wall thickness of stopper (help)

[michi-gander]

I'm a little stumped, when I drill a 1/2" hole in my stopper, turn down to fit in 3/4" barrel with O ring grooves does that safely leave enough material ? And also if U use 5/8" guts do U open up the stopper end of barrel to 7/8" or use a different method. A photo of goose call opened up would be great. thank-u so much for any help!!

It all depends on the materials you are using on your exhaust pieces, to determine if the tennon thickness will be ok.  If you are using acrylic, then most calls have a 7/8" tennon with a 5/8" bore.  If you are using wood, then there are a couple of tricks to getting that thin tennon to survive.  Jester has a technique posted on here to cut a groove in the tennon, wrap thread in it, and then fill in the area with glue.  Other folks use a gutsert on their wood exhausts.  

On the goose calls that I make, they take a 5/8" gut and I drill the stopper 5/8" all the way through.  The part of the stopper that fits inside the barrel is a 7/8" tennon.

Here is a good read with some pictures of goose calls that aren't assembled.
