Hardtail jig

I've been looking at the hardtail builds on here and everyone seems to have a jig for the frame. Are you guys building a jig(if so what are you using) or buying one?? I'd like to mock up my 450 and tack it together myself. I'll pay someone to weld it together because I'm not a great welder and I'd like to stay alive.

If you're just looking for plans to build your own frame jig, this is one of the best i've found online.

Also be sure to check out the sticky at the top of this forum from Von called "So You Want to Build a Bobber/Chopper" there's lots of good frame info in there too.

I actually just made one today out of some angle Iron and a 2X12. Now I just need to borrow a welder
