Multi-functional Adjustable Jig in Columbus (MAJiC) :jester:

I have built 4 bikes so far and I seem to spend alot of time clamping and un-clamping everything together in alignment for welding, then finding out that something slipped and threw everything out of alignment :rolleyes4: which would make me start over:(. Or I am setting up or taking down my work space and equipment so it is out of the way. So since the weather has been good for the last couple of weekends I decided to build a jig with built in clamps that will hold a frame for welding and can be left up and does not take up much space. this is what I have so far. The backbone is two 1"x3" 14ga rectangular tubing spaced 1.5" apart. I am using 5/16th in bolts spaced 4" apart to squeeze the backbone together as a clamp. I made the leveling bolts out of 3/8th in carriage bolts and nuts, one nut is welded to the bottom and the nut on top is for locking the leg in place

That looks great and should end any alignment problems for good. Be sure to post photos for the jig in action on your next build.

What a great idea! Hope you don't mind if I borrow some of your ideas. I've been thinking about a welding jig setup, but this makes much more sense than what I had in mind. Thanks for sharing this idea :-) !

Love the jig imamedik. I am struggling with a small alignment problem on my Tomahawk build as we speak. Funny how these things grow as the frame gets longer.
