Some of you may remember the big milling machine vice I asked about welding up ages back but the job seemed to fall into a black hole and never got spoke of again, well finally got around to it, mostly because I needed to hold a workpiece bigger than my little milacron vice could handle that couldnt be bolted to the milling machine table. Necessity is the mother of invention and all that.
Sadly the pictures have turned out completely crap, but I vee'd the edges up really aggressively with a grinder, then decided it wasnt enough, so milled them into a bigger vee, then root welded with the tig and some cast iron rods, then infilled with progressive passes using the tig but 304L stainless rods (ok I confess, I ran out of the cast rods) and the meter said 260amps, which I can believe as it kept throwing the main breaker on the 3 phase panel when I was doing infil runs and the torch got mighty warm, really must fix that leak on the watercooler.
I used it in (lots of) anger after, it worked perfectly, so I painted it green and regreased it and now and the job is done.
Thanks to the original commenters, especially the person who suggested stainless filler rod would be acceptable on cast iron.
