I use many parts of useless TV tubes in the making of my tubes. There are tens of thousands of these tubes around from the days of tube TV sets and they have no collector value. Certain tubes are worth rebuilding but most tubes can still be purchased for less than it would be practical to rebuild. Modern made tubes are vastly better than early tubes. The only tubes now made are special purpose tubes and these are quite impressive in their specifications.
The Internet is a miracle...the public forum for Free knowledge. Thank you Ron for an excellent presentation. I never gave tube making a thought when I was young, never thought it possible, but thanks to you I am on to a new hobby!
The whole idea is to make tubes, not learn to be an accomplished glassblower. I went through over a year of trying to do it by hand and failed miserably. I just don't have the steady hand and calm thought processes to be good at it. All that changed drastically when I got the lathe built up. I actually began succeeding in making tubes! I still have a lot of trouble with the glasswork but am at least not sitting around watching TV all day! Freehand is not something everyone can do.
Hi. Just found this channel from a recommendation. Straight to the point. You said this was a home-built glass lathe ? Do you have plans we can buy to make one, please ? Glass lathe are expensive, and we don't always need a $5000 one to achieve something usable. That's where a solution like this comes in hand, especially in low income country. Thank you for such content.
Thank you so much Ron. That inspiration i was looking for. I would like to live in your neighborhood :P . I watch almost every day if there is something new from you is in your channel. Greetings from Germany
Go to my "tubecrafter.com" website on the wayback machine. I wasn't getting any views so I had to delete it for financial reasons. LOTS of great info on the website!
The compressor is a small diaphragm type commonly used with paint sprayers. It is small, 1/2 cu/ft per minute. Maximum pressure is 5 psi. The regulator is made from a standard pressure regulator by plugging the feedback port and using the internal spring as the reference. (The outlet feeds to the inlet for the bypass.) It is essential that there be no leaks of course.
Hi! Interesting, and i thought that the output tube would be so hot that any solder would melt but that is obviously not the reason. Thanks for this, i will try that out one day!
Hello! Yes. A sleeve with a tapered end to force the O ring against the dif pump pipe is fit over the end of the pipe. I have also simply soldered the tube to the dif pump outlet using stainless steel solder. That works really well and makes a hermetic seal.
The hydrogen would work fine however producing it in sufficient quantities would be quite expensive compared to propane or natural gas. Also, hydrogen torches are built with different orfice diameters than propane or natural gas torches. This is because of the much faster burn rate of the hydrogen-oxygen mix. Trying to use hydrogen in a natural gas torch results in problems with flash back.
There is a channel called NOBOX7 and he built a banging hydrogen torch system that would be easy for someone with your talents. Actually you can purchase the plexiglass and sealed metal style oxyhydrogen generator . I had built one a long time ago and used acetone sparging to cool the flame because it got too hot. It is the best for brazing. It seems this comment section is a goldmine for finding what is interesting. thank you again.
I disagree. There are several procedures in tubemaking that require multiple alignments at once. You can't do that by hand. You could make some kind of fixture I guess and not use a lathe, but the lathe makes the job a snap. Also, to get to the experience level in freehand glassblowing that it takes to do even the simplest tasks takes far longer than if you have the lathe. Freehand glassblowing is an art and not everyone has the steady hand and calm thought processes to be good at it.
Unfortunately, the parts were all from ebay, which means they are not commonly available. It would be impossible to make it now since the parts are not available.
I have two exactly the same diffusionpumps but i havent got time to figure out how to connect the outlet since its just a straight tube and not the usual vacuum fittings. It seems as you use some similar principle as when you connect a tube to the system with that nut and o-ring, correct?
Кислородные аппараты не очень дешевы. Думаю сделать электролизный аппарат с получением раздельно газов H2 and O 2 в устройстве где роль мембраны будет выполнять перегородка из стеклянной пластины с V - образными каналами. Два гидрозатворы и клапана будут защищать лот попадания смеси если они получатся. Вакуум до 10-5 можно получить не только известными и признанными способами но и способом когда малое количество остающихся молекул будут удаляться способом давно известным но не использующимся в технике высокого вакуума. Это вызывает много вопросов, один из них - почему до сих пор не использован? Просто, нет паров масла, дорогого турбо насоса.
You will have trouble making enough oxygen using electrolysis. You need 5 to 15 liters per minute depending on the size glass you are working on. The machines are low cost in USA.
Question continued from previous comment.... Do you suppose it practical to recycle used tube components or that old tubes could be renewed or rejuvinated? How about tubes that have had damaged envelopes and lost vacuum? Could something be done to rebuild them or have they been totally polluted with oxidation to have any further value? Also, why cant a commercial manufacturer build an equal or even technically superior tube compared to the tubes of yesteryear?
hi i really love your work, on glasswork and i have been following your channel for a long time now, i wanted to ask you how did you make both chucks spin at the same time if you don't mind giving me a simple summary please if that is possible
A splined shaft is located on bearings on the back of the lathe. The shaft is connected to the motor. The two chucks have gears that match to the splined shaft. One of the gears on the shaft is a splined rider that moves along the shaft when the movable chuck moves.
Hello and thank you for all you videos! Is it possible to use oxy-hydrogen instead of oxy-propane? It is getting more and more popular, and solution seems to be very clean and compact.
@@glasslinger Yes just saw it, that is very helpful, thanks! What would be a recommend flow of hydrogen/ oxygen for same performance as propane? Just want to estimate which generator would work... 5 lpm?
@@ostroumovgeorgy8247 5 lpm would do fine. Note that you have to have plenty of oxygen to burn it. Since water is 2 H plus an O you will need 2.5 lpm of pure oxygen. Another thing is the pressure. You will need about 5 psi on your hydrogen into the torch. Same with the oxygen. The electrolytic hydrogen generators do not produce pressure so you will need a pump.
you can easily do all of what I have seen on your videos freehand! so I disagree that you need a lathe. I realize that it makes the process easier, and is perfect for amateurs in regards to glass working, but any lamp worker with even medium skills should be able to do all of the things you show freehand or on bench rollers! and though hand torches are a game changer for the welds, most of the work can be done on a bench torch. its just a matter of how you work. great vids and awesome stuff!
Oh Wow, I'm glad have something constructive to occupy your time. I'd to imagine whadya do if ya were bored. Oh the mischief ya musta been in as a kid! Is it just me or can anyone else "hear" the color of that shirt? Or am I trippin? Without knowing ya, I hope that ya can appreciate my humor! I seriously appreciate how rare that this craft is practiced. Question? Obviously tubes went away before social conscienceness made practical recycling of mass consumables...
I have to completely disagree with you about it being nearly impossible to do the things you are doing with glass without a lathe! thought I agree it makes it much more doable for an amateur, the things you are doing with glass are all easily accomplished freehand or on bench rollers! I will do a video demoing a tube if you would like all free hand. I am not saying doing it on a lathe is bad, and since you have one go for it, but this can all be easily done without it for a skilled lamp worker.

@@fisherteladi1837 It is made from unique parts that were gotten from a junk yard. No way to duplicate it. Sorry.
@@glasslinger I love that lathe also. I am going to build one and I will do my best to video it.
That is just... AWESOME! Seems like you can build a tube when you need it. Guys who restore old TV's and radios could become your clients.
Amazing... Respect... I love it when people are truly are hands on and know what they're talking about...

Could be useful for coming up with better tubes than there were. Modern math & computer work can make short order of electrode sizes.

Very interesting video.
I love the video you produce, very interesting, did you work in the electronics/electrical industry or are you self taught.
Hi, first of all thanks for the knowledge you show with us, if you could show how's your lathe made, what parts are used, it would be a treasure!
Unfortunately, the parts were all from ebay, which means they are not commonly available. It would be impossible to make it now since the parts are not available.
I have two exactly the same diffusionpumps but i havent got time to figure out how to connect the outlet since its just a straight tube and not the usual vacuum fittings. It seems as you use some similar principle as when you connect a tube to the system with that nut and o-ring, correct?
Hi Ron, it is possible to make a vacuum triode tube without all the special devices you have? Only with simple tools.
