MPCNC Z-AXIS DRILL JIG - C, F, & J sizes
thingiverse
I have updated (3/24/2019) this thing to include jigs for J, F, and C size MPCNC tubing. Also I provided jigs for both 4mm and 6-32 screws. All size variations are included in this one download. I am building a MPCNC J:https://www.thingiverse.com/thing:1671517 It is a beautiful design; I tip my hat to Allted. But I got stuck when trying to drill the holes in the z-axis pipes. This Jig helps drill those holes. This jig helps drill the two holes in each Z axis tube at the correct spacing, using the skate bearings and fasteners used to build the MPCNC. The only part you would need is a 5/16" center drill that you can buy in a package of 5 at Harbor Freight, item 60381. Or an 8mm drill may also work, but I don't have one of those to test. It should fit within the bearing.
