Title: Birch bark back?
Post by: SMeeres3030 on February 20, 2017, 08:20:37 pm
Hi guys I have an Osage I am just finishing up 66" non and 54#@28". I want to put birch Barack on back for some nice camadlouge. I have never used birch Barclay so any advise would be much appriciated! Glues? Where on back to splice? Where not to? Method of clamping for glue up? Thanks guys

Do it just like a snake skin or rawhide with TB glue. Birch bark is pretty bright for a camo isn't it? It will make for a nice looking bow, though.

Like Pat said, TB works fine. For a seamless look I cut the ends of each strip in a spot where there is only white. In other words I avoid cutting through one of the dark striped pores on the bark. I also do one section at a time.

Ok thanks guys so don't do all the strips at ounce? Should I let them dry one at a time as well? And where in the back should I be splicing them? Because I'll problem have 3 trips.

it'd be great to have a bunch of links with info on birch bark for bow backing, I'd love to use it one day

Yes you can do it all at once. I prefer hide glue. You can then apply them like veneers. Loon - it is pretty easy, a computer isn't going to help you much! Just try.

Been quite a few years since I have done one but I usually use bark from a tree large enough that it will do one limb from handle to tip, the bark can be peeled down to a very thin strip.  As to glue, practically anything will work but TB3 works well.

Yes a few of us have tried epoxy with mixed results.The epoxy needs to be reduced very thin to avoid any cracks appearing later on the back later from flexing.Tite Bond 3 worked the best for me in the end.I can see how hide glue would work good though too.Doing one limb then the other all within an hour I'd say.

Ok thanks guys I'll keep u posted. I had some bark drying for awhile and it has curled on me a bit? Any tricks to get that out? Heat? Steam?

Just a soaking in some warm water is all I do.

As already said, soak in water, glue with titebond and I wrap with an ace bandage just long enough for the glue to start setting (maybe 1 hour).
Also you can dye or stain the back after it all drys for a darker look and better camo if desired. Heres a pic of one I recently finished with dye, birch bark on osage.
