Reflex/Deflex Bamboo backed Osage Tri-Lam build-a-long
wytetale:
I ended up taking to much off in the mid limb area, and not enough in the last third. I wanted to leave the tips fairly stiff, but not that much.Sometimes when your tillering everything seems fine. You stop come back to it and you see something different. When I posted this it was the first I saw the pic and could really see how much it was bending in the mid. What I am going to do is start to get the last third of the linbs bending more.
wytetale:
Did a little more work on the tillering. Got theouter third of the limbs bending a little. Looks alot better, lost 5# doing so.45# at 28" now. The whole key to tillering I think is getting your thickness of your lamination or your belly wood at the proper dementions before you glue up. This one was way to heavy to start. The demensions I used worked fine for a 66" bow, but for a 60" it was way to stiff to start with. The more wood you have to remove and the more you have to tiller the more you have a chance of getting a hinge or fret in the belly. Probably should of had a taper of 3/16 to 1/16 on the mid lam and kept the 1/8 on the belly. That will be in my notes for the next one.

Tillering is done now to lay out the handle, you can lay it out on the bamboo before you glue it up and cut to shape then, or like I do I do it after everything is glued up. I draw a centerline through the handle length wise. Find center of the bow and mark it.Next I measure 2 1/4" off each side of center. That my handle. From center again measure 4 1/2" off each side that will be the end of the fades. At the end of my handle marks I mark the width on each side 1" overall. Then draw my lines in. Should look like this.
Then cut it out
Now to cut in the shelf, word of caution make sure you mark the top or bottom limb, I have cut the shelf on the wrong side already, you either have a lefty or you have to go back and retiller it to switch the limbs from top to bottom. I measure 2" up from center for my shelf, Then I go 3/8"deep and taper up 3" for the sight window.
wytetale:
After the shelf is cut out I will measure down 1/4" and draw a line across the handle and then draw a radius on it. Then I will mark the handle. and cut it out.
wytetale:
Now for the fun part shaping the handle. Everybody has there own way and shape they like. My dad does a lot of bird carvings and two dremel like tools that run on a cable. one is set up for taking the bulk of the wood off and have the other set up with a sanding drum. It takes me a bout 15 min to cut the radius on the shelf and to shape the handle.
