My Commonwealth does not go slow anymore!!!!

[cafe latte]

I just put my strobe disc on it, all I have done is bend the idler bracket straght a couple of weeks ago, but it was still slow after, but a bit better. I wonder if the bearings have settled down as they are new, but tonight when I tested it it was rock steady and the count test was spot on!! .I dont like things fixing themselves, but this has been driving me crazy. Maybe the idler needed to deposit a bit of rubber, maybe it is bearings freeing up? All I know it is speed perfect which will do me!!!!!!
Going to put another record on Any requests ?
Thanks

Great news! Just play whatever comes off the stack first!

Hi CL,

Good news I guess. Enjoy it while it is working right and hope for the best. I never like things to "fix" themselves. I worry that the problem will come back.

That's good news, by the way. Saw some massive ex broadcast decks at the local brocante on the weekend. You'd need on helluva big lounge room to fit them in, not to mention massive wads of cash to buy them. You've done well, I think.

Hi Phil,
fixing the bent idler wheel arm did improve things a lot, but it was still slow. I also noted that the motor was not sitting straght on the rubbers, so I packed with rubber washers as IMO the rubber mounts had gone a bit soft. With the motor square and the idler square the speed was only slightly slow, so as an experiment I tried putting a soft rubber belt round the idler wheel as a tyre to see if it helped, but the TT ran much slower so I removed the tyre. I cant help thinking that maybe the idler has suffered a bit of creep, but with use somehow this has stopped

Hi CL,

It could be that you are closing in on it. When the rest of my Rondine 2 arrives I expect I'll be learning about creep. My guess is that it should not be the problem in an idler drive machine that it is in a belt drive, however I would think it exists. From the equations someone posted on your other string smaller drive pulleys on the motor make it worse. I haven't seen the Rondine motor as yet but assuming a four pole motor and from the platter diameter the motor pulley is less than 1/4". I expect that by the time I get this machine running on speed I'll be a creep expert.
