It's been nuts around here lately...
This one for the QCTP.
Turned the outer and inner diameter for the hex then set it up in the mill for indexing.
I didn't show how I set this up for the previous job; I have a limited selection pf parrallels so I put 2 of them under the dividing head so the work cleared the base of the mill vise, then used a jack to maintain the height between cuts.
Tighten vise, cut, loosen vise, rotate, tighten vise, check level (my chinese vise has an annoying amount of lift), cut, etc.
I took it back to the lathe this time before cutting off the nut from the stock, much easier to do the chamfering, also used a form tool to radius the top
Over to the bandsaw, then back to the lathe to face the bottom, drill, bore and thread. Had to do the threading on the lathe as I only have a starter tap in this size, no intermediate or bottoming ones. Forgot to take pics of the threading in progress but I'm sure they won't be missed.
I'm reasonably confident I won't hurt myself on this one.
Although this photo shows it does still need a little deburring before the heat treat.
Heat treating won't be happening until I've finished all the arbor spacers.
I'm thinking of making these nuts to sell. If I can get around $750.00 each for them, it should be a viable business plan...
