Step 1: Tools Required
100mm of bright steel 12mm in Dia
Step 2: Procedure
Cut the 12mm bright steel to 100mm long
Center drill and face both ends
Using a 5mm drill, drill in 30 mm from one end
Using a 6x1mm tap, tap down 25mm - I hold the work in the chuck and start the tap by holding it in the tailstock
Fit the ramset nail
Fit the scriber in the chuck and cut a 6degree taper - I like to fit the nail and leave @1mm clearance
Step 3: Knurling
Hold the scriber by the nail in the chuck and support the other end with a live center
Set up the knurling tool and cut the knurl using the auto feed
Clean up and enjoy
