Those aren't hard or easy ways; they are wrong ways, especially if the
splice is outside where you will eventually have problems due to
condensation and possible water penetration. The dielectric is
intended to be inside a waterproof seal because this feedline is not
pressurized. I'd terminate each end with an andrew male (probably a
N) and join the two ends with a good quality silver plated N bullet
(a N female on each end).

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.
