Epoxy Granite and the Mini Mill | Page 3 | The Hobby-Machinist
If you want damping, you want lossy materials (not solid concrete, it can ring like a bell); you also want lots of scattering. to prevent resonances. Steel and epoxy are expensive, I'd think ceramic (tumbling stones, for instance) with. higher speed-of-sound than steel, mixed with plaster of paris (soft, low speed of sound) would work well.

Filling steel tubes with epoxy granite- machine before or after?
It'd take $100 USD of epoxy to fill the steel gantry in question with 20/80 epoxy/granite, which isn't a huge expense but definitely more expensive than just going with a larger or thicker tube. And I think the gantry tube in question is plenty big enough anyway at 8"x6"x3/8" for a 26-30" length.

8020 Extrusions with Epoxy Granite filler?
I saw the thread elsewhere talking about the massive stregnth and rigidity coming from homemade epoxy granite. I was thinking of building a frame out of 8020 rails, and then capping the ends and filling 1-2 channels with epoxy granite for rigidity. Shouldn't hold too bad for weight, and I figure it'd give enough added strengh to handle deep cuts.
Thoughts on adding vibration dampening materials inside a CNC
More epoxy granite, cf or fiberglass etc) or to add something softer as a a further vibration reducing measure. At this point, I don't need to fill the void with hard materials like epoxy granite for strength or stiffness. There is more than enough strength and stiffness already in the 7"+ of carbon fiber, epoxy granite and steel.
