Damascus chambers and steel tubes

[Bindlestiff]

I had Bred sleeve a 16ga for me. According to Brad, what he did was remove the ribs and saw off the original barrels in front of the breach chambers. He then bored out the remaining breach material to accept the tubes and turned 16ga barrel tubes to zero tolerance of the size bored "through" what was the original chambers. He put the tubes into liquid nitrogen and slipped the tubes into the breach and when the tubes warmed up they were there to stay. Then laser welded the joint to make it about invisible when blued. He re-chambered the barrels and did whatever magic it took to prove point of aim, obtain proper balance, relay the ribs and fit forend & action back to proper working order.

The only thing he didn't do that I expected was to laser weld the joint in the breach end, I could see the hair thin line under the ejectors on the barrels breach ends. But, needless to say, I was happy with the results. The gun went from a non-shooter to a very nice, serviceable gun.

Robin, the method Brad used is the same as what is done in England. The bored out chamber is usually to the cartridge rim diameter. Rather than a square shoulder, the barrel tube has a very slight champher from the smaller diameter to the large diameter. This then gives a V groove weld prep.
