RestorationAD, when you say you're going mechanical do you mean like a Duplicarver type set-up? I really think if you're already building guitars, the leap to CNC is not a big one. Your signiture mentions 'IT' in it, if you're computer savvy then you're half way there already.
If cost is a factor, consider the TableTop version Im building (see above post with YouTube link) as I will probably have under $200 invested in that CNC when its done. $150 of which is for the 3 motors, driver board and breakout board. the other $50 is for the piece of MDF, hardware store stuff like pipe, aluminum angle, skate bearings, various bolts nuts and screws. The Dremel I had already
Other costs for me that may be helpful to others who want to know what CNC will cost:
I will purchase a CAD program such as Vectric's Cut2D $149
I will also purchase a CAM program: Mach 3 $175
The above programs come at a cost, Realize that there are similar FREEWARE programs that will also get the job done.
Thanks,
Vinny
