On the chrono, nothing really.
On the build, I learned to make a jig to cut it on the table saw, and a jig to hold the bow lined up while wrapping.
Don't use too much release agent, just enough.
It came apart well, I used toothpicks to keep the holes lined up, a whack with a hammer to a block clamped to the bow and it was loose.
The auto body glass ckoth worked fine (so far) I don't forsee any problems with it.
Put something with color (cotton cloth was reccomended) in the wrap after you have about 2/3 of the wrap on there so you don't get too deep. I got lucky on that one...
Make one, they are cool!
