You are right, sholcombe; I agree that it is safer if the router or Dremel are fixed below the table. However, if all safety requirements are met, the "overarm" devices would have the possible advantage that you can see firsthand how the work is developing.
Indeed, it is possible to compare the CNC router with overarm devices, with the huge difference that the control is automated.
Thanks for the offer to cut patterns in your shop, but I guess the great distance should make unaffordable the cost of shipping.
