I just wanted to give an update on milling limestone with my shapeoko. I ended up making a “milling bath” with some cut down plastic buckets. I ended up making a “water shroud” to contain the splashing (so far it’s working out great!) The milling bath is working great, I haven’t had any dust accumulate. If anyone is thinking of doing something similar I’d be happy to share my lessons learnt.

wow that is amazing! What speeds and feeds and bit did you use? Also where did you get the material?
For most of the cutting I used a regular 1/4" end mill. D.O.C 1/4" Feed: 35in/min Optimal Load: 0.06in
For the detail work I used parallel passes with a 1/8" ball end mill. Feed: 50in/min Stepover: 0.01"
I was given the material. A friend is working on a project for a church and I am helping him with the trickier pieces.
