8 3/4 gear setup

Man I like that jig you made........but I have a suggestion......and no offense meant, I think it's great. But as you assemble that case, it's going to get really heavy. Those vise jaws may let you down holding that piece of round pipe stock. Why not take it out and weld a piece if say 6" x 2" 1/4" flat plate on the end? That would give the vise a better bite.

Just a suggestion. Your feet may thank you.
