Good idea using a fan in the bow oven, might have to add that to my setup

Ok. The limb/riser issue??? I don't like how the limbs sit way out on the riser.
Ooo! I was looking around in my scraps and found a really nice piece of Bubinga that was left over from building his son's bow!
I'm going to use it to build up the riser and "move" the riser profile forward and make the transition from limbs to riser smooth. I'll post better pics of what I mean when I start shaping the riser and attaching the limbs.
Cool! More Bubinga...limb tips! This is cool, it will make a special connection between the two bows.

The paste wax in the earlier picture, put it on the form just incase some epoxy gets on it. The wax makes the epoxy come off the form a little easier. But, be extra cautious to not get any on the limbs it will really mess things up! I wear gloves when I put the wax on the form, toss them and put on new gloves before I even think of touching the lams.

I kinda feel like a little bit of a tease. The next steps for me are so messy with epoxy that it is hazardous to the camera. So, very few pictures. The limbs are built up from a fiberglass lam, then a tapered, a parallel, a wedge, tapper and then a fiberglass lam. Apply epoxy to both surfaces of each lam, except the outside of the fiberglass. Now we have several long thin pieces of wood and fiberglass covered with slick epoxy. Try and hold them in place as we put them into the form. Fold plastic wrap over them and use strapping tape to hold them down until we get the top of the form on and fastened. Sometime we need to use some clamps to get the form closed. Then we add 60lbs of air to the air hose.
Everything placed in the hot box.
Throw a few old moving blankets over the hot box to help keep temps up, and let it cure for 8-9 hours. After that turn off the hot box and LEAVE IT CLOSED!!!! This is tough!
We must let it cool on its own time, don't rush it. I usually try and let it have several hours. So, overnight we wait. I work tomorrow but I will do my best to get some pics before I go in and try to post them tomorrow night.
That's it for today.
