what's causing a SME 3 to stick after a few spins?

How hard is it to push the arm across the platter in the raised position? Or does this "locking" only occur when the arm is down at the record surface level?

> Does this occur with the AS turned all the way off?
> When it 'skips', does it skip toward the center or outside edge of the record? Or rather, by 'skip', do you mean it won't track (keeps playing the same groove over and over again?)
> What Sutherk asked -- does it resist horizontal travel when the stylus is slightly above the record. You can check this by looping some thread under the TA wand near the headshell, and with the lifter down, AS off, stylus guard in place, hold the thread in one hand suspending the cartridge end of the tonearm just above the platter, and holding the thread, try gently moving the arm across the platter in both directions. If the horizontal bearing is seizing, you'll know right away. Are you the original owner?
> As far as I know, the only silicone damping in that arm is in the lifter mechanism, and the swiveling DIN plug. So I can't see how any would get into the horizontal bearing?

The problem occurred when I first hooked up the turntable after arriving from Fed Ex. It eventually improved and then returned after I adjusted the overhang. This mis-tracking went away also and now seems to be working just fine.
By skipping I mean it gets stuck in the same groove. When I raised the arm and and gently pushed it towards the spindle I did feel a little bit of resistance.
I'm not the first owner and the person I bought it from wasn't either but says it was set up professionally.
I'm going to change the cartridge and see if the problem returns.

Leisual, you're getting warm, but please try the string technique as it's the more sensitive then the "gently pushed" method ;--) I think changing the cart is a good idea just to eliminate that possibility (leave no turn un-stoned ;--) however I'm not optimistic :--(

Then post your findings and I can at least give you my advice for what it's worth ;--)

"Luckily" after playing through 3 sides without incident this morning I got stuck in a groove on the first track of the 4th side. I found some thread, looped it around the arm like you said, lifted it up off the lp and tried to move it toward the spindle. I definitely felt some resistance where it was stuck and once I moved it past that point it was moving fine.
The cartridge, by the way, is a nearly new Rega Bias 2 tracking at 1.75g.
