Thank you sir! Yes I own two small CNC machines and have done some milling of guitar bodies - mostly simple stuff like tele's but am hoping to do a lot more as I get better with MOI. The newest CNC machine is big enough for necks so am trying to get better in that area. Thanks for the tips. Barry has left some terrific advice using booleans - trim and blend commands in particular that have helped a lot - I just need to get better at it.
