probably should have shown right angle gear box that actuates valve on jack.
gearbox is the 90 degree box from the front of a burnt out 4 1/2" grinder-had to make a sleeve to go over the armature to convert to the vertical shaft. A spark plug socket wrench with built in universal (modified) connects the 5/8-11 threaded stub of grinder to valve on jack. This takes some real back yard ingenuity. (fun stuff)
