I have a coats 40 40 The changer seems to not want to spin the entire distance. I will help it with a pipe wrench to complete the rotation. The air pressure that it runs on is 125 psi. It is supplied with a 1/2 air hose with no restriction.
I just posted a video on you tube. Search. New way to fill air tank quick and easy. I just wanted to share it with you guys. It's great for the garage. Listed under themrhelperguy.
I guess this is not an original idea.
I have a brand new aluminum bodied power saw. Probably from the 50s or so. Can I ground the body of the saw or use a gfci to make this saw safe. I would hate to throw this out but I got shocked once buy an old aluminum bodied drill.
