I've started making some box calls out of some wood scraps I had around the shop. I seem to remember the bought-en calls had various methods of treating the edges of the box. I've tried chalk, but am wondering if resin might not work.
Any ideas?
A (soft) chalk works good for me.I sand the edge of the blades ones in awhile for better friction.
Try the resin and see if you like it
Blackboard chalk has oils in it that can build up and get slick. You can buy chalk meant for box calls.
You got my attention with the resin idea. What sort of resin would you use?
I wouldn't use a thing. You WANT friction. Chalks act as a lubricant. Just keep the wood surfaces clean and very lightly sand once in a while with fine sandpaper. You dont need a thing if the call is tuned and running proper.
One of my bought en ones is called "waterproof" and the bottom of the paddle and the box edges are coated with some sort of substance that works even when wet.
I was thinking of rosin like a rosin bag used by a pitcher.
Bak the rosin bag may work , applying it may be a chore . Depending on the wood used in a call , light sanding of the sound boards and paddle works , and or some side walk chalk . Walnut ,Cherry and Ash wood seem to work best for me .
