Check your Inbox for a PM with my email address. When downloading the pictures, they are very low resolution and pixilate badly after 1.5x magnification. You'll need to email them directly to me. THe basic quality is good. If possible just re-do them with the lens dead in-line with the axis of the bore so you cannot see any of the sides of the bore in the photo. BTW: I'm having a memorial day observation with family and friends today so, I won't be able to do much with this until later this evening.
Thanks... BTW, this is not some wild goose-chase. I've done this before. In days gone by, the techniques I'm using were done with optical comparators / magnifiers and calibrated circular cut-outs. Nowadays, we have the advantage of digital cameras.I understand. Im in no hurry. I appreciate your time and willingness to try to help
You may have a gear not quite round when running , something may not have been set up to a tight tolerances. It might need rebushing and bored out . Not just drilled and or reamed to size.Here is a pic of the finished gears. Lathe is back together and everything is working...sort of. Im going to pull the gear box back off and check some things. Seems to be a tight spot and you can hear and see it slow down then speed back up. Not sure if I bent one of the shafts that the gears ride on just slightly or what.
