Good looking calls!
Brown Down and JPR28056, Misfire's right when he says Hut duck calls are the worst sounding duck call you've ever heard! Most duck call kits are that way. Some guys opt to just buy pre-made inserts from Echo. Those sound perfect.
You can get started pretty well by purchasing a "public" jig to make duck call toneboards. Most are in the $100-$150 range. Without a jig you'll never get repeatability in your inserts and you'll end up frustrated. Wade at Webfoot Custom Calls makes great jigs and also sells parts and pieces. He also sells a flat jig that gives you the cork notch and allows you to file your toneboards until you get the sound you want. When you get there, a custom jig can be made to your design for $300. Everything matters with duck calls. Reed material/width/length/angle, cork, tone channel diameter and depth on the toneboard, toneboard profile, exhaust diameter, etc.....A jig won't immediately give you good duck calls. It is a starting point.
