Lathe Gouge Grinding Jig

This is a grinding jig I made to sharpen my gouges, inspired by the Oneway Vari-Grind jig. The angle of the foot to the tool is adjustable from 15-90 degrees to fit your tools and grinder, and it fits gouges up to 20mm wide. If needed, I can update with larger toolholders. This model requires two thumbscrews in ¼"-20 and prints in four separate parts with no supports required. 

Printing tips- 

• Both the 3MF and STL downloads are single files containing all the models - make sure to import “as objects” and not “as parts” if your slicer requires you to specify, and then auto-arrange. 
• The tool holder at the top of the jig should be printed upside-down so that the opening looks like a teardrop. This ensures good fitment in the slot where the dial attaches. All other parts can be auto-oriented
• My OrcaSlicer save file is already laid out and painted with colored indicators, as shown in the cover photo

Additional parts: 

• 1x ¼"-20x 1" thumbscrew
• 1x ¼"-20x ½" thumbscrew (or just buy two in 1" and cut one down to size)

Assembly is straightforward:

1. Glue the dial into the slot in the tool holder as shown in the photo
2. Thread a ¼"-20 thumbscrew through the hole on the top of the toolholder. This will be used to hold your tool in place.
3. Press the joint at the top of the leg into the circular hole in the dial
4. Align the printed flange nut with the leg on the opposite side of the dial, such that the square section can slide along the slot in the dial
5. Thread a screw through the hold in the leg and into the square flange nut. Snug this screw down to hold the leg in place, and loosen it to adjust the angle.
