What is a good method to straighten a 24" barrel under rib?

[ronaldrothb49]

as Sdilts said a little bow is an advantage. one clamp in the middle and the pressure from the bow hold it in place on the ends.

Larry's got a good idea. Plenty of guys straighten their barrel by smacking them on a tree. Professional high quality builders. Don't be gentle!

Correct you are! A lateral bow. Done deal though. The trick (for me) was,,,,,

Ingenious! Well done Sir, Thank you for sharing the photo of the set-up and the results.
Well done indeed.
I would have worried about it twisting under the pressure applied. How'd you file for the wood for fit?
A tri-corner or just the kerf from a saw cut?

Made a vertical cut then held the hand saw at 90 deg to the cut and relieved the top of the cut horizontally. (widened cut at the top) The soft pine with the cuts allowed the V shape to imbed in the cut. It really worked better than I expected.
Thanks

How do you solder the rib on “neatly”?
I’ve tinned both surfaces, used sharpie and soapstone where I don’t want solder to stick… still a lot of cleanup.
If the barrel is thick enough (like Hawkens) I prefer rivets made out of 16d nails.

The barrel is a Colerain taper octagon to round for a Harpers Ferry flintlock rifle. In the past I have used lots of flux, with low temp sil-tin solder. I am generous with the solder, and don't worry too much about being extra neat. I want good adhesion, so I just plan on some clean up. I like solder way better than rivets, but that don't mean your preference is not just a good.

Couple years ago I built an 1803 Harpers Ferry from the Rifle Shoppe. It came out so nice I’m considering ordering another 1803 and an 1805 pistol
