Hi all and Merry Christmas
Not much has happened since last, but I got the support ends of my four ball screws turned down. I also made the fixed end for my Z-axis ball screw and the BK12 fixed bearing slides neadly on, so that's good.
When I tried to thread the shaft (M12x1) for the lock nut with a die, I wasn't able to do so. The die wouldn't bite into the material and I guess it's because it's too hard? Threading soft steel was no problem.
Some ideas:
I could try to anneal the metal where to thread, but this may ruin the straightness of the shaft and the tolerances for the fixed bearing.
I could make the thread by turning it, but right now I don't have the proper toolholder. Maybe I can borrow one next year.
Do you guys have any tricks that might work?
Regards Brian
