I live in the Tulsa Oklahoma area and I'm finding myself in need of some Cast iron I can break and practice repairing. Unfortunately I have a taper attachment that had the mounting points broken when a cable snapped while moving a lathe. I have a tig welder and I've read up on the technique to do tig brazing on cast iron but I'd like some old junk cast iron to actually practice repairing. I imagine whatever I try the first few times will come out crap so I'm not offering to repair something for anyone just looking for some material that is unwanted or fairly cheap I can drive a few hours in any direction. Southern Missouri, western arkansas and potentially down to dallas are in range.
