Wandering,
Having run mine about a month ago, (I was making a replacement piece for my 73 GMC) I can tell you that it is a molding cutter. It will either put fancy edges on a single board or manufacture molding strips. It is at home in either a table saw (with a cut out table plate - what I use most) or in my (also Dewalt antique radial arm saw. While the radial has the advantage of control of the working piece, feeding the stock to it is inherently dangerous.
Mine is a three cutter version and so has a smoother cut and less vibration, but it is just a dangerous.
I hope it serves you well.
