    Lightbulb Clamp Type Knurling Tool

    Made this Clamp Type Knurling Tool based on a smaller comercial item I already have. This one can be used on bigger diameters [bit over 2"], mount centered on tool post and is more robust. Screws can be tightened to remove side slope.


    Test run showing welded support.


    All parts were made in a lathe. Just Facing with a 4 jaw chuck.


    3/4" by 1/4" flat bar was used for this four pieces. Two of them have central hole counterbored. In this hole a small spacer [same wheel thickness] in mounted for rigidity.


    Used 1/2" square bar to this piece. The area with holes need to have the thickness reduced to same wheel thickness.


    You will need also:

    * a threaded bar, M6 or 1/4".
    * Two Ø1/2" bar 20mm long.
    * A special knurled nut you can made.
    * Two knurl wheels.
    * Two 1045 pins for knurl wheels. After turning them, heat with a torch and quench in water. Test hardness with a file. Unfortunatelly didn't have any photos of them. Just make the diameter of one side slighty bigger so they mount pressed on side plates. Or use a car poppet valve stem, or a hardened bolt.

    Since I have too much knurls, made a comparator display to better (visually) choose the right one.

    Very nice compare several different. Gives a great view of better and worse. Very nice cutting the flat to identify.
