Nah....that's easy peasy     :knothead:   [/b]
you know..it might not be THAT bad.
I'm not positive I can do it..BUT
I couldn't help myself..
I had a barrel that fit in for a riser pretty good and flexed the bow just a bit..just an inch or 2.

Looked like it just might come around in the right places...we'll see..

First I gotta get a handle on the thing...my least favorite part of the build...just don't have good tools for that...or a steady hand.

The plan is to try to layer a few 3/16" thick pieces in with glue and c-clamps.
Worried doing so might try to straighten out the bow in the handle area. Might try to do it on the glue up jig so I can hold down the dips. If so, i'll pad the heck outta the back there.
Just gotta try it and see how it goes....maybe just glue on a few pieces at a time..I dunno

Here ya go Bob.
Sorry it took so long.
I hope this makes sense.
Might wanna wait till after this one is done or broke before ya start...lol. This is an experiment for me and my 1st tri...

The angles on the ends are 5" high
The center angle is 3" high
The mid pads are .5" high

Now, Each of the above pieces are set on the 2x4 tube. The ends have the tube set tall, the mid limb pads and the center have the tube set low.

So the final heights off the base are..
Ends= 9"
Mid limbs= 2.5"
Center 5"

Spacing is...
 center to center of mid limb pad=14"
 center of pads to ends =15"

Things were looking really nice on the very taught string with the tips moving 9"....maybe a little more
Moved it up to about a 2" brace string.
flexed the tips down about 4" and BOOM!
Didn't see any signs of a hinge at all.
The worst thing is I have no idea WHY.
The hickory backing broke almost straight across in 2 places 9" or so apart...about mid limb.
The walnut core "tore" diagonally in between the breaks.
The osage belly splintered a little but not much.

I think I must have just been trying to get the mid limbs to move too far. They had to come around a lot just to get it to brace.

I think I must've created a hinge though it looked about perfect to my eyes. The limbs were flexing slightly at the fades. Tips were barely flexing. The midlimbs were almost straight at brace. Basically at brace  the limbs looked darn near straight off the curved riser section with just a hint of the tips pointing toward the back.I was just starting to get thinking..this just might work out..LOL
