Straightening Bannana curve?
« on: February 13, 2008, 03:06:31 am »
Hey guy's. I had an excellent piece of osage that had about 5" of reflex in it from tip to tip and it was knot free and straight grained. It's a really super piece of wood but when I popped my center line it looked to be straight until I chopped the bow out and it has a bannana curve. This is driving me crazy!!!!!!!!!! Doe's anyone know of a way to remove this curve?

Is it dry?  In your situation, I'm usually getting it close to bow dimensions and then heating it. In my case I prefer using the stove burner and a little mineral oil on it till it gets hot enough to bend, and I will straighten it over my knee and go a bit past where straight it..Sometimes clamp it, but usually just hold it and then cool it off and let it sit for a day.

Other methods perhaps more popular here include a heat gun, and a form and you can heat it up and tighten the clamp as you go. And this works real good as well..

I just have this wild :o 6 year old so the thought of having a heat gun around make me a touch nervous at this point...

Like Rich said you can heat it and it will straighting right out.I use a heat gun and form
but if you don't have one you can do it as he said ,over your knee or clam it to a table or something.Did you pop a line or draw one down the center following the longitudinal grain ?
If you popped a line you may have some run off ,so you really need to be careful bending it
sideways ,it could pop out.Pictures would really help. :)

Thanks! i popped a line. I think I have minor run-out. The wood is very straight.

  They are scary Rich. My 6 year old grandson found my heat gun and wanted to burn ants and lizards. I keep them put way up now.

 If you have to pull the trigger, is it really archery?

Eddie, my wife used Pappy's heat gun to dry her hair at the TN classic last year. I kept expecting to see that 3' of blonde hair going up in a fireball.  :o

Progress might have been all right once but it's gone on for far too long.
