most of the coil cutters are made to do 3 inches at a time. my preference is to use the flex shaft and a rod the size that I want to make coils 1 foot long. then with the saw and an 8/0 or 6/0 blade cut through them.once you get the hang of it it only takes 10-20 min to cut a coil. if you would like a longer description then ask me.
Robert Earl: You are quite correct in stating that most of the jump
ring coil cutters are made to cut a 3" long coil. In addition to the
standard (3") Jump Ringer, we produce a model for the person who
needs to make large volumes of links in a short time. It’s called
"Long Jump Ringer" and contains a Long Coil Holder with 4 different
size “V” grooves for securely holding 1.5 mm to 1/2" (13mm) I.D.
coils up to 15" (375mm) long.Drill Stand which mounts to a table and
securely holds your portable electric drill in a horizontal
position. In use the drill’s trigger switch is locked in the “On"
position and its wire is plugged into your Foredom foot control.
This allows for infinite speed control while leaving two free hands
to control the wire. It also comes with the Jump Ringer Saw
Guard/Guide, blade and blade arbor. With this tool a 15” long coil
can be wound and cut into perfect jump rings in three minutes.
Usable wire diameters range from 30 to 12 gauge. Long Jump Ringer is
available from your favorite jewelry tool distributor. Foredom vs.
Dreml We and other manufacturers of quality tools that require a
source of motive power have all designed our tools around the
Foredom Flexshaft machines with their #30 headpiece. While Dremls
produce the required speed, they lack the necessary torque (twisting
power) to do this work efficiently. Because of this, if they can do
the work, they are constantly working at or near capacity and will
soon burn out. If it would fit (it doesn’t) replacements would soon
overtake the initial cost saving. Over the long term, cheap is
