I found an old auto-transformer that desperately needed some TLC. So in this video, I'll give it a freshen-up. Let me know if you like this kind of video format? Schematix
That rustoleum paint is the business for easy spray can based paint jobs. I was taught that spray jobs can be improved by warming the surface of the metal (in the sun or a low temp in the oven) and standing the spray can in hot water (with a weight on top) improves flow from spray cans and vastly reduces likelihood of paint runs. It works well. You probably know this already, you look smarter than me. Good vid mate.
I have used autotransformers extensively over the past 40 years for doing burn-in of high-reliability resistors. They are very rugged and reliable power sources but we found that fusing both input and output was wise. We ruined numerous transformers due to loads that shorted and the transformers can smoke if you don't have the input fused.
Great to see a UA-camr with 'used' tools ;) So many DIY channels have brand new shiny tools, to which I always think ' if they are so experienced, how come their tools are so shiny' ;)
Nice mate, that looks really good, the analog meters are a really great look for the age of the varriac. mines a little newer and i installed a digital meter.
Nice job, rivnuts are a good addition. Plenty of these Claude Lyon auto transformers around, not sure if there are still available from RS Components, but they sold them for a number of years
Should have change the nametag to "Schematix Model 1" or similar given all the work you put into this. You managed to improve on the design and use of this transformer. Well done and thank you for sharing. P.S. Love the scene of mountains and sheep at the beginning.

Good practical demonstration of upgrading an autotransformer. I like the analog meters.

Very nicely done. Not too much or too little talk or unnecessary camera work, very easy to watch.
Upvote for making a crimp using the correct ratchet crimp tool. Unlike the 6 million geniuses on UA-cam using pliers/hammer/solder…
I like what you did to the unit. It would be awesome if you tell us what parts you added for modification.
Wow... that was textbook and high quality! Great re-build!!!
i appreciate the way that you restored it. by using rivit nuts ,wire terminals and meters. i enjoyed and leaned some

It is so satisfying making old things new again! Well done, sir.
Excellent restoration
What was once old, is now new again!

Great video. Nicely paced. Kinda had me mesmerised watching you do a professional quality refurbishment of your Variac. Like the format! :)

More videos of this type ... I always learn how to use new tools

Ground connection in the box: the tooth lock washer should go under the nut. Or just use a second one for locking the nut.
needs + your initials after the MK on the serial plate now---
Very enjoyable - nice to see old stuff resurrected for CURRENT use. Shades of Mr Carlson.
