Dark verses Blonde  ??

How blonde is blonde(maple blonde, or light walnut)?
All the ipe I've ever seen has been dark brown. Apparently, the tree has sapwood, yellow/ greenish, grey, though I've never seen any mixed in with heartwood boards. Ipe is used mainly as decking and flooring, due to its hardness, and durability. A sapwood board in the mix would stand out badly, when laid out and probably wouldn't have the same resistance to rot, so I guess that's why you don't normally see it in a pack of Ipe at the timber merchants

I reckon sapwood would still make a pretty good bow though, its still dense as all heck.

Its light for ipe, but it doesn't look like sapwood to me. I reckon it will be good.

I was not very lucky with blond Ipe. I had more than one bow chrysaling away. I later discussed the topic with a more experienced bowyer telling me that it varies a lot. Blonde ipe generally is not so great, only the heavier boards maybe still ok. so you can be lucky or not. I would not stress the bow too much maybe. I personally will use my more pale boards for fencing now.   
density in general seems a good criteria for ipe, it goes along with quality (and also with color with the dark type).
I lately laminated a few warbows from different boards of dark ipe and noticed massive differences between the boards. the darker and heavier board produced a lot more drawweight at the same dimensions.

It's defiantly heavy and killed a new bandsaw blade in about 8" of trying to cut lams.

Bandsaw blades getting blunt. Yep, I remember doing that. A regular high carbon steel blade is no good for dense tropicals. You need a bi metal/high speed steel, or even a TCT saw blade if you have a large enough bandsaw.

Never worked with Ipe much but I know from the Classic when the guys are cutting tip over lays from it that it will toast a blade very quick, I try and get them to use the saw I use to cut out my knife blades. :) That stuff is tough for sure.  :)

I got the board (1" x 4" x 9 foot) at the classic 4 years or so ago. I cut it in 3 sections to get it back home, it was rounded over on the 4 corners for decking.
I don't know how to post pictures from imgur any more, just the link.  >:(

Hopefully it will work fine.

Mark,

In imgur you click on the picture you want, then click on the button with three dots in the top right and click on 'get share links'. This will open a pop down that has link options. I use the BBCode link to post in forums, you just click that link and then paste it in your post.

Be careful using ipe for tips. Horn is better.

No James.
But here's a few pics.
I got a little bored making these same elbs and was trying out new design options for heavier bows. Its a mixture of flatbow and elb - the crossection starts like an elb in the grip, then evolves almost towards a flatbow where it bends most, then going back to elb towards the tips. You can call it paddle bow, I call that design Bastard. Customers like it. Made them from yew and laminated IPE, up to 105#.
Cheers
