3/10/21: I watched several videos on YouTube about pneumatic cannons and found two key elements to protect our velocity is psi in the storage tank and how fast the valve can open. Tooth is a fact I intend to use an electric irrigation valve instead of a manually operated ball valve increase the speed at which it can open.
3/11/21: I've done more research into the irrigation valve and I have discovered that I may not even need to use the 24V AC solenoid to open the valve. I may be able to use a mechanical pressure release to open it. I intend to run this system by my dad who is a chemical engineer.
3/13/21: I have acquired all the parts that I will need for the air cannon however due to lack of availability instead of using a 4 inch piece of pipe for the tank I will instead be using 2 inch pipe.
3/14/21: I have run several tests to see if the solenoid it will open with 18 V DC instead of its intended 24 V AC and I am pleased to report that it indeed works. This should let me be able to fire the cannon without modifying the valve.
3/18/21: I have watched several videos explaining how to augment the air cannon to be more efficient via modifying the valve to release air from the top of the diaphragm more quickly. All of these would require drilling a hole in the top of the valve. I still have one big question regarding the cannon which is how am I going to fill it?
3/20/21: to incorporate some of the design elements shown in the videos that I watched. To the Senate and I have gone to a different store to procure pieces to create a manual valve opening release (Jumping straight to Tier three). Well I was there I have also procured a 4 inch pipe which I intend to use instead of my 2 inch pipe.
3/21/21: I have completed assembly of the pressure chamber and barrel. I have also started the construction of the manual valve release.
3/22/21: I have dry fitted all of the major components together and this is what it looks like:
3/23/21: I have applied thread lock tape onto the threads for the barrel the pressure container and the firing mechanism. However as As I was tightening the phone mechanism onto the valve the Apoxsee which held the fitting onto the irrigation valve Slipped and lost most of its structural integrity. I intend to fix this with MORE GLUE.
3/24/21: I have encountered several issues the first of which being that the Schrader valve which I use to pressurize the canon appears to not be working. Specifically it requires you to pressurize the interior of the other valve to 80 psi but before any air will get through. I'm not sure what's causing this and I have no clue how to fix it (I am willing to live with it however). The other issue is that while attempting to pressurize the tank I managed to snap the firing mechanism off. I intend to use a lot more glue and also rough up the surface of the valve when I re-glue it. However even with these setbacks I still have managed to pressurized the chamber and fire the cannon. IT'S AWESOME!
3/27/21: I have re-glued the fine mechanism and it is currently drying this time I was taking no chances either used a trimmed down paper towel tube To contain the glue and I used Play -Dough to stop the glue from leaking out.
3/28/21: Completed the first successful live firing tests and I think you should see for yourself:
