The maintenance man brought in a 5/8" cross shaft out of one of the molding presses today.
He asked if I could turn the OD down to fit a 1/2" rod end bearing.
Of course I can.
I just got it set up in the lathe and he comes back in saying he wasn't sure he wanted to do that.
If the next cylinder replacement takes the 5/8" shaft we're in trouble.
I suggested making a new 1/2" shaft and keeping the original. He liked that idea better.
While I was making the shaft he came back in asking if I could make shaft collars to locate the
rod end bearing on the cross shaft.
Sure can.
I chucked a piece of 1" 1018 and drilled a 1/2" hole about 1-1/2" deep.
Then it turned fun! I needed to part the collars off 1/2" wide.
It was the very first time I got to try that parting tool holder that came with the PhaseII QCTP.
I started out a bit too tentative at 90RPM. The blade would grab occasionally. Then I raised the
holder up about half a turn on the adjusting disk and jumped it up to 240RPM.
It went through that 1018 steel like it was machinable wax. A couple tapped holes
for set screws and it all done.
45 minutes after the request, the machine was up and running.
I love it when a plan comes together.
Even if the plan is coming together as the machining is being done.
