How about carbon-fibre(durable and lightweight) or fibre-glass(durable but not exactly the lightes material on earth)?

Delrin is not very shock reistant. It's decent, but nothing special.

yeah I heard of someone making a carbon fiber shell, and he said it was too prone to cracks etc. I thought that would be a sick idea too. I found this on docs website, pretty funny:

P.S. you really don't think that delrin would be any stronger then what they are using now?? Also it could be pretty cool to have some things milled into the side of the shell if it was made thick (I would sacrafise light weight for durability).

Delrin is not strong, it's actually pretty weak, the benefit to delrin is that it's self lubricating and lightweight compared to aluminum. If you want to build a strong shell you want graphite composites that Glocks are made from, but it would look ugly as sin.

There are a bunch of different kinds of plastics being used now. For example, the old Revvy shells were amazing, but ever since they switched to the newer version they are much more prone to breakage. The "old stuff" used was practicality indestructible.

It might be more shock resistant than some plastics we are currently using, but if it's still as thin as most modern hoppers are, I don't think it would hold up better by a large margin. You could make it thicker, like you said, but you might actually be able to save weight by using thin aluminium rather than thick plastic.

Has anyone seen an aluminum shell??

I have used TONS of old revys, and they steel feel cheap as hell. And it seemed like only the black shells were strong, all the clear and smoke ones I have used got brittle and the feedneck broke.

I would go with a graphite composite shell! If it's ugly you can just do what SPO does and cover the plastic with..... I think it's a car paint job?? Can't remember now, but the SPO shells look great.

For the feedneck weakness, what would you guy think of a metal feedneck that is also the bottom plate of the hopper. And the top is plastic to make it lighter?

when i say metal i say aluminum or something lighter.

I think that sounds like a great idea! Like how the jrny has the replaceable feedtube, but just make it out of aluminum....

Aluminum-alloy of some kind could possibly be used...But aluminum itself isn't all that sturdy either... It bends easily if it isn't "tampered" with :P

the delrin would be a problem because of the lubrication in it, meaning the balls would get lube on, which means bad accuracy, but the compositwe material would be goo, but heavy

Self Lubricating doesn't mean it has lube in it, it means the surface resists friction, there isn't oil made into the part.

The fix for most feed neck issues is just better design and engineering, the materials are strong enough but have to engineered better then what they have been.

The torque shells are very durable and light. They are made from ABS plastic that is also really easy to repair is there is a crack.

At that thickness, Delrin would be no different. Polycarbonate is more flexible than Delrin and not as easy to scratch.

fiberglass reinforce polycarbonate. like what is on the G36 but it would have to be black.

or polycarbonate with a nice coating and a thicker shell

Sorry to burst your bubble but my pulse totally freaking sucked. Probably one of the worst hoppers I have ever used. I had a smoke one with a black board (supposedly the better one...) Within weeks the plastic started to micro fracture because it seemed too brittle. It got to the point where I was afraid to even take it apart. I have seen about 10-15 with one of the tabs broken off on the side where you press in to release the motor assembly. It was a good concept but poorly implemented. Pretty disappointing for me..... I have 2 rf transmitters for the pulse if anyone is interested.

Yeah, im not sure. Im sure the companies that make the loaders want them to break to some degree, so you can buy another one. I could be wrong, maybe this is just overlooked

The classic clear gray nalgenes that were pretty unbreakable are made of polycarbonate. I don't know exactly which PC but you can't go wrong with Lexan or Macrolon. PC is usually pretty flexible when it's thin, but the cylinder shape really stiffens it up, so it could work as a hopper. To get it stiff enough I'm guessing it would have to be at least .1" thick so it would be on the heavier side.
You can get it hot and vacu-form it into shape, and it's really machinable too. Unfortunately a sheet of the raw Lexan/Macrolon is around $50

Nice! I would be willing to sacrifice some weight for reliability. It seems like empire is going with a more flexible material on the prophecy instead of the regular rigid material, what do people think of this?

PVC gets very brittle after being exposed to sunlight and other elements, i would see plexiglass or lexan being a good material.
In my opinion flexible is better than rigid as far as paintball goes. The reason many shells break is because they cannot absorb shock, hopefully if the shells are flexible they will be better at that.

carbon fiber would be easy to make all you need is a model to work off of

also kevlar degrade if unprotected from uv

I heard of someone trying to make a carbon fiber hopper and it kept cracking and wouldn't withstand paintball hits. Seems a bit odd considering how strong carbon fiber barrels are, but maybe it's hard to make it that shape.... Anyone have any experience with it?

I just know that its layered, has some resin shit that you ply with it, and its baked at 248 degrees faranheit, or something like that

reinforced as in added, not just applied to the outside, so it would be protected from the sun, not that i was being completely serious
