Title: Swivel Breech guns?
Post by: Tenn Hills Guy on August 02, 2008, 03:51:07 AM
Or, my preference is 'Turn-over' guns.  Somehow that term seems more in keeping with the era.   Being new here, perhaps they have been discussed 'Ad naseum', but there's always us new guys.  Dpharris has got a big bore beauty going I'd like to see some more close-ups of.  I'm building one from Dave Waters' book which will be smallish, 13/16th's barrels, only the hammer, frizzens and pans are store nought from DGW, the rest I'm doing from scratch.   There are probably a number of ways of building them and would love to see some examples and share some of the unique  techniques in building one.

Tenn,
It looks like you have a plan, and a good start.
I'd think that 13/16 barrels would be about right to keep the weight from becoming excessive on a swivel, espicially if you taper them. I have a late percussion swivel with straight 1 1/8 barrels and it weighs a ton! On the other hand, I looked at a Adam Angstatt with slender tapered barrels, and it was as light as a feather.
Are you going to use a modern swivel/lockup arrangement and barrel attachment like David Price uses, or a more traditional method? I can see where both styles have their merits.
Early wood forearm, or later brass one?
The only advice I can give is to think Slender (top to bottom) regarding the lock, particularly the forward part with the pan and frizzen.
If I was ever going to build a gun, it'd probably be a swivel breech too.
John

Exactly why I wanted to put this thread up, hoping to learn what obviously are a number of ways to build one.  Mine will use a lever and what the desigber, Dave Waters, calls a 'shot pin'.  Lever works an 'L' shaped gizmo which retracts the pin and allows the barrels to 'turn-over'.  I will use a wood forearm.  Never saw one in brass.  Just getting started on the stock

Yea, I've been to your site.  I don't like it! I don't like your shop! I don't like you!  Actually, I have had it book marked for awhile.  Frankly, that's what got me interested in them-SB's- in the first place.  Problem is, I can't seem to get past so much 'eye candy', I didn't reach the innards 'til today.  Guess we can't explain what  gets our attention.  Don't think I have enough years left in me to ever achieve what you do, but it's been a lot of fun doing the first one-kinda like your first ....... date? Thanks for the offer, you may indeed hear from me.

Hey Tenn Hills Guy, here is a brass forearmed swivel breech they had at Dixon's.

Those are nice, I especially like those gently curving stocks.

Seeing the swivel breech guns at Dixon's was a real treat!  I'd like to build one someday... well, I'd like to build one of everything, but a swivel breech is high on the list.  Several of the rifles had skinny 3/4" barrels if I recall correctly, and some are a lot slimmer than the photos appear.  There was an early Berks co. gun at the top of the case that also had 3/4" barrels in roughly 50cal (both smooth, mighta been bored out though).  A lot of those have a neat "sliding triggerguard" setup that releases the barrels.  Half, or in some cases the whole triggerguard slides back about 3/16".   It looks like you're off to a great start, keep us updated,

Nicolas Hawk, the top rifle in the picture, used a sliding trigger guard.
Pulling the TG back with your finger around the front bow, pulls the entire TG back, which pulls a pin back that fits into a detent (hole) in the swivel plate that the barrels are attached too. As you turn the barrels, releasing the TG allows a spring to slide it forward again, and as the bottom barrel reaches the top position, the pin pops back into a detent to align that barrel.
Viola! Ready for the second shot!

Wish I could get pics of the various types of construction, mine uses a lever to pull back the pin, allowing the swiveling and releasing then locks it.  I'm amazed at how small the action has turned out.  I will be using 13/16th's barrels.  I'm at the point know where a lot of little stuff needs doing: spring making, countersinking, grinding, polishing, stock work.  I made the 'universal double set triggers' for it. Started with a single set, but decided most seem to have doubles.
