After cutting my core out, I clamp on my boo to the back and line it all up so I can trace off my limb tappers to my boo. I then cut out the boo to the shape of the core. I then check to see if I need to fix the tapper of the boo. Sometimes you get a side that is thicker because the boo doesnt line up exacltly perfect. I simply adjust the high sides and keep and eye on it with the caliper.
Now to get ready to glue up. I will do this bow with multiple glue ups.
First, I clean the Ipe with acetone. Ipe is oily wood, not quite as bad as cocobola, rose wood, or blood wood, but still oily. I have found that it is not too oily to use titebond III. Which is good because I wont have to use a two part epoxy and bake it. Not quite as messy either.
After cleaning the ipe, real good, I use painters tape to mask off the belly of the core. I dont want to get it messy because ive got it all smooth and even for the later glue up. I also mask off the back of the boo. Just so the clean up is easier.
I now transpose mycenter markof the core, power lam, and boo to the edges so I can see them to line them up when I start the glueing.
I put the core in my vice, back up,and lay my power lam down, belly up, as well as laying the boo down belly up. This way everything is ready for glue and easy to access.
I spead a coat of titebond on the core and smooth it out with a popsicle stick, same for the bottom of the power lam. I then put the powerlam on, lining up the center marks I made on the sides. now spread a coat of glue on the back of the power lam and the belly of the boo and put it all together. Agian, keeping an eye on the center lines. I clamp the middle with a spring clamp to hold everything while I wrape the thing up with an inner tube. I use inner tubes for strech clamps.
