A few years ago I used to make enclosed reed, open reed, howlers, fawn, crow, squirrel, and deer grunt calls. I found myself spread way to thin, so I decided to go strictly open reed distress calls now. There were too many types of calls to make, and not enough time to make them. LOL!
I focus on open reeders now, using my Bunny Bomb tone boards, and the occasional enclosed reeder. When I used my last howler board, I quit casting them. No more squeakers after I used my last squeaker reed set.
I cast the Bunny Bomb tone board blanks from a silicone mold that I made myself. The come out of the mold just a hunk of resin, about 75% complete. I finish each board, one at a time, as I make my open reed calls. Each board gets the air channel milled in, the back pressure relief bored, the final arch made on the tone board, and the reed trimmed and tuned.
Each Bunny Bomb board is finished and tuned, one at a time.
