I think I am going to attempt to make turntatbles

First off let me say I am not new to the audio realm. I am a computer engineer and yes I realize that deals in ones and zeros. However, I have made a few custom guitars. I know a master woodworker and a talented machinist. I have been searching for that perfect table for years whilst living in mediocrity. Well, I have the resources; why not make one from scratch. More than likely I am going to attempt a belt drive unit at first using an off the shelf arm... More than likely an SME. I am working on the power supply circuitry right now as my piece. Any one have any tips... I am thinking solid, large mdf plinth with an attached copper mat and either a heavy plinth with an acoustically decoupled motor or completely detached. Thoughts?

That is the way AJ Conti of Basis and several other manufactures started; they didn't like what was on the market and thought they could better. SME got into audio because Alistair Robertson-Aikman [probably misspelled] didn't like the arms available and had his machine shop build one.

I tried and gave up.There is alot more involved than you might think

Buy a VPI Classic 1 , 2 or 3 and be done with it.

Agree with Vernneal. It only make sense if you enjoy the process of designing and building by itself. I do, so I'm having lot of fun along with enjoying the music on the long run; I also have learned great deal about audio. Otherwise, it is not justified economically; lots of excellent second hand TT on the web market.

I'm assuming this is the case, right?

Good initiative!
Through experience, I strongly suggest the following:
* purchase off the shelf platter (many offerings, "Scheu" is one of those) and well -- or tyou can design & machine he latter yourself (a mechanical engineer will help tremendously).
* work on a (electromagnetic) elevation system for the platter -- i.e. a magnetic bearing; get rid of the bearings friction.

Good luck!
