Im tired of using a drill and want to make brewing days more simple so I purchased a motor setup on AllAmericanAleWorks. For those who motorized your mills, have you had any issues with keyless shafts on your mill when you install the love joy couplings? My current mill shaft is keyless and I’m worried about just using a set screw on the flat part of the shaft. I’m willing to upgrade my mill with a keyed shaft if it truly is necessary. Anyone have an opinion?
