Thanks for sharing, Joel. I've just been plugging numbers into FSWizard for cutting force estimates, mahogany material. It sounds like you're getting satisfactory results at around 20 lbf cutting force, which is pretty decent. I'm sure a big shopbot is more than twice as stiff so perhaps 40 lbs isn't really near the limit on those machines, but rather a good starting point.
