.25" deep at the outer edge. It has a concave face to keep it centered on the clutch button. I measured .065 difference between center and outer edge.
The press fit seemed tricky to machine... starting at .277 and up to .3 over about a half an inch...... so we tried just putting 1/4" threads on instead.
Going to put it on and try it once things warm up outside!
