    No need to yell...

    5/8" is the correct size. What sort of trouble are you having?

    They sometimes will not bury the head below the surface of plank the smaller heads of tacks that i ran out of were nice but i don't know where they came from. But the tack that was easy to clench has a head 5/32 dia is this enough? Sorry for yelling

    You shouldn't have trouble setting the larger heads in cedar. The heads will usually stay proud if you are planking with spanish cedar, mahogany or cherry (as in a sheer strake). A couple things to try is to make sure you are setting the tacks in the right orientation (so the bend goes across the flat), make sure you are getting a proper clench, and make sure you are backing fully.

    If you are not sure you are getting a proper clench, practice on scrap, bust it apart and look at the nails. They should form a nice curl.
