Article in the most recent 'Model Engineers Workshop' magazine.
This involved a project to reduce chatter on a small (X1) mill.
Part of this was to fill the hollow column with epoxy granite to add mass and as a dampening medium.

The outcome was very positive with a very heavily damped column which had not vibration problems and which reduced chatter markedly on this light mill.

Might be of interest, not as a bed or solid mass of a machine tool but to add mass to one.

John,

Thanks for the reference. I've asked a friend with a subscription to let me borrow the issue when the mail scow finally lumbers across the pond.

I'm still actively working on this but most of what I'm doing right now is work on my lab infrastructure which means very little actual research gets done presently.

Regards all,

Cameron
