brass is not cheep!

As 'an engineer' , you should be using mm/sec, not mm/min…

This level of technical elegance is oft overlooked in modern times and is absolutely necessary for the next stages in computing. Thank you for sharing this extremely interesting and scientifically _sound_ knowledge!

I love your videos. However, and in my opinion, I believe that they can be improved if you would able to make a more clear context on what you are building. This is because, honestly, in the point of view of machining, this is not a big deal. But, as an RF device, there are a lot going on and I can see that this is your area of expertise. Be able to pick a little of your knowledge would be the most important part on your videos. That is, I would like to see your videos and learn a little about the microwave project you are involved. For example, where this device will be connected, how it was sized, why the waveguide length must be adjusted, was there some EM simulation,.... I have so many questions :).

Going so well had my interest then came the music so 👎 and exit stage right

Sorry to heae about your loss mate. Jokes about ya chip collection and I will have to buy you frothie, nice cold beer or heaven forbid a cup of tee...not sure how to spell tea, I am allegic, makes me vomit...but beer is what helped me fet through my divorce..

Ohhh this video much easier to understand for me 😂❤ love your setup and its impressive how you install all these yourself i assume? And Amy makes me giggle

Hehehe it's a bit like learning history too ☺️

Skip the disclaimers for the math bits! There's no need to excuse a peek under the hood on a tinkering channel. Cheers!

Such a relief to see someone actually does it the proper way and uses spot drills for pilot holes instead of using center drills!

Wow, a lot of new interesting RF stuff! Thx for sharing!

You are a proper UA-camr, but I feel like that's insult..

How to over explain a tin can phone we used as kids

18:20

I worked on SAR imaging and database updates from 1991-2001 for the state dep. with electrically commutated phased array antennas. Would love to have these lenses today. In 1995 we started looking for truck launched icbms in russia based on a known image sample of a real icbm truck that partook in a test launch. In 1996 the state dep dude arrived at my desk and pulled me to our secure conference room - showed me this picture from a Kh-11 optical sat of what looked like a truck launched icbm to me, and then said our computer didn't correctly identify this one. Rather than look at the billions of calculations I just had the computer show me what wasn't consistent with a known icbm, well - the missile rode 75mm too high on the truck chassis. switching frequencies to skin effect penetration, we found the inside hollow - no fuel. I was a young prof eng rf/uW at the time with quite an attitude and a loud voice when I yelled at the state dep guy "My computer is perfect - your stupid humans fell for a decoy on your kh-11 kodak brownie moment sat - deorbit those damn things and learn to use SAR. See this structure - watch as I shoot through the roof and take a look inside - your kodak brownie kh-11 can't do this - but there's a truck with a real icbm inside. You'll miss that one optically. " He left tail between his legs. That system was meant to fight a war with russia and make sure the right people die. My computer has now killed over 1/2 million dead russians. It sends the firing solutions to the M777 digital howitzer and center punches tanks then pops their turret off - 1/2m cep on a 155mm gun. With operators who can't read the manual. Turn wheels until they glow green and pull cord. simple. We figured once russia saw our power they'd pull out, but no they kept sending tanks and we kept blowing them up. I will say in 1991 it didn't look like war with russia would ever happen, but today, I'm glad we made the investment in SAR tech back then.

I've got 3 vernier calipers. A moore and wright. A fractional moore and wright and a mitutoyo. Not only don't they read the same, the difference is not linear. At different diameters the caliper reading the highest could change with no logical pattern to it.

As an aside, re the relative losses of bare -v- silver plated copper. Circa 1950s, a couple of Engineers at the Australian Postmaster General's Dept Lab were investigating losses in a HF PA stage anode tank circuit. The particular unit they were working with used bare copper coils, so they made up some really nice silver plated replicas & installed them, expecting to get a measurable improvement in losses. Anti-intuitively, the losses increased! This led them down a far more interesting "rabbit hole" than they had anticipated. They discovered that in earlier times, the purity of copper available was not as high as that available in the 1950s, so silver plating using plating solution as then constituted gave a reduction in losses.Two things had since conspired to reverse that situation:- (1) the purity, & hence resistivity of commercially available copper tubing had improved considerably & (2) Commercial silver plating solution makeup had been "improved" from the point of view of the primary decorative use of such plating with the addition of impurities which improved the lustre & durability of the plating, whilst unfortunately increasing its resistivity. It then became imperative to specify the plating as for electronics work, attracting a higher cost premium.

Thank You For Realising This Video On My Birthday :D 21.March

I find you channel.. today ! Finally.. after years stumbeling around .. I got one thing to ask, because your brain look very smart and also your fingers look like they do, what you tell them to do..: Did you ever thought about a tool to cut parabolic things on a lathe without cnc ? If not, please consider to do so. I am the one who give you the first thumb-up or two.. (thats all ??!?!? sure :-) ) Such a tool didnt exist till now - as far as i know. It would be a great thing to have for cutting light reflector or some type of gears or metal precisely cut to realy fit the home made scrap bin. I tried to do it, but failed, because it had to be small (and also cheap) to cut parabol inside and so it is not stiff and also it cant be to big for home used lathe. And i also dont know if it would be that precise to make it usefull or even if it will work anyway. May be you like that challange or someone who read this.

Glad to see my lathe and work area isn't the only one that looks like that.

Missed you bud! Glad you're back and doing well.

Glad to see you back sir. I've recently learned 2 and 3 axis cnc milling. I don't make anything nearly as cool as you do, but it's so rewarding to bring a project from a drawing to a finished product. Doing it on a fancy new machine must feel quite good.

Well, you have some really nice results here.

Oh, Man, have I just found a channel featuring the two hobbies where I have almost no clue what I’m doing? Looks like it. But I only have a Taig lathe (plus a very clapped-out ML7), and a KX3 plus a collection of Morse keys and paddles. I liked the video,cand you have a new subscriber.. 73, g0nmd

anyone else try to wipe the schmutz off the DRO at 26:55? no? just me…

That is a HUGE gear. I can't believe watchmaker youtube sent me here

0:29 The shrinking of the small nylon gear leads to increase of the stress around the circumference. It shrinks on the axle, but because of the non shrinking of the axle, the stress in the circumference increases, which leads to the snipping of the gear . This effect is the more, the bigger the inner axle is in relation to the gear. It´s a common design flaw.

They should look at the videos of Pakistan shops. The chips are 5" high by 6* behind the machines on dirt floors . Flip flops long dresses no eye protection. They dont care go tell them you clean fetish.

Miss Amy did not read your Community posts?

Man, I'm happy I've found your channel again! Subscribed this time! 😃 But yeah, that would be great for so many tools! Even those made out of wood, it would increase the precision a LOT! Anyway, stay safe there with your family! 🖖😊

Some nice results there. I tried and failed with that brilliance laser ink. I baulked at the price of the minuscule spray can and bought the powder instead. Despite trying multiple speed and power settings with a 50W CO2 and a 22W diode laser, the black marks just rubbed off. Anodised aluminium and the 50W CO2 works best for me.

The endmills in chucks debate usually lacks the nuance of what you're doing with it; straight down into aluminum is much different to cutting sideways, in tougher materials or both.

Out of curiosity, did you type the subtitles or are they automatically generated? Korloy is in there - correctly - and I'd be impressed if the automatic caption system recognized that somewhat niche term.

Interesting. I was considering getting a fiber laser to do this sort of thing, they are a bit spendy though.

Nice. I'd like to get one of these sometime, if only for doodling on biscuits and toast.

Superb Neil. I just noticed your CEE mug. The other machining channel I love. 😊

Might it help to: (two SEPARATE suggestions): 1) Print a pointer in the diametrically opposite direction too (on the moving inner circle), perhaps with a different icon. This helps to eliminate error coming from axial misalignment 2) Print a vernier scale on the inner ring *simultaneously* while printing the outer ring. Any errors (from quirks in the engraver) shall be identical on the tro parts, and shall tend to cancel out. Obviously, two vernier-scales too one at the "pointer" and one at the 6 o'clock.

The legend is back❤❤❤❤

Maestro of Microwaves 👋; Have you tried doing a vernier scale? A 10:1 is useful, i guess that a 60:1 would require very fine "ticks", and a magnifier...I guess, with the precision you seem to have, you could put the ticks with a hairline at the base, for all of them, and the "normal" ticks about 2 mm offset? As one says: "it's just a thought.."

Rite Microwave Dude, I had to watch a few times to understand what you were trying to do. If you make another circle in the center of the big circle then when you create the array you tick the box "use last selected object position as center" it will then rotate the lines around the center of the circle in the center of your big circle. Hope that makes sense! TFS, GB :)

Nice light work! xD

I must say, I consider myself a very stupid individual. And I have no idea of the technical words you use. I'm a bit lost to be honest. But I did enjoy watching this video very much. Thank you for taking the time to make it!

👍👍😎👍👍

I ain't bovvered!

Good to see you back, hope you've shaken the dreaded lurgy!

I'm mot going to have hysterics over counterboring with an end mill, since I'm the sort of Philistine who occasionally does it with a Pilot-Point drill bit. 😜

Finding it funny, even when you use the French system of measurements, it's still SAE just in decimal wrong

Love it

Nibbler Power! 😂 #Futurama

I have 2 usb 3 cables and it only has 4.4-4.6v even some powered USB hubs don't even like dealing with the lower voltage or attenuation.
