The exhaust half of a grunt is just a tube with a 5/8" hole bored through it, so I will go through it pretty quickly. I mount the 4" blank on the expanding mandrel and round the blank off and taper it down until the top end is just slightly smaller than the bottom of the barrel.
Now it's just a matter of flairing the inside of the exhaust and round off any decoration that you want to put on the end of the tube.
The next step is to make a part to hold the reed and couple the two halves of the call. I like to use a piece of 5/8" delrin rod. Place an 1-1/2" piece of rod in the collet chuck and drill it out with a 1/2" bit.
This is what it will look like when finished.
After the call has been sanded and finished, epoxy the delrin rod about 3/4" into the exhaust and insert the reed. Be sure and set the reed so it stops about 1/8" short of the tip of the tone board.
Here's my call with a quick wipe of BLO and dry fitted. I will post a picture of the completed call in a few days.
Hope this helps you get started. Please feel free to ask any questions.

On an all wood grunt. Plus I don't have to measure the tenon. Take a little off take a little more off. It's 5/8". Drill a hole 5/8" and there you have the perfect fit
