Its only an inch so far, I don't think it will turn into a magic bean stalk. Is this common with all ipe bows? I would imagine it is. We  will see how muck it keeps after its shot in, then ill know how much to glue in on the next one.

I've made three Perry reflexed bows and they all gained reflex in the early stages of tillering. I know one of them stopped gaining at about 20"(draw length) and then started losing reflex(set?). I think it gained a couple of inches and then lost maybe one. Still a net gain.

Well guys she is dead, but she went out with a bang. Took ten minutes to find all the pieces. I'm sure I done something wrong, it was only at 45 pounds went it went  and 1/4 inch thick were it blew on both sides.. I had pulled it to 55 on the tree while checking tiller many times. So I'm thinking several things.
1. My reflex wasnt smooth enough, it didnt look abrupt or all in one spot, but it could have been more evenly distibuted.
2. That backing felt awfull dry, I used it any way. Wasn't crazy about the grain either.
3. That ipe looks really dry on the inside for a tropical wood. Ive worked with other oily woods like mahogany and teak they never look that dry when you split it.
4. Bow gods mad at me.
But both limbs went simultaneously in the exact same spot. Right before or almost in the most acute area of reflex. there is also a swirly spot in the grain there but only one side. I'm thinking this was my screw up.

Looks like your grain configuration was off in both pieces.  The appearance of the Ipe being dry is typical despite it being oily.

Yup, if I can see what I think I can see, it appears you have some severe grain run-off on the backing.

How was it off? I have another piece that's identical.
Also I pulled it way further than I should have after switching trees. A good 5 inches, so that most likely done it.

Yet. The true measure of bow quality wood isn't attained until you've ran 2500-5000 arrows through it. That's when the cream rises.

The first one I used successfully was hickory backing I got from three rivers I believe. This one came from a local guy.

John, the ipe followed the grain where it broke as did the backing.
