Stones I'm using are on the William's wand, which is 3/16" OD. I have some wand blanks that I'll be working on, to use with standard MFL fitted stones. Even though those are all 1/4" MFL, the wand is 3/16" and the hose I have is 3/16" ID. Doesn't matter much since you can put 3/16" hose on 1/4" barbs, you just need to warm/soften the hose first.
