2016-07 Concrete Record Player.

The Dual turntable needs somewhere to live. I decided to make this a test of the process for my ideal record plinth.
The Concrete Record Player (plinth.)

The process: Make a mold and fill it with concrete

The mount points for the turntable are precise and too thin for concrete so I made a frame of plywood to be embedded in the plinth the the turntable will rest on and mount to.
I made two and laminated them together for strength and the depth needed for the turntable spring support cups.


The frame mounted on the top of the mold with the turntable cutout under it. The frame protrudes and that will keep it embedded in the concrete. Here I am packing out the interior with packing foam and masking tape to keep the void in the middle empty.
The mold with the sides on and some dowels for the mains and audio cables. I didn't want to risk cracking the plinth by drilling these out after it had set.
The first  concrete is in and you can see the wire squares I added into the concrete hoping it will strengthen the final block.
