Knurled Steel Scriber

I was tired of always losing scribers and decided the kids needed to make their own.

Step 1: Tools Required

Ramset nail

100mm of bright steel 12mm in Dia

Lathe

6mm Tap

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

Like a sign I saw

BUILT NOT BOUGHT

Hi.... I was just wondering about the ramset nail? I can't find any information on it on the Ramset website.

You can find them at places like Home Depot or Lowes, etc. I was lucky enough to find mine (a small bag of them) at a garage sale.....they are not cheap at the retail level.

Here is a link to what you are looking for.

Nice.... I like knurled tools and have a metal lathe and the tools to do it as well. I just haven't tried it yet.
