Wanting to combine two of my passions, wood and music, more precisely, a turntable (I know, why doesn’t he just do a cabinet like everyone else!). Saw this and was really impressed and thinking about doing one myself.

Anyone done one? I was thinking about using solid wood and putting some inlays in there. This one is MDF and they added lead weight for ballast. complete thread is at http://www.diyaudio.com/forums/analogue-source/35189-my-diy-turntables-diy-tonearm.html
Any thoughts? Not sure if solid wood would be the best sonically, would still hollow it out and add some weight (balance issues???). Ideas? Comments?

Not having read the article(I will later) I’m guessing MDF was used for stability. “Wood moves, get over it” is a common quote, and it is true. If not MDF, then maybe Baltic Birch plywood. As for ballast, I’m guessing this is to act as a flywheel in evening out any speed consistencies with the motor.

This looks like a cool project. Go for it and report back.

You can see lots of pics on the article. I was wondering if wood was too unstable, I mean the tonearm can allow for a small amount of imperfections plus add a nice mat would help too. I would really wanting to throw some walnut and ash pieces in there before she hits the lathe! Also, the weight isn’t so much to maintain speed as it is to make it less sensitive to sonic and other vibrations, but I am sure it helps with speed control, too.

Wood is more likely to have it’s own sonic character or coloration….you might like it better, you might not. MDF is more inert and acoustically neutral…which I think would be desirable for something like a turntable that should reproduce only the sounds on the recording with as little signature of it’s own as possible. You could add veneer for the aesthetic value. There are other inert choices too.
