Emmert Pattern Maker's Vice Repair Question

Hey there colleagues - Divine Providence sent a genuine Emmert's patternmaker's vice to me, and I cannot wait to start a restoration thread on this ingenious piece of early 20c engineering. Sadly, the vice arrived with a critical lever broken off. I'm wondering if anyone out there has some ideas on how I might go about repairing this cast iron? Something deep in my core says JB Weld won't cut it.

    JB Weld wouldn't work. Needs to be brazed

    ditto on the brazing - you'll exert way too much force on the lever for JB Weld

    Go to an automotive machine shop, or speed shop (where repair/mods to cast iron heads and engine blocks are done) they could direct to a qualified welder. it does need to be brazed, preferably arc welded with a high nickel content rod to give strength...but "tourched" brass could also work...it would be best to disassemble it because in a perfect environment the base metal or part needs to be heated to a high temperature so the action of brazing or "welding" does not effect the surrounding area with cracks from expansion/contraction.

      Agree with Joe M ...as you don't want too hear the deadly "TINK" ( cast iron cracking due to improper heating)

    after looking at the above parts list...the "cam ring" looks to be the part and at 125.00....probably cheaper than a shop would weld it for you...unless they take it on as a "challenge" for cheap. Was the package insured?

    must be a common problem

    Thank you fellas! - Yep, welding it is the way to go. I'd rather not buy replacement parts...i luckily have a friend who is an experienced welder and he can help me. I'll post more when I get this thing fixed up.
