Boo Yew Primitive

I have 2 or  3 bows on my waiting list, but it's a matter of matching the timber to the requirement and also factoring the urgency/enthusiasm etc.
One bow was to be a boo/yew heavy weight roving warbow made from a pair of matched wonky billets for my mate Rob... unfortunately he had an accident fracturing his arm and damaging the nerve. That meant he wasn't going to be shooting heavy bows again, but he's working up to about 45#.
This sort of injury can knock you back a bit, so I've decide to jump to and use the wonky billets to try and make a nice fast boo backed Yew primitive of about 45# at 30" draw which will do nicely for field shooting and with suitable arrows should manage to rove as well.
The billets have some nice natural deflex/reflex which, having trimmed them to length (allowing a bit extra) look even better. Having sawn them to rough taper, cleaned them up with rasp and spokeshave and spliced them it's looking very promising.


The Z splice is short (less than 3"), but this is fine as the back of the bow will be a continuous length of bamboo.The yew belly being in compression doesn't need much of a splice, in fact the billets could probably be butted together and work fine in compression! Obviously one wouldn't risk doing that as a slight mishap whilst stringing the bow could easily flex it slightly the wrong way and break a simple butt joint.
There is over all an inch or so of deflex, but I'll jig it up for gluing on the boo back to pull the tips into maybe an inch of reflex. That's one reason for getting the billets to a reasonably even thickness taper. It means that it can be glued without using a former, I'll simply strap it down at the grip to a length of 2"x2", and


the tips can be blocked up into a bit of reflex relying on the thickness taper to give a smoothly blended curve. A dry run first will be needed, but it's not going to be a big bend, so it should be fine.

  1. what sort of marks do you write on a long bow except of the weight and th draw ( 60#@26 for exemple)
    thank for your answer ( jean.louis.ancion@skynet.be) thank you for all your interesting diary very useful for me

  2. I don't always mark them... but if I do it would jut be my initials the year (just the last 2 digits), the weight and drawlength.
    e.g
    DH '20

    45# @ 30"
