Hello,i have made a home made big buck call.Wich was realy a piece of vacume cleaner cut to 7 inches.After two solid years of practice i have come up with a grunt that certainly works well,and sounds the same as a Fallow Deer.



But........After trauling aroung i have realised that the grunt calls have a little daiphram in them that make the grunt.Can anyone suggest what to use as a diaphram and where i should be placing it in the call.

I can't seem to find an internal diagram anywhere.Cheers!
