Can I make a bow from this Ipe plank?

How true. Yup your gonna lose some weight as result of correctin the hine but you oughtta end up with a pretty good shooter.
  I myself just came across some tigerwood( ipe/teak family) from a deck im working on. So i am glad to see your plank turned out pretty good so far

Thanks guys, after a couple more hours this evening I think I have it.  Of course my camera picked this particular time to go on the fritz or I'd post some pictures of the outcome.  I did end up losing about 8lbs off the draw.  It's 57lbs at 28".  I'm happy with that.  

As for the mystery of the hinge, that would be my error.  I overworked that area, or rather I worked it and worked it to get some bend, no results, then really really worked it and...well hello there hinge.  The are of the tiller is going to take quite a few more bows to get a better feel for it.

This is my first decent all wood bow and I'm happy as a pig in slop over it.  Can't wait to shoot it   .
