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.
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.
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.
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!
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.
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!
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
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.
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.
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
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.
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 like how you and another RU-vidr jdflyback show the whole glass blowing and working process. It’s amazing to watch the heating, manipulation and annealing of the glass.
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.
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.
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
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.
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.
