Counting turns on a mini-lathe winder

[copperheadroads]

In the next few months & going to make a new winder for doing my handwound stuff .
I was going to use one of these cheap mini-lathe ,which I already own Mastercraft 12-in. Lathe with Chisel Set | Canadian Tire
I'm just curious & (I haven't removed the cover on the end of the shaft to see if i can mount a disc for a sensor )
how to rig a counter to this ?
Has anybody used a similar lathes for a winder ?

I have no Answers, but do have some questions, you may be able to answer along the way.
Can you get the lathe to turn the right direction(bobbin top going)?
I was always afraid to buy one because of the rotation issue?
That looks identical to the one Harbor Freight sells.
Thanks,
T

Thanks T
I'm sure it is the same as the Harbor freight
It's just a popular brand Up here in the north
& unless you can reverse or reverse wire the motor It wont turn in a opposite direction

If it's like the one on the photo you can just mount a reflective stripe that goes 1/2 way around the back of the faceplate and use a Fairchild IR sensor pointed at the stripe.
If it's a DC motor you just need to flip the motor leads via a DPDT switch.

You could glue a magnet on the back of the faceplate, mount a reed switch on the drive housing, and run the lines from the reed switch to a dry contact counter such as the one below:

6300-0600-0000 - REDINGTON COUNTERS - COUNTER, 8-DIGIT LCD | Newark/element14 Canada

Very clean and easy setup.

Just another option.

No cheap shots on the price of the counter. It's not cheap, but it has a 7 or 8 year life cycle on the battery it uses assuming a 24/7 type usage schedule. And you already know the cheap guys us the old calculators that bounce.

Edit: Oops on the battery life statement. Just looked up the data sheet. . . 15+ years. Sorry about that.

I've seen that lathe on sale at CTC within the past few months at ~ the $99 mark as well.

Thanks guys
I'm going to be looking for a little larger display on the counter ,The Cub3 on my old winder is just too tiny

Get yourself a "Preset" counter so that you can shut off your winder automatically at the end of the cycle.
12V 24V Preset Scale DIN Digital Counter Relay UP&Down | eBay
I would also urge you to pass on the reed switch variation in favor of a real sensor that you can control the dwell on and eliminate the bounce.
get a QRD 1113 and 1114 from Mouser.

Great thread, I have been looking around for another winding machine and there are some in begginers section looking as well..

[copperheadroads]

Cool .........lots of Ideas & It won't take long to build this winder
I would like to have a 5 digit counter ,but it guess it's not a must .
I see the 4 digit counters really cheap

I saw a winder made like this, and in fact, was going to make one myself. What the guy did was get a proximity switch and secure it to a bracket facing the faceplate. Then he glued a small neo magnet to the faceplate. Every time it turned the proximity switch would close and advance the counter.

Because I was going to build a winder like this, I ended up buying a bunch of proximity switches. I figured extras can't hurt and they were relatively cheap.

So if anyone is interested, I have six Balluff, model BES 516-383-S4-C switches. They look like this:

I'm going to keep one of them, but I'll sell them for what I paid for them, which is $25 each. Shoot me a PM if anyone is interested.

That's what I useed on my old winder & it works great
I mounted mine through a L bracket facing a lexan disc that I machined & I used some aluminium tape for the sensor to detect
thanks .....I will keep the offer in mind
