A drill press and the jig in that link would have been nice!Beautiful job! After you cut the tubes how did you drill the holes for the LoPro attachment bolts? Thanks.
The process I used was pretty simple. I left one LoPro still installed on the newly cut length of pipe and laid it on the flat garage floor upside down (upside down so the LoPro will prevent the pipe from rolling). Then line up the second LoPro (also upside down) on the outside of the pipe. Stick a pencil through the LoPro fitting to make a mark on the pipe. The I used a hammer and punch on the marked pipe so the drill bit would wander. I drilled out one hole, put the LoPro fitting inside the pipe, then drilled through the pipe again, this time using the LoPro to guide the bit through the other end of the pipe. It was a pretty easy process and I am pleased with the results.
