airsoft howitzer wouldnt that be fun

[Shdsteel]

Anyone know where to get fairly large tires like in the video. ?

[Old Dog]

Might try some of the wrecking yards, a number of small cars for a number of years use smaller tires and wheels and in many front wheel drives there was a straight rear axel, if one is lucky enough, even one with a wishbone attached, double lucky

One never knows, maybe a wrecking yard would like to sponser a project like that, only two answers, Yes or No, sometimes it never hurts to ask...

Boat trailers ect also have small tires and straight axels, could be narrowed to width desired...

Even wheel barrow wheels from Home Depot or Lowes with straight pipe axel cut to width, there are many options...

Bed frame metal could make trail legs set up to spread apart as standard trail legs...

Sounds like a fun project, makes me want to add that kind of thing to my shoulder held air cannon, mine has a safety pop off valve at I believe 120psi, never ran it above 75psi however...

Only will be going to 80 on this one and besides,
It is quite heavy lol. What did you use to fill your cannon tank with? Do you just have a hand pump or a portable compressor?

A compressor and a high pressure air gun pump, sometimes I have used a portable air tank that holds 100psi, one gets diminishing returns as the tank pressure drops with each refill... I have some paintball valving that I have been looking at that would give me repeatability, just haven't gotten around to building it yet...

A valve regulated Scuba tank would be great, but I sold mine several years ago

I think a pre filled air tank would be best to fill the cannon each time. Considering there is a good amount of room on the frame.

Now does anyone know how to make a smoke grenade shell?

[ColdFire]

What ever company or person were to start selling these kinds of things would make a lot of money. I know I would buy one... eventualy

[Shdsteel]

As long as you know and have the skills to make it. I am willing to make one for anyone who pms me and
Tells me they will buy it. I will have to finish current one to show you(eta 2 weeks).

[Mooncruiser]

Might I suggest, go buy a 1/35 scale howitzer or field gun model kit and scale it from that.

Ye the hardest part though was the bent plate steel.

This is a neat thread... I was planning on building a little mortar replica that would shoot nerf pocket vortex footballs this summer, but my car got hit last friday at a gas station so I have more important projects to worry about...

I was looking at valves and the like the other day in Ace hardware and nothing is super expensive. Does anyone know about how long of a burst at what psi could launch one of those pocket vortex 100yds or so? I was just wondering if I used one of those paintball CO2 tanks how many shots I could get off with one tank. An RPG-7 replica would be super awesome in a milsim match.

[Shdsteel]

Um not sure exactly your asking. Are you saying how long to leave the valve Open for? And for the pocket rockets, 3/4 inch piping from the tank to the barrel should do it(as in 3/4" ball valve will be used).

[theFlyingTrumpet]

Sorta... To simplify it. How many 100yrd shots with those pocket nerfs could you get out of a CO2 paintball tank?

That's why you always wear your goggles.

I still have this if you guys are interested. I'm going to be building a new one soon, about to tear this one apart to salvage the parts, but if anyone is interested it's still available for a little while longer...
