HV1 - Hopper Design




It's finally here! I have finally made an instructable for my HV1 design, well the hopper at least.
I was going to show you how to make the back, but it just sucks too much and loses all its
strength. I was also going to show how to create the base, but it's not really worth it, as anyone
could probably come up with a more piece efficient one.

BUT you can still use it as a pull-release, and I am planning a better design for that, so for now
this will do. The most important part is included - my revolutionary V-type hopper design.



Step 1: The Hopper Basics

Pretty Basic.

Step 2: Hopper Basics Continued

This is just an expansion of the last piece, not too difficult.
I added plenty of pictures so you can get every angle.

PS. There is supposed to be a grey rod on both sides of
the hopper, not just the one that I put.
(See image 7, the lower grey rod)

Step 3: Hopper Expantion

This step is pretty simple - just add the grey connectors to the green ones (except for the front and back ones). Then add the rods through them. To be honest it doesn't make a difference if you mix the order on whether the yellow or white rod goes on whatever side.

Step 4: Sealing

Sorry the pics are blurry...

Now this step is a little weird, but very much necessary for its functioning.
What you need to do for this one is you need to tape both sides (on both ends of the hopper too) with a small piece (shown in fig.1) in between. Be sure to leave the small gap on the bottom, this is for the bullet to come out (or for the other end for the firing pin to enter).

Step 5: Firing Pin Guide

This piece is made to feed the firing pin into the hopper. Once again should be very simple.

Step 6: Firing Pin Suspension

Now this part would be the "suspension". Fancy huh?

Now this piece really does help, so it really isn't for show.
What this does is is keeps the firing pin perfectly in line along the bottom of the barrel, to prevent it from lifting and jamming. Trust me, this really helps.

You should be able to figure it out from the pics, but let me know if you need any clarification.

Step 7: Nozzle

I called this a "nozzle" because it's not really a barrel. More of a cap.

Now this is the trickiest part I would say, but that's only because I messed up the order when I was doing it. If you look over each photo, figure out a better order of making it.

I would suggest adding the yellow rods and support part (image 1) after doing the two prongs (image 4) part. If you guys have any trouble, let me know - and sorry in advance.

The main purpose of this cap piece is to not only support the cover (next step), but also to support the taped piece from blowing outward to prevent jamming. It has happened several times before without it when I designed this gun.

Step 8: Cover / Lid

This is just to cover up the innards of the hopper, also to prevent rods flying up from recoil of any sort. To open it just flip both flaps upward.

You can use standard yellow connectors for the flaps, but I used the ones from the Big Ball Factory kit with the little ends sticking out, this makes it easy to open and close with one hand.

Step 9: Shield / Other

This is not needed, but still effective in battle.

Note I did not include the stand or even the joint in the design here, because I believe it would be better if someone started from scratch and made a better one. Let me know if you come up with a base, handle, or even the back part (firing pin) - all mods welcome, just let me know so I can check them out.

    ok i think i am misunderstanding what this is. when i heard HOPPER i was thinking its some sort of device that hops up and down or something. can i get a descriptions as to what exactly it is?

    full instructions I thought this was a little incomplete but I wasnt going to give you the lecture like the admin

    The only parts I left out were the stand (not needed) and the back part. The back part as showed is completely replaced with a simple pull-release - using a black (grey) rod as seen in most guns. I posted this as sort of an "Open Source" type of thing, free for modification. As for being complete - it has all the parts it needs to function, even if it isn't the original.

    umm, as displayed a pull-release. So you pull the firing pin back and release. This is the design for the hopper, any reloading mechanism isn't included. If you are asking if the bullet will automatically set up itself: yes, when you pull the pin back it will set in place.

    It's pretty basic really, it's a V-Type hopper design that can be moded to fit any (large) gun.

    Never. :) I created the "Suspension" unit on the bottom (step 6) to prevent any jamming. What it does simple is keeps the firing pin from lifting off the floor of the hopper - so the bullet doesn't get caught on the top of the hole (like missing the bullseye). Thus the revolutionary hopper! I will still be tweaking it a bit, but the concept will mostly stay the same.
