you made a beautiful azimuth ring with a mark for each degree but the pointer line doesn't do it justice. the pointer should be fine enough to split each degree. yes, I know it doesn't matter but its principal! amazing work. its easy for me to poke fun from this keyboard.
The original plan was to make a stainless pointer and engrave a 0.2 degree incremental Vernier scale and magnifier. That will be a future upgrade, but it needs a bit of care about dealing with grit, water and oil. Soon as my CNC machine is up and running, I'll be able to do that much more easily. Also I need to do a detailed calibration of the scale to make sure there aren't any weird inconsistencies. ALso the pointer needs to be flush with the ring. I did consider using an engraved and filled 0.1 mm line on the underside of a clear plate, and I might just try that. In reality though, those dishes have a 3 degree beamwidth at X band, so any more than "about a degree" precision is a bit pointless. The next iteration is for much higher frequencies, and will have a remotely operated geared adjustment for fine tuning once locked. That will be for dishes 250 mm diameter at 134 GHz, which need a much more precise pointing. This is great for testing thermal noise from the Sun in the 5 to 30 GHz range or my outdoor antenna range when I'm characterising antenna feeds
Lasers used to bleach dyes definitely make sense as it is the problem that most dye lasers have when pumped at high powers. Cool to see this used for a useful purpose.
I've surprised myself about what it can be used for. Simple things like laying out a sheet metal cutting/banding pattern to make a standard-gain horn, or a conical horn are just so easy now
I'm on a steep learning curve with my new SYIL X5 CNC, making the first parts now, so hope to get a few vids out soon showing the staggering depths of my incompetence and the fumbling inadequacies of my Fusion360 CAM work. Should be hilarious.
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. 😜
Ah, the endless and unfruitful task faced by Geometers since Time Immemorial... Which is September 3rd 1189 in UK law. Richard the Lionheart's reign. So actually very recent in geometry.
Any reason you went for rolling element bearings rather than bushes and thrust washers from a bearing plastic (or my favourites, teflon sintered bushes)? Hardly a high speed rotation, and not even full rotations at that...
Purely because it was originally going to be an an offcuts build, made from odds and sods. The bearings were in a box of donated bits, I was going to use a rusty old 3/4 inch threaded bar from a field gate hinge as the shaft, and a bit of aluminium plate with odd holes in that I recovered from an old amplifier, but it turned out to be too narrow, so that ended up as the polishing mandrel. For a production version, I'd use bushes for certain. Maybe stainless on UHMWPE, or indeed some fancy sintered bushes and thrust washers
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.
I generated them in Davinci Resolve, then did a manual edit to remove some awkward line splits. It generated Corloy and Hawley instead of Korloy and Horley, and made a mess of a few other phrases, but it's remarkably good compared with the YT cloud service
@@MachiningandMicrowavesHigh performance and PL259 was something I didn't think I'd ever hear in the same breath. (Unless talking to the HF wallahs... But we don't talk to them!)
@@gonzo_the_great1675 I tend to think of radio from VLF to UHF as slowly-varying DC that you can watch on a basic oscilloscope. Shielded banana plugs like the PL-259 are pretty decent at DC apart from the weird connection of the shield. Now if they had a consistent three-point tapered connection and a proper nut that you could torque up to get a really nice gas-tight non-rocking connection, that might be quite decent, but a DIN connector has that completely solved. Still might be fun to try though
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.
Also it makes a difference if the chuck has a drawbar and if there's a Jacobs taper or something solid. I wouldn't try it with a 3/4" end mill in a drill press with a Morse taper and no drawbar. Although it might make for a decent video
Yes, this little project was so I could try multiple different processes to make marked metal rings. That is for a sponsored video I'm making for Creality about their desktop lasers. The rings all use the same design, but show different techniques and materials.
That power nibbler is just BEGGING for some googly eyes and a set of faux upper teeth!!
You, Sir have won the internet for today. Superb suggestion and I shall be implementing this major technical upgrade forthwith!
@@MachiningandMicrowaves YAY! I await the results on tenterhooks, sir, TENTERHOOKS!

Machining purists should be baited, not discouraged. Feeds the algorithm.

Good to see you back, hope you've shaken the dreaded lurgy!
Glad to see you (and Aimee) back!
Most weird! I was thinking that I hadn’t seen a video from you last night. No idea why but here you are with a new one. Cheers!
its like poetry in motion 👍 I'm envious of your tools and craftsmanship 👊
Amazing engineering a joy to watch. I recently picked up a surveyors tripod for a portable stand for a HF vertical
I bought a batch of five brand new ones for £21 each. Impressive value
I can recommend the Hemingway knurler kit based on a Marlco design. I love mine.
You're really getting mileage out of that laser! Looking forward to seeing the new toy

Glad to see one of your videos again sir, very interesting project
This is so cool!
Missed you bud! Glad you're back and doing well.
I'm on a steep learning curve with my new SYIL X5 CNC, making the first parts now, so hope to get a few vids out soon showing the staggering depths of my incompetence and the fumbling inadequacies of my Fusion360 CAM work. Should be hilarious.
I learned on BobCAD, it was quite the learning curve for me as well.
The brass reminds me of Christmas.
Oh no, I was 8 minutes in before I realized I might want to be wearing eye protection while watching this video.
Oooh! I should have put an AvE content warning on it. "Engage Safety Squints!"
wonderful work ! 👍
Love it

Well played Sir!
I thought Amy had been laid to rest under the patio, then she appeared 12 minutes in.
Nice work, er, circling the square? That doesn't sound right somehow!🤣

@@MachiningandMicrowavesAh! The famous "I think I have something that will do over here" build.
Been there too.

I would love to see you make type N connectors.
N-types are certainly fun to make,, but a bigger challenge is making a high performance PL-259! I'll have a think!

What's the purpose of the multiple scale rings? Just to try out different materials, or are the scales actually different somehow?

Miss Amy did not read your Community posts?
I have firewalls. Have to keep some things secret!
Finding it funny, even when you use the French system of measurements, it's still SAE just in decimal wrong
What happened to your lovely Assistant? Is she on spring-break or prepping for the AI-uprising?😊
Someone has been skipping past Aimee's "helpful interventions"! There are several brief apparitions during the video, honest Guv!
👍👍😎👍👍
Can you sell me one?
It needs a lot of development before there will be any for sale. i need to get the braking/lock mechanism sorted out for example
Nibbler Power! 😂 #Futurama
