Several people have asked if I bored the neck hole at a 42 degree angle too, and the answer is no. When I made the first batch of these 10 years ago I did, actually they were at a 45 degree angle. That’s pretty hard to do and made for a very tippy piece when using 3/4” stock. If you notice most of the ones people make that have an angled hole have a much bigger foot than just 3/4” stock. It also made a lot of tear-out on the back of the piece. It’s not just as easy as chucking up a forstner bit and drilling a hole. Try it sometime. It’s a nice effect to have the bottle perfectly horizontal, but it’s actually more dramatic to have it sticking up in the air a bit more. Here’s a short video I shot to send to the bride to be showing the difference.
