underhammer

[gunmaker]

Well here's something,  A while back on underhammer society page there was a pic & article about a 20 ga. pistol made by a "Correvon" Swiss about 1840.  Only 1 is known to exist.  In the article Roger Renner said might make perfect sense in a shotgun,  as it's double action just point & pull tgr.  as tgr does back hammer slips over hook on tgr....,Bang.  Great for follow thru in wing shooting. Not seeing the insides I made a paper pattern of what I thought might work.  Well it does.  This gun is a 20 bore X 26" bbl off ebay, lock & stock made by me.  Throws a nice pattern & 20 yd.  40 gr 3f equal shot & circle fly wads....If any budding gunmakers want to knock one out     fly at it............Tom  I'll answer any ? out there.  I really like this smoothie & carry it on treks hunts & walks.......

Pathfinder showed up at my door yesterday (11-16-'12) we had a nice visit I showed it to him & he got a big laugh out of it.  I think he liked it, ask him. Great meeting folks of like minded ML, wife & pathfinder really good folks...........Tom..........  most a you know that already....

Interesting action. It looks like you would have to cock it to re-engage the trigger after firing.
I hope you counted your silverware after Pathfinder left.

Very unique. I like it!

Tom,
You got a photo of the hammer at full cock?
My wife says I have no abstract reasoning ability, and in this case I must agree with her.  I just cannot imagine how that action works, no matter how much I look at it.  Another case of round shoulders and flat foreheads, me thinks.

Bigsmoke, Take both of your trigger fingers, make hooks of 'em.  Put 'em together, hook to hook.  Now pull 'em apart---keep 'em hooked,  see how the tips of your fingers slide up over each other ?  One finger is tgr. one is ham'r.....that help..........Tom

That's the most interesting thing I've seen since that caged honest lawyer I saw at a zoo when I was 12.

Honest lawyer ?? bet that drew a crowd.   Tried to count silverware after pathfinder vamoosed, but wife's brother having been here lately couldn't get a good count....oh well.............Tom

Really like that action. Makes sense any time you need to shoot fast. Defensive pistol or shotgun. Would be great for a trap or skeet gun.

That's what the Swiss gun was Ironhand, A 20 ga. pistol !

Interesting indeed...that Path took off when you started to count the silverware. Lucky for you he was with his lovely young bride.  That underhammer is unique.

Here's a link to a photo Renner showed a while back of another pistol. This one is also "double action." The ring trigger pulls the end of the spring/hammer down until the trigger slips the hammer free to slap the cap. One moving part and one spring. The "hammer" swings to the side to get it back into battery and to get the next cap fitted. I always thought this one would make a terrific shotgun action. I don't see how you could make an underhammer action simpler.

You have to scroll down about 3/4 of the way on the page to "Cooper, copy, or what?"

Very interesting concept , I,ve often wondered why the under hammers never caught on . Seems like a "back to the future " thing ? Not complicated enough to base arguments on (discussion) . "There it is , it works well ---now what ??
Nice work !

Thanks for the kind words.  Getting parts together for a 16 bore early flint fowler.  Will post some pic's as I go along...................Tom

Please do, Tom. I remember being a little fascinated by underhammers when I first saw one about 40 years ago. I resisted them as "not traditional." I've finally caved, and am building a 12ga with a Taylor action, Colerain Barrel, and some nice curly red maple I've hoarded. I also have an underhammer chunk gun and a RB bench rifle. I have a fantasy of a schuetzen rifle too. For me, it's a flinter, an underhammer, or a single shot breechloader. Somehow sidelock capguns just don't speak to me anymore.
