FSE_ that's a weird couple of posts. Have you done either of those things with the drill or torch before :confused:
I think an ice pick shoved thru the copper would be best , then shove cap tube into it
On the condenser end , cut the suction pipe in half , drill a hole through a coupler , pull cap tube thru pipe , shove through hole in coupler , put coupler in place.
All theory and sounds easy of course on paper ....
