I was supposed to laminate the stems with unthickened then thickened expoxy. I didn't know what that meant so I asked Joe about it. Unthickened expoxy is the 2:1 mixure without the hardening powder. He said that I didnt even need to use the expoxy since the stems should not see water once glassed. So i went with wood glue.
Here is the internal stem alone, mounted on the form with screws. You can't see it very well, but this piece of wood is actually thin strips of cedar glued together to make a thicker strip of wood, which needed to be bent to the form.
Next I had to shape the internal stem so the end of the strips would lay flat. I didn't really have any idea exactly what that should look like, so Joe had to send me some pictures. It ends up looking kinda like a triange with the top ridge about 1/8th inch.

Here are some pictures of my partially shaped internal stem.
You can see how the unshaped stem is rectangular and the shaped part is angled. At first i tried using a block plane to shape it, but that didn't really take off enough wood. Then I started using a rasp (4 in 1 rasp), which worked much faster. I followed that with some 60 grit sandpaper covering the rasp, then 80 grit for the final shaping. I'm certain there is a faster way, but that's what I did with the tools I had.
(addendum: After working on the internal stem along the way, I ended up mostly using a sturdy box cutter to do the initial shaping then using sand paper to do the finishing touches.)
