Easy Hand-Crank Setups for Making Coils
Article © MAIL User: Corvus

What you will need:

Some rods. You can use wood but this wears out quick so metal is better. Knitting needles (great for various sizes), scrap metal from skips (dumpsters, also good for scrap wire) and engineering companies will sell rods at small prices. Kodiak has a wide selection of rods.

Some bits of wood. Hard wood is better, avoid pine unless you are happy to replace it often.

Some screws, nails that kind of thing.

Access to a drill, saw and vice.

The easiest way to have a handle for the rod is to bend the rod at a right angle.

But you can fix the rod to a wood handle if you can get a hole through one end, then you can attach a small piece of wood and fix it with wire.

Then you will need a larger piece of wood approx 10 cm x 10 cm but it can be any size really.

Drill a hole in this (hard) wood to match the size of your rod (no jokes please!).

If you have a larger piece of wood you can drill several holes for several sizes of rod.

Now you need a workbench or vice to hold the wood.

This mandrel has a bullrace (bearing) to hold the wire close to the rod, but this is not really needed as pulling gently on the wire as you turn does the same thing.

This one has a hole in the handle to hold the wire. (Hand model is my husband!)

Push the rod in and start turning.

Using a second hole of different size in the same base wood.

Two larger mandrels, one of which was a towel rail! These can be held directly in the work bench.

Another way to hold the wire close to the rod, good for galvy or steel but not plated wires.
