I'm sure you know the phrase: "Cuts like butter" - well, this "Cuts like wax" ie. very easily.

Michael, sounds good. Not sure what you're implying with the hot wax though mate, remember this is a family-friendly forum

Good glue is evil

just had to try this

i just had to try this idea, raced out and grabbed some candles
here is a pic , it turns ok, but you have to watch the flaws in the wax, will wind up a coil tonight, its so cute i do not want to dip it in the hot water.

well i got to dipping my wick in the hot water yesterday, and there is a couple of things i discovered.
1. use hot water
2. trim the wax first, keep what you put in the water to minimum
3. use a big container, as the wax floats and when you take the coil out of the water i was ending up with a thin waxy film on it
4. this process makes a very neat and square coil

You need to clean that lathe! Man that thing is a mess, And can damage the way's from all that grit and oils will make a good lapping compound.
Just my2cents.
But love the project

Looks like the dirt is on the bench not the ways, it's only a wee one

hi guys i know what you mean about the grit but this lathe is well past its use by date, the bed has worn to an S shape, but it still makes small projects if i use some tricks, and hey if i clean the bench i will never find anything !

Hi All,

I have made a few coils using the method described, but I am having a problem. I am using CA to hold the coil together, and when I let the wax melt (with hot water) there is always a residue of wax on the outside of the coil that seems to be bonded with the CA. It is of course, almost impossible to scrape off without damaging the this wire. Does anyone have any suggestion as to what I may be doing wrong?

I made a batch of these "bobbins" last friday at school. Managed to get down to a 2.5 (ish) inner dia without any metal core.

I will try out this method during the week with some 0.02mm wire from Fill.

Try switching to one hour epoxy, the wax can be cleaned off with rubber cement thinner, which is similar to film cleaner. Tri-chlor-ethane I believe is the chemical name for the solvent.

Yesterday I remember this method to make the coins, because I did it very "artesanal"..... with balsa containers, paper rolls with maskin tape, and grease!!!!!! this method looks great, and I not expent many time!!!!

Thanks Mike

wax on coil

when i made mine i used clear nail polish , not as quick as CA but only takes a few minutes to dry,and does not stick the coil to the wax,
in my post above, i made mention of wax on the coil after melting in hot water, the trick seems to be to trim as much wax off first, and use a LARGE pot of water and give the coil big swirls to wash the wax off, this makes a nice coil.

Thanks Michael for this great idea. Now I will try to make custom coils as well...

Crayons might be cheaper than candles, depending on whether you can use
the normal sized crayons. If you've got kids, you've probably got all sorts
of broken crayons around just waiting to be made into coil forms...

If you have the ability to machine a bobbin out of metal or soft plastic or you could just scratch build one
You can make a Rtv mold out of that bobbin and just poor hot wax into itů
Mini Production line with out all the time spent trying to machine matching bobbins

If you need a high quality wax is needed I suggest machine wax most of the time its comes in blue
