What are you guys using to make these calls? Are there direction or how to guides on what to do and what machinery to use? Any info would be great as I would like to make my own as well!
I have used Cedar, poplar, oak & mahogany so far.
My opinion is the poplar has the best overall sound, a higher pitch and can be made to sound clear or raspy. The Oak did not make a good call box, however if you put an oak paddle on a cedar box, it sounds great. The cedar makes a lower tone call, I don't really care for the lower tone, but it does sound good if thats what you like. If you use cedar, care must be taken when creating the box. If the box (inside cut-out) is too wide or long, you lose all tone and pitch. For good quality sound and ease of working with the wood, I prefer poplar.
I've just started with Mahogany and really can't give an opinion yet.
As far as information on making calls, just google "box calls" and you will see several sights. I make all my calls out of solid wood, no glue or joints (nothing to come lose). I use solid brass screws with a recessed spring. I don't use a router or any fancy wood working tools, I make them one at a time with files, sand paper, sanding blocks, drill press and dremel tool.
Although they look nice enough "for me", they are nothing fancy, they are home-made ! but I like that hand made look, besides the sound is all that matters.
Hope this helps
