I've been looking to do this too. The first problem is the design. How thick to make the laminations and whether to taper them or not. oldfatguy apparently ran into that problem too.

Bingham has a chart on their website of thicknesses for various types and lengths of bows.

A well tuned bandsaw is the first step, but you have to have a way to make each layer exactly the same thickness in both limbs. This is where an overhead sander is necessary. You don't need one of the expensive machines. A drill press or table saw can be set up to do this, but it takes really careful adjustment to be sure the lams are square and parallel. Also, I've seen some home made sanders that work well.

There are a couple of glues that most bowyers use. Smooth On epoxy is the standard.

There are some videos available on this subject. If you don't want to buy them you can rent from Smartflix. There are a lot of videos on youtube too.

Related to design is your form and clamping method. Several videos show how to build this. It has to be pretty precise and match on both ends. And you need the right amount of pressure to be sure you get good adhesion. Too little & you get voids in the glue layer. To much and the glue squeezes out (glue starved joint). Both will lead to failure.

After that comes the hot box for curing the epoxy. Poor Folks Bows has a cheap one that works well if you are not trying to set up for larger production runs.

Bingham also has inexpensive plans for several types of bows.

Hope this helps,
Allen
