Not much to say about this really.

40 to 50 cm steel rod, connected by some means to a handle enclosed in a box.
I gather, 2 holes for the rod to go through and a smaller hole for the wire to feed
through.

It would be handy if I could just lay it on my lap while coiling. The box can be made
of any material you have laying around, the cosmetics of which, I am not concerned
about nor the build method but a sturdy construction would be good.

The only part that is important to me, is that the rod be specifically 6mm round rod
in steel. I normally use a high speed drill but it's noisy and I can use a manual one
at all hours.

the wire must be at 90 degrees to the rod
the spring or wire feed will have to move to give you a uniform shape
if this is a heavy duty spring you may struggle

18 Gauge Black Iron Wire, it's quite flimsy.

ok my thoughts
battery drill
close the chuck with a wooden /metal dowel/rod to pinch the rod and wire
do a few turns manually to settle the wire at the chuck end
then slowly pull the trigger on the drill and with the other hand feed the wire onto the rod supporting the rod at the same time :dunno:

I normally just attach a 6mm rod to a power drill, push the wire into the chuck,
bend the wire over the rod, hold it with my thumb and pull the trigger.

Under most circumstances, this works fine but I found an exception to this.
Black Iron Wire has a carbon layer over it, this increases the grip
of the wire, making it difficult to control with the thumb, specially with
a drill like mine that operates at a single high RPM speed.

I would either need a motor that operated at lower RPM's or just do
it manually. Either way is fine with me providing it doesnt ramp the
costs up too high.

Cordless drill is perfect for this, it's what I use when making silver jump rings.

I'm not so certain, as said before, unlike with silver,
black iron has far more grip to it, when coiling, it
laps over itself much more easily, unless the cordless
drills operate at a much lower speed by comparison
to the power drill I normally use.

I'll see if I can pick up a reasonably inexpensive cordless
drill during the week and put it to the test.

A cordless drill in low gear mode with turn very slowly indeed, plenty slow enough to keep control and still have plenty of power for this job. :thumbleft:

a cordless is typically 0-350rpm in first and 0 to say1500- 2200 in second gear

Can't help thinking you're on target with the picture in the first post. I've done the same , only difference is that I held the wire at 90* to the rod in my left hand and turned the handle in my right. I tried using a drill but found that any minimal increase in speed resulted in a similar lowering of control and more instances of the wire winding on top of itself. I also don't think you'll be able to hold it on your lap to well , much better to clamp it to a table.

Hi lads.

I bought a cheap cordless drill at a local store and sure enough, it's much
easier now to make coils with black iron wire using this tool by comparison
to the other power drill I have.

I would still use the power drill for most wires, I can spin up a 300mm coil
in 2 or 3 seconds with it but for coated wires, such as Black Iron, the
slower spinning cordless drill is absolutely the way to go.

Cheers.
Noel.
