one piece static tip build a long - full draw! finished! tested!

About 14" of tip movement to brace, this bow is no joke.
70#@29" sounds about right. I measured 60# right at 26".

Anyway you can see the testing has already begun, shot the first few arrows through her today and it's definately got some cast!
Can't wait to do ALOT more shooting with this bow, and turkey season is right around the corner. Can't imagine a better bow to shoot from a hunting blind.

In case you haven't figured it out, Wayne decided what this overweight bow needed was someone who wasn't going to draw her so dang far! So without warning this baby arrived at my door with instruction to "shoot the crap out of it" and give some honest feedback. Couldn't be more stoked.
Hopefully more testing and pics to come.

Currently plotting how to determine the expected gains in speed with decreasing tip mass .... That is without actually having to figure out HOW to reduce tip mass ...

Great bow!  Mark's first prototype ended up here, cause it needed a longer draw to bring out its beastly side (which it did!)  Easiest way to get thin tips is laminated 'boo, I think.

(Quote from Pat B on the other forum)

It's in the bowyer's bible 1
   On my bows I leave the tips thick(ending up with 1/2" or just under) but narrow them to 3/8" or less. Wood thickness is 8 times stronger  than wood width so you can eliminate lots of physical weight by keeping them narrow but deep.     Pat


My tip belly is 1/2" wide taper to 3/16" at the nock
My tip backs is 1/8"ish wide for most of the tip
My tip thickness is around 1/2". my tips are much longer than that Recurve from Fujimo
phenolic and fiber glass are heavyer than wood
so I use sitka spruce as much as possible


This tip is not completely finished, the last 2" will be tapered more.
   

Not having string groves AT the nock you can make it narrow
My string loop is 2" long and there is a hint of a string groove half way between the nock and the bridge

   
ALL OF THAT TOGETHER MAKES A DIFFERENCE
Because of my shoulder, My goal is to make a low poundage bow that is fast.

A 25# @ 28" bow shooting 170/180 FPS with 10 grains per pound.

My need for speed has become an obsession.

I'am making a one piece now with more reflex than my others. Center shot makes it better too.

Just how fast is the fastest Traditional bow???????????????????????????

Ben, i got a lot of info from Mark while i was building this bow, the main difference between what he did on his first bows and what i did was- he put his spruce on as overlays, and i put mine in the core- kinda like a tip wedge- on steroids    :D    i considered trapping the back of the tips very aggressively like Mark did, but my real concern was then i would be narrowing the back glass too much- and would lose structural integrity. where as with the overlays, the spruce could be trapped hard- and there would still be significant back glass remaining.
just my interpretation!
as i said, the phenolic could go a bit thinner if needed- that was the only phenolic i had- in hindsight- i should have put it through the thickness sander, and thinned it down a bit- but it does make for more material for the longitudinal string groove along the belly.

maybe the way to go is like mark did, the asian way- with a more positive nock tip, and no side nocks, and bigger loops on the string. i wonder what that would do to the performance- because one would have a slightly lower brace height for the same braced profile- with the string sitting down the statics a little ways

my fear with the tips getting too narrow was twisting and stability- i only used plain ul glass- no bi-axial or even uls. just what i had.
cheers

is your draw more like 26" , if so you could trap the entire bow to drop a smidge of weight if you needed too.
or you could just cut it lengthwise down the center- make two kids bows, and send one to Roy
