Big Assed Mother Farker

Unread postAuthor: striker » Sun Feb 03, 2013 2:30 am

as you would have probably seen in the hybrid build section that I've had this build on the cards for a few years. well I got around to making it a reality.
Its a 5m long 75mm bore hybrid utilising a class 150 4 bolt flange as a burst dics holder.
the chamber is a 20litre ex-oxygen bottle, and has a single spark plug and a single fill port, I dont currently have any close up pics.
the gun holder is currently temporary and as I get around to it Ill build a nicer setup (tilt and pan)

well here is a pic of the beast

and here is a vid of it as well

Im currently having to rethink my projectile choice, I was firing tin cans filed with concrete, but they seem to be getting the concrete crushed/broken up before it leaves the barrel, Im going to give shaped pykrete a go when I get the chance

Ah, finally! Given what I presume is the significant weight of the carriage, the recoil is pretty impressive! What mix was that shot?

Certainly this beast deserves some "proper" ammunition.

How about some massive airgun pellets :D from another post:

Not meant to be fired from spudguns though:

Pretty good effect on target:

Yeah the trailer is about 350+ kg and the cannon is 150kg (frame included)
the wheels were chocked and I didnt take notes but I think that was a 6 power mix, It started raining too hard for the cameras for the 9 and 10 IIRC

Im looking in to getting a lathed apfsds round made, maybe lol. next time is range testing :lol:

That's a BEAST :D

uhmm it's 75mm bore - one could fit lots of different stuff in the projectile - for example a mobile phone :idea:
