I use a variety of different sized mallets and center punches. I would say that the mallet I used on this video had a head that weighs approximately 6-8 oz. (120 - 225 gm) with a length of 9-10 inches (23-25 cm). For the center punch, I'm not sure on that particular instrument....I made these videos in 1987 or 88 and just don't remember. In the US, center punches can be bought in different sizes as most any hardware or home improvement store. Since different horns use different sized screws, the size of the punch should be selected so that it goes into any threaded whole without being so tight as to damage the threads. Most of my punches that I use I made from steel screw stock of various sizes.
