Backing a pyramid bow
« on: September 05, 2011, 04:42:45 pm »
Ok so I'm making a red oak board bow and decided I wanna back it with fiberglas tape. My question is when do I back the bow or does it matter? Should I back it right before I start Tillering or should j back I back it after Tillering when it's done.

on a side note, if i was going to do tip overlays on the bow, do i put them on before i back it or after? i put them on after right?

Tyler, you will want to back your bow before you start tillering; and make sure the glue is 100% dry before starting to tiller. The tip over lays can wait until everything else is done.

If you are talking like "floor tillering" you can still back it and proceed.

i had done some tillering. i ended up backing the bow anyways tho. i still had to thin down the limbs some to hit my target weight so we'll see what happens i guess

Lotsa stuff you can back with.  Brown paper bag and wood glue is a fair backing.  Cotton sheeting works well, too.  Pick the stitching out of a couple of old silk ties (don't use the ones with the hand painted hula dancers - send those to me) and glue those down.  Rawhide works well, too if it is thin. 
Guns have triggers. Bicycles have wheels. Trees and bows have wooden limbs.

Brown paper bag? No kidding! I guess the wood glue saturates the bag yea? And dries that way. Nice. Thanks. Hula dancers? ;)

Brown paper bags(almost any paper) is made from wood fibers and can be quite strong when saturated with glue.  Do a little test. Take a piece of brown paper bag and glue both sides to saturate the paper. Give it 24 hours to cure and try to pull it apart, not rip it mind you but pull it like it would be pulled when a bow is drawn.

You're right. I forgot what paper was actually made from.
