Running short of time to launch a new video I picked up a nice looking HMV radio reported as "not working" A quick repair and a clean and and I can relax I thought... not so fast Speedy... the transformer is roasted... I decide to rewind it but first I need to update my winding machine. This video is all about updating my winder and rewinding the transformer.

I'm completely blown away at the ingenuity and time you have invested in creating a transformer winding setup that actually works very well. This video was quite fascinating to watch.

@DavidTipton101 Год назад

Thank you lakrfan 49 👍🙂

@terryblackman6217 Год назад

Good morning David from the UK. They say necessity is the mother of invention, and in the case of your home made winder that's certainly true. Absolutely brilliant. I think with a bit more refinement you will have a great little tool that should come in handy for future restorations. Looking forward to seeing your next installment. Hope you are well. Terry

@DavidTipton101 Год назад

Hi Terry, thank you. I am good thank you. I have purchased two more stepper motors and will go with a new design, a bit smaller and neater and hopefully accurate enough to get a more consistent finish. I would say though the finish was pretty good all the same 🙂

@terryblackman6217 Год назад

@@DavidTipton101 I thought the finish was superb.

@ry491 Год назад

Wow David . I am speechless . That was sheer brilliance combined with incredible patience . Good to see you at the bench again . Lovely looking radio too . I bet that's a keeper ! Just restored a similar radio but thank god the transformer was ok in spite of shorted filter caps . Never had the guts to attempt a rewind but hats off to you for doing that . Now to start my next project . A rather nice 50s communication receiver . Fingers crossed the trans is not cooked ! Best wishes from Thomas in UK .

@DavidTipton101 Год назад

Hi Thomas, It's a cracker looking radio, the case is a work of art. I haven't had a lot of failed transformers lately, they come in waves it seems. I was hesitant to start rewinding transformers but it's quite rewarding and pretty straightforward really. Good luck with your coms receiver. All the best to you too Thomas 👍🙂

@jeffreyhickman3871 Год назад

I’m glad you’ve got all the “know how”, and the wire winder for this job. It is usually the end of the line for the radio 📻 when a transformer burns out (financially). You’d have that transformer rewound in, probably 5 minutes, and all 1500 + feet of it (20, to do it correctly, if it takes more time). I’d be there a day and a half, trying to rewind that transformer by hand 🤚, and it would not look as good. Just be careful not to break the wire at any point. Re-laminate the wire before winding. I don’t even know where to buy that wire rewinding tool. I’d probably be looking at $1500.00 for it, new. Your friend, Jeff.

@DavidTipton101 Год назад

Thanks Jeff, you are correct, a failed transformer is often the end of the line for a radio, the winder is pretty cheap, a bit over $100 on eBay 🙂

@Leo6009 Год назад

Some great skills and materials used throughout this project. Removing the enamel from the copper wire for soldering. The use of the kapton tape and heat shrink. A good variety of materials used gives reliability. 😀 The spool winding reminds me of fishing line spool on a fishing reel, how it feeds on evenly side to side. Room for improvement there but early days. 😀 The ingenuity and patience got the result. Enjoyable to watch! Thank you David. 🔧😁🙋‍♂️👍

@DavidTipton101 Год назад

Thanks Pete. Good point about the fishing reel and plenty of room for improvement, I hope I get another bung transformer to try out the improved version 😄

@mrbyamile6973 Год назад

I'm a horrible person Dave. As soon as you showed that toasted transformer, I wanted you to rewind it. When you found a possible spare I was disappointed and when you realized it was to large I was happy because that meant rewinding was back on the table for repair. I'm almost ashamed of myself for rooting for rewind when it made you go through such work. Thanks for this content, wonderful.

@DavidTipton101 Год назад

Not a horrible person Mr Byamile, my videos are like riding a roller coaster of emotions, the dizzying highs the devastating lows... I should write book covers 🤔 Actually I was relieved when I thought I found a doner transformer then depressed when it wouldn't fit, the opposite of you 🤣🤣🤣

@ervwatson4988 Год назад

Dave, Your engineering skills are far beyond anything I would attempt, but I love watching you solve problems. Your ability to explain complex matters so I can understand is what makes your videos so great. Even though I would not attempt some of the things you make look easy, I still learn a lot and I am encouraged to attempt more than was previously comfortable for me. I never miss your videos. Thanks

@lurkersmith810 Год назад

Never apologize for showing us something you hadn't intended. One of these days I may brave my way to rewinding some 1929 transformers, and what I've seen here may help if I can retain and adapt it well enough!

@DavidTipton101 Год назад

Haha... yes I got of track there but a successful video on rewinding emerged. This rewinding lark is pretty easy with a bit of experience and a cheap hand winder from China. The wire is a bit pricey but I think worth it in the end especially if you can save an early radio for the dump. Good luck if you try it Lurker Smith👍🙂

@viorelparaschivoiu8882 Год назад

Well done! I had to make a transformer in seventh grade for a course. By hand. As in hold the bobbin in one hand and loop the wire around with the other. We had two choices of material to make the bobbin Presspahn (a type of insulator Kraft paper) or 1.5mm phenolic sheet. Counting to 2750 (primary for 220V) is tricky when you have to remember where you were after dealing with some incident. Wire was .1mm for the primary so it was easy to have it come loose, unwind and create a mess. Mine worked (majority of the class didn't) but have never tried it again. You have reignited my interest now after 40 years and since I have a signal generator with a dead transformer I might get to do it again. I remember we had great trouble trying to wind evenly and tightly across the bobbin and the only way to do it was to put a sheet of baking paper between layers. That way each layer starts fresh and the paper takes away some of the unevenness of the previous layer. We didn't have varnish so we relied on the tension on the wire to keep the windings really tight.

@DavidTipton101 Год назад

Thanks viorel. Hand winding sounds like a nightmare, I would lose count for sure. Good luck with your transformer 🙂

I am truly amazed by the way that you consistently come up with ingenious solutions to problems and the "nothing is going to beat me" attitude that you display. The quality and attention to detail that you show on every one of your "adventures" is something that we can all learn from. I have tried to follow your footsteps by making a conscious effort to pay more attention to detail and I have noticed that it is helping me in my daily work. You are truly a hidden gem of RU-vid and I believe that you should have 10 times the subscribers that you have now. Please keep sharing as it always a bright spot in my day whenever I see that you have released a new video. I also like your sense of humor. When I saw the "Turnminator 2" sticker at 21:44 I busted out laughing. Thank you so much for sharing your journey with us.

@Spasticlemur Год назад

As you were rewinding the transformer, at the 42:00 minute mark (approximate) you said "It's not going very well." Good Gravy, man! You did a helluva job! I don't know of anyone, anywhere, who has designed from scratch, a custom transformer rewinding workstation for the hobbyist/home use like you did. While the applications are limited, as most replacement transformers can be purchased, I don't know of anywhere one could purchase a replacement transformer for an antique radio, so they have to be built from scratch to perform correctly. That rewinding station is genius. You could most likely refine it into a transformer rewinding workstation that could be patented and sold. Yes, it may look like an octopus with too many arms on your workbench, but it WORKS, and that is what is important. The micro switches, along with the stepper motor and stepper motor programming is simply genius. Give yourself more credit. You come up with some of the simplest, yet amazing solutions when you are under the gun.

@DavidTipton101 Год назад

Thank you Grouchy Guy. In my defence when I said that it was running too fast and leaving gaps, it should have been better that that but I was VERY happy with the end result. Replacement transformers are getting rare and I was chucking them out like everyone else, I couldn't keep doing that, beside I was fitting similarly aged transformers to the one that had failed. I will improve the design in the future. Thanks Grouchy Guy 👍🙂

@janmussche6815 5 месяцев назад

Hai David, you are really getting famous. Whenever I search on the internet for a radio you restored, at least 1 result is from your video. The idea of the carriage out of a printer was genius. Yes, you can control it much better with a stepper motor than with a simple DC motor. As you found out as well, a DC motor runs either too fast or not at all. The result is great, the windings are nicely placed next to each other, a great success. Thank you for yet another video.

@DavidTipton101 5 месяцев назад

Haha... thanks Jan. I always wanted to be famous 😄The printer worked alright, superseded now but a simple solution for the occasional rewind 🙂

0:50 Spotted that long-gone call-sign (2)HR in the NSW grouping. As I mentioned once before, 2HR was a station located in Maitland that went belly-up around 1950(or could've been earlier). A new station, 2NX replaced it around 1950 with studios and office originally in High Street, Maitland and transmitter located at Bolworra(a Maitland suburb). The old 2HR transmitter site was near the railway line, some distance out from the Victoria Street station at East Maitland, on the left as you rode to Newcastle.

@jeffreyhickman3871 Год назад

I guess I’m getting ready to see part 2 to this. The next round will probably be new tubes and capacitors. Again, for your sake, I hope 🤞 the dial cord in this radio 📻 does not need to be replaced. That’s logical to have to, but what’s worse, is to put the radio all back together, thinking 🤔 you’re all done, to have the dial cord break. Again, after dealing with a burned out transformer, unwinding, and winding up 1500 + feet of wire, would be what I’d want to do in a day. Your friend, Jeff.

@DavidTipton101 Год назад

Hi Jeff, the dial cord is broken and the capacitors have been replaced recently by someone else but there is still plenty to do in part 2 🙂

@jeffreyhickman3871 Год назад

@@DavidTipton101 I just hope that the capacitors have been installed correctly. Like bicycle 🚲, or car 🚗 tires, they are not often directional as far as tread design when installed (but sometimes are). Capacitors are a round cylinder, and don’t seem “directional”, but they are (best way I could speak 🗣). There is such a thing as installing a capacitor backwards. All will seem well, until ya click the ON/OFF volume knob to “ON”. Once the “click” is heard 👂, will come a resulting “POW”, or “POP”. By now, you’ve probably blown out everything on the board. It could be one ☝️ capacitor (a good one), two, or several capacitors (probably good ones), or this could blow them all out. The only time ya might not mind, is when an unwary customer (or repairman 👨‍🔧), has replaced one, or several capacitors, ya plug 🔌 the radio in, turn it on, and “POP”, to find out all ya blew out, was OLD, or ROTTEN capacitors. At least, that wouldn’t bother me. Your friend, Jeff.

I have used specialist transformer suppliers who custom build for certain projects et Buying or sourcing a second hand unit sometimes works but for more 'special' repairs/renovations I tend NOT to go for them. 👀

Hi Arthur, thank you. The very early transformers fail with monotonous regularity and I had a few rebuilt by a chap who has since retired from rewinding, he did a beautiful job.

I really find the transformer winding and calculations very instresting.... Maybe if you print an accurate bush, to press on to winder shaft, to hold plastic transformer frame more accurately, it may wind on more uniformly. But your windings looked very good.....I hope they are teaching this in our schools. Maybe one day we can get back into manufacturing in Australia again. Great work, and thanks for you channel.

Thanks for this video! You gave me some idead to implement with a microcontroller, regarding this same application. Wonderful job, ad maiora!

@DavidTipton101 Год назад

My pleasure quantum_ghost. Playing with the Arduino was a lot of fun. Good luck with yours 🙂

@chrisclark6192 Год назад

Hi David. Great stuff as always. A superb demonstration of your knowledge, skills and patience. The transformer outputs turned out to be spot on (although not under load) at the first attempt. I must admit that on a couple of occasions I thought that the wire would snap during the winding process. Your rewind set-up is pure genius. Again superb work. Look forward to seeing the next episode. Cheers Chris.

@DavidTipton101 Год назад

Thanks Chris, the wire is pretty hard to break even the thinner gauge wire, I will add a strain relief mechanism next time and a slow start feature to further reduce potential breakages 👍🙂

You really knocked it out of the park with this one, Dave. I had to pick up my jaw from the floor multiple times during this video. Be careful though, because with this quality of work you'll be attracting requests to rebuild transformers from all over the world. ;-)

Thanks Retro Tech Restorations, I have had a few already 😄

Hi Dave, that was one fried transformer. I used to get my students to make similar things out of old printers and Arduino's, the kids loved doing something practical with electronics and programming. The stepper motors make all the difference in such devices. I've been offered an industrial transformer winder with 3 feeds. It'll need a truck to move! However, seeing your solution might be a better starting point. Hmmm. If we can get it out there that a dead transformer is not the end of the radio all the better.

@DavidTipton101 Год назад

Hi Andrew, it sure was fried. That would have been fun for the students, it was for me. The winder you have been offered would be terrific if you have somewhere to put it but I bit over the top I guess, it might be three phase as well. My prototype will be redesigned from the bottom up, I will keep the winder but start again otherwise using two new stepper motors and a new wire guide, the printer part will go. It did a reasonable job though and if folks want a cheap method it works well enough. I was going to try a PWM motor controller on the DC motor but wanted to go stepper eventually anyway but it would only require an under $20 spend 🙂

@CXensation Год назад

Use a PWM controller for the DC motor instead of the voltage regulator. That way the motor can move slow without losing torque and stall.

@DavidTipton101 Год назад

Yes that would have worked pretty well CXensation and if others want to use that it would make a cheap winder. I didn't pursue that option because I wanted to go all stepper motor eventually. But a good solution, thanks CXensation 👍🙂

My head just exploded. Ouch! I envy your electronics skills. Very well done, David. Kudos!

@DavidTipton101 Год назад

Thanks Otto, sorry about your head 😄

ingenious work with the old printer mechanism. I like it.😀 You deserve a lot more subscribers.

@kennethgibbons366 Год назад

Hi David - there is really nothing that you can't achieve! Very impressive!

@DavidTipton101 Год назад

Thank you Kenneth 🙂

@steelcity321pb6 Год назад

Hi Dave, Now that is what I call ‘Ingenuity’! For sure your ‘Mark 1’ coil winding device has a few teething issues, that is to be expected when making something new, but you are definitely on its case. You know exactly where to continue making improvements. I’m convinced ‘Mark 2’ will be a superior device. Bravo! I love what you are doing my friend! Best regards from Phil.

@DavidTipton101 Год назад

Hi Phil. I will rebuild this into a better design with a more predictable outcome hopefully. Thanks Phil, take care 🙂

@greggsvintageworkshop8974 Год назад

What a beautiful job on that transformer Dave, you do amazing work sir!

@DavidTipton101 Год назад

Thank you Gregg, hopefully I will see you do one one day 👍😀

@TheUltimateRecycler Год назад

Brilliant Video Dave, I really did enjoy that whole journey and I think it has made transformers just a little less scary to me! 👍👏🤣

@DavidTipton101 Год назад

Hi Chris, thank you, transformers are getting a little less scary for me too 😄

@mracoomber4908 Год назад
