Title: Raw hide backing questions
Post by: Fox on October 17, 2020, 03:28:28 pm
I just made some deer rawhide strips for a bow backing on a elm bow... I nailed them to a board and now they are real dry and flat. Iím about to go sand them super dry... whatís the next step?

Wet them good and glue them on , I like to put flesh side down. I use TB 3 and put on just like I would a snake skin . Pappy

Like Pappy said. Rehydrate rawhide. Make sure strips are wide enough to cover back of bow. After hide is soft and pliable put epidermis side down on a towel. Put a ďsizing layer of glue on both back of bow and flesh side of rawhide. I like to put masking tape on bow where I donít want glue to stick. Lay rawhide on back of bow. Stroke rawhide from handle area towards tips to get any air or access glue bubbles out. You can then carefully wrap with a ace bandage to get good contact for your glue joint. Be careful wrapping though. Make sure your hide doesnít move or wrinkle. Let it dry . Remove bandage. Use file to trim rawhide to edge and remove extra glue.

Itís best not to bend your bow for awhile till it dries out good again. Some people wait a few days. Some a few weeks

If by chance you find an air or excess glue pocket under the rawhide after you remove the wrap you can make a short cut lengthwise in the pocket and squeeze out the air and/or excess glue. I leave a wrap on rawhide and snake skin backing only for about an hour or 2. In that time the glue hasn't set up completely so you can still do this. Once the glue dries out completely you'll never see these slits.
 Also, strips of old bed sheets, first aid gauze or ace bandages make good wrapping materials.

I have shot mine after a couple of days, and think the bow is still got too much moisture, if you can wait, I think a week is good,,

I agree, Brad. Even though the rawhide feels dry moisture has creeped into the wood so it needs time to dissipate completely.

Okidoki, thanks guys. How should I join the two pieces of rawhide at the handle?

 You can just butt them together or do a skived overlap to blend the edges.  I usually sand the tapers about an inch long.

I use a scarf joint at the handle for a smooth transition. That is enough although I usually make my handle wrap with hemp string wrapped tightly around the handle and set in Massey finish(2ton epoxy thinned with acetone). The rawhide isn't necessary at the tips either but I sometimes wrap that end, about 6" from the tip with decorative thread set in super glue or Massey finish.

Okay ... whats a skived overlap? or a scarf joint?  ;D

A scarf joint is the end of each piece is cut at a sharp angle so they fit together without a noticeable joint. The beveled areas add more surface area for the glue joint. Skiving is a method to achieve a scarf joint.
