I am not going to completely let the cat outa the bag, but I just sold a Rockwell Hardness Tester to another Gunco member who is attempting to start up a side business heat treating these blanks for people. I think it's a fantastic idea, since they are not an FFL item. Gives all us homebuilders access to a higher quality standard, that only a handful of guys have had access to in the past. I know that some folks have the equipment/procedures for a full heat treat, but I bet 98% of the homebuilders that bend their own flats don't. This will be a good thing for the entire community. I wish him well, and hope that he gets his process dialed in soon, and starts an "open for business" thread.
