Reflex/Deflex Bamboo backed Osage Tri-Lam build-a-long

We got the belly lams cut and planed down to 1/8". Cut the fades out on the riser. From the center of the riser I measure 2 1/4" from each side this gives me a 4 1/2" handle.Then from my 2 1/4" mark I I draw a taper down to the end of the riser.It will look like this

I lost a couple of pics when my batteries went dead.I t was showing how we fit the belly lams to the fades, I will explain it. First you want to make sure that you have a real smooth transition from your fades on to the center lam. Once you have that mark your belly lams 6" up from the end and taper them to about 1/16". I just use the belt sander. Then Take a couple of spring clamps and clamp the Lam on to the fades and see if you get a tight fit. You might have to sand a bit here or there. After you get a good fit,what we will do is take a heat gun to the lam while it is clamped to the riser so it will take the shape of the fade. It takes stress off of it and it also makes it easier gluing it up. When your ready to glue it up use the blocks that you cut from the fades and use them to clamp the lams in place on to the fades. We are going to make another one this weekend and I'll post the pics of it.

Here is a pic right after we had taken the clamps off it.

well i've been trying to copy you on this...got a few r/d blanks glued up (2 with hickory back, 1 bamboo...all maple cores) and shaped and attached the riser blocks. Yesterday I tillered one and shaped the handle...but left the riser most of its length...so it's way too long...and the bow only draws 30 pounds. I was going to pike it later today until i saw this post. Instead I'll recut the handle down to more reasonable dimensions, and then attach some belly lams to ride up the fades. I have many 3 foot slats of yew about 3/16 thick. So: you just taper the fade-end of the belly lam so it rides smoothly up the curve? I tried this once before,and got a failure where the belly lam met the tip of the fade: compression fractures and total bow failure...try and try again!

When we glued the belly lams on we left them 1 1/2" wide. Now I am going to trim it all up on the band saw, I stay about a 1/16" away from the bamboo so that way I can lay the limbs on the belt sander and sand it up to the bamboo.
