Hullwrecker™ 2roller Grain Mill w/ Base for Homebrewing ...
The old mill had a 3/8" output shaft. I used a 3/8" to 1/2" adapter to drive the sheave. The new mill was a step bigger than 3/8". It was 25/64". I had to drill out my old adapter to use with this new mill. Other than that it has been great. Also it had adjustments on both side of the roller. The Barely Crusher only had an adjustment for one side.
