And here's the finished product:
I went with a "timber rattler" camo pattern.
After that, I refinished the whole bow with several coats of satin spray on poly.
I also filled two holes on the other side of the riser. You can't see it in the pictures, but I didn't have any way to match the wood, so I used two 1/8" brass pins and sanded them flat.
There is a little discoloration around them from where a sight was installed for a long time before I got it. That's really the only blemish on this thing. I probably could have gotten the discoloration off, but I didn't want to sand all the way through the original finish.
The timber rattler I killed wasn't quite long enough, so I split it down the middle and used two pieces. Where they met at the grip wasn't very noticeable, but it was visible. Plus that is where it will receive the most contact and potentially wear or get pulled loose, so I decided to install a leather grip wrap to protect/hide the ends of the skin.
Overall, I'm happy with it. A big thanks to the guys over on the bowyers bench for instructing me on how to get this done. As always, this is a great group of guys.
