I have this Bosch drill that would solve your ground problem. It can drill a 1'' hole right into rock in minutes. Although with the lack of rain we have had, I almost need it here to put my run up stand in the ground. I made one from 3/4 '' copper pipe, 2 90* l and one T fitting. Caps on the top, and 3/4 pipe insulation for the cushion. When the ground is not so hard, I just step it right in, and stick the tail of the plane in it and ready to do what I want.<div></div><div>For an engine test stand though, I have some 1/2'' steel flat stock, and a 3/16'' plate with slots cut in it. I have the 1/2'' blocks bolted to the plate with carriage bolts so they adjust, and a pin on each block for the mounting hole in the motor, then a clamp that bolts the motor down. I need to find out where I put it, havent used it in years. It has a cable with a clevice on the end and a knob on the other, and it is secured to the plate, and a place to mount the tank with a strap to hold it down. The whole thing clamps to a workmate. </div>
