Hello nerfers. I just bought a 3/4 inch ball valve to use on my hopper. The only problem with this is the torque. It takes a lot to open and close these things. So I was wondering, what do you do to lower the torque on these things?
By the way mods, feel free to move this if it isn't in the right place.

The RSCB/ Hopper Hybrid
29 December 2012 - 08:32 PM
While playing around with my new homemade AAbow with an rscb, I thought, how could I easily hopper this without a wye? I thought back to my previous attempts and thought I could do better. Then I looked over at my parts bin, and saw a peice of curving conduit pipe. I knew what I had to do. I now present... The RSCB/ Hopper hybrid. By the way, this could be a good option for people without access to pvc wyes.
First here is what you will be making:

What you need:
1/2 inch pvc( Length depends on how many darts you want to be able to hold but about 8 inches is good for a lot of darts)
1/2 inch cpvc( For barrel)
1 1/2 inch pvc Tee
1 1/2 inch pvc elbow
1 1/2 inch conduit curving pipe( I think its 45 degree)
1 1/2 inch pvc endcap
Ok first you are going to want to get your parts obviously. Then you want to put the tee and elbow like so:

Just like an rscb.
Then add the curving pipe like so:

It might be upside-down, but im sure you can figure it out,
Then you need to make the barrel. I would follow Captainslugs guide to making hoppers, just use his method for the barrel.

Then assemble and your done.

Conclusion:
This really surprised me when first used it, it fed just like a hopper. You may need to tip it down slightly every once in a while, but its not a big deal. The only downside i can think of with this is that It has a lot of deadspace like an rscb, but im sure with a good gun, everyone can get this to work. Also, you can tune this so the curving part is offset to the side so it doesn't impair aiming as much.
I sure hope this helps.
EDIT: After testing this design in a war (indoors) I found when I point this up it won't shoot. So It isn't as reliable as I thought. Although to fix that, you could get a check valve, and blow through the top if needed, but overall, this is just a prototype with a lot of work needed.

Range master Tank help
11 October 2012 - 09:19 PM
Im a new member here. I know i should make a writeup or something first, but i really need help.
Ive been trying to mod a buzz bee range master recently. I read the mod guides, and started on it. Something i didnt realize is that i cut the barrel to short. I was trying to make a cpvc breech. It wont seal anymore.
PIcs:

Sorry that they are linked. It says" You are not allowed to use that image extension on this board" I use photo bucket.
Anyways The white looking thing somehow seals with the tank. Any help is appreciated. Thanks
I will also post a writeup on the range master cpvc breech mod if I figure out the problem.
