M1 Bazooka

Be very careful what effects charge you put into it and make sure the tube is a seemless one. There was a bloke from the WWII LHA who decided to put a 3g ally flash charge in his reproduction Panzerschreck. Put it on his shoulder, detonated the charge and it split right next to his head. A hole the size and shape of an american football. Deafened him and shocked him badly. The tube was seamed. Bangs in metal tubes are something to be very wary of. People have a habit of getting carried away and using the biggest charge they "think" they can get away with. I say "think", because they obviously don't, really. Stick to the tiniest effect you can, and test it away from yourself first

Thanks for the heads up, Ive been speaking to a guy who knows a lot about Pyros, I dont want the tube to go bang, meerly just puff smoke out of the front and back. It's likely to be something very small in yield, the tube will probably amplify the effect of the pyro anyway like you say.

Sorry to hear about that bloke's misfortune!

Thats the Tube I bought, can't tell from the pics whether its a 1 piece extrusion or rolled.

Its rolled and welded webby

Yeah thats what I was thinking, but a guy at work seems to think that ERW means extruded... smoke machine any1.... hehe

You're speaking to one now though the best bloke to talk to about it is PD on here. Send him a PM and you'll get the best advice you'll ever receive, trust me

Will do BaggyPants thanks (Didnt mean to reply to that as a PM I do apologise!

Attached below is my circuit diagram, I'm not electrical engineer, so if anybody knows better of how I could wire it, or whether anything is needed.

The aim is to have 1 trigger to set the smoke off in the tube, and a seperate trigger to activate the charge at the target. 2 options for the tiggering of the charge...
1) Have a pre-set firing position in the game (where the wires are already laid on the ground, shooter runs into poisiton, connects the wires to the bazooka whilst loader inserts the smoke round in the tube... fires the smoke, 1 second later fires the target charge)
2) Have a remote device on the bazooka, and on the target charge, 2nd trigger is pulled to actiavte the remote bang (would have to be in range/line of site etc)

Well, far be it for me to piss on chap's projects but...
Two concerns:
1) Practicality
This sort of thing has to to be set up within the context of a battle scenario and set pieces are difficult to orchestrate.
I would devise and test an IR sytem first before progressing further since in my experience they are shite in the situations we play under. Radio control works but it isn't line of sight. Laser might work. Get a system working first.
2) H&S
I wouldn't like to encourage players to cook up kit in the expectation they can bring them to games - they can't, at least not without lengthy consultation first (not that Webby would of course - just a general point). Anything electrically fired has the potential of injury - that wiring needs a double safety IMO so it can only be triggered once the loader and firer have released independent safeties.

Somewhere there is a vid of PD's bazooka/shrek blowing up a tank effect using a line wire carrying a rocket to an effect. Mighy cool but only works under strictly control show battle conditions, not a skirmish. We nearly set one up for the Eagles event but chickened out at the last moment, reasoning it was more trouble than it was worth!

Yup I understand, I was thinking about St. Lo for its use as a firing prop, replica for all other times.

Perhaps having a circuit swtich inbetween the tigger and the charge at the rear end of the tube, which the loader activates, I understand what you mean from a H&S perspective on that front.

Notes taken on board Chomley, I was going to test the pyro in the tube well before any construction work takes place, under supervision at an airsoft site, and at distance.

If it doesnt work, its only £20 for the tube

i dunno what you're planning on firing it at, though?

a tree, a bush, anything that will look cool!

Not sure about the legalities of launching a projectile, 130 psi on a tennis ball, causing a limping injury, im sure that's over the 328fps coversion whatsit

stupid wiki!

So if i make that 1, its the M1 bazooka... right,,

cool thanks! ammended

Can't remember where I saw it, but there is one out there that is a "bottle rocket" launcher.

Thanks PD!

Thanks mate, I'll have a look online!

OhhHHHHH Boy!

Test, Manned test and Combat test of the 'Tube' holding the pyro have had successful results!

Thanks to Tyreal for the Thermobarics
Thanks to Major for being the test dummy!

I think the 2nd picture is the result of the flash from the thermo offsetting the exposure on the camera, the flash looks to have engulfed Major, but was actually quite small!

Tube was a little warm, but not red hot. The nature of the thermobaric means the force goes out of each end of the tube, rather than against the walls of the tube. Going to make an inner barrel to hold the charge, and some bolts to go through the tube, so that plod is satisfied that it will not be able to launch anything.

Makes quite an impressive FWOOOOOM noise too, instead of BANG
