Aka, “Son of Junior”
The intention is to build much bigger CNC router than we currently have.
Effective table area of approximately 40“ x 40” (probably a little less due to spindle width, etc.), Z-axis travel of about 4-5“?
Current Status: Some parts have been built, courtesy of Steve Gray. Parts should arrive at the space at the end of December 2018. Assembly to occur beginning in early 2019.
X-axis: 1/2” supported rails with cast blocks. Leadscrew motion.
Y-axis: 1/2“ supported rails with cast blocks. Twin Leadscrew motion.
Z-axis: 1/2” supported rails with cast blocks. Leadscrew motion.
Spindle: Makita or Grizzly laminate trimmer router. (measure diameter of Grizzly router to see if it will fit)
Frame: Welded square steel tubing? Wooden torsion box? Aluminum extrusions are probably prohibitively expensive.
Dust collection: will be tied into our dust collection system.
