Is there any consensus on the length of shank that would need to be
inserted/glued into the hammer butt for adequate strength/stability? Seems
to me one shank diameter would be too little, maybe two shank diameters at
a minimum - that would be 3/8"? Of course, more would be merrier, but if I
am to use these shortie shanks, I may not have that luxury. Any thoughts?
