1929's Live Steam Naumann Machine Restoration - Will It Ever Work Again?

In this video, I restore an old rusty live steam machine Naumann made in Germany in 1929.
More about the restoration process: It was highly challenging, but the end result is gratifying. I learned a lot about steam machines and how they work. I was motivated to see if I could make it work again, so I put a lot of soul and effort into this restoration project. When I saw it, I was shocked at how bad it looked; it was full of rust, cracks, and broken parts!
If you want to learn more about this antique German steam machine model, I encourage you to watch this video.
More about the steam machine: The machine was made in 1929, and thanks to the Naumann company, the year can be seen on the boiler. I found out they were making sewing machines, but I couldn't find anything related to steam machines. Prague 777 made the stove in the former Czechoslovakia. The machine model was probably used by a salesman to pitch his industrial technology or by a teacher in mechanic schools to make demonstrations and teach students about this fantastic engineering at that time.
At the end of the video, I made a test so you can see how it works!
I hope I have caught everything, but if you have any questions, you can comment, and I'll get back to you! Cheers! Johnny.

Hi folks! I had always dreamed of having the chance to restore a live steam machine like this one, and my dream came true! It was probably one of the most challenging projects I ever had, but I reached my goal, and the goal was to make it work again. And it does. With some more adjustments, it will fly around! Opened for discussions/suggestions! Cheers! Johnny

The timing on the valve in the valve chest needs adjusting so it uncovers the ports correctly at each end of the stroke, which is why it's struggling to run in the end with little power behind it, and seemingly blowing a lot straight to the exhaust. You can also hook up a length of silicone rubber tubing on the exhaust piping with some zip ties, and run it to a container so it's not going all over. Restoring steam stuff is tricky so this is an admirable effort.

As a steam-hobbyist, I might add the following comments:
You should have tested the boiler to at least twice the pressure of the safety-valve, doing otherwise is flirting with disaster.
To improve performance, you should wrap the steam-pipes with thin rope as insulation (aka lagging), without you are loosing the benefits of the superheating (the pipe going through the flame again).
Retrofitting a displacement-oiler allows for continuous lubrication, btw, your oil is likely unsuited for steam, as it breaks down under the temperature and humidity, try steam-oil from Wilesco, it's pretty common and easy to get.
As mentioned, your valve timing and stroke are off, setting these is almost an art, but can be learned.
The handling of steam-exhaust is designed badly, changing the piping to discharge the exhaust-steam to bubble through a small container with water will make the whole thing much neater.
You also seemed to have missed packing the gland of the valve-chest. A small temperature-resistant O-ring or a roll of PTFE-film might do the trick, as you can hear the whistling of escaping steam.

Он на Угольной тяге, мой пыхтун Дорогой!
А от Луги до Питера всё столбы, провода!
Моя Юность Советская ты со мной навсегда!

It is wonderful that there are craftsmans such as yourself that keep as well as maintain these awesome artifacts

I can only *imagine* what you could do with TWO of the same antique items. One rebuilt traditionally, and the other given 'today's' gaskets and such!

Прекрасная работа!
Удачи! Мира! Добра!

It's 1:15 am and I should be in bed. But watching your videos is so enthralling that I just had to see.
As always, a great job of restoration.

Благодарю за такое большое количество языков, которые в субтитрах используются! Мир вашему дому!

I had no doubt it would work again, in your capable hands. 👍

[MrsIsmena]

Effect before and after amazing... 😮 Great job❤

Какой интересный агрегат. Скорее всего немного не настроены фазы открытия золотника, поэтому машина не набирает обороты.

[raymurphyii]

I so enjoy watching these videos. I only wish I was blessed with the gift you have to remake these things.

Luv your videos! Soldering is done by heating the parts to be soldered to the point where solder melts on the parts. Flux is usually required. Silver solder might work better in this application.

[samanthadean]

Never heard of this device before, but the restoration was awesome!!!
👍🏻👍🏻👍🏻❤️❤️❤️

[garymucher]

Nice refurbishing project. It looks very good. If I can make a suggestion, use some quality paste flux whenever you are soldering such things. Especially copper on copper, or copper on brass. Even copper on steel will flow better. The solder will flow out very nicely... Thumbs Up!

Merci de nous avoir montré une si belle restauration ! Félicitations !
Je suis impatient d'en voir d'autres !!

[andresdelafuente]

espectacular transformación!! una joya de antiguedad. felicitaciones!! saludos desde Buenos Aires!

[hlyzzfm]

أروع في هذا الترميم هو أنه سريع.. لا توجد مشاهد طويلة مملة..
أحسنتم..

Steam machines are so cool, thanks for the video!!
