I bought the plans for winder #5 and just finished it last week. It's fantastic! I love it. Best $15 bucks I've spent in ages. The shape of the cams that come in the instructions is priceless.
You always have great content, thank you. I have been pondering building an automated winder for a while with Arduino IDE. I'm looking forward to the reveal of this project.
Killer project Chris. I've got a few old steppers and uno boards that have been looking for a purpose. This would be a good one. I'm thinking you could potentially add a series of input buttons that would select between a handful of programs... You could wind a set of 3 single coils and a handful of humbuckers without every having to hook the PC back up...
This looks like a really interesting project, Chris, and I'll be waiting for the next parts. As a BTW, I developed a wire tension measuring system after you remarked in an earlier video about your pickup winder using felt washers from a cymbal stand to provide wire tension. I tried two different approaches, and both work quite well so far. One shows 'relative' tension, so setting tension is repeatable. The second will be able to set an actual tension value. I started with the idea of simple and repeatable. There are many approaches, I'm sure. I tried for fewest components and low cost. I hope you won't mind if I send you the details when they're satisfactory, by way of saying "thank you."
Absolutely. I'm working out the tensioning right now. The challenge seems to be the shape of the bobbin and how it changes the tension as it spins. I'm looking at a magnetic tensioner as a way to account for the changes in the shape and its ability to supply a value I can plug into my turn count formula.
@@HighlineGuitars Chris, yes, that's a sticking point. You mentioned a magnetic tensioner - that's one idea I've prototyped, and I've also devised an optical sensor. This is based, funnily enough, on a very, very old idea. I've been using an automated counter/motor control module right along, so I've with you on that. I haven't come up with a really obvious way to incorporate a "tension signal" input to that module, although there are a couple of possibilities. As a side note, I'm also looking at variable-frequency AC drive, vs DC for the winder. (Only because I have the "lumps" for both on hand). There are a couple of options re: tensioning - one is measuring the change in wire tension, and incorporating that into a "feedback loop" that adjusts the tension according to that input, in real time (Speed is the stinker with this one). Another option I am still exploring - it's on the list, so to speak - is using the winder axle position (and consequently the bobbin position), rather than trying to have a very fast auto-tensioning adjustment mechanism. This would also incorporate the traverser position, of course. It's possible that keeping a mechanical cam in the process might simplify this somewhat. I'm not ruling it out - the math for simulating cams is non-trivial. Once upon a time, I did a bit of engineering research, and had to build one-off equipment. That has left me with a few ideas, but I'm not quite there yet with that part of it. I am also in the process of re-arranging the winder's main parts - not quite a rebuild, but close, in order to make the tensioning/traverse measurement and adjustment easier, or should I say have more room for the mechanism. I will keep you posted.
@@HighlineGuitarsChris, I think we're on a similar track with bobbin position. I woke up, middle of the night, with an idea for a moving-magnet tension adjuster that's so ridiculous it might just work. If it works at all, it won't be hard to control from a rotary position sensor, possibly with an Arduino or other microcontroller/PIC in between. I'm getting a small spool of 30 AWG wire for testing, instead of using 42 AWG on 'first attempts.' I'll give this a try, keep you posted if it shows any promise, and keep watching.
Excellent idea! I saw some winders with two stepper motors (one for the traverse and one for the coil): do you think that there are pros and cons in using the stepper for the coils? Thanks!
Stepper motors can't run at the speed needed for winding a coil. The motor spinning the bobbin is probably a servo motor. They work great for this but are really expensive.
What software, program are you using to write the gcode? I too have considered doing something similar but thought to get the gcode right would be the biggest challenge. You got my full attention with this project 👍🏼
Is there a problem with your cam method? I bought those plans recently but haven’t set up the cam yet. Just curious why the need for cnc if the design is already autonomous?
I never said there is something wrong with the cam winder. On the contrary, it works great. However, I am always looking for new projects to talk about on my channel.

I subscribed to the channel long time ago and every minute has paid off. Thanks for sharing.
Awesome! Thank you!
Awesome, really looking forward to seeing how this pans out! I for one love the more in-depth content from your channel
That's an awesome project, Chris
You always have great content, thank you. I have been pondering building an automated winder for a while with Arduino IDE. I'm looking forward to the reveal of this project.
You truly are amazing
This is great. I have a bunch of old nema 17s and a control board... Can't wait to see what you do!
Have fun!

Thank you for all the information you provide!
My pleasure!

@@jimbaritone6429 In the next episode for this series, I plan to address tension and the possible ways to apply it to this winder concept. Stay tuned!

Do you ever sleep?? Thanks much for your video's. They are appreciated by many
Excellent idea, And an excellent video thank you for sharing what you have learned in what you know thanks.😉

@@HighlineGuitars thanks Chris, i was suspecting this but i was eager to ask you to be sure. Kudos for your work!
If you can pre-program an automated scatter wound pattern in a DIY device, that would be pretty awesome. Aim high! Good luck!
I can and I have. Stay tuned!
C'mon, admit it.... you are a nerd, like me, and you just love to build stuff lol. I really enjoy all of your builds!
Looks cool. Are you planning to have a speed sensor on the rotating motor to use as an input to the traversing motor?
No. Both motors will be controlled by the g-code file sent to the controller.
What software, program are you using to write the gcode?
I too have considered doing something similar but thought to get the gcode right would be the biggest challenge.
You got my full attention with this project 👍🏼
I write the g-code myself in a text editor. More will be explained in future episodes.
Hi Chris
Have you ever thought of using a raspberry Pi to control your code?
I’d rather use my laptop.
It's amazing.
How about an RC servo for the traverse sweep?
Is there a prefabricated mechanism utilizing an RC servo? The reason I used a z axis slide is because I didn’t have to make one. And, they’re cheap.
Chris, on #5 do you have one cam for all types of bobbins. Or different cams for each bobbin?
Different cams for different bobbins.
Is there a problem with your cam method? I bought those plans recently but haven’t set up the cam yet. Just curious why the need for cnc if the design is already autonomous?
I never said there is something wrong with the cam winder. On the contrary, it works great. However, I am always looking for new projects to talk about on my channel.
What's the cost of that control unit, the two motors? Is the G coding hard to learn? I mean, I coded some websites :')
All will be revealed eventually.
I didn't realize you had so much programming to do for CNC
Yes, I do. However, there are some clever tricks. Stay tuned.
If only I had the space to do this. Studio apartment...
