Cain Kamikazi: i know it was explained briefly, but i still don't understand how this works....
Steven Sparringa: You have the same voice as the armoured skeptic
Blackzhabant Sandoval: wonder if is powerfull enough to be use as a Bait Caster Cannon.?
Anthony Antonellis: what glue does he use to glue the brass air compressor tank valve
Cle Collins: This is an awesome cannon. The key items: #1 look inside the 3" pipe and make sure it is smooth. I got a rough piece. #2 The time consuming part will be the piston and its' seat (the end of the 2" barrel). These must be near perfect. The piston pieces need to be as parallel to each other as possible and the barrel must be cut near perfect. Once your piston is done, cut a piece of sandpaper to fit in it. Use a tiny drop of super glue to hold it to the piston, we will remove that later. Use the piston with the sandpaper and lap the end of the barrel. Mark the end of the barrel with a sharpy and start lapping carefully, lifting and looking at the sharpy mark. Once the mark is totally gone, you should be ok. Remove the paper with a little acetone. Now here is the tricky part. If your flat rubber packing is not very flexible, you will need to do the following. I took some 1/16" or near spongy tool drawer lining and cut that fit the piston. I then took some 1/32" flat rubber packing and glued that to the lining. I then glued that to the piston. Now, remember the drawer lining is porous so you must seal around the edge of the lining with super glue to keep the air from migrating under the seal and blowing out the rubber. One last thing. The less surface area on the seal at the end of the barrel, the better the seal will be. I used a regular old bastard metal file around the barrel to reduce the area in about half. Take your time.
Jordan Dureso: Jake t I do freak your mom
baxtergusdog: You have the best experiments! Have you ever launched Peeps with the coaxial piston valve? We want to do something with kids that is maybe not as strong, using Peeps to shoot or launch. Any ideas? The potato is a riot, but maybe too dangerous for younger kids?
myasadefa: This video shows how to make a potato gun.
Dr. Melon: your fingers are stubs...
Aidan Obee: How does the power of a coaxial piston cannon compare to a standard compressed air cannon of the same size?
David Collins: could you build this with a longer barrel. Im going to start this project soon and i need to know. thanx
Jordan Dureso: you sound like kipay
MattMonk: I want this guy to be in my group if the apocalypse happens.
Nancy Guarino: When I open the valve to fire the cannon all the air blows out the back. I could use some help.
Isaac Lemus: i hope this is not to much to ask is there anyway you can post a list on exactly what you need to make it please thank you
Вася Сорокин: она на вакуме я непонял
Jason Anthony: I want my 9 minutes back
myasadefa: I really like this
Aaron1998ish: Night, you may have abandoned this project, but what if you made a plug styled endcap thats springloaded and held with a sear, that way when you pull the trigger it allows the spring to pull out the plug which then allows the air to pass into the chamber, Id love to share my more advanced airgun ideas, some are super effective.. But my nazi gun law driven country wont let me shoot a spitball without being treated like osama binladin -.-
