If you want to make a decent main bearing for a low cost DIY TT, take a large brass bolt, and drill a 1/4"hole down the center. Polish it up inside, and use a long 1/4" non-tapered roller from a roller bearing. Push this into your platter all the way through, and it is your spindle. Get a brass nut that fits the brass bolt, and bolt it to the center of your plinth. Put a small ball bearing in the bottom of the hole, add oil, put in the spindle/platter.
You might have to try this a couple of times to get the bearing clearances just the way you want them.
It's about the cheapest way to go, and alot of older TTs had bearings very similar to this. The 1/4" spindle diameter is not as heavy duty as some of the newer bearings, but if low cost and basic workability are the criteria, then this will work for you. It is not going to unseat any of the world championship TTs.
For the motor, I'd recommend just getting an AC synchronous motor from an Goodwill turntable, and using that. Make a pulley that is correct diameter for your platter. Most sub-$1k turntables use basic AC synchronous motors.
