Curt,
No it's good to keep this kind of stuff coming. I have never used a table before my first bike was built using fixture-less techniques. Just trying to add tooling to speed up the next (current) build. So would you recoommend the inserts end where the chain stay's enter? It seems that would be your concern? That if any overhang is left when those are brazed they would need to be chased out in order to slide over the post.
