static recurve build advice

[LittleBen]

Nice bow mike. What length are you drawing it to when shooting that 169fps?

[monterey]

28.5"  I need to get some iron from the weight set and check the scale.  Just not believing that 43#!

[monterey]

Checked my bow scale with a known weight and it checks out.  Will recheck the bow weight and chrono it again too.  Not sure of my memory on the speed and can't find the notes

[monterey]

Ok, first I double checked the draw weight.  It came in at 45.5# at my 28.5 draw.

chronoed the same 520 gr arrow three times with the following results.

#1....168.3
#2....169.3
#3....169.4

average = 169 fps

next came a 650 gr arrow.  Three shots.

#1....162.2
#2....162.5
#3....162.5

average = 162.4

Had a sudden impulse to try a light weight so nocked up one of the grandson's 375 gr arrows and got 209.4 fps.

Those are some serious numbers!  Loving the look of the sharp angles on those limbs.  Thanks for doing all the testing monterey! I'm sure a good chunk of us got some useful/applicable info out of that.

monterey
how far in front of the arrow tip (or back of the bow)do you put your chronograph

nice numbers

[fujimo]

that's is very cool mark.
 say, is there a standard distance for chrono placement?

[monterey]

Its four feet.

Wayne....I used to help Brent build the sheepeaters when he first "re-introduced" that style.  In fact I helped him coin the name.  

I can't remember the tapers...we did a lot of trial and error at first to come up with our formulas.   I can tell you that we didn't use any tip-wedges, just doubled up the glass on the belly side to make the static tips.

[monterey]

Mark, are you saying that the second layer of glass was applied only at the recurve point.

[Mark Baker]

Yep...from the tip, around the bend, then feathered to nothing.  On the belly side...

Mark--- the one I have has the FG tip wedge between the cores
Both cores are .002's
I got mine from Brent this year.

I put a .050 glass wedge in my BBWO as well thinking that it would help with not pulling the "curve" out, it did !!
