The link below was the source of the idea. It was the third HDD I tried. :)

Hi Fellow Trolls!

I have a plan to see my scavenged neumann platter spin. I try it make cheap to save money to a decent cutter head, so i put the whole bulid onto an HDD motor used as a precision bearing.
It works, no problem with the 15+ kg mass, spins for looong minutes. It will be a belt driven solution, like an old western electric turntabe/cutter.

Any ideas/solutions/anything for a cheap but acceptable bearing or any experience about HDD bearig??? Thanks for the answer PM-s! :)

Some progression... Myshank blank with wax and a diacustic styli. Introducing Jim Morrison featuring some rumble and surface noise :twisted:

Next time I'll use a diamond styli :)

hello, congratulations on the project is going very well.
My project is very similar to yours, I'm actually in version 6 of my cutting head.
I have had good cuts, and good sound quality.

After a big break, i came back to the cutting. I almost finish my lathe, i bought a diamond and blanks from myshank, but i'm not sure about the cutterhead weight measure.
I use a jewel scale, at the same height as the surface of the blank. I set the weight, but its seems too light, its 15.6 grams I'm a little nervous, i don't want to destroy the sytlus with the first try. ANY suggestions???

Thank you guys!

Status update!
The digital jewel scale went total crazy because the D1 magnet. Every measurement went to negative sign, so i droped this solution. Next one will be a micrometer scale like myshank mentioned http://www.myshank.com/scale.jpg

OR Any other idea? Thank you guys! :idea:
