I've written up a parts list, including cost.

Part List

They're about $40 each to make, including hella expensive clear PVC.

Edit: Whoops, made a small error, it's correct now

Damn, 40 bucks including the super wide clear PVC? Great job on keeping costs so low. A non-transparent Snap version actually wouldn't even be that much cheaper, maybe 10 to 15 dollars depending on where you buy parts.

[TOTtomdora]

That's just awesome. However, I'd prefer to go the same way Kane did; seeing as how I'm probably never going to order from mcmaster.

Yeah, pretty much. Fuck, now I want to make a clear PumpSnap.

Want to order some stuff, and make one before Saturday?

I recommend against that. I'm sure you could make a catchplate trigger out of materials from a hardware store (Most carry aluminum, for example), and the clothespin / nail trigger is definitely out of it's element. There's a good reason for the +bow style trigger

I've actually been thinking about ways to make this work with the traditional clothespin trigger. Its not all the way thought out yet, but it should work. It also would only work in a bow setting. Once I get my paycheck, I'll start some testing and building.

[TantumBull]

Carbon also did recently make a crossbow Snap with a clothespin catch/trigger and it functioned fine. It wasn't pump action, but that wouldn't change that it was still catching under the tension of the bow arms. Granted, he may have had a bow with less draw force than yours, Kane.

[HasreadCoC]

If a name is still being debated over, might I suggest "R.A.P.E. Bow," short for "Really A Pump Action Bow,"
or else "Really Awesome Pump Action Bow"? Oh yeah, and then there's the part about what it does to all the poor little "chewrens" who get in it's way, either way I think the name would be a good fit.

Alphabetz. I know, it's hard.

Anyway, I think having an angled end on the back of the punger rod to move up the catch then snap down (not that I mean to pitch my own work, but the only thing that comes to mind is that it's similar to an RTP plunger rod). Should reduce mass and material cost, and possibly shipping cost.

No, shut up.

We've been calling it the PAC, but it does need a better name, other than stupid acronym. At least mine actually is one.

I was thinking about that in the beginning, but just did this instead. Might be a good way if you want to have it stock-less. The only problem I see, is the the catch, catch plate, and rear frame plate are the only thing keeping the plunger rod aligned. I mean, sure the string does align it somewhat, but it would be terrible if it got slightly misaligned while priming it, causing it to Effeminate fail. If you had another spacer between the PT and the slots, that would definitely work. However it might work if you didn't even have any thing to align it, I'm not sure.

Reducing plunger rod mass is great, but I've pretty much already achieved the ranges that I'm happy with.

It would only reduce cost by maybe .60 cents at most, and definitely not reduce shipping cost. You have to buy 1/2" nylon in 5 ft segments anyway.

The main difference between Kane's and Carbon's version (other than pump-action), is that Kane's version didn't use the traditional SNAP catch. Instead of catching on the front of the plunger head, it caught on the back of the plunger rod. If you did it the way Carbon did it, using this design, you'd have to have the trigger and handle up in the middle of the gun.

Like Kane said, there's a reason why I didn't use a SNAP catch.

Well, it would seem I have failed.

After the TornadoBow was dubbed The Impregnator, I feel that the Pump-Action Crossbow should be named The Sterilizer. Or maybe The Extractor.

To clarify, it's not just that I'm catching on the plunger rod--- It's that there's a lot of distance between plunger rod and the clothespin that wouldn't be there in a SNAP. It contributes to the ruinous trigger pull on mine, which is ruinous even when not primed.

Yeah...a clothespin trigger relies upon the catchface as much as the clothespin. Ya gotta do it like this.

Yes, it's done, and it works great.

Fancy names are stupid.

We should call this the Revolution Nerf Crossbow.

I think the most obvious choice would be the Dickbow.

Everytime I leave for an extended amount of time, I come back to shit like this.

Awesome. Much kudos.

Wouldn't there be a lot of friction on the string? Re-stringing it at a war would be a pain in the ass.
