I did a thing!
Just preparing the concrete mass damper for the CNC table.
The concrete mix kinda got a bit too wet (water should kinda not be seen on the edges) but I wasn't able to mix the whole bag as hard as I tried.
Oh well, it will be fine, hopefully.

As expected, the wood swelled up and the legs separated from the board. My other table did the same, it got back to normal...in...a month or two?...can't remember exactly.

@Nixie@nixie.name how do you design such things? Do you aim to move resonant frequencies outside of some range, or do you aim to cause energy dissipation?

@Nixie@nixie.name wetter is often better, prolly not a bad thing! Looks like a great job and you are way braver than me not working on some cardboard or something :P
