Primitive Archer

Had a little more time tonight to work on the bow.  I was able to get both limbs down to a decent thickness.  It's bending a good amount on floor tiller at this point.  It's got some propeller twist and some funny bends in the one limb and a bit of deflex overall that will all need to be coerced out.  I'm hoping that dry heat will work to get it where I want it.

I was also able to save some bits from the belly removal by sawing through what I could.  Got a couple decent pieces for other projects.  I think I see an atlatl it one of them.  Just didn't want to waste it, might never get another chance to work with vine maple so I'm savoring it a bit.

Anyway, here's where I'm at now, and the salvaged parts.

Not sure when I'll be working on it. I'm in leather mode now. I'll bring it to the next Classic for your inspection and approval. 
 Good to see and talk to you at the Classic too.

Mark, have you talked to Roy. This seems to be his expertise.

Yes, I'm building off his form design and he gave me a stack height, I reduce the stack some because of the Ipe.
Same Ipe I gave you, any plan when you are going to build?
It was good to see and talk at the classic 

This is based in ignorance of this particular combo in an R/D bow, but I would say your ipe is too thick. Unless you are going to remove a bunch in tillering, in which case it is probably OK. You only need a thin layer of it on the belly to carry the big compression loads, especially with an osage core that is very good in compression as well. If you had a maple core then I would say maybe 3/16" ipe, but the osage doesn't need that much help and a 1/8" belly lam should be enough for the load and would keep the limb weight down for more speed.

It has to be scraped for tiller. Bamboo has nodes and some dips also.
BBI means Bamboo and Ipe, mine is a tri lam to keep the Ipe thinner.
If I made them all the time maybe I could get the Ipe thinner.

Congrats on the Elk Tags ! Way Kewl  Bob.
