So I used a sardine can  key  last time and I liked the ability to  tie off the small roll. SO  I had that in mind, I looked for something small but large enough  for a  550 cord  to  get through easily, also wanted something cheap and easy to replace.  Bingo, a standard ink pen. I also used other styles they all work fine, 550 cord can pass though them easily, and they weigh basically nothing. I think I'll roll some duct tape this way in the future too.

So you put the pen in like a drill. Keep the writing end out so you can hold  it and let the pen shaft pivot around it as you roll. I used a screw driver  handle to  hold the big (ok normal size) tape roll

I was  able to easily get  4 spools on one pen. I have no idea  how long these rolls are, but this is for for  small jobs, it should be plenty. The shaft  of the penis  in the drill so if you  hold the writing  end the shaft will just pivot  around it smoothly

Once rolled, I cut each new mini roll off the pen (remove the ink part first) Actually I used the drill to  help cut, but after a few times this way I   used a decent pair  of scissors which just cut  right through the pen easily, that's much faster

So  one pen, a drill, some tape and ten minutes later you can have mini electric tape too.

That was too easy and clever so I decided I should have other colors. This is wen the elasticity of electric  tape came  into  play. If  you let the tape stretch as  it comes off the original roll it will cause weird stuff on the pen (mini  roll). As the tape begins to constrict  after  being stretched it warps the roll  a  lot. This was a horrible  failure with the red tape.  You'll need  to go  much slower or  just buy heavier tape so it doesn't stretch as it  comes  off the roll so easily.

Being one to use all the parts of my kill, I made this handy mini-Tactical pen out of the pen parts left  over after making mini-rolls  of tape
