One of the things I hate is shaking spray paint cans when I am finishing a rocket. I am not interested in getting a paint gun and thinning paint, cleaning, etc. So I end up stuck using spray paint cans.
The mixer is designed to hold spray paints cans securely while they are shaken by a variable-speed (important), reciprocating saw ( Sawzall ). It is made of plastic with rubber straps and plastic connectors. The connection to the saw is aluminum.
The mixer is attached to the saw just like you would install a saw blade. You place the spray can into the cradle and tighten the strap down on it. Once everything is tightened down, run the saw at a very low rate of speed. Twenty or thirty seconds at low speed is all that is needed. The can is now ready for use. Do not run this at a high rate of speed — you have been warned.
