Here's my plans for compressed air bullet hits
Here's my plans for compressed air bullet hits- special effects and filmmaking
Sorry this post may be a bit long, but i wanted to share this with everybody.
I made this because i couldnt afford to by an air tank so i made a small one out of 20mm PVC pipe and got 2 20mm end caps and drilled holes in them big enough to screw in the barb fitting and to put in the tyre valve. I then glued the end caps onto the pipe with PVC cement. I used silicon tubeing from the hardware shop and i bought the smallest ball valve they had to this i added some more barb fittings for the pipe. How you pack the blood is up to you i used the way where you put the blood inside the tubing and have wads of paper to stop it spilling out. I only put about 60 p.s.i. in it as this works well and you can run it off of a 12 volt portable compresser.
If you have anymore questions ask. Any improvments tell me.

Hey good idea, I'm tring to get as many ideas for my webpage may i place this on mine it will have all credit to you.
Thanx

Shore can.
I have a couple of other things i want to build too (lights and stuff) as soon as they are made and i am satified with tem i will post those to.

Not bad for a lame aussie bastard(j/k). Really, that's pretty good. I also thought I should make my tiny little update now. I mentioned in my plans about using a one way valve so the hit can be held upside down. Well after looking at JASON S's plans I figured all you have to do is stuff a paper wad in the tube. I tested it and it works perfectly. Make sure the paper is thick enough so the blood won't run through. I use paper towels. Not much of an update but does solve a few problems. Big thanks to Jason s. And good work Dale.
Hey Dale, that's awesome! I have 2 questions, what's a barb fitting, and what do you mean you can run it off a 12v portable compresser?

movies wouldn't be movies without the SPECIAL EFFECTS!
i was playing with bullet hits (for the first time) yesterday and i used tp to stop the blood from flying out but when i shot it (with an air compressor @ 85 psi) The TP flew out! Should i use red paper or what?
Or maybey a piece of fake fleash over the hole. Hey i just thought of that. wouldn't derma wax or mortitian's wax work well to cover the hole?

using the air compresser is a little easier than pumping for five hours with a hand pump. From what i gather you place your pump in the tire valve and blast away till you get the right pressure (to find this use a tire gauge). set up your blood hit, and hit the valve when you need it.
gnewbee
I use cotten wool to stop the blood coming out, this soaks some blood in and if you put enough it wont come out.
Have you ever seen in a chemistry lab? The taps the busen burner pipes connect on have barbs, they start out narrow and gradually gets bigger, they have what looks like steps so the hose doesent come of that easy. Go to your local hardware store and ask them they should have some in the gas fitting section.
The portable compresser is just an emergancy compressor you can by for your car, so if its wheel goes flat you just plug it in and pump the wheel up. Once agian your hardware or an auto store should have one. Its small and doesnt put out a lot of compressed air but it does the job for this.The one i have has a pressure gauge on it to make it eaiser to know how much you put in.
hope that helps a bit more

Is it a manual or battery pump?

Runs off of your car battery.
I suppose you could use a manual pump but im too lazy so i use the electric pump.

I put it on my site. under bullet hits.

Hold up guys, Dale nice job but theres a couple of problems.
1- PVC fragments meaning if a PVC cap falls or is hit the wrong way it (and it does not have to be hit hard)it will come apart as soon has pressure is applied, the pressure can also expand any cracks in the cap leading to a very big malfunction.
Use metal pipe and reducing coupling's to fit the ends. (and use teflon tape)
2- you need a preesure gage.
Thats all.
Can you get me Steve Erwin's autograph?

I thought that might be a problem too, so i used pvc pipe rated for a lot of pressure, a lot more than i put in. Even so first time i tried it i only put in a small amount of air. Now i only put in about 40-60 psi. the way the tubeing is attached to the tank it comes off if there is too much pressure (at about 80 psi.). I guess i should have metioned this before. And i am always carful not to drop it. I stand by my design, i think its good and safe, but if people want to use it thats up to them, i am not at fault, the should use it at their own risk, and use it as i have said. I know you have been doing this a long time and i appreciate your comments. If they want to make it out of metal than the can, it would probaly cost the same anyway.
Who is Steve Erwin? You can have my autograph.
To Gnewbee:
Can you put a disclaimer on your site saying that whoever makes and uses it does so at their own risk, also suggest using metal pipe and reducing fittings instead.
I might even try it myself.
Sorry this was so long a post.
Thanks,
Dale Jenner
I'll work on the disclaimer
Gnewbee
Thanks man, the pvc pipe i used was high pressure used by drillers, when they drill for water, but still do like mike said and use steel pipe.
Dale Jenner
Gnewbee,
the paper flew out. Were you using my bullet hit plans? I tried it and because the air has to go up and out, the paper only goes up and not out.
Goremaster no i didn't use yours yet 'cause i didn't get my hands on duct tape yet. I use Ejjiet's method. I know yours wont fly out cause of the way it is set up. just playing with what i had.
Gnewbee
I thought that was what you used. I tried it and had the same problem. The reason I don't like his method is because it ends up looking like a thin stream of blood flying out rather than a burst of blood which creates the illusion of impact.
very true. I find EEJIT's method better for blood sparying between someones fingers when they get stabbed in the neck.
But hey i had to work with what i had
