OHHH that is a tought ? I am calling me LFS now I woill ask I think they are tempered?
OK here is the deal HE said he know people who have but doing it is hard cause of the bow front if you try and do it with a press it will wobbles and doing sideway free handel the drill doesn't stay very stedy?
SO I guess obviously plese don't hold me actountable LOL but it is not temper but I would check wit hthe MANUFACTURE IMO?
