Ok I've wound a few coils now and it is getting easier and easier as I gain the ability. I have ordered some different gauges of magnet wire just experimenting. The last one I wound will give a decent spark at 4 Volts a weaker spark at 3 volts. Runs my Atkinson engine really good and makes it a good starter just barely flip it over top dead and shes off and running. The one I just finished is about the size of a c size battery. Was going to use the shell of a c size battery but changed my mind and am going to stay away from a metal casing and using pcv instead. I'm thinking of using a couple of them on my Mini Hog engine.

Doc, I am very interested in your coil-making. Do you have any plans or resources that you could point me to to find out more about how to do this?

It is in the Bob Shores book Ignition Coils And Magnetos In Miniature
It is a very well written and interesting book. I do recommend it to anyone that desires more knowledge on coils and ignition systems.

Enjoyed the video - great job on the coil! Have you made any videos of the actual making of a coil? I'm about 120 pages into Bob Shore's book, and for the most part it all makes sense ... but it would be great to see how it actually works in practice.

Also, where did you source the magnet wire? And did you cut up a transformer for the core laminations?

The wire I got off Ebay it comes from Tempco.

The lamination's came from an old transformer

After making a couple coils I found that I only need 2 drops of wax on the starting end of the wax paper and to not use to much wax. It has gotten easier to wind with every one that I wind I have 5 wound up now.

Hat off to you for taking the time to produce the videos.
Terrific achievement.

Only comment is there are times when you are doing things outside the range of the camera but in most instances the commentary covers what you are up to.
One again, great stuff.

I wound 2 coils this morning thats 24,000 wraps of 44 gauge wire. I think that will be it for awhile. I'll finish up these 2 and put the stuff away again. The wax is warming up right now that takes about an hour or so to get to temp. I'm finding it pretty easy now after doing (I think) 9 of them now. Good luck and happy winding lol.

If your pulling vacuum on a glass container, you may want to consider wrapping a grid of electrical tape on it as a precaution against implosion. You can still leave some spots open to see what is going on...only takes a scratch to initiate a failure and ruin your day.

I'm using a mall slow cooker with a thick plexi glass top that I installed a vacuum gauge and a check valve that I attach a hand vacuum pump to. I let the crock pot get the wax to 86 degrees c and then pull a good vacuum on it. So far it has worked out great. I can see the coils and judge when to release vacuum and then re pull a vacuum again I do that several times to remove the air and moister from the coil.

Thanks for the videos - I know it takes time to make them. I have a home made stepper driven coil/transformer winder after watching your videos I may well have a go at making my own coils.

Lid is plexiglass, a form of hard impact perspex, not glass as such.

When we do casting. it tends to be much the same.
