inletting round barrels

[camerl2009]

so im getting a .410 flintlock going

but cants seem to find much for inletting round barrels

so how is it done 

my barrel is not here yet but its off a cooey single shot shotgun so it already has a little part of canada in it

Cam;  Same as an octo barrel. Use gouges and make some scrapers with the proper radius and go slow. Check okieboy's post on building s chunk gun. there is some info there on scrapers.  Good luck with your project.   Bob

Hey Cam,
It's easy, lay out your design. For the barrel channel you can use scrapers & chisels, OR you can rough it out with a router, and a 1/4 " router bit, rigt up the  center of the barrel channel to the breech position, and to the depth of the barrel. You then can off set to the left and right of the center line for the barrel walls, but only 1/8" deep. You can then use a rarius bit to finish, or use chisels for the same effect.
Good luck!

If you're a tool fanatic (like me) you can check out the Brownell's web site and see if they still offer their round channel scrapers.  Best way to describe them is they are sort of "spring" looking ... () and I think they may have more than one or two sizes.  This is just a suggestion, as I have never used them but have seen them in the Brownell's catalog.  Don't remember the pricing though.  If anybody on here has some experience with them Yall might want to chime in.

This is not just round, it's tapered too. Honestly, other than straight octagon barrels, I find the set up of trying to machine a barrel inlet far more time consuming than just running a channel up the centre and then doing the rest by hand.

You could make a tool like this one on your lathe (provided you have one )

This is a Dutch Army armourers inletting tool, from around 1830.

Here's a link to the tool that Glenn is talking about:

http://www.brownells.com/.aspx/pid=6796/Product/BARREL_BEDDING_TOOL

Measure the smallest part of your barrel and buy the corresponding tool. Lay your centerline and inlet with a chisel to start your barrel, then do the whole barrel with the tool. If the barrel is tapered, simply lay the lines and remove the excess wood carefully and slowly with the tool. Inletting black comes in handy. Be careful, this tool removes wood quickly.

Send it to one of the guys who specialize in barrel inletting.

[Dave Dolliver]

If you want to do it yourself:
1.  Locate the center line of the barrel in the lock side view and saw along this line.
2.  Place the barrel on the top of this surface on the vertical center line (I usually rout a small groove along the
       C.L. to hold the barrel) with the breech in the desired location.
3.  Carefully mark the outline of the barrel on the wood in the top view. I like to use a knife blade and square.
4.  Cut a cavity between these lines about 1/8" deep.
5.  These corners you have created are the oposite ends of a diameter of a circle equal to the barrel at this point.
6.  A square placed on these corners will indicate how deep to cut the groove with gouge or other cutting tool.
       Rotating the square as it sits at the same barrel location sweeps the complete barrel contour at that       
       station. (High school plane geometry theorem about the diameter of a circle.)   Finish up with scrapers and
       inletting black.

There is another tool used by old time pattern makers that is a small, wood block, plane.  The sole, or surface that rides on the surface to be cut, is not flat but is vee shaped to ride on the corners mentioned above.  The cutting blade is not very wide, maybe 1/4" at the most, and the cutting edge is located at the point of the vee.
The cutting edge would have a small radius.  A half round groove can be planed with this, using the corners to guide the stroke.

i have a drill press some chisels and rasps

the best i could is drill the channel to depth and chisel the rest out 

non of them fancy tools nor can i buy them

The plane Dave Dolliver mentioned is a core box plane. I recently made one since they are hard to find. They were used to make cores for casting. Since the "v" shape is at 90 degrees, as the width of the inlet narrows, the cut becomes more shallow. It makes a 1/2 round shape. It was used on the Woodwright's show when he was making an embroidery stand.

I use a drill press all the time when inletting tapered barrels. Measure a number of points along the barrel length, andmark them on the stock  and how deep ie half the width of the barrel [ I like to be able to trim a tad off the stock later to give me nice clean edges ]  Drill your stock with an appropriate drill alongthe centre line to the measured depths using your stop on the drill press. Then merrily chisel/ gouge out the middle connecting your drilled points. Once the initial channel is there, the barrel can be laid in part way, and the stock marked with the outline. I work from the centre out, so the edges are the last to be cut. Use a very sharp chisel, and use inletting black or soot to do the final fit. For round barrels or oct/round I used washers screwed on the end of a rod as scrapers [ they worked well enough] until I made myself a proper tool.
With sharp tools and time,it's not that difficult.....Unless the wood is uncooperative
