tell me some more, if you agree...
Tony,
Congrats, this is a very fine design for a diy t/t 😱
I took the liberty and placed your t/t's picture in the turntables' section of the A.C.A.'s web-site (http://aca.gr)
Please look at: http://aca.gr/turntable_b.htm#diy and, if you give me permission, i will keep it there (just need 10 words of construction details, arm/cart on it and your or the designer's real e-mail)
If you do not agree or you want to use your pic for some other way, please, tell me to remove it.
In some time from now, all DIY t/t pictures in that page will be moved to a special section of out Photo Album (http://aca.gr/forum/album_cat.php?cat_id=2), where somebody can make comments below the pictures as well... 😉 )
Keep up with the good work

skaloambakas,
You got it all wrong ,I just got this TT pic from the website I did'nt make it.(I wish).I just wanted to show an example thats all.
Apologize if I misguided.
Thanx,
Tony.

When you are dealing with 200 t/t pictures...
You have confused me.
Funny thing is that i later discovered that i had been including this t/t in my Gallery a long time ago ( http://aca.gr/turntable_e.htm ) and it is not a DIY but the Transrotor Orfeo, w/ Audiocraft AC-3300 dual uni-pivot arm.
You made a foul out of me... but I am still loughing - no problem...

rcavictim,
Beautifull platter. How did you "laminate" the 2 pieces ?
Question where is situated "upstate Ontario"

Hi Alain,
Laminating was very time consuming. I cleaned the mating surfaces scrupulously. I mixed a small batch of that two part water-clear epoxy sold to replace 50 coats of varnish on counter tops. The product I used was made by Behr and called "Build-50". After mixing it in proper proportions I poured it into a large mouth drink bottle that was absolutely clean and pulled the bubbles out of it for a full half an hour with a mechanical vacuum pump. The stuff foamed for a very long time. Once it was outgassed I carefully poured it onto one surface of the pair and pressed the other piece on. I then applied clamp pressure and in the process, despite all my care, was horrified to see tiny bubbles appearing despite the vacuum pump work. I was able to squeeze the bubbles away with C-clamp pressure. I left the clamped assembly under clamp pressure for two days in the warm house before removing the clamps. I was then able to cut a circle on the bandsaw and mount the piece into my lathe to turn it.
This material does not have absolutely parallel walls and I had to face and polish one side to match the other. I also polished the OD. It came out very nicely and runs absolutely true.
Upstate Ontario is a cool place (highest altitude) NW of Toronto! If New York can have an area that is named to sound trendy, so can we. There is no 'Downstate Ontario", I guess the same reason there is no Downstate New York. 😀

rcavictim,
Thanks for all the explanations, I want to build my own TT so I am asking questions...
I think there is an other product to laminate the pieces, I have been making my own flyfishing rods and have used clear Gel-Coat for all wrappings
its called "Flex Coat Rod Wrapping Finish", its clear, without bubbles {a few number of very small ones still exist...}
and makes a very strong fixation on Carbon blanks,
http://www.americanfly.com/retail/c...9427&mscssid=SM3A0G05GKJR9G6EJ8DVKVTCULKN2UX5
About upstate Ontario, I was thinking of the Algonquins park, where I go camping in summer.

Alain.

A;ain,
A single thickness of this plastic would make a fine TT platter. I wanted the ultra expensive 'plus sized' look. I think it is a 'guy' thing. 😀
Remember that you have to use a bonding agent that does not require air contact and evaporation to cure. This rules out most glues except epoxies, which the stuff I used is a form of.
I used to work for the NRC and was stationed at the now closed Algonquin Radio Observatory in North Eastern Ontario. It was buried deep in Algonquin Provincial Park. We used a logging road from Pembroke to get in there. That area of Ontario is definitely 'upstate' IMO. Very beautiful country. I miss living in the forest on a lake. With no neighbors to bother for 75 miles I used to push my full Altec Lansing VOT commercial sound system with 1200 watts RMS and eight horn loaded speaker cabinets outside and crank it up full. 😀

Hi,
Just (allmost) finished my new deck - "The Monster". Approx 120 lbs of analog record turning machine. Just remains to make the armboard for the 2nd arm as well as getting some cables fixed on my TT.
A lot of pictures on how I made the lead-damped base as well as other details on my site:

Hello Jan,
Very nice design, could you explain more how the platter is drivin or more specifically how you keep the platter centered?
It looks like standard belt drive but I imagine a normal belt configuration would pull the platter off center causing friction between 2 pcs of metal. This would make the advantage of the "floating" platter gone.

Hi Eric,
Basically the bearing is the same as the Platine Verdier. A very solid almost 1" rod with a ball on the top. The magnetic suspension is only to lessen the vertical pressure (weight) on the ball. The magnets lifts more than 20 kg leaving only around 5 kg pressure on the ball.
The drive is now with a thin string using a DC motor supplied form Scheu in Germany.

Mag suspension
Hi Jan,
Nice job, looks solid: well executed and thoroughly thought after.
Just curious: did you have a chance to compare the sound with and without magnetic suspension? Does it realy need help to bear the load? I'm going to double my 16 kg platter weight, and the bearing capability becomes the issue.
I would also like to get some additional details: thrust plate material, type and location of magnets, if you don't mind.
Regards,
Michael

I always thought there was no mechanical contact at all between the platter of Verdier La Platine and it's base.
Does anyone know if the Forsell and Rockport airbarings also have mechanical contact or are they fully floating?

I tried your website. Why is it so slow? It is painfully slow even with highspeed access. Very nice collection of DIY turntables you have there.
