Firing main guns . Any one done it ?

Recommended Posts

Has any one fitted a oxygen / propane mix with an igniter to the main gun its something i want to do . 

any advice would be most welcome . all i have found out is 70mm id for the bore is optimum so i will have to make the main gun to soot this . but i dont see why you couldn't fit it to the standard 30mm on the gun . So im looking for advice were to get the parts from what you did how you did it . etc . some one must have done this before .

I’m not sure how you would fit a 70mm bore into a 30mm gun? Unless you mean to hind the 70mm diameter tube in the cabin/turret and have the noise and flame ported through the 30mm diameter of the barrel?

I spoke to Military  muckabouts and they said they have done it before on bigger tanks and they used a 70mm pipe to make a real big bang .  Im making  scorpion type gun any way so 70mm is fine by me but just wondering who if any one has this all ready done who could assist me in it .

For a DIY job, try googling diy propane bird scarer. Lots of tutorials and I dare say suppliers will come up.

Back in the days when Tilbury Fort was a good place for MV's they had a couple of 5.5 inch guns. For a pound or two you could fire the gun. This consisted of a shell casing bored out to take a 12 bore alarm blank loaded in the primer pocket. The grin on my son's face, he was about 5 at the time is something I won't forget. Made a very satifacroty bang.

5.5 doesn't have a cartridge case nor any way of firing one, you sure it wasn't a 25 pdr?

No it wasn't a 25 pounder. There were two 5.5 guns on disply at the time, though now you mention it it may have been a 3.7 AA or something similar.  This is twenty five years ago or so now. (Hell! Where does the time go?) At that time Tilbury was a place that welcomed MV's and WW2 shows.

Have a chat with these guys, they've recently converted the 37mm main gun on an M3 Stuart.

They wanted over 2.5K thats a way more then i want to spend to get a bang . nice bloke we had a good chat but this is a bit of fun and 2.5 K would buy a lot of stuff and for me at least is to much for a bang sound from the gun

cheapest way is a pyro plastic maroon which is ignited by two wires across a battery-but beware these are incredibly loud with an equally impressive flash and blast.

I see theatre maroons brings them up  pyro plastic maroon did'nt 

 

I think for the odd time they will be used this may be a good idea I can hook up a trigger to the in turret battery . Only 2 problems i can see. 1. they are not sold to the public. 2. i would have to make a very secure screw on end to gun turret side and something to hold it , god forbid it blow the back of and fire inside . Unless some how i could fit it right at the end with the wire going all the way down the barrel  sound better and look better as well that way . I think thats only safe way id be happy to use them if i could get 1 .
