Marker profile too big..

[Isky]

my guns way too huge with everything it has on it, makes me feal like i can go back to roman times and use it as a shield..i have a richochet, and a standard right feed which is like a foot right there..(kinda, not really..u get the idea ) then theres the gun, a psycho ballistics drop..the one without on/off, and a PMI 88/45. short of using a 4 oz tank off the back of my gun..i was wondering if i can cut the fee in half? its like 3 inches, but will it cause jams/breaks, anything like that? unloading just isnt my style..anyone who shoots at more than 8-9 BPS should be smacked i dont mind having this big 4$$ shield looking pb gun setup..im just tired of having the feed and hopper reach out like 11 inches.. btw, my friends gonna start making carbon fiber hoppers..anyone interested in the idea, email me at [email protected].. if theres enough ppl that want them at a good price, maybe he will make some x-tras?

as long as you have enough material to secure your elbow for your hopper you should be good. remember when cutting somthing up that you can always take more off later but never put it back after you've taken too much.

that said, i currently have the same body as you and i decided that i needed a slimmer profile to it...balance issues... so i took my hopper elbow and used it to mark a line one full width down on the tube to start with and hacked that off. tested the balance and height and decided that i needed a little more off...i've currently got it set up so that my feed tube is about an inch long and i have no problems with feeding at any rate of fire i can achieve. it has the added bonus of centering the weight of the gun a lot better.

good luck with the carbon fiber hoppers... its gonna be hella expensive from what i know about carbon fiber pricing

[Isky]

nah, my friends dad gets it for work in rolls. Its actually cheap as hell, i dont care what anyone sez, they are stocked up on this shizznit. Its cloth like, just gotta make it harden

The reason carbon fiber products are expensive is the labour involved in making a decent product. "Making it harden" takes a little more than a blue pill in this case.

A carbon fiber hopper will be VERY hard to create. And therefor VERY expensive. At least far more expensive than the injection molded plastic used in all mass produced hoppers.

Laying carbon fiber and epoxy (that's what makes it hard) in a mold is fairly easy if you only need one smooth surface. To get a smooth inside and outside as well as join the two halves of the hopper will be a challenge.

And finally, what would be the advantage of a carbon fiber hopper?

Maybe he wants to park his car on top of it.

I've used carbon fiber to make RC cars. The stuff is HORRIBLE for impact forces(like a paintball). Its real strong under compression, and you'd need to put many layers on top of layers to make it durable for a hit. Instead of making the hopper first, use the epoxy and make just a couple sheets thick in just a square. Then shoot it when its hard. It might take a day or two to get hard enough. See how it shatters? Yeah.... Not so good. Usually carbon fiber is used to lighten up things, what are you doing with it? If you can get it cheap(we get it free from NASA) why dont you make gear bag out of it.
Its also hard for Carbon fiber to do 90 degree bends. Its a fabric type material first, and to bend it, you first have to harden it, then break it on a line. This makes it weak, but its really the only way to get a good product. Maybe i'm just high, but you could maybe make the hopper out of it since you can get it so easily, and make a new style of mechanical hopper. Servos for RC cars would work for the motor in turning the fan blades inside. It'd be like a HALO TSA, in that you could program the blades to turn both ways. Servos go back and forth. But, i wouldnt know how to program it. Just with switches of some sort. Good luck.

Doubt you could make a carbon fibre hopper that would support a car. At least not without creating a huge hopper and spending a lot of time with a finite element analysis program to to get the right shape to deal with the stresses.

btw, theres two types of carbon fiber, woven which can only take stress in a certain direction, and molded..molded looks like any other plastic :P
NO PROGRAMS NECASSARY

Does molded come on rolls?

[Isky]

lol no..the stuff thats in rolls has to be hardened..when u look at these prices for CF, they are so damn expensive because the company CAN sell them at that price, CF is a cheap, weak, carpet like material until u MAKE something of it. woven carbon fiber is more diffucult to make...and can only take stress from certain angles. Molded can take less stress, but from every angle imaginable. woven can only make flat pieces, molded can be made into next to anything, as long as it doesnt snap.

I've been away for a week, so please forgive the late reply....

Carbon fibre is identical to fibreglass. For everything you need to know about how to handle and use it, go to your nearest autobody repair shop or automotive DIY supply store and talk to a knowledgeable sales clerk or read the instructions on the packages.

Making something with fibre reinforced plastic involves using the fibres and usually a two part epoxy. The fibres (glass, carbon, other) are available in woven cloth, random fibre mat, or in spools. Some fibres can be obtained 'loose'. Mostly that would apply to plant fibres and other miscellaneous fibres. I don't know if glass or carbon fibre is available this way, I really don't think so as both are very nasty fibres to handle and should be cut only when respirators or appropriate masks are used.

Creating finished product is the same regardless of what kind of fibre you use. All methods require at least a negative mold.

With mat or cloth, you begin by mixing the epoxy components (bonding agent and hardener) and colour (if any). The mat or cloth is then soaked with epoxy and placed in the mold. As the mold surface is covered, strengthening elements may be added between layers of fibre cloth/mat. If using cloth, the direction in which the cloth is laid is important if the part is to meet design requirements for strength. Layers of cloth can be laid in different directions to result in strength from all required directions. The epoxy can also be applied to the mold then followed by the cloth/mat and another application of epoxy. Care must be taken to ensure the epoxy is fully absorbed into the cloth/mat.

Spools of fibre (thread essentially), are used with spray equipment to 'shoot' fibre and epoxy onto the interior surface of a mold. The spray gun mixes the epoxy components and colour, chops the fibre thread into small pieces, and sprays the lot out.

These methods result in a smooth exterior surface (at least as smooth as the mold is) and a rough interior surface.

After being laid-up or shot, a plug mold could be employed to shape/smooth the interior surface.

When making small repairs, I have found that laying the cloth out on a plastic sheet then pouring the mixed epoxy over it is the best approach. Then you can manipulate the cloth to absorb the epoxy, and then lift/place the cloth without getting your hands covered in epoxy. Once in place, just leave it alone until the epoxy is set. the plastic can then be pulled off. If the plastic is pulled tight once the cloth in place, you get a perfectly smooth finished surface. The drawback is that painting, applying another layer of cloth, of applying putty/body filler requires the surface to be roughened. But that is easily done with a sander for paint, or a drill with a wire brush for more cloth or putty/filler.

ok two things you shouldactually make. a tank cover (i know wierd but it would be original) and a dropforward.

that would be just awesome.
