Any idea why this lathe is chattering? Spindle bearings?

Surely best to remove the spindle and fix it properly.

You're right it isn't ideal but the bearings have already been run loose and had an awful shock from recent tightening up. I guess the answer is to install the new bearings and make sure they aren't such a tight fit so they adjust properly.

Bearings are tougher than you think in this case they may be K already , think of the pounding they take on a car / truck etc.
I think it's on the SKF site but may be Barden but they demonstrate fitting AC spindle bearings the a nylon tool and a hammer , yes it only put force on the inner or outer race as needed not both.
In this case the as I posted the spindle should be attended to , but I fear the OP will now have the devil of a job getting it off

When we had a bad bearing let's say about a 10 inch shaft with it stuck in the cartridge housing ( big electric motors ) we fetched in one of the boiler makers , now I have never seen this done since I left the firm , but he used a normal welding torch not a cutter and manually manipulated the oxy to cut .
He could take of the inner raceway and leave the shaft in marked.
Now these we had to fit using go no gauges and heat to get them on
Those were the days

Ps found the fitting guide from SKF with hammer
