Turrntable With or Without Suspension?

Wall mounts also give you a built-in height advantage over the young'ns.

My wall shelf (see photo below) uses two of the heavy duty brackets you can get from most hardware stores. The brackets need to have that triangular brace. The invariably come in white, but you could easily Krylon to taste.

Mine happily bears quite a lot of weight.

Ngeorge:

My table's a Russco Cuemaster broadcast turntable. Popular in 70s and 80s especially on west coast, which is where it was built (Fresno/Clovis, California, just a drive down I-5 from where I was born and raised). The design matches other broadcast tables like Gray Research, etc. Built like a tank.

Being a large idler wheel table with a powerful motor, it wants to be mounted in a massive stand, hence the monolithic plinth I built. More info on my table project here:

It does not cast "ink black" backgrounds, but its virtues more than make up for that, in my book at least.

I got to thinking more about your situation as I was walking to my car last night.

If the table really needs to be in that cabinet, just make the cabinet more sturdy.

(1) Make sure no wobble on the feet. If wobble, fix with shims.
(2) Make sure no wobble in the construction. If so, some wood glue or some strategically placed screws can strengthen the construction.
(3) No wobble on the shelf. This can be fixed simply by adding weight to the shelf, in the form of bricks or whatnot, that will more solidly connect the shelf to the cabinet.
(4) Fix the top of the cabinet to the wall on both ends.
(5) For the turntable, consider making a "4-Vibrapod sandwich" underneath it. Some people pooh-pooh Vibrapods, I have found them to be good for the cost. Just take a while to weigh exactly what they will be supporting, and order the correct rating. http://www.vibrapod.com/

Good luck and enjoy.
