I make these in 2 pieces, W. Mackenzie makes some of these in one piece and then cuts them open at an angle for the lid seat, I always thought those were kinda tacky. This is a piece that can show a high level of craftsmanship if you let it.
I create this sort of flange on the bottom piece to hold the lid in place, the lid is pretty much just a bowl. I leave the pieces attached to the bats so I can adjust the fit if need be when they stiffen up. The lid is trimmed in place on the bottom piece.
The feet are trimmed out like a regular bowl. The cuts are made with a cheap cheese cutter with the plastic depth gauge removed. Sometimes I make some of these with a tri-foot which is much trickier, I think it tends to look a little too delicate for stoneware.
This is what it looks like completed. Well, ya know...if blogger could keep the orientation correct.
