Aka, “Son of Junior”
The intention is to build a CNC router capable of manufacturing a guitar body.
Effective table area of approximately 24“x48”, though 48“x48” is under consideration.
Current Status: Still largely in planning, but we're playing with some design options based around things we already have or can make/acquire easily.
X-axis: Current thought is to use the “Sears Axis”, or possibly cut-down supported rails. or the supported rails with no cutdown (48×48 version)
Y-axis: Current thought is to use the 1/2“ supported rails, along with cast blocks. Not sure of the drive mechanism yet.
Z-axis: possibly using a leadscrew from the optical mechanism we acquired with the “Sears Axis”, and some of the linear rails on hand.
Electronics: still unknown. grbl is a possibility, though bigger motor drivers would probably be needed.
