An experimental warbow
Rich Saffold:
;D Well that is looking a bit more "normal". ;)

Richard,
Almost dissappointing isn't it! Sometimes quite a few inches of glued in reflex can dissappear, but you can tell it is there by the increased stiffness of the bow. Of course every now and then just to throw you off you'll glue in five inches of reflex and it will still all be there when it comes out the clamps! I think that very small differences in the thickness or strength of the backing makes a big difference.
Glued on some horn for nocks this morning so will be able to shape them later on.
Also did some basic shaping in tapers for a 150lb Ipe warbow. I'll wait to see how this experimental bow turns out to glue that one up though.
Now off out to cust some dogwood for arrows.

Mark, the bow is looking good, I am convinced that you don't need all that reflex for record breaking performance. My bows are getting straighter all the time and concentrating more on where to concentrate the bend and controlling the mass, Are you going to tiller this bow into the arc of a circle or with a stiff mid-section? How long is the bow?
Mark, what you said about shooting off a frame is a good question. Present flight rules are more about the flight shooter and not the bows are bowyers so mush be shot by hand. A lot of us are more into building bows and want to see their potential. A hand-shot bow, shot by an experienced distance shooter or speed shooter can outshoot the machine shot bow considerably as the bow hand will be in motion adding up to about 20 fps to a shot. The only way I know to duplicate this for a test would be to shoot the bow through the machine and set is so a 4" spring is compressed against the bow when it is at full draw, even 1/2 draw would likley work, this would act like an active bow hand. You would have to check the speed of the bow shot in a static mode and then shot with the spring loaded bow to verify the actual advantage, I would set the spring to add about 10 fps as this would be average for a good flight shooter. Be kind of cool to start a registry for tested bows on both sides of the pond.

Steve,
This bow will be a basic full arc bow, or as close as I can get it as this is what David wants. I will leave the centre slightly stiff.
I am slowly building up my knowledge for the "record breaker" or at least what I hope may be one.
I recently made a 60lb longbow with a 20 inch stiff handle and it worked well. Out of the sister stave for this one with a bamboo backing. Came out of the glue up flat though I put in a couple of inches of reflex. It was a swap for a knife from Danny, one of my brother-in-laws. The bow seemed to perform very well in terms of distance. Danny also did quite well with it first time out at our field club so the formula must be failry stable to shoot.
I guess we could agree a standard shooting machine. This would allow some comparative tests and results on both sides of the big pond. Could be fun. It would have to be failry portable so I could transport it to the filed I can shoot in.

Mark, I think it will end up faster,and I think the original reflex would be good on a fast 40# bow that long. My experiences are the same as Steve's, even though we can compare bows on occasion at the S. Cal. gatherings. I find my fastest bows are very close to straight as well.
My latest slender longbows have been r/d in fashion with the bend concentrated closer to the handle than usual with very straight outer limbs..
I can see this shooting machine looking like a big crossbow with interchangeable limbs ;)
