alternatively to save a little weight...

just drill a hole in each side at 90' degreee angles and stick the tubing through both(they havent come out of ours at 550rpm)

and to power it easily, if your using 4' PVC just screw a cleanout of the bottom and attach a 1' square tube to a motor and slide everything in place
