Platter material question

[studiorp]

Hello to all, I have a doubt : better have a brass platter, alu or iron ?

I am interested about the vibrations that can be transmitted by the cutting head to platter, so which of three options ?

Thanks.

Any suggestion ?

I make mine out of aluminum. It's cheaper than brass. And more easy to work with than iron. I wouldn't worry about vibration in platter. I worry about vibration in whole machine.

Hmm, is there someone that use acrylic platter here ?
Could be a solution...

Acrylic is not the best , its expensive, it cracks easy. Not much tensile strength, no weight to it either.
