Hey all,
I was farting around at the shop yesterday and decided to put an indicator on my old Cinci drill press to measure the runout and - Yowsa - About 0.010"!
At this point, I have done very little to the machine other than give it a much needed oiling, relocate the motor, mount a vise, carefully clean-up the taper with a finish reamer, and repair an add-on light that was installed by a PO.
I am confident the runout has nothing to do with my clean-up of the taper as I measured the same wobble on the inside of the taper and outside of the drill shaft, and only made a few turns by hand with the reamer to take the tops off of any ridges or burrs that were present before I started seating any tapers. The reamer came out of the taper with only the slightest amount of tiny particulates.
Anybody have any idea how to adjust the main shaft bearings on one of these? Before I contemplate any major surgery, I want to see where I'm really at with everything properly cleaned and serviced.
Unfortunately, the machine didn't come with a manual or serial number data plate, and there is no applicable reprint posted on Vintage Machinery. I've dated the machine approximately by design.
Thanks in advance!
