Dear Elmer,

I'm wondering if snyone has successfully employed a "turn counter" for counting turns in a coil as you are making the coil.

I know that there are electronic devices that will tell you how many turns are in an existing coil, but that is not at all what I'm interested in.

I'm wanting to build a mechanical device that I can crank and load wire to a form that I have insrted, and as I crank I don't have to count.

I need a device that will count the turns of a coil as I make the coil. I envision something as simple as the little clicker that an umpire uses, where as the center shaft of my crank turns, it trips the clicker.

Any advice on that?

Thanks.

Check out the neat coil winder (with counter) this guy built.  Scroll down the page to find it.

While you are there check out all the other home projects this guy builds, really pretty stuff.

Are you interested specifically in the number of turns on a form only?

Are you interested, as well, in the length of the wire coiled on the form?

Turns counting would be good to know indeed.

If you wanted to know how many feet of wire has come off the "spool" while you're winding the coil... I am wondering what it would take to get one of those "wire feet counter and roller unit" things like they use at "Home Depot" or "Lowe's" when you purchase wire by the foot...  That may be something worth looking in to.

Now I am curious because of the VLF question I just read before I read this one...

Are you experimenting with a VLF system?

Are you building Tesla coils?

Perhaps, Both?
