so I drilled 1/8" holes at each end of the crack, heated the area around the crack with my oxy torch, tig welded the cracked area with 309L filler a little at a time (peening with an air chisel with blunt pointed bit after each weld section) then dropped in a bucket full of vermiculite I had laying around to slowly cool....we'll see LOL

Check next to the weld to see if it's hard(brittle)...there is a chance.
I use "NI-99" too TIG cast iron...works good !
