High frequency vibration on Y axis

[spro]

I'm glad you worked it out. Just a piece in the puzzle.

Amplitude and frequencies' modulation / demodulation were the ways which allowed us to reach another level.

Mod and demod is way old but..I knew the pages. Carrier beat frequency to individual sections. Every frequency Was already special in it's way. More than that, each was a certain place.

Very interesting Spro

This might sound funny but I fixed it using some industrial sized heavy rubber bands. I put three on the leadscrew at the very end to act as a dampener. It seems to work like a charm, I can't get it to resonate any more no matter what I do. I'm sure something else would work too but this is what I hand on hand.

Not funny at all. Works for boring bars on the lathe too. Oil may attack the rubber, though. Best to use neoprene.

Thanks John,

I have some neoprene that I can cut into rings.
