Using a DD table as motor to drive another table

I have an old Denon DP-52F turntable. After reading the thread about turntable speed, I have a newfound respect for accurate and consistent speed.

It occurs to me that I could modify my old DD Denon to drive the platter of my SME 10 table via a thread drive. I have to get out the old table to see if it has variable/adjustable speed, but could this idea work?

I could just listen to the Denon and compare it to the SME, but the cartridge, arm and wiring are all different. The SME should be the superior table in most ways, but the direct drive of the Denon has me intrigued. Has anyone tried something similar? What are the issues involved and how should I get started? If the two platters have the same diameter, the speed should be close, hence the importance of variable speed on the Denon for any minor speed adjustments. Any advice would be greatly appreciated.

It works great except it takes up a lot of table space. Do it.

I used VHS tape to drive a passive platter with a DD table. Make sure you use a table with speed control. Models I recommend are Technics SL-M3, SL-M2 and JVC QL-F6, all have flat rim for the VHS tape to ride on. Other models will work too and you can also try thread drive. VHS is the only interface I tried so I vouch for others. You get the speed accuracy of DD but the decoupling of the tape filters out the cogging so you get "belt" drive table with the advantage of DD minus the sterile sound. The set up is a hassle at first, I have to say... but you get to realize how poor the motor is in many belt-drive designs. If you have the table space and time, once set up it's pretty stable. I don't have the space to do a set up like that anymore but it works. Have fun.

My previous post was intended to say "VHS is the only interface I tried so I CANNOT vouch for others."

Fat fingers. :-)
