Nice thread.Looking good.
I've always liked this model Kirk, I am absolutely stealing this captive bolt system one day when the skill catches up to the brain.
One question for ya, how are you keeping your captive bolt glue-free during that overlay, I see you line it up with the Allen, is that enough to keep the hole clean?
Doing the belly ramp caps where that T handle allen wrench goes through the overlay requires pre drilling the overlay on an angle like this with a 1/4" hole. Then lightly knock the sharp edges off with a chain saw file and sand paper before you glue it up. BTW.. its best to laminate your finished overlay to a piece of phenolic on these belly ramps. You can pull it off ok without the phenolic using ebony or other serious hardwood. But with walnut or curly maple, the phenolic protects the hole edge where the allen wrench is inserted. Learned that one the hard way....

I use a thick super glue to apply these overlays and just keep the glue application away from the hole. But ... you need to use the allen wrench shank to center the hole up while clamping it. Its kinda tricky until you've done a couple. They like to slide around a bit... when you got the clamps on, Then you turn the allen wrench a few times to make sure you haven't glued your bow bolt to the retaining sleeve. Making sure the overlay material is a bit long is another trick.
I'm doing the final back overlays right now that cover the back of the riser and the T-nuts that hold the limbs on. This particular bow has the book matched riser block that accentuates the grain. i ripped some of those book matched pieces from the riser block before milling it, so i could use it for overlay stock. I Typically cut these overlays from one piece of wood, and do 3 overlays, and grain match them where the limb butt overlays meet the riser. This gives the illusion of a one piece bow. But this one i got a little fancy with. I'm doing 4 separate overlays instead of 3 and book matched the book matched overlays. It's a bit more work, but i think its going to look pretty amazing when done.
Considering Rob is a luthier, and also does some amazing gun stock work himself. i think he'll appreciate the extra effort and craftsmanship needed to pull off a double book matched overlay. trying to keep all this lined up straight and the joinery tight is easier said than done.
The grain in this wood is pretty cool...... Stay tuned for the final procedure and see the finish product.... i'll post a few more pictures in the build album later today, or tomorrow.

Thanks, will stay tuned
