What size spline wrench for spindle rf31? | The HobbyMachinist
Make your own. I made this one for a Grizzly G0755 from 3/8" 6061. View attachment 246271. Thanks for the drawing. With all that it is a nice easy CNC project to draw up and make. Or just be able to bore the hole manually and cut the slots manually. The Rong Fu 31 has a 28mm spline spindle.
