The Talking Machine Forum — For All Antique Phonographs & Recordings

A recommendation...if I may. I always take good pics with my digital camera while taking apart an item. That way, I have something to reference in the event.

Yes, I know I should take pictures, but as this is nearly identical to the BF I have, I didn't think I could have any problems...

Maybe there is a small burr on the shaft preventing the shaft from protruding all the way through he casting.

Thanks for all the help suggestions. While at the workbench going through the mechanism once again, and comparing it to my BF, I noticed that the small mandrel shaft gear has a small step on it's surface. Upon trying it, the step does indeed fit into the mandrel shaft bearing hole, so it can contact the step on the mandrel. The large gear then goes on the side of the gear close to the pulley. I never considered orienting the parts like this, since in my BF, it's the opposite way, and since the BF is just a 2" longer version of the BE, I never thought that such a small part would have been manufactured differently. Again, if I had taken dissasembly pics like Wayne suggested, this problem would have been avoided.

Such a simple solution, I don't know how I overlooked it. I don't know why, but I've never had a problem with Edison machines, but these Columbia ones are causing me more problems. Thanks again for the help.

Is there a washer on the other side of the casting (i.e. against the next shoulder on the shaft)? If so, what thickness?

Bill, if your meaning the side of the casting opposite the gear, no there isn't.

If I had read this a little while ago, I would not have spent the time and aggravation of disassembling the pulley arrangement on my BF to figure out the problem.

Glad you've solved it on your own!

Bill, I really do appreciate your taking the time to dissasemble your BF. This really is a great forum!
