Anyone "Handy" interested in a DIY Turntable Project?

I was after some quite a while back and all I could find was this.

You could try foamed butyl rubber .....aka exercise mat from decathlon 15mm thick approx ...it has some of the properties of sorbthane...but not all!

found this !

 

Thanks for the posts / ideas, I could use my Yoga mat, now I have had to pack it in after it buggered my lower back

Am I correct in thinking sorbathane is a type of foamed silicone rubber ? If so, I do have a source for a self mixed foamed silicone, I have tried it out, and it produced very good results. Poured between two spaced glass sheets would I imagine produce a decent mat.

 

Not certain as to the sorbthane construction process, but could be.
Its got to be worth a try as sorbthane is very expensive.....

The foamed butyl rubber works very well between sheets of MDF or similar and has a marked attenuation of the mid and higher frequencies of transmited vibration.

I use a stethescope to listen to the floor and then the isolation and you can clearly hear the attenuation. This is done by dropping a ball bearing from a set height onto the floor,and listen at equal distances from the impact.

 

Hi Uncle
I have been thinking about the deck and testing some suitable sheet material (plywood). I have some very thick chipboard that I have just rediscovered during a clean up session. I think it may produce better results than a plinth produced only from layers of plywood . It is a great deal more dense than the plywood I have sourced as yet. The only problem I foresee is the edge will look nasty even when filled, any concerns if the edge of the deck is finished with a black lacquer ?

Have you made any decisions re the feet ?

regards

 

Hi Granville,

Been up to my eyeballs, so sorry about the tardy reply.

Hmmm. Chipboard ... well, I like black lacqeur so long as its smooth and slick looking nasty even when filled doesn't sound good though.

Re feet. yes. I have them on special order. Probably take about 4 weeks. Alumium cones with a sorbothane insert.

 

Feets

Granville,

Feet not arrived yet, but did take some pics of an identical set to give you an idea:

​

Black powder finished aluminium with some sort of rubbery stuff in between. height is give or take 33mm and the diameter about 40mm.

 

Help with a motor?

Figured I would see if you guys could help me

Need an SY31 Premotec motor (110v 1.8mm shaft, 60hz 300 rpm) for a Systemdek IIX table.

I try contacting Premotec but they won't respond to emails. (They are 9hrs from me so calling is hard)

I searched the web for US distributors - all I found was MVR and they can't get it. I was told McLennan in the UK could help me but haven't received a response yet. Any ideas?

 

We can get something same spec I think. You have a PM.

 

Still not dead, yet

Sorry Tony
I have had the worst few months ever, total unmitigated crap crap crap, may well decide to close down the sign business. just can't stand any more of this shit.

I am still up for making this deck, it's just I have had no time
what so ever to put into it. Plus no spare cash at the moment.

I have a big exhibition job during November, and if that doesn't finish me off, I will attempt to get it moving again in december.

There is a slim chance I may get my hands on a cnc router, this
will make things easier, as I wont be dependent on getting it cut by idiots who don't understand the differance between cutting inside or outside the vector. The first attempts were cocked up !

I'll attempt to keep in touch a bit more

best regards Ian

 

Motor Pod

Hi Tony,

I discovered this thread a little bit later, but am in the process of a DIY turntable project myself. My design is close to the DPS mentioned earlier in the thread. I've assembled a platter from a Clearaudio Champion, a Michell armboards and a DC motor from a german specialist called Scheu. I've got a dual-plinth design, seperated by a set of the sorbothane pucks that VPI used in the HW19 series (VPI used these with a stand-alone motor, so I'm hoping I'm ok in terms of lateral pull).

The only issue is I'm having is with the motor pod. I had intended to make something myself, but don't have access to a machine shop and having one custom-machined for me is well beyond my budget.

The pod that you used looks perfect - do you think you might be able to find another one for me?

Cheers,

Henry

 

Scheu will sell you a motor pod as used on their decks.

 

Yes Scheu, or if you PM me I can give you the spare parts prices for the RPM9 pods.

 

Granville, How's things? I hadn't replied because I hadn't realised you had. Hope things are going well your end.
