Might have a major problem

cleaned around the oilers and got rid of all of the dust, spayed with windex and wiped down. Removed the rear oiler and it is not good. If the oil goes straight to the bearings the whole lathe could be ruined in a few years, if there is wicks it would not be a problem.

Maybe fresh felts?

Here is their website https://www.aagearinc.com/about
when we were there they were making timing sprockets for Toyota racing, nylon idler gears for a doughnut filling machine, and were getting ready to make gears for a Boeing 767.

One of them gear drive aero planes?

Got the gear back along with the new plastic test piece! This one doesn’t have a key way since it will weaken the gear by a lot so we will find another way. There was 1/8 of an inch from the sides of the key way to the root of the gear! Along with porosity it was not going to last long.

any updates on this?

I'm considering the same lathe

bondo, lots of sanding but if you dont want it to look perfect they are great, I can hit 0.0001' tolorances easily and the tailstock can drill a 3'' deep hole which is way better than a southbend but cant thread, good for small to medium parts with good tolorances, kinda heavy at 1,500 lbs (680 kg) but very rigid and I would take it over a southbend for the parts that I make.

Optios on the Key.

One is cut a smaller key in the gear, example, if origami was 1/8 wide and tall, make it only 1/16 tall.

Take your standard key stock and mill it shorter or thinner.

Second option is using the lathe as a shaper/slotter, place gear in chuck and make a cutter that will cut the keyway and place in in your tool post aligned like a drill would be in the tail stock.

Now position it to where it will cut the keyway if the carriage is moved towards the chuck, like a shaper would.

Fix it so adjustment of cross slide effects the depth so you move carriage I and out of the gear then move 0.001 and repeat.

You add a carriage stop so you only cut where the gear is not.

You could do both, with broach cut keyway but only do first cut so it is shallow.

Then if you want more key in part of the gear make the part away from the gear full depth.

wrong thread

I am working on filing the tailstock smooth and bondo on the front and side of the lathe is done, 15% still needs bondo and 10% needs to be sanded
