Knife blade outer limbs????
« on: December 17, 2020, 09:04:30 am »
If I where to make these knife blade outer limbs would they taper in width? Would they bend or not bend ? Would they have reflex in them? Would the fact that they less mass make up for the reflex? Does the working part of the limb need to be 8 times as wide as where the non bending limb start? That’s enough questions for now. Arvin

When you say 'knife blade' outer limbs are you talking about narrow levers like the ones on Badger's flight bows shown in TBBV4 in the Mass Principle chapter?

Don’t know I don’t have that volume. Maybe like the ones on Turkish bows. Skinny and light. I need some pics side and top profile.

Check out Dave Mead bows if you want to see knife blade siyahs Arvin. He has a web site on utube if that is what you are referring to. He seems to be able to line every thing up straight,and the siyahs are pretty long, and sharply angled. Akin to mongol bows.With 2 bamboo slats ,and a wood handle, and watching him shoot some through a chrony he seems to get good speeds. You may talking about a regular recurve though. Not sure.

The turkish type is just tapered.  They are static.  The limb doesn't need to be any wider than what you are using currently.

  You can google plenty of images of this type of siyah.   It's only going to change the weight of your tips, nothing more needs to be done.

  Years ago David Brunetta built a little bow with knife blade outer limbs, I think Allen case set a record with it. The outers were about 3/4" deep and had holes driller through it for about the last 6" or so. maybe Allen still has the bow.

David’s bows were something else. I still go back and look at his photo gallery from time to time.

Typical dimensions for a Turkish bows tips were around 75mm long from base of curve to nock. 12mm wide/17mm thick. Flat on the back and triangular in cross section. The sides are slightly convex and the base on the belly side around 2-3mm wide.
The nock slot is cut directly into the back. About 5mm deep.
Sorry for the metric dimensions :)
I could take some photos of mine if you want?

You would think a good friend would send me a autographed copy for Christmas. 😁

Ok I’ve been saving these belly drops . Looks like I will get some use from them as test limbs. Here we go with different knife blade bows.

Is a belly drop wood you split off the belly getting closer to thickness?
