So while looking around for ideas I Realized something...

As for piloting, what if I used a presta valve as a fill valve AND a pilot valve?

For example, Look at this muzzleloader: Image

A hammer mechanism as shown in Maverick's Hammer Design could easily be implemented into a large wooden stock. I have constructed such a mechanism before for my .177 stick gun (it was far too large, as I intended it to be pistol sized) so it would not be so terribly hard to up-size it for a rifle like design.

If this seems phesable I just might do it. It would add a level of realism that I believe is untouched at spudfiles...

UPDATE: I have gone down the presta valve route. The epoxy has finally set, I have pressurized it to about 80 PSI, and so far I have no leaks whatsoever. Anyway, Below are some pictures of the final product next to its older (but smaller) brother, the .177 stick gun.

Image
The Woodstock's Barrel assembly next to the .177 stick gun (.177 stick gun is the not-shiny one). Ill admit it doesn't look very spectacular....

Image
Presta Pilot. Thankfully, I got this one straight, Unlike the .177 stick gun. As you can see, The presta is literally perfect for this application. It introduces a hammer-valve like opening style, and a little nut that can be used as a saftey.

Image
Barrel Recess. Nothing terribly spectacular, but I am quite proud of how clean it looks

Image
Shock pump fill adapter: A presta to shrader adapter epoxied into a female 1/4 QDC.

I also Got work started on my stock. Wish me luck.

Coming along nicely, I would get it to a firing stage before proceeding with the stock though. It will inspire you to get it finished ;)

funny you say that. Its late now, but I will have a damage video up in the morning (just a short one). From my preliminary tests, at 1/2 it's designed operating pressure it outperforms my multi-pump air rifle, embedding a .177 BB an extra 3 or 4 millimeters than my air rifle can. that and It had some kick, which was surprising....

:oops: double post again... It makes a little more sense to me though, seeing as there is no update signaled when I just edit my last post. If mods dont agree I will happily just edit the post.

Anyway, After a long, troublesome week of school I finally got around to carving out my stock. I'll let the picture speak for itself:

Image

I have also added an area to add in my hammer valve setup:

Nice job on the stock, how long did it take?

all of today... haha. I did it all with a rasp, pull knife and chisel. Hand tools make things take a while....

Anyway, I have a video here comparing the power of the barrel portion of this gun to my 66 power-master air rifle. I must say, It's mildly impressive.

That stock is super sexy vh man i really cant wait to see what it looks like when the gun is finished and stained. one question, that barrel looks a little short, are you gonna make an extension of some sort?

And a scope if its accurate enough would propably make it really hard to tell that it was homemade. Over all i can say that this is going to turn out really nice keep it up. One more thing, can you posts some pics of that gun rack in the background i wanna see it in all its glory. from what i can tell it has janet, mike and i think el bambino on it, correct me if im wrong.

Yup, you got all the guns right. Its just one of those perforated tool boards I screwed to the wall. Works like a charm.

And the barrel is intentionally short. I wanted this to feel "carbine" like. I'm thinking to shorten the forearm a little bit to give the illusion of a slightly longer barrel, But that's really it.

That and I don't think I will be putting a scope on this one. All my guns have scopes. It's time I invested my time in some nice iron sites.

Wow, this gun is coming along nicely. the stock looks super shooth and very nice overall!

I have constructed such a mechanism before for my .177 stick gun (it was far too large, as I intended it to be pistol sized) so it would not be so terribly hard to up-size it for a rifle like design.
Wow, someone actually linked to one of my topics? I'm honored! :D

Lovely job on that stock, my only gripe is the forend that comes up a little sharply - it would have looked better with a bit of a schnabel shape.

Still, don't mind my nitpicking, can't wait to see it finished :) and the power is impressive too, for all that pumping... just needed to stick the Benny Hill theme there hehe

Well that was quite a lovely surprise!

It has been almost 2 months since I have posted here and almost 5 weeks since I have even visited. School takes so much more out of life nowadays...

Anyway, that is a very beautiful stock and a super clean looking gun. I am really impressed with how you fit everything inside the chamber. I in fact, I have been thinking about a simple looking and very realistic smallbore to use with airsoft bbs battle reenactments. This may just be the inspiration I need to get one made over Christmas break.

I also like the piston design. I have had trouble with small bores in the past because they cut up the piston head, and this seems to have solved the problem.

Would you mind posting some more results from your test fires? Pressures used and damage pics with household items or simple 2X4/plywood targets would be great!

Lastly, I do have a concern. Once the hammer is in place, would it not impede the user's ability to attach a pump? how would you go about filling the chamber?

Great job again,

The Ever-Watching, Deathofall

When the hammer is cocked, there (should) be enough room to fit my adapter and the Quick Disconnect. If not... well.... Ill make it work.
