As you can see the top of the tube is fairly simple. all you are going to have

After that per drill some holes for a couple of drywall screws. You will need the screws to anchor the inner - body from shooting up to high. Yes shooting is the right word to use because depending on how much air pressure you use the piston will shoot right up. I have found that about 25psi will do the job.
I used weed eater string to stop the inner tube from going to high. Tie it to the drywall screws at the top of the tube and at the junctions of the shoulders, one on each side.
