I got tire of the factory turntable drive throwing the rubber and belt. I installed a direct drive DC motor and it now works smooth and is very powerful.

I don't have as much trouble with the rubber band drive as I do getting bits of ballast stuck in the gearing. Right now I've got the hand crank on mine, but I do have a box-o-motors that I could try if I can find a decent meshing gear that'll fit on the motor shaft.
Good looking mod 
Great idea! What are the plans for covering the new motor?
Thanks,
Alan
Mr UP, nice job on the modification. I am glad to hear that the turntable is working better for you.
Ha! Yes, yes, I forgot to mention covering the motor. I am planning on a switch tower building...lol it will have to be two story for sure.
Couldn't you mount the new motor upside down below the board and extend the gear up from below?
Tom is right and you know after I finished mounting the motor, the thought of mounting it under the layout crossed my mind. Under mount is a great idea. I have a building in mind that should cover it, if not, under it will go.
Can you list the parts used and where you got them please?

I'd like that info too. One question, does the table still have indexing?

Wonderful! Great modification.
Yes, I'll post the actual parts later today. I just searched on Amazon for low RPM DC hobby motor. The motor is a 60 RPM motor. A 100 RPM might be better, but I don't really get in a hurry, so 60 is fine for me. The indexing feature of the turn table still works great. As for the gear, I just took a shot in the dark at that, and hit the target. I just made sure it would fit the motor shaft (5mm). The teeth perfectly match the teeth on the turn table...yep, that was cool! The bracket that the motor is attached to came from the same source as the motor, screws came from Lowe's. You will notice the corner bracket that connects it to the table...that also came from Lowe's. How do I power it? Good question! I had an old HO Tyco transformer from my childhood HO layout (don't throw stuff away) it works fantastic to power the DC motor.

Hi Mr Union, how did you get the two brass pieces to fit together ?
I bought all the parts and not sure how to assemble the two. Also top brass connector was missing teh set screw. Did your come with one ?
Thanks !
Mr.UP said he would list the parts, Porsche 1662 says he bought all the parts but doesn't know how they go together. Did I miss the post with the parts listed?
Coach Joe,
Ill be glad to relist for a fellow coach. All came from Amazon.
Number 1: 37mm DC Geared motor mounting bracket holder + 6mm hex coupling $5.32
Number 2: RioRand mini 12v DC 60RPM High torque gear box electric motor $11.99
Number 3: 32P (4mmBore) 16T Gear motor pinion gear $7.99
Now for the small screws to mount the motor to the mounting bracket I just took the motor into Lowes and got the proper METRIC screws.
Ok for the two brass pieces. The piece that is on the motor shaft will slip on the shaft no problem. So, how did I connect the gear to that piece? I drilled and tapped the shaft brass piece into the thicker hex end. Then I drilled a through hole to fit the screw used to fit the two together. The tap was either a 1/4-20 or 10-24. I used red locktite and screwed the two together then I slipped it on the motor shaft. Let me know if you have any more questions.
Ok thank you. I was wondering if I missed a part. Ill get right on it
Thanks !
Love your idea. How has it been working over time? Any problems with the table plastic gear on the table if the table jams?
This would have been a great You Tube video on how to do.
Rick.
