Winding now!

[other1152]

got my winder up and running with a huge THANK YOU to everyone on this forum who helped me in one way or another..

i've wound my first coil in the picture, but i'm noticing that my coil is relatively 'loose' the windings move easy when touched and the coil is probably larger then it should be for how many winds on it.. any winding tips you guys can provide would be appreciated! I'm not asking for any of your personal trade secrets or anything just some pointers that would be helpful for a nice neat coil (and i realize alot of this is going to just have to come with practice and time, like anything else..).

thanks again to everyone here for helping me along this far!

Just mind your tension and winding speed (rpm) you'll get better at it as you proceed.

Did you get all the way through w/o breaking the wire?

[other1152]

i broke it two or three times at the beginning in about 100-400 winds. but then i got the hang of it.. i believe the tension was my problem with the looseness. i picked up a different clamp today at the home depot so tomorrow i'll try nuymber two and see how that goes.

Try winding one without the clamp-n-felt thingy, just run it past your finger and use your thumb for the tension. Doing that will give you an idea of what tension you're really dealing with when you wind (it won't burn your fingers) then you will know better what tension to apply using your clamp system.

Are you able to measure the RPM on your winder? the RPM has a lot to do with things too. Faster RPM means you have to apply more tension, slower RPM requires less tension. The CUB-5 which I use on my v3 winder has a button on the front which toggles from Counting mode to RPM mode and using this feature I was able to zero in on the best RPM for my situation.

If you don't have any ability to measure RPM, put a piece of shiny tape on the place you mount your bobbins and take your winder down to a local auto shop, many of those guy's have one of those non-contact tachometers which just read a shiney spot on a pulley of an engine, at least you could get an idea of your winding speed.

Most folks wind in the speed range of around 700-1700 RPM some go faster but have more elaborate winding systems.

thanks i'll try that.

aside from having my brother stop watch me while winding i dont think my counter has that ability.

thanks!

ok, whats the trick to keeping the coil from.. idk what it is even called.. but its pushing out the top or bottom few coils?

looks like this.



what i did was kinda folded it over the coil and wound over it.. but how do i prevent it from happening?


also, about what is normal for a 'hot' single coil? i wraped 9000 winds on one and i'm pretty sure i'll have to pull some off to make the cover fit. it reads 7.1k for anyone interested. how does duncan get away with getting 25k from the yjm fury single coil if its still the size of a single coil?? is it just 3 times as tall?

- confused. (and should probably sleep.)

Put camera in macro mode (symbol is a flower) and don't get too close for the camera to focus to get a clear photo.

You need to set your guides/limiters narrower, you do have guides/limiters right?

To get higher DCR and get the wire to fit on the bobbin, you'll need to go with a thinner wire. I'm sure the Duncan YJM is likely #43 or #44 wire.

{Edit} ...ooops, I guess you don't. I just scrolled up to look at your pictures in the first posts. On DIY winders without automatic traverse (and even with) it's good to have wire guides/limiters to keep the wire within boundarys while winding.

Here's another example of guides/limiters on the Schatten winder although that one could be mounted a bit closer IMHO.

BTW, your pic isn't very clear but it looks like your magnets are sticking up quite high from the top of your flatwork there.

Also, get a hot glue gun and squirt a little hot glue over those exposed AC terminals on your motor there, geez if we don't hear from you for a while we'll be thinking you've electrocuted yourself! (or someone else).

I don't see any guides/limiters in his photo. I agree that's the reason for the wire doing that.

[other1152]

lol ok thanks. i've just been guiding by hand.. when i make the guides do i want to leave about a millimeter of open pole on either side of where i'm winding so that the wire has a place to move out to and not up? would that be a good idea?

[Peter Naglitsch]

Not sure I understand the question 100%, but if you want to know if you should set your limiters so that they are flush with the flat work or a tad within the flat work ie the distance between your limiters being a bit shorter than the length between the flat work, my answer is yes, the limiters should be set shorter than the actual coil/bobbin/pickup you are winding. If the limiters are flush with the flat work you will have a slight build-up at each end of the coil. I lave them about half a mm within the flat work and it works perfect for me.

[other1152]

yes. that was the question. thank you!

You'll want to make them adjustable too.

[other1152]

what would be an easily installed adjustable limiter construction? if anyone has some pictures of theirs i'd love to see them for ideas..

Then you might use the links I gave you in post #8 above.

The (link)-> Shatten <-(Link) style is obviously the easiest to implement.

In the (Link)-> pic's of my v2 winder <-(Link) I took that concept a little further drilling 1/8" holes 90° to the set screw, cut and rounded some 1/8" stainless steel rod (both from Ace/True Value Hardware) and super-glued them in so they extend vertically, then added one across the bottom. I filed a flat side on the mounting rod they are attached to for the set screws to seat into and keep them vertically aligned at that 90° angle of the mounting bar (see pic).
