You know where I am... sadly being 1000's of miles away, I cant offer the help of a soldering iron, or a six pack, to inspire the project onwards

Talk to you soon

Hello to all and above all Casey,

I only read this thread now for the first time.

I think we all will need to wait for the bearing/motor group buy. Casey when you settle everything you will have a paying customer (discounts for pre-donators?)!!! It must be soon because I would like to do a similar project in December.

In boca al lupo (good luck in italian jargon),

Default Settled dust ?

My my...I just wandered back onto DIYaudio... I remembered following a great turntable build which was based on using Corian acrylic sometime back - Todays date is July 9th 2009.

There's a block of multi-layered Corian that resembles a TT gathering dust somewhere

I guess the dust did settle after all...(!)

I trust you are well Casey ! -Andy-

Been thru it before. Never easy, even if you are the one that wants it. Life goes on, but slowly at first. Wake up each day, pray for the knowledge to do the right thing for that day and hope that it will be a good day.
Best of luck on your new life. I kind of know a little bit of what you must be going thru right now.

Default spring coupler for AC line direct drive sync' motor?

Click the image to open in full size.

RTV silicon glue. I applied it in three steps. First I compressed it so the coils touched, and laid down about a 1/16 of an inch. When I let it expand, it pulled the silicon in between the coils. I let it sit over night, and when it had cured, laid down another 1/16”. Finally, after it cured again, I filled in any voids, and ran a fillet on the ends. The entire process was done with a 1/8” shaft of a Dremel tool inserted to insure a perfect alignment as the rubber cured. How does it work? Oh...My...God. Not only does the silicon damp the spring resonance, but apparently it helps kill the motor noise at the source. So much so that I can no longer hear any motor hum while it's hanging on the “kinda horn” noise amplifier outside the housing! You can believe I'm grinning like a Cheshire cat now. Whistlin' while I worked, I reassembled the motor, and set it up on table. Fluorescents off, screwdriver pushed in my ear, I went hunting for noise. Side of motor housing..nothing. Top plinth..nothing. Bottom plinth..nothing . The only mechanical noise I could find was on the motor's top plate. The side load on the bushing from the belt increased the top bushing noise from zero to something slightly greater than zero. The top plate acts like a sounding board for any noise the bushing makes. I had actually anticipated this from the beginning..why I cut a recess in the top for a Sorbothane donut. I'm sure once this is in place, this minuscule noise will be gone as well. As for airborne noise at the belt, all but disappeared. There is no longer any belt vibration that I can feel, and the noise level has dropped to the point that all you hear, with your ear practically touching the pulley, is a combination of belt hiss, mixed with a faint bushing noise, and a random static crackle (the hiss may be static as well)...Casey
Question for C or other interested parties: Could Casey's revised spring coupler be used effectively for a direct drive 33-1/3 rpm AC motor to turn a turntable platter?
...regards, Michael
