I have a Meisselbach spring drum and when I wind it, it feels like it strips/slips. I removed the drum and separated but don't see anything wrong. Any ideas? Thanks.

generally spring powered phonograph and gramophone motors will slip while winding or running if either end of the spring has become broken or become detached. If the motor bumps and thumps while winding or running, then the problem is dried grease or a lack of grease in the spring barrel.
(I'm assuming your talking about a phonograph/gramophone motor and not a fishing reel.)

Thanks. Yep, it's a phonograph motor. I will reinspect the spring and apply new grease. The grease was old. The barrel has two parts, the main spring on one half and the other half is enclosed. What does the enclosed half do? Does this need to be disassembled? Thanks.

The other half probably contains another spring this could be a 2 spring motor for extended play records, if you do the one do the other, or in some models the other part can hold the cranking ratchet pawls if its a spring care needs to be taken in which way its facing in the barrel, what brand of phonograph is it

Yes it is a two spring motor Heineman phonographs used them They had two types the horizontal which was the heineman one Number 77 or the number 16 which was the Meisselbach onesThey have two springs there has to be a pop off cover or its held in by a pin and a washer on nthe arbor shaft it looks hermetically seale but its not the cover should pop off when removing the pin or nut that holds it on be careful though when removing the cover or you can be in for a spring releasing surprise where protective face and eye equipment it can be lethal

Yep, it's a Meisselbach, motor number 12A off of a Victor Talking Machine. I see now that each side of the drum contains a spring with a washer in between. Both springs look fine. I cleaned both sides and greased. The drum still slips.

Does this motor have ramps on th arbour ( the shaft were the spring sits ) do they look pitted or worn down a picture would be nice check to see if the spring has even the slightest kink in it on the barrel side or the arbour side if that is the case that is what might cause the slip also if you have to much side or end play in the shaft the bushings could be worn check for that too too much play can cause the arbour ramp to slip off the spring greasing may not aleaviate the problem, You will eventually figure it out. If you can send some pictures with the shaft and the spring assembly exposed

P.S elongated holes on the springs on the arbour side or on the barrel side where the spring clips on to can cause slippage

This didnt cross my mind at the time but the problem may not be visual but if one spring is weaker than the other, the stonger will override the weaker causing spring to slip if thats the case replace them as a set some poly spring models (poly meaning more than one spring) have that problem
