Probably a better idea to allow everything to center itself instead of force it to be still. My wife needed the extra step to make the top crank accessible. We usually only do about 7 or 8 mediums. I have used my son's 18 frame from Mann Lake but then my stamina becomes the weak link in the operation. Now if someone had a larger, powered one they were looking to find a home for, I am sure my wife would approve.Crofter " I have the extractor lashed and chocked on a stand." I was "gifted" a 20 frame extractor. After one summer I mounted to each leg 3-wheel casters. THe casters sit on thick rubber pads ( dampers). I get to maximum RPM after 1 low RPM spin for 10 minutes. I can walk away and let the timer do it's thing.
