Vince, I made one a few years ago. I was out turkey hunting, and it was the last day of the season. I had two jakes come in to range and I gave them the pass. Hoping there would be two more nice gobblers out there for next year. I had thought of making a wing bone call, but had always heard you wanted the wing from a hen. Here in Florida you are not allowed to shot hens. Anyways, I'm on my way home, and hen runs out in front of the car in front of me and gets wacked. I pulled over and load the bird up into my truck. Here's where it starts. Once you have the bones clean of meat. Carefully cut the ends of the wing bones off(the knuckle). Then I used a piece of wire to clean out the marrow. The big bone( the end of the trumpet) Has a lot of boney veins running through it, that you need to remove. I used a screw driver for that. After it was all clean I boiled the bones again to clean them up the rest of the way. The bones fit inside one another, and you want to keep the joints as tight as possible. So I used sand paper on the bone that was going inside of the other larger bone. Going easy until they fit together. Once I had it all put together I put a little glue on the joints. I 've never used it in the turkey woods, but maybe this year with my decoy. If you have any questions about the call let me know. Jeff
