Default RE: Hot wire cutting tips?

this weekend we will make our first attempt at cutting out a wing based on the battle axe wing ..
Based on photos I come up with 30" wing half. 9" at the root and 6" at the tip. gonna use the airfoil below.
We are going to try a couple of methods.
One plan - attach the wire to a pivot point roughly 100" from the root of the wing. cut along the 9" root template. the anchored pivot point will control the other end of the wire. Adjust the pivot point so I get a 6" wing tip at 30" out from the root template... Will that work? I question how tight we would have to pull on the wire to make it follow the airfoil shape all along the wire? will drag cause the far end of the wire to "lose" its shape?

2nd plan is to attach a 9" template on one side and a 6" template on the other side and with one person on each side, drag the wire over the template...

having never done this we are trying to be flexable and will go with what works...

I'll take pics..
