so i have the very basic (and poorly drawn, i might add) concept done.
Spoiler (click to show/hide)
just to clear things up, the thing on top is a gauge, the thing in the middle of the tank is a boiler plate and the thing under that is either a manufacturers label or a control board with lots of toggle switches. for the middle tank im using a 3 liter soda bottle
Spoiler (click to show/hide)
im not sure just yet what im going to use for the fuel canisters (probably smaller soda bottles) but for nozzles i was thinking about using the tops of these bike horns.
Spoiler (click to show/hide)
. thats all i have worked out so far, but im very serious about getting this done. i really need some help with this. herr doktor, im talking to you  Wink. if anyone has done something like this before i would really appreciate whatever you have to offer. if you think i should change something then let me know. hell, you can tell me it downright sucks as long as you offer some way to make it better  Grin.

... the thing in the middle of the tank is a boiler plate and the thing under that is either a manufacturers label or a control board with lots of toggle switches...

I think the concept looks fine, but I would go with a brass manufacturers label on the back. Toggle switches may look cool, but it wouldn't make sense to put important switches out of reach of the wearer...
For the fuel  tanks, you may want to look for some lightweight PVC pipe at the local Lowes or Home Depot. I know there is some thin walled pipe and this would allow you to get a good length without having to splice two soda bottles together.

egads! what was i thinking, putting controls out of reach? of course pvc was my first thought, but ive never used the stuff and was concerned about weight. i take it this isnt an issue?

p.s. if you couldnt tell, i am new to propmaking of this type.

I am not sure what it is called, but there is a very thin walled PVC pipe. I think the inside is black and the outside is white...

If you are worried about weight, find an old backpack frame or even a regular backpack and fill it with some weight... walk around for a while removing or adding weight until you find what you can tollerate. Once you figure out what you can comfortably carry for a suitable lenght of time, weight the backpack and use that as your target for the jetpack.

i must say i'm slightly dissapointed that it is just a prop.

edit: that sounded a little harsh, i know an actual working jetpack is probably beyond the skills of the majority of people here (me included)

I don't see why there wouldn't be a few switches and indicators on the device that aren't accessible to the wearer in flight.  My car has all sorts of knobs, caps, handles and latches I can't manipulate while I'm driving!  I could see such a device requiring the assistance of a technician to launch.  Once the pilot was strapped in, he or she might activate the main boiler, check the pressure (the gauge is on the back,) and once the device was found to be performing within acceptable threshholds, give the all clear to the pilot to take off.  Alternately, a pilot could do all those things himself before slipping into the harness.

As far as in-flight controls, what about running a plated wire from the main body with a controller on the end, and sewing or riveting a loop on your coat to hold it close to your chest, with the wire strung with just a little slack under one arm?  You could do a snap on one end that would let you pull it off your coat quickly, in case you needed to shrug out of it in a hurry.

If you do go with a soda bottle for the main body, you'll want to reinforce it with something.  The stress of bearing those tanks on either side are very likely to deform the bottle.  Alternatively you might be able to fill it with that pressurized insulation in a can, just to give it a little more rigidity without adding much weight.

Speaking of weight, if you wanted to stay cheap and light, Pringle's cans or tennis ball cans might serve for the fuel cannisters.  You'd have to reinforce those as well, but they'd be easy to work with.

thanks for the suggestions mr hatchett. but ive thrown everything out that i have so far. i dont know what i was thinking, maybe it was lack of sleep but i digress. i got the pvc for the two side tanks and am picking up the bigger for the middle tank later today. i looked all around my house today and found all manner of hoses and plates and all sorts of useful things.

ive just sculpted the nose cones for the fuel tanks, now all i have to is mold and cast them. i need to get my dremel back from my friend so i can simulate plating on the tanks, but that will have to wait. after theyre all plated, painted and riveted all ill have to do for them is figure out what im going to do with the bottom of them. i havent yet started work on the main body/combustion chamber, but i think i will be picking up the pvc for it later today. i imagine thats going to be really hard to do, but ill get to it when i get to it.


p.s. ive been racking my brain for a name, but cant come up with one. any ideas?

Ahaha, the first time I tried to phrase this it was "Are you planning on making a real jet pack?". So let's try again. Out of curiousity:
Are you planning on giving it any functional parts? Or is it all aesthetic?

Wasn't Hector the name of the computer that the Silastic Armor Fiends built? A great machine that could do anything asked of it? It failed to produce the "ultimate weapon" the first time,  but went to great lengths to complete the task... only to be finally destroyed by Trillian?

So if you do name it Hector, avoid women named Trillian...

the computer was actually named "Hactar" this silastic armorfiends or striterax asked it to build the ultimate weapon, it did, but with a flaw. the armorfiends beat it to a pulp and then hactar coerced the people of krikkit to want to to destroy the universe. sorry, im an even bigger fan   Wink

and Hactar (thanks for the correction) did build the bomb, put it in Arthur's pocket, and due to Arthur's horrendous cricket pitch, he saved the universe from total destruction...

Hmmm... let me think on it....  How big is the PVC for the tanks? For the mixer/thruster?
