I started building cranks to make something different than was on the store self. I like smaller sized baits and did not like what was being sold in the big box stores.
I made my first crank with a coping saw, pocket knife, and sand paper. The bait was made of cedar and painted the belly orange and back black. I caught somewhere around 40 bass on that bait and I've never stopped. I use a scroll saw, drill press, compressor, and airbrushes now for building. I still do all my carving/sanding by hand (my fav part of the build). I have no artistic ability but I'm stubborn so I keep trying until I figure out how to paint a pattern I like. The trick with painting is simple, lots and lots of practice.
