Back to Basics and Needing Ideas

Unread postAuthor: TwitchTheAussie » Thu Nov 15, 2007 2:27 am

Well I thought it bout time to pull my finger out now I got a job and build a new combustion. However I was too spoiled for choice at what to do and what dimensions to use so heres my gift to the site. Give me any ideas for a combustion and Ill see how many I can incorporate into my gun. The only rules are no use of metal or stun guns. Anything else is cool. Have fun kiddies :P

Edit: A quick Pic and sorry didnt do the 7

Revolving ammo holder and any help on quick refill and venting is appreciated.

Hmmmm, lets see now. I would go for a 12.7mm combustion with a barrel length of approx 1.5 meters. For the chamber it would be around 60mm od by 200mm long. Multiple sparks and a chamber fan and don't forget the silencer. BBq ignition.
You will be surprised by the power.
:twisted:
A nice stock and paintjob is a must also :P
Good luck Twitch :)

Metered butane. Dual ignition. Automatic venting and mixing via 555 circuit, solenoid valve, (with HPA tank), and small fan.

Also, one of those stocks from Jurassic Park I would kick ass. Just make yours silent so the raptors don't kill you when you fold it out. :P

Red-dot holographic sight wouldn't go amiss either, especially if you rifle the barrel, (accurately).

But, if you're lacking on funds... save your money! :twisted:

Also, don't go out on your own; have at least three mates in stab proof clothing, without any exposed flesh; use a reliable automatic shotgun, loaded with at least 00 buck; put enough rounds into it so you can be sure it's dead; carry lots of spare ammo; remember that cold blooded creatures do not show up on infrared; don't leaved any angle exposed and stay in open spaces; lock the doors so they can't open them; don't go to the loo in a crisis situation; get off the electric fence when it starts beeping; stay with the car; objects in the rear view mirror may appear closer than they are; and be the very well paid romantic lead.

But most importantly: Don't use a security system with gaping holes like the fact that the fences can be turned off, and are then useless (seriously, use a welded cross grille made from at least 2" steel bar, with a finer mesh across all of it as well)

Seriously, I should have designed the park:

A: "Oh bother, the power's gone, but the backup generator's already taken over. I'm setting the second back up to ready mode as well just in case the first one should go."
B: "Well, that's a little annoying, but at least all of the dinosaurs are firmly held in the solid steel cages that they'd need an angle grinder to get through. And they're electrified AS WELL! Imagine if we'd just used electric fences, and no backup genny!"
C: "Yes, it's laughable - we'd have a 3 figure body count by now, and it only went out 15 seconds back. And of course, to be extra careful, all the angle grinders on the island are locked up safely where not even the velociraptors carefully bred to be incapable of operating doors or machinery could possibly find and operate them."
B: "And our emergency breakers are NOT positioned in a forest where we could be ambushed when we tried to get to them".
D: "It should also be noted we have two fully trained and armed response teams as well should a problem occur. They know not to go out alone, and they stay in constant radio contact with each other and security central at all times."
A: "And the doors all have electronic safeguards that can only be opened by someone with a body temperature sufficiently high."
C: "All the staff were security checked, and the cameras in cold storage cannot be deactivated by any means. All the site is covered by cameras, and constant checks are carried out to ensure all dinosaurs are present in their cages."
D: "And all the creatures have been physically neutered, rather than just being made of one sex. And they are all implanted with remote sedation devices that we can use to knock them all out in under 10 seconds."
B: "But imagine what could have happened if we'd made those stupid mistakes... I mean, we'd all be dead by the time anyone was rescued."
A: "I know, but here, the tourists barely noticed. I'll fill out this short incident report and have the main generators - which are not in a remote location, it should be said - checked, repaired and restarted ASAP."

They have the same problem on sci-fi shows. Put the prisoner in a cell with a containment field for the door, which costs more, and then fails when the power goes.
Just using a regular solid door would be far more effective. I mean, we today don't get mass prison breakouts if the power should blip for a second.

Those survival tips should help you get through your problem with rampaging dinosaurs. If you are really worried, don't go near the island that they are on.

And now I've forgotten my suggestion...

Oh my god... Ragnarok... That post deserves some kind of trophy. I thought the mention of the word "raptors" would send some people off topic, but... just wow.

If I had photoshop on this computer I'd make you something :)

Anyway, the cannon should be partially clear and have a lighted fan.
