Well I'm finishing up my personal project for my fabrication course in my Production welding program. I was debating on doing a frame jig of some sorts but in the time frame we had left I dumbed down my project. So instead I just made a alignment block. It's two 3/4" pieces of 6061 aluminum that will get bolted together. The slot down the middle is to allow the dropout spacer or a surface gauge to slide back and forth and firmly bolted in place if needed. I still have to drill and tap some piece and counter sink the holes in the lower half of the block to allow the button head hex bolts to sit recessed. The BB post just slides right out so top block and be ground flat if needed. I made a simple block that I'll drill and tap to allow a bolt to be threaded in act as a surface gauge. It's the "P" shaped block that's quasi attached to the vertical slotted post. Overall I'm pretty happy with how it came out and should work fine as I designed everything myself up Autocad and cut out on the Water Jet.
