Great looking jig! I like to use a reciprocating saw for most cuts, but the idea is the same. I haven't seen it mentioned yet, but it seems like a really good idea to use a sleeve inside the tubes on these things. much easier to do the welds, and not have the cracking issues on the ground smooth (thin) welds once completed. you can buy the sleeves, but I just use a size smaller ex tubing and cut my own.
sometimes you can't just go buy off the shelf headers (or intake tubes ) for your particular car/engine setup

Can't agree with the sleeves.

Spend any time you would fooling around with making or cutting up sleeves, practicing your welding instead, and you'll be further ahead.

Practice on scraps and watch that you're getting penetration gribnets on the inside of your tubes and when you grind off the proud, there will always be full weld left behind right through the material.

[shrug] agree or disagree. doesn't matter to me. I prefer using the inserts, even though my welding skills are second to none. just like yours.

BTW. I can still piss further than you can.

another nice fixture pugsy, i'm ripping that one off too
sometimes a straight line and a chop saw is all you need for a good cut.
i do enough of this stuff to use a similar angle finder as the pivot.
dang, i do like this site. 2 good fixtures in this thread.

I'll have to try something like that next time.
I cut all my bends with a zip cut disc.

I did make up a jig however to draw accurate lines.
Nice marking Jig Pugsy! I love making things that make my work go smoother!
