Mr Crawley,

This cannon is rocking. Great design. Looks like it is very powerful at low pressure. I guess a piston will do that for you. Keep em coming, and you can put on a how to for the rest these slimy gits.

Nice job on the concept and design. Great idea. How long did it take to construct?

I like your trigger Idea. One question, Is there a spring on the trigger, and how does it reset itself?

This is great advise and it sounds as if you had a lot of trial and error. The best advise i can give is...A smart man learns from his mistakes, and an even smarter man learns from other's mistakes.

At my local hardware store, what department should I look to find it? What is its original intended use?

The silver gizzmo.

yes you can, as long as you use a regulator. 120 psi is the most I have ever pressured my cannon to.

The best silencing material is flame proof blanket material for children found at your local walmart store. To silence the barrel, you need to bore 1/4" holdes into the barrel itself, and then build a 3" pipe around your 1 1/2" barrel. pack the inside before you place on the outer reducer. The outer...

Nice cannon! What type of valve is that?

Yes you could. This would allow you to have a greater size tank, without the added weight to the cannon itself. That actually was my original design. Great idea.

As far as a regulator, you pick up a regulator from Home Depot for $19.00 us. I use that in conjunction with a ball valve to feed my chamber. (All of the fittings I use are in the compressor section of Home Depot.) That is filled from an air Chamber on the top. You can fill it throug the Shrader val...

What LOWES does is have a little book. When you bring back the old one, they then will issue you a card by scanning the book for around 19 dollars as a credit for the bottle. Then the cost of the 9 oz bottle is around 24 dollars. They apply the card to the amount for the new one with a difference of...

Oh,

Normal paintball tanks will work. However, in some cases you will need to buy an adapter which you can find at your local WalMart for around 25 dollars. However, Most tanks will work.

I have a Kobalt CO2 assembly which comes with a tire guage, safety glasses, connections, a spare tank which is redeemable at time of purchase, and the adapter/regulator/guage and attached it to my new T-Shirt cannon I am working on. I am using it in place of the fill tank on my current cannon. There...
