Coil winding

I want to wind some small coils for a project and came across this.

**LINK**

I’m not sure how well it will work with some of the wire I’ve got but given the low cost I thought it was worth a try. If the 2.0 works I may get the other two.

Just sharing as I thought it was a neat idea.

The video is a demonstration of a tool for winding vaping coils for kanthal wire for those e-cigarette things. Seems like it could be re-purposed for winding coil-springs but it might not be man enough to coil spring wire.

A variation on a theme.....piano wire bending comes to mind

Yes that’s right vaping coils, the clue is in the posters name VapeSource.

I can’t imagine it would be man enough for wire springs unless is very fine wire. Interesting little jig though for softer wires.

I was surprised how soft the wire is for making vape coils, they stay close to the size of the former. Spring wire is going to need some experiment to get the desired finished size or calculation if you have the data. It certainly provides some food for thought, should not take too long to knock up a quick and dirty version in the workshop.

IF ONLY I'd known about that method when I was winding my balance spring(s).

This was the best I could manage using guitar strings. All previous attempts ended with intertwined loops whenever I released the tension.

For reference ...

Wire diameter = 0.008" (0.2mm).

Spring diameter = 0.375" (9.5mm)

Turns required = 9

BTW - For those interested, the clock has been running since late 2010. You can track my article about building John Stevens clock using the notes at the bottom of my profile.

I think that is the difference between winding a coil and winding a spring.

They are a great idea could do with one of them as it would be great for coiling wire for my pyrography machine

If you are going to wind an electrical coil (to make an electromagnet, etc) then spring-back should not be a problem. First, the copper wire is not supplied hard-drawn but fairly soft, and second, it is helpful to varnish the windings and possibly tape them too, before removing tension from the coil.

If you are winding a resistance or heating coil, there is still no need to use hard-drawn wire, but of course you will not be producing a tight coil as air must circulate.

This is what I’m hoping Derek!

The winder arrived today and I’ve just tried it out. It works very well. I did manage to make a couple of coils in 23swg NiChrome wire for my Pyrography machine the other day by winding it by hand around a drill bit but failed miserably when I tried thicker 20swg wire. The Kuro winder coped with the 20swg very well. The smallest Kuro CW-20 (2mm mandrel) seems about the right size but I’m going to order the CW25 anyway just to try.

Using the lathe you already have would be cheaper.... yes?

Does your wife know how to use your Lathe?

Found this a very interesting subject, many moons ago I made small point motors for my nephew,s model railway. They were just simple coils of wire wound on to pieces of tube with a piston free running through the tube connected to the track to be changed. Two such coils were wound on the same tube so the piston could be moved either way.

The best part was that the coils were wound using a simple hand drill,not an electric drill,the old turn-the-handle -type.Worked out the ratio of the handle /spindle in order to get the same number of turns on each coil. Worked out great. How did I know how many turns to put on ? I did,nt jus gave a guess.
