   A chain mortiser is a beutiful thing, seemingly invaluable in fabricating doors. Is your question operation? Used one in school, like a x-y controlled chainsaw. Does similar job as router based mortising but in a big scale and fast. Consider the chain goes around a sprocket on the end of the bar so tenons need to be shaped accordingly. They come on used market for $1000 Can. often.
