Hi, I'm new to tt repair, and this forum, (not sure if this is the right place to put this thread) but I'm fairly mechanically inclined and I figured I'd give it a try on this piece I found at a thrift store. When I bought it, it wouldn't turn at all. After messing around with it a bit, I managed to get it to begin spinning by turning it lightly with my finger, and now it turns great, except for when you put a record on, it becomes obvious it is turning slowly. I've pulled it apart somewhat, and have been very careful.(I'll include pictures in this post) I am not at the point where I need more help figuring this out.

Best first step would be to clean all the bearings in the transport ... that old grease turns to concrete over time. 3 in 1 oil should do a nice job of freeing those up. Ditto on the spindle ... that should spin easily. If it's a belt drive, I'd also plan to replace that - lot of that spinning slow with a record on the table could be due to the belt slipping.

Garrard table? I notice the "made in GB" on the platter ...

Also, what would be the best way to go about oiling the bearings? Should I use the 3 in 1 aerosol spray, or the liquid?
 
Liquid ... easier to control. Sewing machine or clock oil is good too. I use clock oil, because it's got a needle bottle, and I work on clocks, so hey, I got it anyway. <G>

I'd start with the spindle ... just let a couple drops dribble down the shaft and work it's way into the bearing. Give it a couple spins, a bit more oil, spin it some more, and repeat as necessary. Once done, you should have about zero resistance.

PS ... BSR built some solid tables, so it should be worth the effort.
 
WD-40, and its ilk, are fine and useful products when used as intended but NEVER use a spray lubricant on the mechanics of a turntable. When I used to repair turntables I had more than a few customers bring in their Duals or other automatics that were in fine shape except the customer had decided to lubricate the workings with spray WD-40 and it would no longer function. That, and similar products are a big no-no because: 1) They make a big mess that is a PITA to clean up and lubricate parts that shouldn't be lubricated. 2) The carrier is a really good solvent that will almost always dissolve and wash away the lubricants already there - good or worn out -and replace it with a silicone or other lube that is much too thin and inadequate for the job. 3) It stinks up the turntable and whatever room it's in. 4) Some brands are capable of dissolving rubber and rubber-like parts. & 5) Depending on the spray lube used, it may create a long-lasting fire hazard.

Basically, turntables and spray lubricants do not belong in the same county..................
