Biohazard Build Log

Unread postAuthor: pat123 » Thu Apr 24, 2008 3:37 pm

I finally decided to post this gun. Me and drex built it.
I wasn't sure if a build log would go in the showcase or not so I put it here please move it if it is wrong.

specs:
about 600in3 chamber. (hopefully it will be 2400in3 by end of the summer and sch 160 pipe :twisted: )
10ft 1/2in barrell (may also use a 7ft 4in barrel)

I will update this as we go.

that's cool I like the logo why do you have a + instead of a tee I don't know what it is called.

You can tell how awesome a cannon is by the pressure used.

yeah, but if you ask me, its too much work when you would get close to the same results as far as ignition time...

Looks interesting, if rather mis-shapen. That biohazard symbol will look great if you redo the pain and put a glossy coat over it.

FEAR will remain the most powerful operational hybrid until some time next fall, as far as I know. The flow restrictions on this thing are just too limiting, and FEAR's 2" porting has 4 times the flow. FEAR also has a much better chamber configuration. Also, the small fact that FEAR has 2" x 600" barrel...

Better things are on the way, but as most of us who build on the monstrous scale know, better things require preliminary testing, or something is bound to go horribly wrong.

It's called a "cross" rather than a "Tee"
I was wondering the same thing myself about a week ago.

Looks like a nice tank.
If someone sees it they may think it's medical waste or something with that symbol but it's cool. 8)

So this is the gun with the extreme flow consriction
Have you played around with larger bores and heavier ammo on HGDT.
If not i would persuade you to because nothing says flow constriction clearer than this gun does.
I don't mean any insult, Im just pointing out what has probably already been mentioned in this thread.

Other than all that it looks pretty cool, and is a notably nice hybrid
