to read everyone's comments and tips, thanks. I have way too much of a tear into and rebuild stuff kind of mentality to be happy with anything that doesn't have some levels of DIY. plus the funky aesthetics of the rok's are right up my alleymy next move is to build a plinth. I think I'll go the turn the table sideways with a CLD route unless someone talks me out of it. I've got plenty of hardwood kicking around for armboards. and i orderd some Si3N4 balls too.
then I guess I should think about taking on trying to machine that bearing. Can't do that one myself but there still are a few genuine machine shops in my pseudo-industrial neighborhood here (erstwhile manufacturing zone run amok in hi-tech)I'll post an update later on as things proceed...
regards,

Don't make an completely non reversable changes at first.The only machining I have had to do is to remove the wear pattern on the thrust surface. Everything else was simply micro polishing to get things straight and smooth.
If you have any touble just ship the platter to me and I will do it for you. I have micropolished 3 of the 5 Rek O Kuts and will be doing the other two shortly.
thank you for your kind offer, i may take you up on that. The bearing on my GH platter looks very clean, but the bearing on the platter from the b12H has a small center dimple where it makes contact with the ball. I see you had that problem too with one of your rok's.this week I'm trying to quiet down the idler wheels- the older table has a metal idler wheel, thats the table I currrently have the rega arm mounted on. sounds great though there is a barely perceptable 'whump whump' from a small indentation in the rubber; probably the wheel was parked against the motor spindle for a couple decades. honestly, I could live with it, you cannot hear it while music is playing, but would be nice to zap it. the GH table is a little bit noisier while it spins than the older b12H table. (the GH has the papst motor, the H has an ashland motor), some noise on the GH seems to come from what sounds like a whirring air rush from the motor flywheel, but the more offensive noise is from the spinning of the idler wheel itself. the idler wheel on the GH has a plastic core. I've got it soaking in simple green right now, but I guess the best thing to do is get both these wheels retreaded and see how they sound. maybe the rubber is just too old/hardended
I don't yet know what the GH table sounds like as I haven't mounted an arm and listened to it yet. My plan is to build out the better sounding of the two for lp's and use the other one for 78's. but just by running the B12H in its junky old stock rok plinth, already my td126 and rega tables are retired with no hesitation... I'm still surprised how completely different (and better to my ears) this arm/cartridge sounds on the rok compared to the rega table. its not a subtle difference.
I have bought 5 Rek O Kuts and the rubber is in different states on all five. The quietest one I owned I sold to a friend. It had very supple rubber tires and the isolation pieces were nicely pliable.This table just blew me away. Every album sounded so much better than I had ever heard it play before.
The one I am working on now has great isolation pieces and aweful tires....I will be playing this one for some fellow inmates this coming weekend. Hope they like it even if it is imperfect.
The sound on these tables is simply stunning when you get all the particulars worked out. Think 10k for a modern table and these Rek O Kuts might still play better music.
The prat and emotion of these tables is really incredible. Getting them quiet is cheap and easy.
Although I have not found new replacements for the isolation pieces. I will find some eventually.
