While disappointing, It's not as bad as I have experienced for a new supplier doing something that stretches their experience. I've found that suppliers need to ramp up their methods until they meet your quality requirements and recognize the defects themselves. Generally, a long-term supplier will give you a redo discount to cover materials and such (negotiate) receiving the initial batch. You can sit down with them and the line workers to discuss the flaws.
I'm so keen with these new videos! The uncoated tube case rims look like a major oversight from the paint shop, they do really need more detailed instruction, also showing them the whole clock as finished would maybe help them understand the job better.
The holder for the round part is not ideal in my opinion. It's hard for the painter to turn the part reliably. This can explain some of the inconsistencies. It would help to out a tube over the holder and weld it to one side of the bend wire. it will be much easier to turn. It would also be a good idea to go to the people who've done the first batch and ask them: - What was their most common problem. - How the work holding could be made better. - did they see ways to make the hole process easier for them. (placing the final product, getting a new product, cleaning, applying the coating, etc.) There are often problems you don't see and people are working around it instead of "complaining". Do the questioning after the first batch then after 10 and then after 100 to see if there are problems that only appear in "mass production". Do that regardless of the quality of the final product. People working around problems can make things awkward, annoying, complicated and inconstant.
Too bad about the Cerakote. I'm wondering if regular powdercoat would be more cost effective. There are hundreds of colour choices, and it's a tough and durable coating for indoor use.
Problem is it will be glossy, which the ceracoat is not. But first batch generally has a high defect rate till the producer optimises the line and layout, and the people doing it get experience as to the desired result. I think the second batch will be better, especially as you see the defects were all on the one side of the box, saying they were first units. At least local supplier easy to show them the defects, and a good one, so they know what is required. Would say that a jig that holds the parts all in a line, and spins them as well, will be better. A simple jig with hooks to hang those holders, and a set of pulleys and O ring drive belts, with a small DC speed controlled motor ,will work well there. Long steel U channel, with small bushings to hold the rod, and using sintered bronze as a bush, so no oil to run down after the initial soak, will work well. Small stamped steel pulley block, with the long O ring snaking around them, then returning via an idler pulley to the motor, will be easy to make, as Dalibor already has a lathe and mill, which makes the frame and bushes easy to make, and then pulleys and rods slide down, with a simple thread at the end, and hook eyes to hold the parts. All metal so no static issues, and say 15 units at a time with a single run of the coating gun.
@@SeanBZA I really like the Cerakote but I was a bit alarmed when Dalibor said how much the coating costs per part. I have powdercoat in all different gloss levels from flat to full gloss and there are dozens of different textures too. You can also re-work it without having to strip it and sandblast again. It's not my project though and I am sure Dalibor and his suppliers will do a fine job.
You are an impressive young man. I’ve been watching you from the start and I’m happy to see you growing and doing well. In another life, I’d love to work with you.
You are doing a remarkable job that requires efforts to solve an incredible number of challenges and obstacles, definitively proving that you are a person far above average, capable of great feats through your extraordinary will and stubbornness! I send you all my congratulations and respect. You are under the gaze and help of God, that is certain. Stay close to your personal internal Father, pray to him, talk to him, love him. ;) Never forget this sublime Sufi word: "I have sought the beloved everywhere throughout the world, and he was waiting for me in my own house." Good luck, may God bless you, hero of modern times.
vaguely related... but not... theres a million and one videos on CRTs and cathode ray emission. but i cannot find any videos with a demonstration of "positive rays" or "anode emissions". physical demonstrations rather than animations. it requires a slightly modified CRT to produce... perforated cathode with a bit of room behind it for deflecting coils/electrodes. it takes place BEHIND the cathode... one of the fundamentals of electron charge, relates back to JJ thomson, and its just one of those subjects that seems to be overlooked in this modern age... which is a shame... not many people are equipped to make such things... hint hint :)
@@EdwinSteiner your point being? "positive rays". the stripped ion of gases such as hydrogen that flows the other way and deflects in magnetic and electric fields to demonstrate a positive charge, and large mass...
@@paradiselost9946 You answered your question yourself: "Gases"! CRTs are *vacuum* tubes and the heated metal in the cathode boils of electrons, not positive ions. Gases are purposefully removed from the CRT in order to allow the beam to move freely through the interior. So you don't have moving positive charges in a vacuum tube. I'm not sure what you are looking for. Experiments with gas-filled tubes?
Very excited to see the new tubes. Thanks so much for bringing them back.

Absolutely like the series. And jigs. and fixtures ❤
My 4 tube clock is still going strong and we are so glad you are making them!
looking good Dalibor....

Do you use a Visual Basic script to generate those schedules?

Electrons are negatively charged. That's hard to change, to put it mildly.
