My solution to a underhammer with a full stock

[jh45gun]

Ok I got Logan's book at the library I had to get it interlibrary loan and I copied some of the plans in the book. The problem I had was most were for guns made with recievers and every thing wound up too long and into the wrist by quite a way which I felt was no good. So I came up with this idea which is really borrowed from a Knight inline system in a way as it is a plunger in a tube powered by a coil spring. The nut on the plunger acts like a safety as if it is up towards the tube the gun will not fire as the plunger will not hit the nipple and cap. It also helps having it that postion while capping the rifle and getting rid of the spent cap. The hole will be covered with a brass cover of some sort I have not figured that out yet. The sear/trigger is not what I will be using but a mock up just so you can see what I have in mind. Lots of work to do on the stock yet and the sear trigger but I figured I would post these pics now so you guys can see what I came up with. I suppose a machinist could come up with a better looking system based on the same principle but since I am always low on funds and cannot afford a machinist to do anything I have to come up with what I can. Parts will be blackened so they are not shiney. I tried out the mock up and it does work fine and fires the cap no problem. Like I said lots of work to do yet. I also will come up with a trigger guard that will come from the back to protect the trigger assembly; Top Pic is shotgun bottom is rifle.

The hammer is spring loaded and vertical to the barrel, a rather unique style. When my book gets here, I will understand even more. Thanks for the pictures!

Yea it is different but like I said trying to find a way to use a full stock made it neccessary for this style at least for me as like I said every plan I have seen is for a gun with a reciever. The European style in Logans book with the long spring on the forarm would work good if you had a stock that gave you some room to mount it or if you had a side mounted ramrod. It may be different but as long as it goes bang reliably I will be happy. You will not find this in the book as I came up with it myself. Jim

Question? To harden the sears, after I heat them to the right colors and quench in oil is that satisfactory or is that too hard and then do I have to temper it and if I do what is the best method to temper? I have heard heat in oven and I have also heard heat with the torch again until the oil sizzles off. What do you guys do or think about it? Jim

My soulution was to make the trigger hammer and spring all mount on a 1/2 by 5 plate and screw into the bottom

Nice job. ALL the plans I found were too long and started to get back into the wrist as I see yours is a little but not nearly as far as the parts I had cut out did and I did not want to get into the wrist as I felt that is a critical area for weakness. I could be wrong on that but I have seen guns with cracked wrist so I was afraid to get in the that area at all, as the plans I seen would have to go too far into the wood unlike the trigger set up on a traditional set up. Did you find your plans some where or come up with them your self? I wanted to use coil springs for ease of availability so that is why I came up with the system I used. Still got some work to do on it to fine tune it and the trigger system along with the stock work. I picked up some scrap steel today to make the sear and trigger system, but still keeping my eyes out for something that I maybe can adapt that is close to what I need already with out having to cut it out of some plate.

MRW you made that one ? It would fool me for being a old one ,what holds the breech in )im trying to find out what a standing breech is ? Nice work! :front: :front:

A standing breech is just a little taller that a sitting one!

Yes made the whole thing from scratch except the barrel it is a $39.95 gunparts special. This was my first attempt at building one, the action is sort of my own design it has a hammer powered by the triggerguard spring made from a chevy rear leaf, a center tipping searbar held in place by a ballpoint pen spring and the trigger simply pushes down on the back of the sear to trip it. The rifle is sort of ugly but shoots well i have placed in several shoots with it even after in one the front sight got knocked off and I taped a bobby pin on the front of the barrel with electricians tape for a sight. I have made several traditionlists upset because the action is held into the stock with multi purpose screws although perfectly period correct for the time period it was made 1999.

Standing breech MUZ BLAST page 4 "underhammer guns" story, history,ect.(july 2001) some fine looking rifles made by Kendall, but the barrelmeets the wood and the hammer isnt a 1/4" away from the inside stock part of the hammer it is called a standing breech/smith patent Let me put it this way whats holding the dang barrel to the stock ???? the hammer is a 1/4" from the stock/ not even room for a tappered pin.

Kind of a ps to your last, your not kidding ? thats really well thought out, is the hammer hooked to the spring or just pushs off the trig guard? till I caught the stock line in front and above the hammer it looked like a old one to me again nice work. :front:

MRW,
I like your story and your gun!

My solution to a underhammer with a full stock.

Novel idea and nice rifle, but I wasn't aware the problem or question you solved even existed. :haha:

 

[MRW]

I got a little better at building these after a few years here is the last one I did

Not sure what you meant about a problem existing but there was for me as any plan I found I just could not seem to fit it into a full stock. I found a plan with coil springs in Logans book but even with a short hammer it extended back into the wrist too far which I felt may weaken it. This does look unconventional (Mine) but I do not plan on shooting it at any traditional shoots but to use it for hunting so I do not mind if it looks unconventional. Some of the European styles in Logan's book look unconventional too compared to what we are used to with the traditional looking H&A style. And considering they look unconventional compared to the typical side hammer guns of the period I guess unconventional at times may be ok. :thumbsup: Now I just have to come up with a better ( Nicer) trigger. Sear set up than my mockup. I did blacken the parts and that does look better once the stock is finished it should look ok though different. Jim
