Take note, this is my first instructable :P.
Step 1: Tools and What Is Needed
1, A drill and a drill bit slightly smaller than your rod your using to make this tool
2, A 3/8 inch paddle bit for longer shanked points
3, A grinder with thick metal grinding wheel and metal cut-off wheel
4, A course hand file
5, A sharp knife, anything will work
6, Sandpaper for finishing
7, A measuring tape is very useful
8, A glue of some sort, epoxy will be best, but I just used hot glue
9, The metal rod you will use to make the point, these can vary in size, an old drill bit works best, I just used a scrap metal rod off a piece of trash for this one. Just make sure it is smaller than the body can hold, and not much larger than the original tip of the sharpie.
Step 2: Optional But Recommended Tools
1, Water, as it does get hot in florida
2, Safety gear, goggles, gloves, and something to cover your face for grinding.
3, A bench vice
4, Some awesome super hero pajamas
Step 3: Take Apart the Sharpie
Use whatever way works best to take off the cap and rid the marker of the ink tube, however gripping it with a cloth in the vice and pulling while twisting worked best for me.
Step 4: Cut the Tip Off the Cap and Clear the Insides
Next you must cut the tip off the cap and clear the insides. I suggest to use your knife and press firmly till you get all the way through, then poke the felt out of the tip with your knife.
Step 5: File the Tip Down
Next you must use your hand file, and while going slow, file down the tip slightly up to your personal preference of when you want the metal tip of your "Shankie" to start.
Step 6: Cut Your Metal Rod to Size
Depending on how long you want this to be, cut on your discretion. Usually somewhere around 4 inches is good, but can be fixed later on the final few steps. "Where I cut is shown by the red mark in the first picture."
Step 7: Grind the Ends Flat and Mark Your Tip Start Point
For the most uniform tip and length, file both ends as flat as possible with the grinder. Then mark, with your sharpie body and tip along side for reference, where you want the metal tip to start, this is best done with the knife or edge of your file. I just marked from where it looks like the metal would start protruding.
Step 8: Time to Tip!
This is the hardest step in my opinion, and I will try to detail this as much as possible.
1, Affix the rod in your drill
2, With your grinder, find the most appropriate angle to meet the center of the rod from where you marked in the last step.
3, Hold both the drill and grinder firmly.
4, Start the drill and once it reaches full speed, start grinding the metal at the angle you found.
5, Remove the grinder when the tip is made, then turn off the drill
6, Wait for the tip to cool, as it will be hot.
TIP: Never stop the drill while grinding, as it will make an edge flat.
Step 9: Sand Your Tip
Using a sanding sponge or sandpaper, sand the tip to make it shiny and clean up the metal. Please try not to stab yourself however.
Step 10: Place Your "shank" in the Body and Cut Down If Needed
Place your shank inside the body of the Sharpie and depending how long you want your tip, cut that much off the backside. The first image shows how much I decided to cut off, I eyeballed the amount, and my final piece ended up being roughly 3.75".
Step 11: Drill Out the Tip to Fit the Metal Shank
Using a drill bit slightly smaller than the shank, "to make the fit tighter," drill out the tip of your sharpie all the way through to fit the metal portion.
Step 12: Glue the Metal Portion Into the Body
Using epoxy or hot glue in my case, glue the metal portion into the body of your sharpie.
Step 13: Fit the Tip Back On
This may take a great deal of pressure, but using the same method to take the tip off I placed it back on with the metal portion on the inside, it will be very tight!
Step 14: Optional: Drill Out the Cap to Fit the Metal Portion
There may be a plastic portion in the cap you need to remove to fit the metal tip, use a drill and a 3/8" paddle bit to do so.
Step 15: Optional: Color the Tip
Using another sharpie, color the tip to match the color of the body of your marker.
Step 16: Enjoy!!!
You have now made your own "Shankie!"
Have fun and go poke something (not someone please)!!!
