Here is what the riser block looks like....
Got her milled, hardware installed, & Ready to mount limbs, ground the lams and power wedges, and i'm ready for the first limb lay up...
I started a photo album for the build so its easier to post progress. Kirk

Looking good so far Kirk
I like that you are stepping outside of your comfort zone.
You are guessing at a stack for the first layup??
Show all your "failure's" for hitting your target # please
That’s the fun in this one Max…. The stack height is a total SWAG at this point. I didn’t even reference my bowyers log. It looks pretty beefy without glass, and I decided to use a double power lam for my wedge system rather than a solid wedge.
Doing this should lengthen the working portion of the limb and help distribute the load over the full limb length more evenly, which is common with self bows and board bows. I’ve also left out the tip wedges I typically use with this limb design. I figured I could always use external wedges and add them to the belly side if needed.
Once I get this set strung up, I’ll set up my video camera and we will see what happens. I think this ultimately is going to boil down to comprehension testing this fossilized bamboo belly. I ran a couple .002 maple tapers in the core and used thicker parallel fossilized bamboo lams belly and back for tiller adjustment.
The density of this particular resin impregnated woven bamboo is off the charts compared to any other bamboo I’ve used. So I’m thinking this will be the ultimate compression test.
I thought briefly about using IPE on the belly, as it’s a known commodity with Tri lam wood bows… but I figured what the hell… I’m going to give this new stuff a go.
Stay tuned…. Lay up today, fireworks tomorrow…. Kirk
