Coil wrapping made easy

[Tibuck19]

Personally I like this idea a lot for coil wrapping especially flat coils Share your thoughts.

Outstanding!

A lot of blablabla

I thought it was a good video, with some out of the box thinking.

That's pretty slick, I think this guy did a fantastic job. Once upon a time I designed a walk-thru detector with a 7-foot long TX coil. We thought about a similar approach to wind it, using a big (8-foot) CNC router with the router replaced by a wire feeder. In the end, the coil only had 8 turns, so I built a plywood table with corner pegs and wound it by hand. And in the very end, the whole effort got canned.

Carl, can you give opinion on this type of flat spiral coil in DD configuration for pulse machine. With a rig like the one shown in video, it would be easy to make.

[Carl-NC]

No idea, I've never made a flat-spiral DD.

like this ?

[dbanner]

Yes, exactly like that. You could make this coil no problem if you had device shown in video.
This would be a superb coil for pulse machine.

Seems that Detechs makes a 15 inch flat spiral Double D coil for the Minelab GPX,GP and SD series detectors. If I am not mistaken, these are PI detectors, so obviously the flat spiral is a superb type of coil for pulse machine.
The price of the 15 inch Detect is around 400 US dollars.
You could easily make such a coil for very little expense if you had the rig shown in the video.

[dbanner]

One of the problems I foresee is how to accurately calculate the inductance of a qausi D shaped flat coil. You would need to experiment a bit.

Now that is a pretty cool idea

Now that is a pretty cool idea

How feasible is it ?

[Mdtoday]

It's actually quite feasible with a flatbed type router ...or similar setup just has to be rigid enough to keep accuracy and repeatability.
The roller idea is great. Might machine up something similar and have a shot.
If it's just to make a single coil, I wouldn't bother but for multiple coils , yeah, great idea.

Cheers
