Laurie:
I have been having some work done by firm in northern Ilinois that has a laser welder. This machine is just amazing and just may well be perfectly suited to barrel repair. There is so little heat actually put into the work that it could weld right next to the solder joints. Welds are made with filler rod as small as .005" diameter.
I spoke to the owner yesterday and asked him if he was interested in doing this kind of work and he was all for it. I have no interest in this company except for the fact that they have done some truly impressive work for me in a timely fasion.
If you are interested you can contact John at
