I promised to do this a while back, but finally got a stretch of time to do a complete call. Here is how I make my reelfoot style duck calls... many thanks to Fred Roe for his tutorial and guidance last year. This particular one includes a brass to wood lamination, but the same basic steps apply when making an all wood call. Here are my ingredients: The first step is to drill the barrel - my barrels are between 4 and 4.5" long, and I use a 3/4" hole all the way through. In this case, since I was doing a glue up, I drilled the barrel about 2" deep with a 24mm bit and then the rest of the way through with a 3/4" bit. The 24mm is a mortise for the tenon on the brass I'll be gluing. I'll use this measurement to make sure my brass tenon is right.
