After the numeros suggestions of differet types of oil for the bearing, I decieded to make a comparison with the oil I was using (quality gun oil)and Mobil 1 which I had as left over. The Mobil 1 was of coarce much stiffer. With the Mobil 1 my Scheu 4,5kg platter spun only for two minutes instead of five.As some of you know Scheu uses a very fine "fishing line" to rotate the platter. So with the stiffer Mobil 1 the speed needed some ajusting - but still the sound was, although with darker back ground and more prestine timbers, also somehow dull without dynamics. The gun oil presentation seemed more light footed with more dynamics.
But when I changed the original (very thin) rotating line to 0.25mm fishing line -what a difference! It was one of those rare moments when you go into extacy listening to the music and can't help but smile. =) There was more timber, blacker background, much more dynamics. The whole preasentation was so much more realistic and prestine that I was just amazed. Well, the next day the difference wasn't quite as startling but impesive all the same.
So this is what I've concluded: the thicker oil, though not as lubricant, dampens the small resonancies more thus giving the bonuses in timber, background etc. The thicker line gave the clearly better dynamics ja rythm.
These are my findings with the Scheu inverted bearing. Your experience may differ but the Mobil 1 and thicker line are definately keepers.
But of coarce I'll probably try some other oils still... ;)

My favorite, because it actually dropped the noise floor (on my TT anyway) is the van den Hul Spindle Oil. It's doped with zirconium oxide crystals (extremely hard!) which act like micro ball-bearings to keep the metal surfaces apart.I bought it on a lark after reading about it on the vdH website, but not really expecting to hear any difference. Guess what?!!

If the entire bearing is ceramic (the shaft and the bearing wall), I would not recommend it. If the shaft and housing are metal but use a teflon or ceramic thrust pad at the bottom (or top, if it's an inverted bearing,) that would be OK.

The shaft (inner bearing) and outer bearing wall is metal, the thrust pad at the top (it is inverted) is teflon, and the ball is ceramic. The instructions for the table tell me to place the oil in the upper oil bath of the inner bearing where the ceramic ball will sit and let it run over so it drips down along the bearing wall into the lower oil bath. Then the outer bearing slips over the inner bearing.Pictures are are in the link below, just scroll down the page.
Sounds like it would work. I also see VdH offers another oil, the TLF Type II which may work as well.

Yes, I think that would be fine. Ceramic is very very hard and will push the zirconium out of the way, while with teflon, the zirconium just imbeds in it (my Studietto has a teflon thrust pad.)It's just that some TT's employ a nylon or plastic outer bearing, and that might suffer unwanted wear.

I'm also looking at Tufoil and Marvel Air Tool Oil.

...and said, via e-mail, to use 40 weight motor oil. He said the lower number did not matter. This is an inverted bearing and the table has two motors. It also has a vent hole at the top of the bearing where the ball is, so the subplatter does not take forever to settle, which is nice. I use Mobil 1 as well, and it seems to work and sound fine.Steve
Hi Steve,Nice to hear that. If it's good for Kuzma, it's good for me. =) Also confirms what I'm hearing I suppose. My Mobil 1 is a little stiffer though, 5-50 weight. But it will do for now at least.
Vent hole here also.
I will mail you some upholstery thread as an option to the fish line. I find it communicates less resonance to the platter than fish line.BTW, if you have a high torque motor, the prat will continue even with a change in the viscosity. If you heard a difference between gun oil and motor oil, then you might have a lower torque motor.
I used Wahl oil (for hair trimming) in my TD165MK II and got excellent results.
The Mobile one I am using on my thread drive is 0-30 weight Mobile One. It is the lightest weight of the motor oils Mobile 1 produces. It is not as light as gun oil.
Great read....now have you registered yet on the Asylum?
Not registerd yet I'm afraid.. ;) Been too lazy. Maybe it's time to do that too.. =)

Many turntable manufacturers seem to not recommend motor oils because they contain detergents. As a matter of fact, I've never seen a manufacturer recommend motor oil, as popular as the idea's become. You can buy synthetic 30 weight oil without detergents, but it's hard to find.I've seen manufacturers recommend Tufoil, Marvel Mystery lubricating oil (slightly thicker, older tables), Marvel Mystery Air Tool Oil (slightly thinner, newer tables, very high-end, close tolerance bearings)... Many sell a lubricant that looks like a good quality lubricating / sewing machine oil to me... Due to the close tolerances and polished surfaces in turntable bearings, anything thicker than 30 weight may offer less protection against friction.

Can you tell me the brand of fishing line you used. I have the Scheu Premier MkII with 50mm platter and tried Stren super braid 20lb./0.25mm and it made the motor pod vibrate more than the stock line. I wonder if I should try a monofilament version, and maybe a lighter weight. Any suggestions would be helpful. Thanks

Yes, monofilament is what I use. The brand is: UNYL - winter liene 0,25mm /5,6kg. This is probably though just basic department store stuff, costs 2,50 euros for 50 meters.
Do you use a record weight on the table? I am thinking of getting one and was wondering how much weight I could use and not affect the motor. I have seen weights around 300g - 350g or so which I am sure will work, but the one I was thinking of is 2.9kg (6.5 lbs.).
I use the Scheu record weight. Its 800 grams. I wouldn't put on anything heavyer though. 800 grams is plenty to flatten the record (from the middle anyway..) The 2,9kg seems like over kill and probably not a good idea considering the bearing. You could always ask Ulla Scheu though. She's an nice person.

How do you splice the ends?
