Cast iron dilema
I’m restoring an old gas stove. I broke a screw off in a cast iron burner top while trying to dismantle everything. I tried everything to remove the screw but I ended up drilling it out. I know it was cast iron, but I didn’t stop and think before I welded the hole in with 6011. My plan was to weld it full, drill it out, and tap it with a 10-32 tap. One of the three spokes holding the center part cracked after welding. I tried drilling it out, but it was too hard. I tried tempering the weld to soften it a little but then developed another crack. Now I can’t drill the weld and I can’t anneal it because it will crack again.
I know there is someone smarter than me on here that can give me some advice. I would really appreciate it as these parts are very difficult to find online.
