quick question
how long to wait to let the sinew cure on the bow before adding a rawhide back?
I haven't done this before so its something new for me.
appreciate any help

I have put rawhide on a bow but not over sinew. In fact, I thought I read not to put rawhide over sinew. Hopefully, someone in the know will chime in. I'm curious as well because I will someday sinew a bow, I just need more practice in bow making.
-
Is there a reason you're adding rawhide over sinew? I did it on one bow but I was copying a bow that Jay Massey had made. It will probably detract from the performance by adding physical weight.
You can add rawhide any time after you add the sinew but I think I'd wait a couple of weeks. When you add rawhide over sinew you are adding more moisture to the mix so give it enough time to dry out again after applying the rawhide. What glue are you using?
-
I'd wait at least 2 weeks, the last thing you want is mildew/rot under the rawhide. Then wait 2 more after the rawhide is added.

thanks for the responses
from a naturally reflexed hackberry stave...short flat bow 57" ntn...dry after sinewing total weight 512 grams
tillered out at 35# at 28" , about 2" at the fades...I thought, why not play with it a little see if i can get a little more # out of it...
Pat B,
used knoxs to attach buffalo sinew-from at most, foot long pieces, of leg tendon
I wanted to try the rawhide backing to get a flat even surface for a woodburned design
appreciate your experise
-
Wood burned design? How so?
-
oh and i had put two layers of sinew on, let it gel and partially dry, and wrapped it with damp cotton cloth strips
left it over night...peeled the cloth off carefully in the morning using a little warm water
-
planning to try wood burning fine lines into the rawhide...not a good idea?
-
Not a good idea in my opinion. Maybe try drawing the design on the rawhide with art pens?
-
Thanks Pearl...you're probably right
I guess there is that danger of scoring and actually creating a place for a hinge...ok...I'll have to think this through
-
Not a hinge, but a tear. Rawhide can tear when one of the surfaces is compromised. If not? You can stretch it the moon and back.
-
I agree with Pearlie. I've done a few using India ink that turned out well.
Here is one I did for a TradGang Bow Trade a few years ago...

Are you planning on using the Knox for the rawhide too? I've started using hide glue(same as Knox) and like the way it "sucks" the rawhide down to the surface.
-
thanks Pearl
ok, that makes sense... have a nice clean deer skin I was gonna brain tan rolled up, and will likely use
Pat B,
Thanks for sharing the rawhide back pics
yeah, planning to use the knox for the rawhide and wrap it up with cloth strips as I did the sinew.
have used my own hide glue before, but thought i oughta try out this knox people have been talkin about. the way it sticks sinew to my fingernail
and the table is proving its good reliable stuff.
I did cut a long strip from an old rubber boot for a band if that might work better than the cloth pulled tight? or maybe both? what are your thoughts?
-
You can just put it on without wrapping and use a hair dryer to keep the glue live. Keep painting water onto the rawhide surface and use the hair dryer as you press the rawhide down and work out any bubbles.
-
I usually wrap rawhide with strips of old bed sheets but remove it after an hour or so. I can then check for air bubbles or glue pockets then trim the excess rawhide with a sharp razor and set it aside to dry.
-
I do it just like Pat B does. If the rawhide feels hard and less flexible I will wrap it with an Ace bandage to be sure it forms around. Then when Im done I will either leave that Ace pattern on for effect, or use a damp towel to level off the rawhide smooth.
