Edison Home D - Source of replacement bearing?

[Sidewinder]

Hello,

Does anyone know where I can source a new bearing for my freshly aquired Home D. The old one seems to have expanded through non-use. What is the best way to remove the old one! many thanks

This link should help with removal http://forum.talkingmachine.info/viewto ... =7&t=17596 as for the new bearing I'm sure Ron Sitko has the part but I'm not sure.

Thanks very much!

I really hate the idea of tapping out the swollen bearing from the iron casting -- the casting is brittle and the upright stanchion that holds the bushing could break off! I devised a much better way, as I described on a previous thread several years ago. The concept is similar to a gear puller:

The biggest problem is freeing the mandrel shaft from the bushing and then removing the swollen bushing without damaging the machine. The bedplate is cast iron, and the metal upright that holds the bushing could snap off if you are too forceful with it. On the one occasion that I had to replace one, I used a penetrating solvent to loosen up the mandrel shaft and then gradually twisted and wiggled it free without too much force. I did not want to risk damaging the metal or paint by trying to drill or cut the bushing out, so I devised a very simple solution to squeeze it out without any stress to the casting: I found a piece of water pipe whose interior dimension was large enough to slip over the bushing. I cut a piece of that pipe, perhaps an inch long and trued up the ends on a lathe. Then I found a long machine screw that would fit through the hole of the bushing, and a nut. I also found two washers that fit the machine screw, one large enough to butt against the end of the pipe, and one smaller than the diameter of the bushing. I slipped the pipe over the bushing to butt up against the upright holding the bushing. I put the small washer on the bolt and passed the bolt through the bushing until the bolt head with small washer was against the bushing. The bolt was long enough to project beyond the pipe that shrouded the bushing. I slipped on the large washer, then the nut. All I had to do was turn the nut until it pulled the bushing clean through the upright and into the pipe. Nothing could have been simpler or less forceful.

Bronze bearings are available as replacements for the pot metal and are fine for most people, but I went a different route. I tried a Timken needle bearing (http://www.timken.com) for minimum friction. I found a bearing with the correct I.D., but had to machine a metal adapter sleeve to make the O.D. fit the Edison. I simply press fit the bearing into the adapter sleeve. I packed the bearing with LubriPlate, a white lithium grease. My experiment was worthwhile, it extended the playing time per winding.
