I sure don't know that one. You might try typing in "log furniture forums" in google. You know there has to be some. If there is a forum of log furniture buildres somewhere, they are eagerly awaiting your question!

you probably won't even have to ask and wait for an answer. Search their archives.

This is the same problem that bowl turners face.   Suggest looking up "Natural Edge Bowls" and you should find some info.  I started turning bowls last year and I have noticed several issues with attempting to save the bark:

1)  Bugs.   With oak you will have large borers within  a month or two if you do not take the bark off.  Powder post beetles are worse with the bark on also.

2)  The bark seems to adhere better if you cut the tree in the winter.  Spring cut wood seems to shrink worse and loose the bark worse.

3)  It helps to slow the drying also.  I would guess that a kiln may solve these problems.

4)  Wood that shrinks alot is hard to retain the bark.  The fruit woods are the worst.  Oak and Walnut is a little better.

Thats all I have learned so far.  Suggest experimenting with the exact wood you are trying to use.

Hope that helps.

This is definately true out west, with soft woods. All of the rustic furniture that I leave the bark on was either cut , wind fall, or died standing in the winter. I usually try not to leave all of the bark on, but sometimes a customer asks me to do so. :-\  If it is an outside piece it is probably fine to leave all the bark attached.  To achieve a nice skip peeled look, these same trees work nice.  :)

I have been told that Sassafras will keep it's bark on real well. I have no experience with this, someone told me this once. :)

Saturating the bark with Tung oil every 3 days or so seems to work
fir me. If I let it get dry too soon, it peels off. If it starts to let go
I can't stop it. So start Tung oiling it as soon as you cut it. Seems to
work better with hardwood.

Fstedy,

Cut fresh, keep dry, dry quickly, move product. Avoid cutting in late spring. Reid

I have done this twice,

Douglas Fir bark on siding
It is some crazy cali thing and I cut some samples and sent them directly to the kiln.  The bark was firmly attached at the end of the kiln cycle.

Rustic furniture, bigleaf maple
Some work for myself and my method was to soak the bark in large amounts of penetrating oil with varnish.

Both of the projects held their bark well, sadly the crazy bark on siding was not a hit at the show.
