Sort of inspired by the south indian composite bows that are boo on wood core with horn belly recurves. This bow has boo back, fully tapered and tillere osage core, and thin ipe lam on belly. Its 62" ntn, 58#/27". Its 1" (2.54 cm) wide at the fades. It has brown osage tip overlays and handle built up from 1/8" ipe strips. The osage core is a bias grained slat of some very light density stuff with thick early growth. The ipe strip was supurb piece, flat sawn with a continuous ring across most of its length. 2 runouts. Finished bow weighs only 14.5 ounces (413 g).
I pretillered the osage slat, steamed in some of the curve at the ends, backed with the boo. Tillered the bow out to about 40#, about 9/19" thick in grip area. To get the glueing surface on the belly, I sanded it with a sanding block perfectly flat. Here I discovered my first glitch. One tip was miss-aligned a bit throwing the string off center. I glued the 1/18" ipe strip on with TB3, and set up a form to pull the tip over. I wish I had taken the backed core down to around 30# and sanded the ipe strip down to 1/16, because I had to remove so much ipe and essentially re-tiller from scratch. Ipe ended up very thin. Started last Oct. and have been fiddling with it all fall and winter. Awesome to shoot.

I love the design of that bow. The tiller looks great. Justin

Fine work!

Thanks. I forgot to finish the story about the alignment of the upper tip. After belly strip glue up, it was still off, pulling to the right - bottom limb is shorter, so I couldn;t reverse limb placement. I strung it and gently persuaded it into position by hand, and it eventually worked.

That looks good Dave! I need to try a laminate of some kind :).

What a great bow Dave. I'm amazed at how much strength the ipe added.
-
Nice bow, really beautifull lines.
-
very cool bow. ipe makes a great bely. I fixed a hickory bow by putting ipe on the belly. The ipe was really thin when I was done also but it didnt seem to mind.

Dave, Looks like your persistence paid of nicely. I like the profile, and had been thinking about that combination as well. It has to have good "numbers". I have bellied a couple bows with ipe which doubled the poundage and increased the mass by less than a third so there are some good benefits to this technique..

Boy, its a bit labor intensive though. The belly strip glue up paticularly. I had it on the first time and didn't like how iit was looking and yanked it off half way through drying. Had to sand it all of again, but the second time was the charm. I wrapped it at a few strategic locations on the handle and limbs with fine hemp cord to suppress any desire to delaminate during tillering.
