Couldn't find a good palce to post this, but I was really excited to find it. Very useful for those with more ambition than money or a small job.
Angle finder can be had for a few bucks. Input tubing sizes, angle of joint, etc. and it prints out a template to wrap around the tube and mark your cut. Took me a minute or two with the angle grinder once marked. Also allows for offsets. Tried it out this morning and although my welding needs some work, the template was dead on. Make sure you print without resizing.
