most cnc machines require you to be able to write the program in g code which will take considerable time and the cnc is not as fast as a duplicator a duplicator can cut a crankbait body in about 60 - 90 seconds just depending on how smooth you want the body the slower it cuts the smoother the body but like bruce said there is alot of thought that goes into the design and into building the final product and be prepared to fork out some major bucks for some precise machine work it will take alot of machine work to keep things precise and in alignment to keep from cutting one end of the body smaller or larger than the original what this meens is if its out of alignment it will cut the front larger or smaller than the original or the tail larger or smaller i know this from experience the cnc machine will however come in handy to cut out flat bodies but imo they are to slow to cut out round bodies thats where a duplicator will be your best bet
