Greetings , and thanks for directing me to that tube .as has been said ,a picture is worth a thousand words. I don't have a air hammer ,or Toby hick mans experience , but I do see the set up for the bolt tong profile he uses.I do have a mech. hammer which does draw the reins faster than by hand. I also have a pile of 4130 x7/8round . I have no excuses for not concentrating on bolt tongs for the next 2 or 3 days. Thanks again for the direction and happy forging!
