Now that y'all have helped me figure out how to turn adirondack spruce, I'd like to move on to the finishing phase and ask for your advice on finishing. The pen is a combination of adirondack spruce and cocobolo. I'm going to make the pen body out of cocobolo since that part will see more handling since that's where it will be gripped whenever it's being used to write. I'll make the top part of the spruce. That should help make it see less wear, but I'd still like to make a durable finish. Is there any merit in starting with thin CA so it soaks in to the spruce and then moving up to medium for the finish coats? If I do that, will it matter if I use different brands of CA?
