Looking really good, it's about there. A little positive tiller is good. The first few inches out of the right fade might be just a bit stiff, or could just be my eyes. I think Pyramid bows should bend more in the wider inner limbs and be a bit stiffer midlimb-to tip than tapered limb bows (more bend where there's more wood). But then again I haven't made but two pyramid bows, so take my advice with a grain of salt.

tried to get the bow to bend mor right after the fades;
here she is
45#@29"
2nd picture is right after unbracing after shooting.

i just found the bow developed a FRET but NO CRYSALS!
shot the bow quite a bit and pulled it 50 to 100 X's per day for almost a week now; the bow shoots good, the tiller didn't change a bit and i have half an inch of string follow right after unbracing. this afternoon i found the fret and didn't know what it was. sanded it off and it came back after pulling. shot the bow again, no further problem, fret stays same size!
the fret is almost not visible so i marked it exactly with pencil.
anyone seen this before???
thanks for any replies!!!!!!

Compression fracture, same as a chrysal, fret, same thing different words.  I'm guessing it is right about where the silencer falls on the last pic on the tree, right limb about 8", 10" out from the fade?

I rarely experience compression failures (humid climate) but that's exactly what they look like. 

[medicinewheel]

yes it's bit less then 8" out from the fade but on the lower (pictured left) limb!
well than probably not much i can do about it, right?!

Frank shoot it anyway I have an ash bow with lots of frets, I thought it was a gonner but its still shootin fine even with several thousand shots on it.

[DCM]

By all means shoot the bow.  Liable to not make any difference.

Frank,
a nice topic and a nice bow.
Shoot the bow - I have the same problem (frets) with a hickory backed maple ( may be the hickory is to strong/thick for the maple), but the bow shoots and has no visible stringfollow.

Very nice, I've always liked those pyramid bows.

guys i was just kidding a little; the bow DOES shoot great and i really don't believe the fret is a mayor problem - looking at the tiller i think the lower (left) limb might still be a little bit too stiff...may that be the reason??
the hickory - maple ratio is 1 to 4, i don't think that's too bad.
yes sean, i like that design, too...it's so pure somehow!
this weekend i'll stain the bow and make it look really beautifull. more pictures later!
