The OD is smaller than the ID.
First, I am painfully aware that a vast number will express their concerns about the practicality of this project and even question my sanity for even attempting it. Please resist the temptation and keep your comment to solving the problem at hand. Your reward in heaven will be great.
I wish to mount a bayonet lug on the barrel of a rifle. The problem is the inside diameter of the ring of the lug that slides onto the barrel is larger (ID = .655) than the outside diameter of the barrel (OD = .618). That means, if I did the arithmetic right, an all around gap of .0185 between the lug mounting ring and the barrel.
My first thought was to plug the hole for the barrel in the lug with either a force fit or brazed/soldered in plug. Then drill/ream the proper size hole to fit on the barrel. I no so sure that is a good idea. As after putting in the hole, the walls of the plug will be really thin.
When looking into brazing/soldering an unmodified lug to the barrel it appears that a gap of .020 can be accommodated. Remember, the gap between the lug ID and the barrel od is .0185 all around. Spacer wires/shims would be used to properly position the lug and to create a consistent gap for optimum flow in the joint.
I am thinking brazing/soldering is the way to go but I am open to other ideas on how to attach the lug to the barrel and why they would be better.
There is one perfect solution to the problem. I came up with a design that is sized to correctly fit the barrel. Unfortunately, no one is willing and or capable of executing my design. If you think you have what it takes contact me and I will send you the drawing.
