You make it look so easy, but I know it takes a decent amount of skill to be able to do something like that. You never know when we might have to fall back on an old technology to move forward again. 👍
Great to see you making tubes again Ron... Really enjoyed this one. Let's hope the tube lasts without the getter.. Looking forwards to the next video... using it in a 1912 style radio sounds great fun... Thanks for sharing...
Ron, how I wish you could have been my grandfather or great-grandfather when I was young. I like to think I'd have been round your place every weekend I could, doing something *awesome*! I don't know if you have family, but if you do, I sincerely hope they value you very highly and preserve your achievements long into the future. You're an absolute diamond.
Crumbs, I'm in awe. Back in the day, working with fibre optics, I couldn't successfully join a quartz tube to a same diameter feed tube, despite months of trying.
Hi Ron. well that's absolutely amazing there can not be many people left in this world that could still build a tube /valve from scratch. Now I know why you have the handle glass slinger.
Ron nice to see you back with another tube. Sure did turn out nice. I'm thinking in another 20 years no one will know what that tube really is. What a shame to loose all that history. Can't wait for the next video.
Always love seeing you videos on making tubes. Have an urge to try myself but getting all the gear to do it makes watching you so much easier. Glad to see you back doing this stuff.
A great video Ron.. thanks for sharing. I reckon there no more than 4 ppl still naking tubes, you, Dalibor Farny and around 2 others.. definately a dying skill.
Hi Ron your tech friend Dave here from up North I enjoyed your amazing video you're amazing talent can't wait for you to work on that radio been doing a lot of radio work for people myself hope you have a good summer stay in good health you're a good friend Dave may God bless and keep you safe always
Don't know if you have ever tried this with epoxy. Squeeze it into a little plastic parts baggie, zip it up and mix it. Smush it down into one corner and cut the tip off. You can now use it just as if you are decorating a cake. Great video, thanks!
When you scraped and put leads on the last two wires from the tube it had me on the edge biting my tongue fearing the the bits that evil types like to see
Mate you have me wanting to buy some machinery and start doing stuff. I really appreciate your taking time to show all that want to learn, know and do things that would’ve really been impossible before your teaching’s. 😊😊😊😊😊😊😊😊😊😊 10 out of 10.
I really admire what you do and although I have no clue, this really makes me want to try and understand how a filament could energise a plate and grid and how it’s possible one wants to oppose the other. This fascinates me a lot.
Basically, the filament emits electrons - which have a negative charge. A positive voltage is applied to the plate. The grid is supplied with a zero or negative voltage. With no negative voltage on the grid, the electrons flow from the filament to the plate. If a negative voltage is applied to the grid, it impedes the flow of electrons from the filament. If the grid voltage is high enough, it completely blocks the electron flow. There should be a good description of triodes on Wikipedia.
If civilization collapses, we'll need to know how to DIY the tools to play and amplify optical audio tracks on film reels. These are the easiest to decode among movie formats. Recreating tech like magnetic tape or laser discs players, to re-inventing modern computers would be almost impossible in a post-civilization world, meaning we'd lose a ton of knowledge we've gathered over thousands of years. That's why it's crucial to record info on mediums we can still decode and use after the collapse of civilization. Being able to make and use amplifiers and other tools for optical sound decoding could be key to keeping our knowledge alive! thank you for this video, I’ll print it on film and keep in a bunkered safe!
You always deliver beautiful gifts of knowledge and your skills, craftmanship and fine eye clearly demonstrate that you have learned and can share every gift you have been given. Getter or no, simply fantastic.
The machinist in me wanted a better look at the lathe your using. Those are probably not easy to find these days. Maybe they even used them to make Christmas ornaments at some point in history. I'm not sure where soda glass got it's name but I can still remember watching a carnival guy working on pop bottles with a torch. The carnie guy's prizes were two foot tall melted soda bottles filled with colored water and capped. Empty pop bottles were worth 2 cents apiece in the late 60's and early 70's. He had Coke, Pepsi, 7-Up, Bubble Up and the other common flavors from that era. He grabbed the top of the bottles with a pliers and heated the neck with his torch. When the glass got soft he pulled and bent the bottle necks into wavy slender shapes and let them cool. I don't remember him annealing the glass afterwards but he never planned on these "prizes" to last that long any way. Once he had enough made to fill his booth with prizes he filled them all with water. He then took ordinary food coloring and put a drop in the top of each bottle. Sometimes he matched the flavors such as orange for Orange Crush but he also just made up pretty colors like blue water in a Pepsi bottle. 60 years later I occasionally stumble into an antique shop and find one of these carnie bottles that has survived. Like you he managed to turn a two cent piece of glass into a prize that may last far longer than the artist.
Back in the mid 70's, my aunt had a bunch of these in her room. She was a teen in the late 60's and I always wondered where she got these. She also had a bunch of small vials that had liquid in them. They had cork stoppers and she'd always yell at me for messing with them. She'd hand-pick out the ones that were empty to let play with them.
Soda glass refers to the addition of soda lime to the raw silicon dioxide before the glass is first formed; it lowers the melting point of the glass considerably, but it also makes it more prone to thermal shock.
Hello Sir, Great video with respect to making of such tube. It's a very sensitive and crucial work and it really requires adequate knowledge and skill. It's an tutorial video for new generation people. Thank You
GREEEAT VIDEO! Thank you a lot for sharing it and telling us the values of voltage and current you get. What do you think the current would be if you use regular tungsten? Half? And thinking about it, a video or at least the schematics of your measuring triodes device would be great too
Actually, the function of the tube would be the same with a plain tungsten filament! The big difference would be the life of the filament, which would be typically 20-30 hours, while the life of the thoriated filament will be hundreds of hours! No schematics available right now on the transconductance tester.
The very first video I did on youtube was a version of this. This was when they limited videos to 15 minutes so I had to make 4 parts. Not very practical. Also that video used a cheap camera. (horrible!) So I figured I would remake it in one video with better editing.
I hope you'll understand what I mean here.. When joining two pieces of glass, does the molten glass "wet out" like metal does when welding or soldering?
Joining glass is like welding with the two pieces literally melting together. If the two pieces are not hot enough the joint is simply "stuck" together and will shear apart at the joint at the slightest stress.
Amazing, I guess I’m not going to do this with a propane torch. I think it’s safe to say that’s a lost art. I’d like to see a vintage film of how these were mass produced back in the day
You could use a few side flames to help stop the glass cracking, how do you stress relief the finished envelope. Made a few glass things and put them in a kilm and then let cool slowly.
Just out of curiosity, why did you connect the two plates and two grids in parallel? With them separate, you have a dual triode. Was it just to match the design of the early Audions?
I would assume yes, in faithfulness to the original but I'm just guessing. Isn't there a way that configuration can be done or undone outside of the valve construction, like I mean, even as he's shown it in this video it doesn't have to be a permanent decision does it?
@@thomasrussell4674 The way it was constructed, you cannot change it. It can only be used as a single diode or triode. If all four leads (2 plates and 2 grids) at the top been brought out separately, then it could be changed with external connections.

Fabulous Ron, your laying down tutorials that will maintain tube craft into the future, extremely valuable
Its folks like this what got us to the moon.
they already has transistors by then.
@@tripplefives1402... ok. Then what?
Great to see you back! I love your videos; have learned much from you. Keep creating!
Its great to see you making a tube again. Thanks. It works a treat too. Looking forward to seeing it in use.
It's always so awesome watching you make valves. Can't wait to see it in use.
Lovely to see you again. I so enjoy watching you work the magic.

What a great video Ron! I found the glass work mesmerizing.
Being handmade, it would be safe to say that no 2 tubes performed the same.
Fabulous Ron! Thank you for sharing and teaching! ❤

Wow! I had no idea that you could DIY vacuum tubes. Nice work!
good to see u back on the lath blowing glass ect , though was no more with the cost factor ect these days
Congratulations, that is a tricky bit of work to accomplish with out a misshap.
Great to see a new video where you make tubes

Very cool.. will be fun to see the tube working in a radio 👍
Great instructional vid. we will be waiting for you're next installment.. Take care sugar stay well..
No matter how many times I see it, it's nice to see glass being melted.
I do use tubes. This reminds me of building a ship in a bottle, which I haven't done. Amazing how bits of metal and glass work together. Love it.
Nifty AF ! Such a rare(virtually extinct) art AND mad skill. 👍
Dear Ron, I've seen many videos from you and allways enjoy them. Lucky to see you're doing well. Missing Supervixor Kitty...

Looking forward to seeing you making the 20’s radio 👍🏼
Nice job, Ron! (as always - despite the slight lapses of memory...😄 )

Thank You
O my god! Welcome back my friend!!! i hope your still in great health!!!! You are truly an artiest!!
Straight from De Forest Primeval!
Always enjoying your tube experiments!
And that's a first... Ron using actual soldering iron instead of gun!
Pure art!
high craftsmanship!
Excellent!
Hurra!!! Tube making is back!

Thanks, the subtitles were informative and amusing!
What fuel gas are you using Ron? The flame looks like oxy-propane or oxy-butane, would I be correct?
Close. I have a compressor that I use to pump up the pressure of natural gas from the house outlet. Very cheap!
That was absolutely amazing to watch
I feel I have seen this before. But heck, I'll watch it again.
I don't remember having seen this exact one

You might be able to do so, if you used Pyrex instead of soda glass. But you would need multiple torches with different flame tips.
These are my favourite videos that you make
You could use a few side flames to help stop the glass cracking, how do you stress relief the finished envelope.
Made a few glass things and put them in a kilm and then let cool slowly.
Ron, what kind of non-conductive J-B Weld did you use to secure the two wires at the top of the tube?
it's the standard hardware store epoxy called JB Quick, the 5 minute stuff. It has no conduction at voltages below 500 volts.
Excellent work. Why don't you weld the plate? Not a criticism, just wondering why. A great video
The original used pinched wires. Of course it would be easiest to weld it.
@@glasslingerThank you for the reply. I hope you're proud of your work. It's outstanding. I look forward to the next video.
Some of the best content hands down
I love these tube making videos
How much in gas did it cost to make the tube. Excellent video and looking forward to the next part. Thankyou for sharing your knowledge.
Gas is cheap here in the USA. I would say about 50 cents worth.
@glasslinger thankyou for your reply yes that sounds very reasonable.
Fireproof paper = asbestos? Looks like an asbestos sheet to me XD
Yes, it sure is!
Just discovered your channel. What is the material you made the plates from & how thick is it?
This is nickel sheet removed from an old TV tube. It is .004 inch thick.
@@glasslinger I have much to glean from your channel. Thanks for your time and effort.

If all four leads (2 plates and 2 grids) at the top been brought out separately, then it could be changed with external connections.
The risk of leaks in the seal wires increases greatly as the number of feedthroughs increases. Adding two more wires would not be worth the risk!
Good work and result :)
