homemade coil windings?

[oldnlazy]

Anyone experiment w makin their own custom coils for the x-terra & in general? Anyone have how-to info to share here for us folks that can't afford these new coils @ 300. Bucks a shot..

You can find a LOT of used coils on ebay at half that or less. There are several videos on Youtube about making coils.

Whole idea is not to purchase. I am a hobbyist looking into. Making my own custom windings and encapsulation to improve on the current $300 aftermarket large coils for the minelan exterra. Thx however..

What you are proposing is a way to spend huge amounts of time playing around with stuff that will produce many failures before you achieve success (if you do at all). And the right materials are gonna cost you. And if you don't know what the heck you're doing, you'll never get a usable searchcoil out of the project no matter how many times you try.

As a way to just DIY and save a few bucks, it's a really bad idea. Real manufacturers have already gone through the grief of figuring out how to make a searchcoil that works. Buy factory new; or, used, but only if you trust the seller.

Go to geotech forums, there is a wealth of info about making coils. However I have made my own PI coils for the Whites TDI. Its a mono coil and the easiest to make. It cost almost as much to make one as it does to buy a factory coil. The reason is that the components are expensive in single quantities. You will need a good inductance meter $100+ (cheap won't do). A good O-scope is almost a must for a high quality coil. You need to build a coil form. Getting the winding just the right size to fit the finished coil into the housing is difficult. Then if my memory serves me, the exterra has a micro-controller built in to the coil. Starting to get the picture?

Bottom line, its much cheaper to buy a very good aftermarket coil than to build your own. However, the learning experience is priceless.

Building mono coils for PI's are the easiest. DD coils and concentric for non metered machines takes more skill.
Won't waste my time or money building a coil for a digital metered machine any more. Tried building one for the Tek Omega. Actually worked somewhat when nulling the DD coil windings but, the ID meter would no longer work properly, nor the mult-tones. The coil windings were put in the spare parts box............

Not very cheap on amazon. Mostly dealers selling new coils i.e. Kellyco sells there.

Chech out your local mining shop they might have some or be able to point you in a direction to find one.
