[img]/forums/images/icons/tongue.gif[/img] Not too long ago my neighbor and I were struggling to get some badly corroded bolts out of a corn planter using an air impact wrench. Of course we were working outdoors and the length of air hose needed to reach was considerable. His compressor has a big reel of hose on it all the time so wether we are near or far doesn't matter, the air still has a long way to go, and that reduces the pressure to the impact wrench. Sooooo.... just recently I made an "Air Boost" setup that enhances the air supply to the impact wrench. Basically the Air Boost is a nine-gallon portable tank and an air "Wye fitting". The wye fitting has a 3/8" outlet and two 1/4" inlets. There is ten feet of 3/8" hose that feeds the impact gun from the wye fitting. The wye fitting is fed by the portable tank and the hose from the compressor. So I hook it all up and wait till the compressor has completely charged the portable tank, and when that has occurred, I can go to work. The air supply is now coming from two sources and friction losses are reduced. For the first half minute or so I have tons of power from that impact tool as both air sources team up and feed that WYE fitting. Then I wait till the portable tank recovers and do it all over again.
