build along for my bro

This is a bow I built for my brother in Oregon. I started by making some rough sketches of how I wanted it using some cut outs from previous builds.
Image
Image
Image
I had a full panel of grey action wood, I made some cuts for my riser and wedge set, I then ground my wedges on my sled first into tapers and then made them into parallel wedges.

I then took some action boo flooring and ripped off the tongue and groove and them ripped them down to 1 ¾” wide on the table saw.
Image
Image
Next I resawed some a-boo and action wood rough parallels on my band saw.

The next step was to come up with a laminated veneer to go on the belly and back of the limb. I started with action wood split with a-boo and maple.

After the glue was cured I ran it through my drum sander and resawed it in to 5 lams, I ran one practice down to see how thin I could make them, I brought them down to .015”

I then received some materials to start the I beam of the riser.
Image
I started with a 2”x2”x20” block and cut it in half length wise and ran I through my drum sander. I also ran my phenolic through the drum sander.

I cleaned all the parts with compressed air and glued them together. When cured I re ran it through the sander.

The next step was to make the I beam into a double radius curve.
I ran a test piece of boo to set the radius on my band saw swing jig.

Once cut I sand with a 40 grit block by hand. I then glued red phenolic and I think 4 parallels of .125” action wood and black phenolic to the back of the riser and glued it.

When it was cured it cleaned it up on the drum sander and added another 5 .125” parallels to the back and glued it up, when it cured I ran it again through the drum sander.

I then was ready to cut the second radius on the belly side of the riser.
Image
Image
After cutting it on the swing jig I hand sanded again and added one more strip of red phenolic and another stack of .100” parallels, the .125” would not make the tighter radius.

I did not get any pictures of grinding the lams but I used the same drum sander with my dedicated 60 grit lamination sand paper. The stack up from belly to back goes. Clear glass, veneer, .002” per inch a-boo taper, action wood wedge, action wood parallel, veneer and clear glass. I used compressed air only to clean the lams.
