I got bit by a dumb idea earlier and I realize now that I will persue until it is complete.
I want a display at the maker space that says "We made this"
The display is a nice shelf, a good custom cabinet, with a turntable sitting on it, running in to an amplifier, and some speakers. There is a record on the turntable.
We make the shelf, the cabinet, the turntable, amplifier, and the speakers, we cut the record, we record the music.
Under that is a sign that says "all of it."
I'll use an off the shelf phono cartridge, and a really simple tone arm. We'll supply some basic friction based antiskate. At some point I might try and get fancy and do my own cartridge, but that's a level of precision that I'm really really bad at.
We record music in our recording studio on a regular basis, I have a recording lathe for cutting records. I can probably do the cabinet on the laser cutter too, but Ryan's got a full woodshop in the basement of the other building.
I have a backup, if I'm unable to get a turntable built from scratch.
We have a couple of broken tables, one of which was built in, like, 1948 or so. I can repair that and use it instead if it comes to it. I'm better at repair than at new fab.
Alright! I have adequate some serious progress on my turntable design.
Turns out, I get real foggy when I don't eat or drink anything between 9pm and 2pm.
Once I was no longer foggy, I started laying out the components in cad and working on the laser files.
I'm learning cad for the first time, so this is slow going.
I know which parts I need. I have the motor and belts in transit. I will laser cut the platter out of acrylic and make the plinth in wood.
I'm using an off the shelf bearing assembly for now, but I may alter that in the future.
I will add acoustic isolation to the motor and other things of that nature if it becomes a requirement, but I'm starting simple.
Tone arm will likely be solid wood on a simple 3d printed gimbal/hinge. Grease it all up well enough and even plastic will perform well.
I'm starting with an off the shelf phonograph stage, and a home made amp. I'll probably build a phono stage at some point.
I think I'll vacuum form the amp housing and do it up like an old radio.
@DHeadshot I read that the first time I went down this road in 2012 or so. Probably a fine table. Mine should have fewer potential points of failure.
