Whole trees or branches in a frame

I've seen some whole trunks or branches used in a frame. How do they remove the bark without leaving tool marks on the tree or branch?

Hey, brad_bb -
We often incorporate logs or trees into our frames.
First we choose some unlucky person to remove the bark with a pressure washer; Then we lay it out for the joinery and cut it (no, not on the Hundegger wink )
The finish is first tackled with a grinder with 50 grit, or wire brush attachment, depending on the density of the leftover bark, and then with an 80 grit on the orbital, which will remove the scratches left from the orbital.
Nice, smooth, touchable wood with all the knots and branches, if wanted...Throw a nice Landark stain on it and - voila - you have a great tree in your house.

The bark "slips" in spring/early summer on most trees. The cambium is dividing to make wood and bark and is easily removed. You can often roll a log right out of its skin. To tie back into the time of harvest thread, this period is when the earlywood portion of a years growth ring happens, in about a month's time the lighter, less dense ring and the years' growth spurt happens. Hard to keep a tight jacket with all that going on.
