Step 10Build "Magic Pen"
The last piece of the puzzle is to construct the "magic pen".
Cut down some 3/4" dowel into comfortable pen lengths...8" or so.
Using first a small drill bit, then a larger one, bore out a hole that will accept the rare earth magnets - in my case, 3/8". Slip the rare earth magnets into the hole (polarity doesn't matter, iron filings aren't polarized themselves). The magnets should be just slightly inset of the tip of the dowel so that the softer wood bonks the glass table top, not the hard metal magnet.
Then, using some 120 & 220 grit paper sand down the dowel and paint it white to match the table.
