Hello, I’m new to sketchup and am passionate about timberframing and general woodworking without screws or nails.
So I’m having fun making up plans for projects I plan to make this summer. But right now for one of my plans I’m just wondering if anybody has a rule of thumb on how a long log’s diameter reduces as you get higher.
So in my situation I need a 20’ long round log and am wondering what dimensions I should make it at the base and at the top (just to be safe). I’m aware that every tree grew differently and that the species is relevant to this outcome.
Just wondering if anybody can come up with a rule of thumb for this reduction in diameter. ’
