RV-4 HS Jig - Free for the taking
I'm not sure anyone is even building -4 tails anymore, but I have a Horizontal Stabilizer fixture that anyone is welcome to take.
My fixture is similar to what Van's shows in the instruction manual. It's built from 4x4's and tied to the floor and ceiling in my basement in Bolton, MA.
I can provide photos if desired. I'll be done with it in January and if no better use is found, it will become firewood.
