I tried a Norvise about 15 years ago. It is a great device, but just wasn't for me. Guess I'm too stuck in my ways. Anyway, I always wished I could "spin" dubbing as he does when tying an extended body fly.

Today, I tried my first extended body using a variable speed drill and a needle (and a bit of dubbing wax).

Now, don't let the finished fly deter you. It worked great, but I just don't tie many extended body flies.

I think I should have applied more pressure to get the dubbing on tighter as the needle was spinning. The point is, the procedure worked very well - just this particular tier's first attempt wasn't too good:
I think others will enjoy doing this.
