Since using a non-powered handplane with a shooting board is generally not too loud, I went out and trued the ends of the tabletop of my walnut desk that is in progress last night. Anyhow, shooting through 16" of something like 7/8" thickness requires a certain bit of oomph. Now I know why hand tool users tend to be much more fit and in shape than lazy power tool users. I think my shooting arm put on a quarter inch of muscle mass after least night!
Mark, I use my shooting board for squaring of the ends of small "stuff" like stiles, rails, aprons, small drawer parts, etc., not something as wide of 16". That must have taken a really sharp blade and a great technique, making sure you were only trying to take a smigen amount of wood at a time. You are a better man than me! I will stick with the small stuff.
