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. |
