Step 1: Marking the Pipe
The first thing was to mark out the pipe.
I first used a length of angle iron to mark a line along the pipe, by using angle iron you get a perfect line and all your lines will be parallel.
Once the first line was marked i measured the circumference of the pipe and devide it by 3 to give the spacing for the other lines. I marked the distance on the back of the tape measure so i could wrap the tape around the pipe for a more accurate mark.
Once you have the equal distances marked use the angle to mark a lines.
