My son and I made a hot wire cutter today and started trying to cut some wings. I had the templates for the root and tip on each end. But keeping the wire in sync so that it reached the ends of each template at the same time was really hard. Ended up with some weird leading edges! What happened was one end of the wire was on the top of the leading edge, the other side of the wire was already around at the bottom making for a 'sunken' edge.
Is there an easy way I am missing, or do I just need practice? In my mind it was going to be so easy... :P
