Hi Kris,

I also have used bobbins in my PSK to store cordage (Spiderline/thread).

I stole the bobbins from my wife's sewing drawer late at night and to date she has not missed them (shhh). The bobbins were fairly thick clear plastic and I filed down the top surface to make it thinner. If you needed to reduce the diameter of the bobbin then lock a tapered short piece of wooden dowel in a variable speed drill, push the bobbin well onto the dowel and hold a file to the spinning outside edge to reduce the size. Be careful not to spin it too fast as the bobbin will fly off the dowel spindle or the dowel will break.

There are metal bobbins also (I actually bought these at Wal-mart) but I have not tried to modify them yet.

I feel your pain concerning your wife thinking all your preparedness equipment is "junk"; don't worry brother, "remember were all in this together" (Steve Smith a.k.a. Red Green).

Good Luck,

Mike
