Emphasis on the relatively -- doesn't look easy at all, actually. Looks like you drilled those holes from the extruded aluminum tubing -- and inserted a long piece of foam to damp vibrations? Getting a tonearm cable socket in the baseplate of the tonearm is very clever too, and probably was complicated to set up. Nope, not easy!
But if it is simple for you, maybe you could make one for me!
I have a Technics SP10 mk2 in excellent condition with a power supply that was completely rebuilt some years ago. Made a simple BB plinth for it with 4 squash balls for isolation. I have several tonearms including Linn LVX, Rega-based models, etc, but they are all a bit too short to look right with the huge platter & plinth. What I need is a tonearm with ~10" spindle to pivot mounting. No desire to spend good $ on ridiculously priced old SME and other 12" arms.
This tonearm is not mounted, just sitting atop the board. It would have to moved to the extreme left/front edge of the armboard for proper mounting -- and that does not look good.
I am still curious about the ring that you made for your platter. Even though I like the idea, I would want it to be perfectly balanced as not interfere with the stability of the platter rotation.
Well yep , that's why I was so happy discovering the Supatrac, I'm not saying it's a weekend project it does need lots of tinkering until right, but with a good drill, patience and 40$ worth of material you can really go far. There are other nicer looking Supatrac copy on the net, worth looking them up.
Your turntable looks awsome, now it's time to put it on 1ton of concrete just for the sake of it 😀
Hmm, I was thinking of making a small rouler to verify it is perfectly positioned, but mehhhh, if it is unbalanced then I can't hear it.
What I do hear is a definite upgrade over a central weight ( or clamp)... it just sits better and seems to give the poor cartridge a better chance of the impossible- that is, tracking a groove.
There are some clones I found; none with any real details. I guess I'll have to study the pics & PDF of the original & see what I can do. Looks like square carbon fiber tubing can be bought in small qtys, and I already have a collection of small neodymium magnets... But your fabrication skills are way beyond me. I'll have to go real slow.
A ton of concrete? no. 😆 But I might replicate your gravel filled column. Will see how the wall mount does when a tonearm is on that SP10.
