Simple turns counter for coil making

I often loose count while winding a coil.

Can anybody recommend a cheap, simple turn counter?

Tinkerer

I don't know if you are still interested in a very simple answer, but I bought some really cheap electronic counters on ebay, added two thin wires so that I could add an external micro-switch.
My first attempt did not count correctly because the switch needs about a 50:50 on to off time to count exactly right.
So I placed the D shape on a bearing so that the half round of the shape holds the micro-switch closed for about 50% of the time/turn. Works great.
See the picture for the ones I bought! I got two for about $5 if I remember correctly. I placed the wiring so that the button still works.....there was even a spare battery included for each one!
If you want any further infos just ask.

If you dont want to use glue,use an old oven and try bake the coil.
Start low with a test piece let say at 50* and see how long it takes to stick.
Dont do it to high oterwise the lacker of the wire wil desolve it only have to stick
so the coil wil be solid and no more sticky fingers ;-)

Btw winding by hand can be done but slow and à little tighter than a machine winder.

Just my 2 cents

That's it! Garrett, not Tesoro.

Hi All,
The link to the Garrett how-to video does not work anymore. I found another link, http://www.youtube.com/watch?v=hUDLXEiIsxI
I think the language is czech or polish, but you get the idea from watching the video...

Well the baking goes back donkeys years ago the windng was lumed with wax string as i do then they used to soak wool bandage in varnish and wraped round the coil, after that the hole thing was put into a vat of varnish for 48hrs, then they were baked for a time in a oven, the main reason for this was to stop chatter within the laminations.

My dads well in his 80s now, and has said on more than one occasion why dont we make are detector coils like that, ive promised him the next time ill try it out.
So good on you Tepro, just takes a bit imagination and lisen to them who has experience from many moons ago.
