did you use a 1:1 ratio for the drive and load pulley?

Yes we took the trouble of taking a motor carefully apart and getting rid of the coils etc...and use it in its empty housing...

We mounted it (you have to buy 2 boomboxes...1 small tiny white wheel per machine ...hahahahaha) with a second motor this time one powered and with a little tension on the belt.....and GO

Obviously it was an experiment and although it worked it had loads of jitter....(a lot of difficulties to overcome....first spindle/platform/belt/second spindle ..it all has to be perfectly straight but it is NOT....etc etc)

I will not go as far as making a better spindle (couple of mm thicker) with ball bearings and oil etc etc....We reckon it most certainly will work but the mounting as I have planned will suffice more than enough for me...

I probably have still some photo's of this experiment at home..I will search...

Hi Erik, have you tried tuning the PS.?Here
I know you like to experiment and you also have the ears for it
I'm sure it has made a difference to mine..

Audio1st, how do you create those nice images you always post ?
What value did you come up with for your ps?
I quickly tried some values, and it changes the sound for sure.

Hi rikkert1978,
I use Adobe Photoshop, the secret is adding "layer style", to bevel and emboss the lines.
I've used what I had handy so far, that was 1nF on a 50VA and 2.2nF on a 100VA transformer.. I hope someone with a better system and ears might find the "right" values?

Could you describe the character of these changes please, just to know what to concentrate on when listening?

No I have not although I do use the wimas in other positions..

Today I took some time to built the mock-up to get a good feel for sizing and design...

This way I know later on how to exactly use the expensive ebony/copper/acryl....etc.

The powersupply is imitated by the crosswood between the frontlegs..

The height is approx. 75 cm.

Erik, that is very cool and beautiful work, but you are a madman! I bet it sounds awesome. How much do you think the stand and player together will weigh?

Ok, I am over my summer model aircraft frenzy and ready to build my Shigaclone. I want to do a Peter Daniels-style bronze/copper frame and am looking at metal sources. So far I'm looking at OnlineMetals.com. Any other sources worth seeing before I place an order?

Also, for another project, anyone know of a good online source for Corian sheets?

TIA!
