Double barrel flintlock shotgun project (updated 1/19/2019)
« on: January 13, 2019, 08:06:31 PM »
Been wanting to build a side by side for a long time.  Finally got started.  Got the breech plugs made, fit and installed and the tang rough milled out.  Hopefully today I will get the hooked breeches mated to the tang.  Then I need to ream and hone the chokes out of the bores so it can be loaded from the muzzle.  It is looking like I will have pretty close to equal amounts of time just building the barrel assembly as in stocking the gun.

Wow!, David - you have some hard work ahead!

How are those barrels joined?

 David - Whatcha using for barrels? I suspect i, and many others, will be asking more "whatcha" type questions. I am subscribed to this thread

Dave - did you take pictures of the fabrication of the breach plugs and barrel breach area - I find that to be the most interesting of the barrel build up. Looks like you did a nice job of it.

Looking forward to it, and it's a long term goal of mine to build one also.

Taylor,
I will keep you guys posted on the progress, as long as you have patience.  I have an Isaac Haines I am finishing up for a customer, an Allentown that I am inletting the barrel, drilling the ramrod, inletting the lock and triggers and band saw profiling the stock for a client and a broken wrist repair for someone else.  Once these projects are out of the way the side by side will start to move right along.  I wanted to build and inlet the barrels just to get that chore out of the way.

Tom,
I had a set of modern 20g barrels made in Spain that I started with.

Paul,
I will post some pictures of the fixture I made to hold the breech plugs as well as the breech plugs.  I have to pull the plugs a few more times to ream and hone the choke out of the muzzle as well as finish drilling the powder chamber holes to the correct depth once I locate the touch holes and then to case color harden.  I will be breeching up a couple more sets of barrels in a couple of months and will document the process in more detail.  This first set was a lot of seat of the pants engineering.

Ed,
I should get more proficient at doing this as I have a couple more sets of double barrels I have been collecting that I plan on breeching and possibly putting up for sale.

Good luck! I built 5 of those and swore them off for ever. I'm sure yours will be a dandy. Don't sell it, you'll regret it for ever.

Dave,

You have just proved you are smarter than I am!  My flintlock double is a French gun made with two barrels I got from Robert Hoyt.  It took me 5 tries to get the barrels soldered together right!

I got delayed for a year by other things in life but I am now finding the time to continue the project.  I am almost ready to start the carving and engraving so you will probably be done with yours before I am done with mine.

Doubles are a "challenge".

Have fun!

Best Regards,

JMC

I have a set of old barrels that were given to me by a shooting buddy...and a good friend with a full-blown CNC machine shop...you really shouldn't be giving me ideas like this...

Now, the wheels are spinning...I just hope the hamster hasn't died...

   Did you cut those barrels off above the forcing cones or did you make some plugs to fit the cones???

Jerry,
I reamed the taper out of the forcing cones and then threaded the chambers with a taper tap and finished threading them with a modified bottoming tap. This gave me the slightest shoulder to seat the breech plug face on.

Got to spend some time on the double barrel today.  I was able to install the tang onto the hooked breeches and rough file the tang. I also installed an extension on my reamer and built a guide so I can remove the chokes so the barrels can be loaded from the muzzle.  I have my hones standing by after the reaming is complete.  Hoping to get the barrels inlet this week but I have 7 to do for clients.

Looks great. Did you make the standing breech? If so, from what?

David,
 In my experience, after you ream the choke out the reamer finish may be fine, a mirror finish isn't needed for a shotgun to shoot excellent patterns. Lowell Tennyson leaves a lot of machine marks in his jug and they shoot fine. Of course some folks just can't live with machine marks....so expect you'll hone yours out anyway. ;)
 I used to make my standing breeches out of ginormous angle iron. Cut it out with a freakin' hacksaw. Good Lord I'm starting to have waking nightmares just thinking about it. :o  I'm glad I quit making those things, everything about them is pure drudgery.

 You go ahead and have fun, I'll watch! ;D

Rolf,
Because I have a milling machine in my shop I was able to mill the standing breech out of a piece of 1018 bar stock.
