The hard way: A friend used "big enough" brass rod, 1 1/2" long, milled 
or drilled a hole, in the ends, to fit the center conductor. Tin and 
solder to splice the center conductors. Copper pipe, big enough, 3 to 4 
inches long to slip over outer copper, tin and solder. (slide the outer 
pipe on first). Used some 1/8"x 6" al strips, with hose clamps, as a splint.

Easy way: Tape the two pieces side by side, wrap copper flashing on 
outer and inner, solder. Sandwich bag, tape.
