The shape of the cast iron drill press part looks like it could be fabricated out of some pipe and other metal pretty easy or have a local machine shop make one. Or like some of the others have said, Hi nickle rod or wire and pre-heat and post heat , cool very slowly. Good luck

You must pre heat the casting 350 to 500 deg F
with out delay the welding must take place very quickly after pre heat
You must also Lightly peen the weld after each bead and alternate the welding on both sides. you must grind out both sides making a 60 to 90 deg bevel
you can use 7018 because your break is not moer than 60% of the casting
Now here is the fun part what cast rod are you going to use?????
there is Aws category RCI , ECI , EST AND ENI cast rods
good luck

There is a lot of good quality cast rods on the market I would vee out one side and bolt it back up .Then i would postion tack on the press remove it to the bench weld it up ,all this time the peice is pre-heated to about 100 degees ,or as hot as comfortable to handle >check it a couple of times for fit up,Vee the other side and weld up The whole time gently peening let it cool slowly and youll be good to go till your new peice comes in!

it can be done & i do it all the time when i need to with good results...i take nickle base stainless steel stick rods,beat the flux off,sand it down good & clean...clean the cast iron up & V it out real good with a bevel...preheat with the oxy/ace torch & tig it back just like you would Stainless steel...it can be done

It may be cast steel. Not a whole lot of stuff is made out of cast iron anymore. Cast steel will weld much bettter. If it's Chinese... who knows?

I take it you are from Montana or in Montana. I was born in Sidney, Mt.

Good luck. Sounds like you've got some guys to help out.
