I am making some bronze spreader tangs from layers of 1/16" silicon bronze ala Hereshoff. It would seem, not that I am second guessing the master, that round head screws would provide a better attachment to my spruce mast than the counter sunk method he recommends in Sensible Cruising Designs. It may not be as attractive but I am a little nervous about trying to get a counter sink properly in 1/16" material. They will be similar to the tangs specified for several of the boats in the book ie: built up from 4 layers and it seems that squeezing the whole arrangement under some round head screws would be better. Waddaythink????
