracked a block. Superglued it back together. Fingers crossed. Need to drill out the vertical holes in the blocks. I'll have to dust off the drill press. Hoping a 5/16" bit will do.

Also noticed that the diagonal tie brackets don't have trapped nuts. Not sure how I'm going to attach those to the frame. I'll have to improvise.
