That riser is looking great. I can't wait to watch this one come together.

(Just click these thumbnail photos to see the larger image)

This may be too many photos and too detailed of a build along, but you can simply click on the photos you want to see and pass over the others.

Here's how the riser looks after I planed it to 1-5/8" in thickness. I flattened one side on the jointer, then planed the other side parallel to it on the thickness planer.
Image
Tracing the template.
Image
Extending the curve of the riser back off of the blank.
Image
Cutting the riser back glass overlays with a dremel tool.
Image
Cutting the riser back profile.
Image
Grinding the profile to fit the template and the pressure blocks using my cheap spindle grinder.
Image
Checking the fit of the pressure blocks.
Image
Dry run of the overlays, blocks and clamps.
Image
Checking for gaps between the overlays and riser block. There is a little gap here. Going back to the grinder.
Image
Now its better.
Image
The riser and overlays all organized in order to be glued.
Image
Glued and clamped. I'll leave to dry overnight. No heat.
Image
After gluing. Looks good.
Image
Cleaning off the squeeze out on the spindle sander. Note how I keep the grinder at a slight angle and off the sides to keep the block parallel.
Image
Flatten the sides ever so slightly to get the remaining glue off.
Image
Block sanding the center of the overlays to rough up the surface for gluing on the second layer. I glue them on in two steps like this because it just works easier for me in pressing them down evenly.
Image
Rough it up a bit more with the spindle sander.
Image
Brushing off the surfaces in preparation for gluing.
Image
The second layer of overlays organized in order of gluing and ready while I mix up more Smooth-On.

Dry run of the overlays and pressure block. I forgot to mention previously that I insert a 1/8" rubber pressure strip between the overlays, plastic and pressure block. This lets the pressure even out a bit during the glue up and helps eliminate gaps. I have found that just pushing harder doesn't always help eliminate gaps... grinding for a better fit always works better with less pressure.
Image
Glued and clamped...let this cure overnight.
Image
I usually start the riser first like this and do the gluing at the beginning of each work session. While it is curing, I will start the slicing of the lams...lol.
Image
Sizing up the boo flooring.
Image
Resawing the lams to about .100 or so. I'll grind these later to .083" at the butt later.
Image
Image
Image
Also cutting and grinding the decorative hardwood overlays for the limbs... butts and tips of the belly side. I picked out some nice figured black walnut to match the riser stripe and outer overlay. I'm thinking about putting a piece of osage on the limb somewhere but haven't decided where it will look good yet.
Image
Cutting everything to length on the cut off saw. Note how I have this piece of wood to hold the thin pieces down so they don't shatter and fly into little pieces. Been there.
Image
Cutting and grinding the wedges. I'm making some parallel wedges on this bow...a first for me...I've been making them straight tapered but have been wanting to change to these. I'm guessing on thickness... I'll make them the same thickness as the old ones on the end of the riser and the same length beyond the riser as the old ones.
Image
Image
I made this taper sled real quick and simply guessed on the ramp...wow, it came out perfect.
Image
Image
Image
The grinding of the lams. I'm using two .001 core tapers and brown glass. I should mention that I always put the unground stack far away from me and then put them in a closer stack after I grind one. I run them all through at one thickness, flip them over and grind them again, then tighten it up a bit and run them through another pass. This way, they all come out the same at the end.
Image
Grinding to .083 at the butt end.
Image
Image
Back to the riser. All cleaned up and profiled to rough shape with the spindle sander.
Image
Marking the limb mounting pad angles.
Image
Cutting the angles as close to parallel to the outside of the line as possible. I used an old blade on the old saw to go through the glass, then cut the wood on my new saw.

I'll post the rest of this batch of photos later... for now, I'm going down to the shop and try to get the riser done. Jim

Kirk, they are called "clickable thumbnails" at Photobucket.

TJ, the riser back overlays are (from riser outward)... full-length overlays: .030 coretuff white, .040 black walnut, .040 clear; short center overlays: .040 osage, .040 black walnut.
