Birch bark backing
« on: October 22, 2016, 05:08:14 pm »
So i got some bark and it is pretty thick. Does it need to be thinned down? How thick is it when applied typically?

Paper thin, at least it is on my Horn Bow.

You should be able to peel thin layers off of what you have. Is it paper(canoe) birch?

I got plenty of river Burch in the yard and they r peeling like crazy since hurricane Mathew!  Can you piece it or does it have to be one continous sheet? I have decided to make a red oak board bow and this would look better than fiberglass drywall tape me thinks!!!

My bow has thin 1/2" strips layered continously down the limb.

Paper birch is the only birch bark I've heard of using as backing and it can be use decoratively or as a moisture barrier. I don't thing river birch bark would be more than decorative.

Tight bond III should make it a moisture barrier, right?

I can work with this!  So let's say I back my red oak board bow with the fiberglass tape. After its cleaned up can I put birch bark on top for looks. This is sounding better looking.

Why  are you using FG tape  as a backing? There are lots of backing materials better than FG tape. IMO.

Wow that's great Patm!!!    Do you glue the paper thin bark and coat it with Tightbond II and sand it again?  It's a beautiful bow for sure!!!

sleek...It comes off in layers like Pat said.I had to get mine from a canoe maker in Oregon since there's not much birch growing here.Thickness wise I get it around typing paper thin ten/one thousands thick and 1.5" wide or as wide as the bow.A little thicker does'n hurt I guess but below 1/32" thick anyway.I'd soak it in water then to make it a little more pliable for the characterish places on a bow.Usually around 2' long for my use.You can get it longer if you want.TB 3 works good for applying it on.Sizng both surfaces.Put it on just like a snake skin.I've seen people wrap it on too in thinner strips, but I don't prefer to do it that way.Each to his own.It does seem to be a very good vapor barrier.I use it on sinew backed bows.Just as good as snake skin.

Patb that's what is on a how to site I found. What else can be used. I don't like the idea of silk or linen or paper and have no sinew. I am toying with maybe a one eight strip of wood but that sounds hard for a newbie. I figured fiberglass would help me with strength the easiest. I am going to put a cedar handle on it.

   It's just glued on over the sinew and coated with tru-oil and wax. No point in sanding it.

  BTW why are you against silk/linen and OK with glass tape, especially on a primitive site? Won't get any support for that.
