this is kinda headed towards alex,, i have a possible large walnut crotch coming my way, i mean large!!! its 38" at the small end and the crotch spans at least 60" the two limbs were 20" limbs. so my question is. do i trim the limbs off to a manageable size or do i leave it full width.. it would be much easier to cut if i trimmed back the limbs and keep the crotch area in the center of the slab. which means the limbs would probally be trimmed back to around 45".. so you sawyers out there what say yee?
