Mini Update on the sloooow Logan effort:
I found a local shop to burn the broken "easy out" from my flat belt cone. They did a beautiful job at a very reasonable price. They "upsized" to a 5/16 thread, and salvaged the part.
Per mrbreezeet1's idea, I used an air chisel to break loose the capture nut on the spindle bearing. Three or four hits and it was off. Thanks mrbreezeet1, for the help. Holding the bull gear tight in a vise was part of the problem. I ended up using 0.093 inch, 6x6 lead sheet from an industrial supplier to make a decent set of soft jaw covers. The 0.093 inch material cut easy with a chisel and was easy to shape, in case anyone else has to do this.
Also, I got lucky on a Craigslist deal. I was still hunting for an inexpensive spindle that I could use, and needed to replace some carriage parts. A fellow up in Trenton NJ had a partial model 210 headstock and a carriage for sale. The headstock looked a little rough, but the spindle came out easy and looks usable. The carriage was not from the same machine, and appears to be in excellent condition - almost no play, not even any dirty grease. It's so nice, I think I'll swap most of the parts onto my nasty old saddle, and save the good saddle in case I ever get the bed cleaned up. It's just too nice to bugger up. It was a 4 hour drive, but it worked out well.
Can anyone please provide guidance on bearing repacking? The main spindle bearing is sealed on one side, and I didn't know if the cover can be removed and replaced? If not, can a bearing be properly hand packed from one side? I was trying to get the bearing off the spindle, but I'll need to have some sort of tool made up to push against the inner edge of the bearing. There isn't much exposed past the shoulder on the spindle nose, so I'm concerned about damaging the bearing. Since the spindle is out, I was thinking of just soaking the whole end of the spindle and repacking the bearing by hand with the bearing in place (?). Any thoughts/guidance?
Thanks in advance, TomKro
