angular experiment
« on: June 19, 2015, 02:55:07 pm »
Last time I have made intresting experiment on angular d/r shape. This time more deflexive design, long static grip. On heavy arrow nothing special 9 GPP - 175 fps. on 8 GPP better - 185 fps on 6 GPP - bang- 226 fps. I must check it one mor time in other light I have 217, 226, 227 fps read with fingers release. 46 lb , yew, ipe, bamboo. Mass 700 gram - grip mass about 450 gram , 250 gram working limbs. Heav grip make bow stable and give better shooting comfort.

that's a slick design, and seems like it's a fast bow too :-)
Let us know when you do some flight shooting tests with it, I'm curious about that too.

  That would make an excelent flight bow. Very good speeds at 6 grains per pound. 6 grains per pound will also carry very well for distance. I have a little flight bow I checked at 3 gpp 4 gpp and 5 ggp    at 5 I am getting about 225, at 4 around 250 and at 3 as high as 282 fps. I cant get the 150 grain arrows to carry very well though, just not enough mass.   250 grains is about the lightest I can get consistent distance with. Lighter than that it is hit and miss and very sensitive to how cleanly it takes off.

Nice... what's the length of the working limbs?

Beautiful! That is a really fast bow! I'd love to see some close-ups showing the boo nodes, and the handle.
