I just finished a wooden plate to hold three diamond stones in the vise at the bench. I used a chisel and router plane to get the stones into the plate. I took inspiration from Paul Sellers, but made mine a bit bigger so I could mark the 30 degree lines for chisels and plane irons right on it.
I think I'll use a magnet to help secure them into their spots, instead of silicone.
I'd like to be able to take them out as needed.
For those that use diamond stones, what liquid are you using?
