Title: Heat straitnin question
Post by: Rick Wallace on March 03, 2012, 04:13:49 pm
Workin on my trade bow today,,Its a pecan (pee-con) stave, I needed to straitin one limb,I got it hot(heat gun) pulled it a little more than where I needed it and clamped it in place. How long should I leave it there?? I dont have much experience at heating. Right now its in the 60s,100% humidity  if that matters.  ???

I leave mine clamped over night.  Some people just leave it until it cools off.

clamps and a form for reflex/treating/lateral straightening.  for twists i attach a clamp onto the limb and hang weight from a string or rope while on the form to avoid changing the reflex.

2 small 2x4"s on a bench then use a clamp to pry the wood at the bend...slightly overbend it it will try to spring back.

For straightening I use a 4"x4" piece of fiberglass angle about 5 1/2' long.  It's lightweight but plenty strong enough to clamp a bow to.  I bent a couple of pieces of aluminum flashing to fit over it.  I slide them wherever I want to heat the bow at.  It helps to reflect the heat into the wood.  I used to just clamp the bow in a vice and hang a weight from it.  With the piece of angle, I've cut the heating time by more than half and I can make more precise corrections.
