Hello there. I have a turntable without a tonearm and I have a tonearm to put on it. But the deck of the turntable is too small to mount the arm the correct distance from the spindle. I could make ugly cuts or cantilevered panels but let's just not. But suppose I mounted the deck on a heavy panel and mounted the arm across the top of the deck. The platter is close to the edge of the deck there, and I could cut a hole into the wood anywhere with a clean conscience. But that places the cable exiting the arm right next to the motor. I guess that might be a bad thing, right?
I've seen this method suggested but probably most suggestions are from people who have never done what they suggest. Has anyone done this? Have you run into hum problems from the motor?

Hi Straight,
No, it's a rim-drive table and there's a whole bunch of parts between the motor shaft and the rim.

But you know what, I think you solved my problem. All this time I was thinking that the motor was up in the northwest corner like it is in belt-drives, but since you mentioned it I just went over and looked and it's in the southwest corner. So I can run the tonearm across above the turntable and it won't be really all that near the motor.
I drew it up and it looks kinda goofy but kinda cool.
So anyway, Thanks !!

Long tonearms make sense geometrically, the issues are around maintaining the spindle to tone arm pivot distance and preventing any relative motion between the tone arm and the platter assembly.
Hi Marcus,
I would make the pod heavy enough to resist movement. I would also use materials with a large coefficient of friction for the contacting surfaces. Later this year I am going to build an experimental turntable with a freestanding tone arm. I intend to design a decorative but precise locating gauge to be placed on the common turntable and tone arm mounting surface to monitor the correct location of the tone arm pod relative to the turntable. As I am writing, other solutions are occurring to me: The area contacted by the pod could have three Velcro pads located in recesses 120 degrees from each other with similarly located opposing Velcro pads on the underside of the pod. The Velcro pads should project slightly from their respective recesses so that they are slightly compressed when the pod rests hard on its locating surface.
Sincerely,
Ralf
Hi, The Temaad Pod 3 columns are filled with lead shot, also the adjustment spikes nestle in keepers.

I suppose you could get an optical table and bolt everything down to that if you really wanted 🙂
