Thanks to all that replied. The size of the socket turned out to be 2". I had a 3/4" drive socket in that size. I installed a 5/8 bolt through the hole wrapped in electrical tape to fill the hole so it would be centered. Ran a nut down to secure everything nice and tight. I chucked in a drill press on slow speed and filed the OD to fit. Took an hour of time but the nut came off. Would love to have a lathe!
