Title: Parchment as Backing???
Post by: arachnid on November 25, 2014, 02:20:51 am
Hi guys.

I don`t have easy access to rawhide BUT I do have quite easy access to parchment.
I understand it`s quite similar to rawhide- will it work as a bow backing?

Yes but get the thickest stuff you can find or glue on a couple of thinner layers.

Thanks....
Will Elmer`s wood glue hold up? That`s what I have... (I  might be able to get Titebond I...)

Is it really that different? Tightbond is kind of expensive....

Parchment is a pretty broad term. What can you get exactly? Real parchment IS rawhide.

I`m jewish and I have access to the parchment on which Sefer Torah is writen.
It`s cow skin proceced to remove the hair and the it`s thinned down. thats it basiclly.

Is it any good for backing?

 That's no different from regular rawhide apart from the thinning process. People tend to thin rawhide for bow backing as well.

Great!  :D
Thanks Pat.

What about the glue? Is Elmer's that bad for rawhide?

Many people successfully use Elmer's or they used to before titebond came along.

Ya don't want to use the cheap Elmer's glue that's typically used in elementary school for paper craft projects.
I used Elmer's wood glue for years 'n' years in my woodworking adventures.
Elmer's & Titebond are PVA adhesives with differing "additives" whose purpose is to distinguish themselves from a marketing standpoint. 
Strickly from strength standpoint, and imho, there's little/no difference.  Elmer's produces a clear-colored joint, which is good in lotsa woodworking projects ... not so important in bow-building.  Additives in Titebond do produce a more water-resistant joint, which is why I use for bow-building.  It is claimed that Titebond cures to near full strength more quickly than Elmer's.
For bow-building, I've always used Titebond.

Any of the water based carpenters glues will work; Elmers or TB.

Well I use only Elmer's wood glue (the yellow stuff... not so cheap ;D) for my bow building and I never had problems with it.Titbond came to stores around here only reacenly and it's expensive for a small amount of glue.If it's only better becaus it's water-proof - I'll go with Elmer's. :)

When adding backings water proof isn't necessary. After you seal the bow, moisture shouldn't be an issue.

The Elmer's yellow glue works just fine. I had a bow with a rawhide backing glued down with it and it held up to years of use in all weather.

You can always get some unflavoured gelatin, make up some hide glue with it and your golden

Have used goat parchment I got from Ebay and got some real nice results. I always use waterproof woodglue for glue-on. I mean why bothering using something else!?

Hide glue does give a better bond... The glue can penetrate deeper into the rawhide and holds everything together as a more homogenous unit.

How do yall water seal rawhide?

Tru-oil and wax works very well.

I have no idea why I didnt guess that. I use it over snake skins. But heres a question, what if you dont want a gloss finish, just a flat mat?
Title: Re: Parchment as Backing???

Steel wool and just slap a coat of wax on without polishing it before you head out.

I use regular wood varnish to finish my bow. I like the glossy  look.... :laugh:
I also have teak-oil but I`ve never used it on bows. Will it give the same glossy effect?
