Bear Paw Fletching Jig - Hints & Tips?

[SteveMcD]

I bought a Bear Paw Fletching Jig (Left Helical) a while back, It seems pretty straight forward, but the directions don't tell you much.  
 
Anybody have any experience, hints or tips regarding this jig?
 
Appreciate any feedback.

I agree the directions are sparse. However, I think the jig is very straightforward and I have been getting way better results from it than from any others (including the Bitz) with far less fooling around. I think, loosen everything up, put a feather in the clamp and get it where you want it, then retighten and you should be good to go from there on out. It's bigger than I thought it would be.....
