I used this technique on my first hardline run at the "new" QTH 17 years
ago.  It has outlasted almost all of my homebrew hardline connectors.
That told me something!  I now use that technique for all my hardline to
RG-213 or RG-59 cables (with ground lugs soldered to the braid).  I use
small plastic bottles wrapped with Scotch 33 to prevent uV deterioration
and to hold the bottle in place.  This  works on all HF bands.

I have made home brew hardline splices using a small copper tube 
soldered over the center conductors for approximately 1/2 inch, then
wrapped with scotch 33, and an 8 inch sleeve of the next size aluminum
tubing slotted at both ends, wrapped with Scotch 33, and hose clamped.
I have two such splices which continue to function several years after
repairing lawnmower induced damage.
