Title: Question about tapering
Post by: BSV on December 30, 2016, 07:15:37 pm
Hey everyone,I know in laminated bows the lams are tapered, but in self-bows is the thickness  tapered the length of the limb or the width taper the length of the limb or a comb of both? thanks in advance.......Burt..... Instead of starting over again I meant for tillering and weight reduction through-out tillering :) :)

I usually taper the thickness but often taper the width when I feel the limb is getting too thin. Jawge

The design that is known as a pyramid bow is tapered in width only.  As Jawge sometimes tapers the width of other designs if they are  getting too thin, sometimes pyramid bows are tapered in thickness--usually when the outer limbs are too stiff.

thanks guys,I know every piece is different but is there a thickness starting point you like,or is that determined by floor tillering?   Burt

I do like George does.
 I generally start at about 3/4" to 5/8" at the fades and reduce the thickness until the limbs bend evenly and together.

I make nothing but pyramid  bows, which do not taper in thickness. I always plan to end up at about 9/16" thick for Osage, wider and a little thinner for ash, hickory, locust, and generally all the white woods. I have never had yew to work with. Would have to study that before making shavings.

I have made a ton of pyramid bows and they do start out with no thickness taper, but as they get tillered they always end up with a slight taper to get the bend right. I leave the last 6" inches a tad stiff, i fill it makes a better shooting and better performing bow. Jmho
