Thanks everyone. I really enjoyed this project and I can certainly see how this will become addicting. The rear plug and spout plug are made of maple. Not really knowing what finish to use, I just used tung oil. The only thing I would change, is utilizing a larger horn. But hey, there is always the next one.
I know there are many different size, and shaped horns. What size would you consider being the most common, and how much powder would that hold?
Anyhow, thanks again. and Merry Christmas.
