After the discusion over tube calls I decided to take a bunch of pics and try to put one together. I do mine a little different so here goes. If there is no need for it any more that is OK to.
This first step could be eliminated if you were to just chuck the square blank up and bore it that way.
1. I start with a 3 1/4 ish long blank and turn it round between centers.
2. Next I chuck it in my knuckle buster chuck and make the first bore. I step drill mine so they get drilled in two steps. The first is with a forstner bit about 3/4 deep on the mouth piece end.
3. Next I finish boring it out with a jobber bit.
4. Next I sand the inside of the bore.
5. I flare the bell on mine so next I drill the bell end with my step drill. I do this on my expanding mandrel. Be carefull to make sure there is enough distance between the end of the step drill and the mandrel as you drill in. Don't ask why I caution this.
6. Bring up the tail stock and turn to your desired shape.
7. Sand it out and put your finish on it. I CA mine.
8. Here is a shot of the mouth piece end before the lip stop end goes in.
9. I don't have a pic of the next step but since this one has an antler lip stop I rough cut it and shaped it with the belt sander. If I am using the same wood as the tube I start with a longer blank and part off a 1" slug from the end before I bore it. I make my lip stops so they are about 1/8" thick and they cover 1/3-1/2 of the opening.
10. Once the lip stop is fit I hold it in place and put a drop of CA on each corner and hold it until it sets up then I glue it the rest of the way around.
11. Once the glue dries I sand the lip stop down flat up through 600 grit. Then I put a couple of coats of CA on with a Q-tip.
12. You are ready to put the reed on and tune it up. Be carefull that it doesn't get to tight and keep the gap in kind of a crescent shape.
If you don't know how to use a tube this is where the learning curve begins. Here is a link to a video that I found very helpful for mouth placement and technique.
Good Luck
