REFLECTOR: Novice question

Hi All,
Helping build 1 set of wings and having built my set I can suggest the 
following....
(and we tried every thing we could think of and found the following to be 
the best method)

1) The more you handle the triax the worse it gets.
2) only pull the worse ones and just pull till the almost are straight or 
just barely straight - not too much
      - the harder you pull the more curved the triax will get and trying 
to "fix" will only make it worse.
3) Dont pull every fiber - only the really bad ones.

The process is really not too bad.

SO - here is what I did and it was pretty easy.
1) We put a rod ~1" (from home depot) between 2 ladders (weighted so the 
wouldn't fall over)
2) placed the triax roll on the rod between the ladders at the end of the wing
3) Prepare the wing.
4) with the help of 2 or 3 people- pull/roll the triax directly from the 
roll onto the wing - keeping it off the wing as long as you can ( ie-use 
tallish ladders)
      - handle the triax as little as possible as the more you handle it 
the worse ( more squiggles) you'll get.
      - right off the roll it's pretty virgin.
5) pull and major squiggles until the are bearly straight -not too much now...
6)  - complete wetting out the layup.

We used this procedure and it worked very well. Very few squiggles that 
needed worked very lightly and only major ones.

Hope this helps... and welcome to the 'wing builders club'

Thanks,
Kevin Baker
