Ready Steady Eddy

Compound brackets for ball screw FK12 / FF12 type bearings, this is how I made them.
Clamp all parts of bracket together, position bearing block on brackets and clamp, drill 4 mounting holes in brackets using bearing block as a guide, disassemble bracket pieces and drill largest feasible hole in each piece, in my case about 19mm using a cone cutter (it's hard work and hardly cuts), bolt bearing block to a bracket piece with some spacers between, mount in lathe chuck, use boring bar to open hole out to final size, repeat for other bracket pieces.



Ball screw mounted to gantry, it was on and off so many times it could have put itself together in the end, this was due to adding shims here and there to get it working smoothly. I was forced to sup a can of Guinness to use the cut up tin for shims.
