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.
Copy that rusty we did think about That but opted to machine 2 flats on the end of the round bar that is clamped in the vice I think what I will do is make those 2 flats the whole length of the vice and give me a lot more strength. we were able to put a lot of weight on it and it didn't budge so I think will be all right but thanks for the suggestion
