[QUOTE="Dart70ca, post: 101240, member: 3676"] I guess I'll find out, but we hardness tested it in the shop and, while the core was certainly pretty hard, the consensus was that this cheapo was case-hard. TIG puts WAY less heat into the piece than MIG or stick, plus we slow-cooled it in an insulating blanket after. Doing it at home, I would definitely pre-heat and slow cool in a bucket of garden lime. If this one snaps off, it'll be down inside the dolly pot so not dangerous, and we'll just weld the damned thing back on :) Good point, though, should have mentioned it myself I guess. [/QUOTE]
