PERFECT micro coils - start to finish video using the darkzero coil jig

[UKPaul]

DZ - I have some ideas on combining the winding system with the simplicity and ease of machining of your fine little jig.

I have to sleep now unfortunately but will try and post some sketches when I am back in the office in the morning.

BTW I love your jig and it wasn't my intention to disregard it but can't shake off thinking about the benefits a winder offers.

If this were available in metal I would have no problem buying it… It is a really awesome idea



Thanks

Throwing this out there, wire length restriction under the screw may be an issue.

Well, as promised, here are the pictures of my 5-minute, homemade micro coil jig.
I just went to the garage and found some scrap wood, sanded it smooth (out of boredom).
Then, I found a trim nail that was fairly close in size to a 1/16 drill bit, popped it in and cut off the head.

The unfortunate part about my jig is that I have to tie the kanthal to the screw, thus wasting about two inches of wire each time.

Looks horrendous, but gets the job done quite decently.

How bout using a flat head wood screw with a washer, and capture the wire between the washer and screw head?

My only fear with that is since I'm using wood (no metal readily available), the constant screwing and unscrewing of that screw would lead to a degradation inside the wood fairly quickly.

Yeah, that looks like soft pine. If you don't over tighten, it should last a while tho. If you could get hold of a piece of hardwood, it wouldn't strip out as fast. Doesn't seem it would have to be tightened very tight to hold the wire tho.

Instead of the screw to hold, couldn't you drill it out all the way through for a long bolt, and then use a washer and wing nut? Then you slip the end of the wire under the washer and tighten the wing nut. That might hold it. Or use two washers and slip your wire between them, then tighten.

Back in the day, we used to use one of these:



To make these:




It was super easy to do, inexpensive, and accurate with a little practice. I checked out mine and it is for smaller diameter post but the wire gauge looks about right. I am going to see if there are any available for an 1/16 inch (approx) post.

Ooh!!! That sounds like an easy thing to do!
Now I know what I'm doing when I get home.
Thanks for the tip!

You're welcome, Johnny. If you are in fact using soft pine, the bolt head could initially be tightened enough to dent the wood a bit and give a slight recess so when you actually use it to make a coil, tightening the wing nut won't allow the head to turn. (I'd prolly use a hammer on the head of the bolt to get that recess, though. )

Just another idea, what if you opened the door to the REO and there was a hole maybe drilled into the top where one could stick a post and another spot to secure the end of a wire.

A wrapping jig could be built into the REO?

The McQyver juices are flowing now !!!!!!
REO minds putting out more plumes of smoke than a sub ohm atty!!

Whipped this up this morning, and wrapped a 1.3Ω, 5 wrap coil with 30g Kanthal. Worked pretty good.

Looks great! I'm going to have to start from scratch this evening and make one like that with the washers and nut.

 

[oplholik]

I used a 1/4-20 carriage bolt on mine, and pulled the head into the wood. Didn't have a wing nut to use, will have to get one on my next run to hardware store.

I too have used that tool a LOT. I have used both the manual (squeeze), stick, and electric ones. Note that they are still used in the Telephone business. Having wired up telephone central offices, I have a lot of experience with them.

You can buy them here. They have various bit sizes here as well. I am going to have to see if I can figure out what size(s) to get.
