Oh i love these puzzles. I think i have the answer. Wow when you say table saw i immediately imagine putting the stock on the table so that one of the 12" x 3" faces is on the table and i think that is the problem. I believe if you were to put one of the 12" x 1/2" faces on the table, tilt the blade...

Heimo is right. It just isn't worth working directly with the premixed gas. If you get some kind of static discharge it is game over for you. I would avoid this design and go for something with more safety in mind.

Every time i pressurize a cannon for the first time and gradually raise up the pressure wondering if i will hear "BOOM"

MythBusters refers to them as "What the hell are we doing" moments,

I also wouldn't be surprised if it still had to function as... well... a toaster. Assuming it has to fit inside a toaster you can get some pretty huge toasters out there.

Toast has a built in crumple zone that limits energy transfer. Good luck. Toast is not a solid projectile. Keep us posted. This is a really good point. To some extent an optimized system may not work as well as a less optimized system because of this crush factor. You are going to have to accelerat...

Yeah i have looked into them but they are even worse for this situation. I have to finish the CAD first before i eliminate any ideas. Thanks so much you have been really helpful.

I was thinking about using the MJVO-3 but for the design i am working on it would be in a horrible place as far as comfort goes so i was thinking if i used an electric 3 way i could then place the trigger switch anywhere really so it would be more comfortable. I am still a little bit on the fence. J...

That is what i thought thanks.

What do you think of this one. It is 1/4 inch so it should be fine for piloting a 1/2" QEV.

I have been looking at 3 way valves for a cannon i am planning out however i can not seem to figure out if i want a normally open or normally closed valve. I did some Google searches and came up with nothing helpful so i figured i would ask the experts. I was hoping to have it set up so that when th...

yeah sorry I thought that I've seen these in clippard catalogue 17 bar is a lot (usually stuff form other companies is rated to 10bar max) MJVO-3 valve is pretty much the best valve you can get... I've compared hundreds of data sheets and most 1/8" valves that I could find cost about 30-50 euro exc...

This is a really cool design. I do have one question though. What stops the ammo from falling into the second T when the piston pushes it forward?

~DK

Thanks for such a quick response that pretty much does it for this thread

Hey everybody i was planning on making a cloud bbmg and i have one question, when i slide the barrel into the area where the bb's are all contained does it matter if the end of the barrel is flush with the wall of the pipe or can it extrude into the bb containing area?

Thanks

The laser doesn't do Jack. It is totaly unrelated to the movement of the sling.... Maybe there is some way of actually linking the dot to the position of the pouch, relative to the handle.... Than it would at least have some function. Anyway..it's a cool accesoiry....maybe even cooler cause it's no...

i am a cyclist and i know that they sell a little device in bike shops that when you pop a tire on the road instead of carrying around a pump you just tank your CO2 and this little adaptor you then hit the button it pops the CO2 thingy and releases all of the CO2 into the tire filling it up. it may ...
