Many years ago I made up some custom blocking hammers. Since then many companies domestic and foreign have come out with similar tools. When I made mine I also made one out of aluminum. It was a total waste because it was too light weight for blocking. I have been investigating the different properties of magnesium lately and have found that some tool builders are using it for some of their shrinking dies. It has a different affect on aluminum and brass than some of the plastics and other composite type materials. I recently aquired some big pieces of magnesium (this stuff is federally regulated, must be used in bomb const? and hard to get in large pieces) I am going to try it in some of my current tool aplications and if I see something good I will pass It on.
