Something like this? See attached picture. Turned out from brass these days, counterweight mass center shifted down approx. 10 mm relative hole axis. Not so much as I want, but 1200 tonearm doesn't give many opportunities to improve. Listening now.
(Sorry for small offtopic).

I read the entire thread after a looong time. Very interesting.
I was wondering if it would make sense to attach the chunky thrust plate sandwich on the turntable's body instead.
Some of us are already coupling it to the big mass of the body with wax or bluetac with very nice results.
This could reduce the work required on the lathe and would eliminate the need to modify stock bearings. We would just remove the stock thrust plate, and attach the new one to the well of the body.
I understand that there could be issues with the plate's angle, but we can test this before rejecting it. The well's bottom could be molded perpendicularly enough to the screw base.
The other negative would be that this way there will be no way to have an oil "bath" on the shaft. But this can be overcome by frequent cleaning and lubricating with thick oil. Something that is a good idea anyway.
On a different subject, another idea could be a chunky meetal ring fitted and screwed tightly on top and around the stock bearing body, to increase its mass, rigidity and coupling with the turntables body.
I am no engineer so feel free to call me names for my ignorance
I have been reading up on the feedback on the forum re contact between the bearing and baseplate.
There are a variety of ways it can be achieved and I have a few ideas I want to try as soon as I have finished the batch of bearings I promised.
I dont like driving blind as it were and want to measure electronically the differences gained or lost by the various options so it will take a little time.
As ever if any additional tweaks surface they will be DIY or made at LOW cost.
Any new feedback on anyone's experiences would be welcome for the benefit of us all.

Cool
About lubrication, I had very nice results with BP vanelus. It is a monograde oil (Like the factory Anderol 465 - SAE 30 / ISO 68).
The only drawback is that it comes in 4L cans, but it is rather cheap.
I also tried the thin oil by singer, but I prefer the thicker one. It stays in place longer and the turntable runs more freely and for longer periods without relubrication.

Anyone tried these thrust pads? I was thinking of either trimming so it’s round and attaching it between the end cap and actual bearing chamber or just screwing it in to the original holes in the bearing shaft . http://https://www.ebay.co.uk/itm/30...mis&media=COPY
Also I’ve pm’d you Gerry (diviy)
