Back in the workshop, msa bottle is toooo heavy to use as a scoop, nice try, if it did not have the aluminum liner in it it may work. So now im building 3 new scoops for Robrcer, Jaywxman and myself, aluminum, medium size, just drilled 86 1/2 inch holes, next to form it into a circle and then weld it. Im even gonna try to build my own roller tool, looks simple.
