Knurling for Lathe

thingiverse

The reference part I created was more for guidance. If feasible, utilize metal, steel, or aluminum. The hole should be threaded to M6. Two rods with pin lock washers for the knurl wheel were made in the lathe, but you can use two 3/16 x 25mm screws. (The knurl wheel I had here was a 16x8mm with 5.7mm hole. Unfortunately, an M6 bolt does not fit in the hole.) Glue the M5 bar on the knob with cyanoacrylate. You will also need: 2 Screws M6 x 25mm, 2 M6 nuts, 1 Screw M6 x 20mm, 1 Threaded bar M5 x 80mm, 1 Spring pressure 6 to 8mm internal diameter and 50mm length. Two washers (M5 or M6 depending on spring diameter), two screws 3/16 x 25mm. Two nuts 3/16 (Better if nyloc). Best print with: 0.2 Layer, 80% Infill. Use support only in Rod_1.stl. # Update Added Arm-threaded.stl to make thread in one of the holes and to dispense the M6 and 5/16 nuts. It is possible to create threads without using tap thread. Simply grind the tip of a screw into an emery or even a file. Lightly heating the tip of this new tool can help when making the thread.
