I'm notching the additional 4130 bars for my cage using a Harbor Freight tubing notcher, it works great, perfect notches. I don't have a problem figuring the angles, measuring, etc., I build stuff.
But....On the Halo, the bending process distorted the tube a little bit and cutting the notch in the tube that will butt into the halo is a total bitch, I roughed it in and finished with a file but it's not perfect.
My question is...For Tig Welding, how much of a gap between parts is acceptable?
FYI: I'm not welding it, I have a guy lined up for that.
