Saw your finished Horn and it came out well. Looks like you found some old growth pine for the base. I’m always keeping my eyes open for pieces of old growth pine, poplar, cherry, walnut, etc that I can make domed or turned bases from. I have hit the mother load a couple times at estate sales of two guys that were older woodworkers, who saved everything. I bought some smaller scrap old growth pieces of thicker wood that nobody else really wanted for a song at both sales. One source to be aware of.
I guess I’m resembling one of those old wood worker more myself every day now. And I have the old scrap wood odds and ends to prove it! 😀
