Once the skins are glued on, I trim the LE with the hot wire. I'll add a balsa LE.

I've included a couple shots of my version of a Feathercut. It's just a pivoting arm and some pulleys to guide strings with clips on the ends that pull the wire through the cut. By adjusting the distance on the pivot arm from the pivot point to the strings you can control how fast one string is pulled versus the other. Once you work out the proper distances, you connect everything up, turn on the hot wire and release the pivot arm. A weight pulls the arm down and with it the hot wire. Takes a bit of fooling around to get it set up but it makes a very reproducible cut- much better than I could do by hand.
