Question
Rodger:
  I have two questions about my mid 20s Mills Operator Bell machine.
  1. What type of grease and oil should I use when I re-assemble my machine after de-greasing
  2. The holed payout disc connected to the middle reel spindle is loose, and can be rotated about 5 degrees when holding the spindle stationary. Is this normal or should I peen the locating pin to tighten the fit
   
  Thank you

Answer
Hi Larry,

As for grease and oil, the oil I like is made by Blue lake products, in a package called a Zoom Spout, it contains highest quality finest all-purpose turbine oil in a 4 oz plastic bottle with a long spout you pull out to reach those deep areas and is able to place just a drop or two there, great stuff, and it doesn't smell or stink like 3 and one oil does. For grease I like a synthetic multi-purpose, heavy duty grease called Super Lube made by Stmco Chemical corporation. It's a clear grease much like Vaseline in texture but much better.


As for your reel index disk (with the round holes), it needs to be stationary, not loose! So you need to re'rivet it, or reset the rivets so the disk does not move on the brass axel disk mount. But if your reel bundle is still all together and it is the reel that is loose and not the actual rivets holding the disk, you will see two nuts between the reels on the axel housing that you can tighten and this will tighten the reel to the Axel. It could be one or the other causing you this loose reel problem. If you hold all the reels tight so they cant turn and this disk is still real loose and sloppy, then it might be the disk rivets have got loose and need reseting or replaced. If the disk is tight on it's brass axel housing, then it the two bolts you will find down between the reels on the axel, and each reel has these, that need to be tighten.

I hope this helps you get it all fixed up.

Thank You
