my experience with cast iron is that if you are super careful about cleanliness, have impeccable technique and maintain perfect distance from the puddle through the entire weld, with slow cooling and careful setup, that when it breaks into even more pieces than you started with you can tell yourself you did it all correctly, cut your losses and braise the part like you should have in the first place. The best welders I know will not weld cast iron at all. The best one I know won't even braise it, at least not for customers, as in her experiences more than half the time the customer is faced with another broken part fairly soon. Now, this dos not apply to all kinds of jobs. Plenty of engine block cracks are very repairable, but something like that drill press part? It will never have strength. it's probably just a cabinet piece anyway, probably broke because it was dropped, and maybe it will survive.... Don't try this shit with a connecting rod though.
Grinder and paint make me the welder I ain't.
I hope this is going to be a new series.
HAAAAAAA!
Very good video, keep it up.
Yall need to take the "budget builds" and compile them all into one big "how to" section. Especially nowadays
