Well, I have embarked on another journey to yet another cannon, and because I now have a camera almost all to myself, I thought I would put this up here, seeing as I am spending lots of time waiting for my epoxy to dry.
Basically, I have found that my .177 Stick Gun has become one of my favorite Launchers. It is easy to fill, Easy to load, Easy to fire, and after firing through almost 5000 rounds has not even had a misfire.
I am basically constructing a new version of this cannon, but in a far more controlled matter. It is currently day 5 of my construction and you can see how far I have gotten. and now, "Where I am Now", A pictography:
The Parts Layout (bad Picture... sorry)
Barrel Support. This was constructed by moulding an epoxy "ring" and then chopping it down into two rounded sections, of which I then superglued back onto the barrelstock.
Piston. Instead of a Direct Moulding, I like to decrease the friction inside the piston area by making my piston out of brass tubing filled with epoxy. The piston will be polished before final insertion as to decrease friction even more.
Sealing Face. I have placed it inside the brass tubing to help protect against peeling due to the high velocity air blowing by it in the cannon. This piece of rubber is temporary, I am precision punching out a better piece that will fit perfectly in the tube.
From here, I have alot of work to do. I literally just poured the barrel end of the finalized cannon, and I am waiting for that to dry before I start my next set of experiments. My general Idea for this cannon is to end up looking as close to a muzzleloader as possible. I have a very nice piece of walnut that I am currently roughing out into a nice thumbhole stock, and I need some way of piloting and filling the cannon without removing it from the stock. I want the firing to be trigger-like, and the fill to preferably be at the very back of the cannon, in the form of a Schrader.
So basically, What would you all recommend for piloting this thing rifle-trigger style? And any suggestions on mounting the "cannon" to the stock firmly?

You may want to crop the picture to eliminate the name an age!
Looks good so far!

A strong way to mount the "cannon" to the stock is by soldering a some nuts to the underside of the cannon then drilling holes through the stock so you can put bolts through the underside of the stock and screw them into the cannon. This is very similar to the way my airsoft rifle is held together.

I think jook13 had the right idea, in terms of piloting and mounting.So basically, What would you all recommend for piloting this thing rifle-trigger style? And any suggestions on mounting the "cannon" to the stock firmly?

@VH:
Actually, hose clamps can make an excellent temporary connection, at least, while you're testing the gun.

Well, I'm at my uncles house celebrating turkey day, so as of now I have no further developments. but I do have another question:
I attached the sealing face to my piston last night, and it doesn't seal 100% when I blow in the back of the cannon (a little bit of air leaks out of the barrel). Will this go away at higher pressures or should I re-mould my piston?
epoxy cured perfectly on the top piece. I discovered that clear spray-on plasti-dip will function perfectly as a method for stopping the discoloring of copper and add a very nice aspect of "rough" to the barrel part, which will end up having a nice effect.
As for attaching the "cannon" to the stock, I think I am going to hammer out some sort of brass "clamp" that I can bolt down in 4 places inconspicuously.
