My DIY Turntable is finally done

kilowattski · 19th July 2009, 10:59 PM

My DIY Turntable is finally done! It took two years, but I think it was worth it. It would have never happened without a lot of help and encouragement from Vinly Addict. Thank you Frank. The table has a DIY Motor Controller and is equipped with an SME IV Tonearm and Clearaudio Maestro Cartridge. In the future, I will try a Platter made from a different material, inverted bearing and different cartridge. Here are some pics.

Bloody awesome feat of diy engineering.

Please please tell us the details.

Nice machining. Seems like the motor-pod and arm-pod are made from the same material and both are sitting on the platform the same manner. Don't vibrations travel from the motor to the arm this way? What's the concept behind the idea of completely decoupling the arm from the table? Shouldn't the arm and platter vibrate in unison if any vibration occurs? Again, impressive machining. Hope you are enjoying the sound.

Both the motor and toneam pod are heavily damped with lead shot and silicone fluid. As you can see the turntable is mass loaded and very little vibration is transferred because the plinth is also damped with lead shot and slilcone fluid with tiptoes and the whole rack is on tiptoes on a concrete floor. I should however put an accelerometer on the table just for grins.

Yes, it is very easy on the ears. I have Jazz at the Pawn Shop on Vinyl and there are things present that I swear I have never heard before compared to CD. My next project is to come up with some sort of record cleaning device to clean all my old Vinyl.

i also see an air bearing tangential tracker in your future!
