I use 3/4" pine for the whole jig. Works fine. I need to make more pucks. I love the original and it makes my necks very consistance. But now guys are asking for a more V or U shape. So I need to rethink a bit of this. Those asking about the U necks want them a bit thicker. So I assume I need to make the small puck a bit taller. (yes?)
Thanks again for a great jig.
BTW: The bowl or plate bit works excellent for this jig. It has rounded corners so you don't get the grooved lines like in the pics above.
