Title: How's she looking
Post by: deadsilence on July 17, 2017, 10:38:00 PM

64" ttt long bow. First time on the tree with a very tight long string. Shooting for an elliptical tiller and advice on where to remove. Sorry about lighting and picture but it is the best I can do by myself.

Looks like you don't have any fades, I would address that before bending.
Need a picture close up of the fade/handle area.

I would that you would have to show some pics of a drawn bow before anyone can advise you on taper or tiller...

3x Max...

If your fades don't get down in to the limb itself far enough the handle will eventually pop off. Probably sooner than later.

Fades are on the front in a power lam. Handle was 8" lam was 12". I had this piece of ipe left over and decided to give it a go. It is 1.5" wide and stays that way for 4" past the fade because I knew I need some mass to stop the bending, tapered down to .5" wide tips. I forget the thickness as I glued this up a while ago. I believe it was .5" with a taper beginning at the width taper going to .25" at the tip.  If you squint you can see the lams color changes.

The power lam may not suffice.

Sorry, but there are no fades...  Where your limb meets the riser I would call that a hard spot... It's a term in boat building...
   Its when stresses are not dispersed because of joined materials meeting at a hard angle...  Instead of working together they work independent of each other often causing weakness in the joint or failure...
   I would take heed of what Skeater said...

I'll still give it a go. It was all scrap stuff and you don't learn anything without trying. I will stay well away from the transition areas while tillering.

Just for reference this handle popped off on me.  I got lazy and didn't transition the fades enough.

You may be heading towards a break than the handle popping off.

You could remove most of the handle altogether and finish it as bend. Through the handle design.

I have to agree. If you don't cut that handle off and use a longer one and fade it into the limb,it is apt to break.good luck.>>>----> Ken
