Maybe you guys can help me out here. . .I am trying to carve a top for the first time. Problem is I don't know how the final thickness is supposed to be for a 336 or how much arch to have. I have some 335 plans that say .225" thick with a 1/2" arch for a starting plate thickness of .7225". I am thinking that i'll go with about .4" carved out and another .2" thick for the 336. Any input?
