Here it is $65 with no controller or sound
It is made of 3/4" PVC and 1/2" pvc pistons OSH, I use a Prop 1($40) with sound card ($8). The pistons unscrew and I changed out the old 'O'ring with 2 new 'O' rings (13/16" I.D. x 3/32" wall OSH part # 0547) and vaseline for lubrication.

I want to see how the pistons were set up and the how to. Looks like a manic jack in the box!
Eventhough I am Dead it is always warm inside my bed.

The pistons are from OSH, used to fix PVC breaks easily and at $3 each instead
of $30 they seem to work fine as they only need to work for a few hours a year.
I did need to replace the 'O-ring and use Vaseline to lubricate and it uses
gravity to come down.
Making it with pvc is very strong , lightweight and water proof. It uses 25 lbs. of air pressure.
I will post some kind of a "how to" in a week or so.

Looks great! I have always been leary of using PVC for air, but it seems to work well for you..
For those that don't know, OSH is a west coast hardware store, short for Orchard Supply Hardware.Your resident Proptologist.
