I got severely criticized by a few people who have nothing better to do and add nothing to this site when I posted those instructions, with pictures, so anyone can make their own parts. I even took a completed 2-sheave damper to homecoming, where it got virtually ignored. Now I build things like that for myself. If I can figure it out, it's not impossible.
