bow stretcher
« on: February 27, 2010, 02:22:58 pm »
how do you turn a 60" bow inot a 68" bow? either find a way to stretch the wood or expirement.

i didn't like how this was before the tips, so with the careful aid of a hack saw and sand paper i was able to slip these tips in. after i made the scrap bow i liked the tips so much, i tried them on some shorter bows, yeah the weight dropped on th first one, but i built up the rest i made to compensate.
 it's hickory back ipe with hickory tips. draws 30#@28" 1 1/2"@ the fades and 1/2" tips

the hardest part was setting it up on the tillering stick one handed for the picture

not much shock at all. the cross section is that of an elipse barely a half inch wide at the thickest, the little bit of shock far out weighs the lack of stack, so i was happy i think i could slim the tips even more if i wanted to, might try it... ;)

Bowskin...are these just glued on ...like a Tip Overlay? If so what did you use?? That seemes like a lot of Stress for a Glue Joint...without a Wrap of Sinew or String to help strengthen it....

nah man, look real close. it's inbetween the backing and the ipe, hence the hack saw. the tips were an after thoughts so i cut down between the back and belly, after that i clamped jusy beyond the cut, incase it wanted to split when the wanna be siyahs got wedged in there, used smooth on,shoved in the tips then when cured just shaped the tips and boom, done

try it! it's cool!

yeah similar but different, longer, higher angle and between to layers, so didn't need to have the large glueing surface. it does act like a recurve(because it is, kinda) like i said before the hand shock was minimal, and with the one i did in the other post about the scrap reflex deflex, was even less than this. there was some other factors i had to think about, now the mind set is, how can i make a hick long bow with static recurves, even after tillering, so when i get my fingers back i'm gonna play some more with it ;)
