Is there any particular reason you needed to make such a complicated breech?

It does not jam and it shotgun loads this way. If this breech is complicated and you guys can think of a simpler method then do it up and show the world. It would be a step forward. Lets see now, who is good at improving my work? Well there is this one character who thinks he can. Nah he probably cannot do it.

You're on. I mean that in an as friendly way as possible.

So, I was under the impression that a lot of people used these kinds of breeches. Apparently I was wrong. Angel would definitely know about them if that was the case. If, and only if, this isn't common practice, I'll name it the Tantum breech. But if not, then this is just another breech write-up. I'm not about to name something that everyone already uses. And it can shotgun load and it doesn't jam. Yay!

This is more of a collection of pictures then a write up, but I think its pretty self explanatory.

Breech View:



Barrel Sticky-Outy View:



The next part is of a second slot and a little plastic thingy I glued on to prevent the barrel from being able to be pulled out.

Not-Pull-Outable Mech View:



The next set of pics is of the flares that I put on the end of the 19/32 to allow shotgun loading and so the dart is pushed into the barrel as one closes the breech.

Flare View:



Now to answer some questions beforehand that I know will come up:

I'm using thinwall because you can't fit e-tap between regular 1/2" PVC and 19/32 brass. I know some just nest it directly, but there's still some wiggle room if you do it that way, and I'm obsessive compulsive about straight barrels, a la my longshot, if you saw it.

The coupler is there midway through because I didn't have a long enough piece of 1/2" thinwall.

What do y'all think? Especially you, Angel. Do you like it?

Reading this thread made me happy.

Moving on I cannot see how this breech would push a dart into the 9/16"
I can see it is possible that a dart might just fall through the other side.

I think a video demonstration might be in order.

I'll start a vid now, hopefully youtube won't be a bitch today.

I don't even flare out the back of my breeches and they work fine. I just put the dart in the slot, and close it.

[Zorns Lemma]

I can see it is possible that a dart might just fall through the other side.

Flaring the other side of the 19/32" means you have what amounts to a 19/32" sheath with a 17/32" or 1/2" end. Good dart fit in the 9/16" barrel material means that you will never push a dart through the 19/32" Poor dart fit means you'll encounter the same problems with a nested brass dart stop, except that perhaps it won't be as problematic, given that you have more room to work with.

[dizzyduck]

I made something like this too, except the bolt is on the breech door itself (because I was too lazy to dremel a bolt channel into the PVC). Mine uses 17/32" brass nested inside 9/16 nested inside PVC.

Quick Edit - I made it back when I was really stupid and before I figured out my foam doesn't fit 17/32.

Video will be up shortly. I hate the youtube uploader. They really need a progress bar.

[TantumBull]

Done uploading.

Demo Vid.

Edit: Apparently it isn't "processed" yet. It should be shortly. Apparently the one I uploaded last night is working. I changed the link to that one.

That's just a more complicated version of what I explained in Forsaken's thread. It is also more complicated than the breech on Forsaken's maxshot. What you have here is a nice design, but I wouldn't go around calling someone else's design complicated when yours is just as complicated because of the "can't pull it out too far" thing. Again, that is a good design, but it isn't simpler than Forsaken's. It does require less brass than his, so that could be a plus for some people as well.

I also recently realized that this type of breech is not very well known. I made a breech very similar to yours, only it was made of PVC and another plastic tubing which I found in a water gun. I was excited when I found there was an airtight seal between the two pipes. I will post pictures in a little bit.

In my opinion, its simpler solely because it doesn't require as may pieces as Forsaken's and its easier to understand (which is because it uses less brass). You could also just cut a bigger slot and adhere the nub to the barrel there, as dizzy explained. But yeah, I guess its mainly the less brass thing. I claimed its simpler becuase that's how I see it, and I think it is. Thanks for the feedback, though.

It's funny you say that. In my experience, a lot of the pumps in super soakers tend to have a perfect fit on CPVC.

I understand what you're saying. From my standpoint, I don't see it as simpler, but I can see how you would say that. If one were starting from scratch as far as materials go, though, yours would be cheaper. Both breeches are great though, and they function pretty much the same.

[TantumBull]

It remains in the 9/16 barrel, and moves with it. I forgot to add that in. It's another way of shotgunning darts if you don't mind opening and closing the breech a bunch of times.

Edited by TantumBull, 08 March 2009 - 04:05 PM.

[cheesypiza001]

Here is my breech that functions the same way Tantumbull's breech does.







The body of the breech (the white part) is 3/4 PVC. It is connected to the BBB via 3/4 endcap with a hole drilled in the end. I made this a little more than a year ago which was when I did not have any couplers. Unfortunately, I took this breech apart so I cannot take anymore pictures, however, I might be able to reassemble most of it.

[Forsaken angel24]

Good work! I see what you are talking about.

[BustaNinja]

I like it. I really don't get how these breeches are so complicated, mainly because I am use to working and planning stuff like this, but they just don't seem complicated. You have the barrel, and the sheath. The sheath has a cut out section to put the dart in, then you push the barrel over the dart.

Or, you make a cut in the barrel and sheath, and have a twist beech.

I am wondering that makes these so "complicated". Anyone care to explain where this complication comes from?

[slowguitarman]

The complicated comes from Angel's Countess thread. TB asked why Angel's breech was so complicated.

[boom]

Tantum your last two top ics in the homemades ahave been truly awsome.The deoderent clip was sweet.And once
I give up my fight against B.O. I'll try it.Please come up with more.

[BustaNinja]

No, I know about that, but where does the idea of any breech being complicated come from? Maybe its just firearm knowledge or just working with materials, but none of them are really that hard.

I honestly have no idea what you're trying to say. The talk of how how complicated a breech is came from TB's post. I don't think that any nerf breech is complicated, but TB thought angel's was too complicated, I guess.

[sputnik]

TantumBull, props for that.



I've been using this setup for quite some time now..






The "handle" is a 3/4 Sched. 80 tee insert, minimized slightly.

The barrel it is attached to is 9/16, which is the main barrel.

The barrel with the slot cut out is 19/32, protected by Sched. 40 electrical conduit piping.

At the back of the 19/32, there is half an inch of 17/32 brass covered by one half inch of 9/16 brass, (both crimped inward as TantumBull's were)



Illustrated via Paint:





It works really well.

[Shrub]

Ah I find that someone else uses this setup mine however uses 1" of 17/32 for a 9/16 breech or 1" of 1/2" for a 17/32 breech so the barrels lock in place then the peices are glued in each other and then glued in the sheath.

[TantumBull]

cheezypizza: Nice. I like the set-up.

Forsaken: Thanks, it means a lot.

Busta: I'm almost positive I already explained this and had a conversation about it with SGM. It appears you missed that post so I'll give you a quick re-cap. Basically, I found it used more things to get a job done that could be done in a different way that used less materials. Thus, his was, in a sense, more complicated then it needed to be. I sort of glanced over his breech description, not really trying to understand it, but saw that it needed more brass, so I deemed it more complex than necesarry. I just read it again and now I see how the other brass stubs push a dart into the tightening rings. And I've angel breeched a longshot, so please don't undermine my ability to understand breeches.

SGM: Thanks for helping to clarify.

Boom: Thanks a ton for the compliments, man. If you want me to make you one to sell to you at the SOF war, shoot me a PM. I can't sell online though, so you would NEED to be at the war. This is only if you don't want / can't make one yourself.

sputnik: Looks nice, man. Loving the handle.

LSW: Glad to see someone else makes these kinds of breaches.

Im not undermining anyones abilities to make breechs. They aren't difficult, and yeah, I honestly like yours alot more then Angel's, as it uses less brass, isn't overly complex and has a MUCH better system for keeping the barrel in the PVC then most I've build. I will probably have to adapt that design for the OfAllTheNerf's brass breech, as the brass used to do the same job is finikity at best.

Sorry if you took it that way. It wasn't meant to be undermining you or anyone. Just kinda trying to grasp how some people (mostly the noobs) see a breech and go "Wow, complex".

And I fully agree. Less brass=good. I would rather spend more time cutting and gluing then more money on extra brass.

Alrighty, thanks for the clarification, Busta. I actually didn't mention this but you might notice than in the "barrel view" pics there is a little piece of e-taped 19/32 brass sticking out. This breech actuall has two segements of 19/32. One segment is the said piece to center the barrel, and the other is the one with the actual breech slot. This eliminated the need to cut a second slot in the brass for that nub that holds the barrel in. Which, while I'm talking about it, was originally a priming handle that kept breaking at the connection point with the barrel. Now, since its so small and I'm not pulling on it, theres not enough leverage to rip it off. I'm sure I could just reinforce it with JB weld, but I honestly don't feel like it, and I don't mind pulling the barrel forward.
