Re: My HMV 109
We've both got exactly the same 'model 32' motor. Mine is fitted with 15ft springs, but some were fitted with 17ft springs and would probably manage 4 record sides - the springs are in series. It'll say on the barrel if you look closely - there'll be a little number 15 or 17 stamped on it, but you'll need to look closely to see it.
Are you absolutely sure that your governor is working correctly? From stationary with the speed control set in the middle 78 RPM position there should be a gap between the disc on the governor and the felt or leather pad. When the motor starts, the three balls will spin out and pull the disc along the inner shaft until it touches the brake pad and that's how it maintains its exact speed. |

Re: My HMV 109
Ok, slowly figuring things out. I wind around eight to ten times then get resistance. That is when I stop for fear of hearing a ZINNNNG! Winding on feels like something slipping and I can wind up to 28 times more until it won´t wind any further.
I have now played one whole record, A and B side and it still had enough puff to run for a few minutes more. Having said that, I have these needles that are supposed to run for 10 sides, how do I know when a needle is past it? By the way, did I mention that I love my "gram?" |

Re: My HMV 109
Lets start again! Let the motor run right down, until the turntable stops under it's own steam. Now start winding. There should be no sound of "slipping", which would indicate a broken spring, so you should be able to wind about 30 turns before you begin to feel resistance. If you are getting resistance after eight to ten times, then there is something definitely wrong!
Needles that are "supposed" to play ten sides rarely do, and if they did, they would be so hard they would damage your records. "Ten sides per needle" is a bit bit of sales patter by the manufacturers. Discard them, and get the ordinary ones that are discarded after one side, or two if the record is not one of your favourites! |
