Alma, The mandrel goes into the check, the handle does go into a vise
with the turning device easily accessible, and the wire to be coiled
reasonably pulled straight.
I use a piece of chamois to hold the wire firmly in my right hand and
guide the wire to a close coil, turning the drill with my left hand. I
tend to use either hand easily so it is not a problem. Having the
ability to control the speed of the drill avoids and overlapping of
To facilitate the ease of removing the coil, I have sprayed the
mandrel with Pam or similar.
For a bit more automated coiling, I use a cordless screwdriver, which
also turns at a far more manageable speed.
If you get the urge to do chains, the links can be made the same way
preferably using a wood dowel, after completing the coiling, tape
along the long side, and use a spring steel fine cutting blade in the
Dremel or Foredom, exercising extreme caution.
Enjoy and have fun,
