Hi. I have a dual blade mixer which I'm using on some silvercoat for the
roof. I've used that mixer one other time, 6 or 7 years ago when I did the
same thing. So I go to use it just now and the bottom of the 2 blades isn't
spinning while in the can. It appears to have become disengaged from the
shaft and spins freely when not in the can. The upper blade is rigidly
attached to the shaft.
Any way of tightening that blade? There is no nut on the bottom of the
shaft, as I've seen on some designs. The only other adjustable is the
slider that controls depth...but that doesn't tighten the blade.
