always learning something from tuning in - keep inspiring & safe travels

I was struck by how small and compact the gyro unit was compared to what I was trained on. My experience is with US Navy systems dating back to the 60's and 70's. I was always somewhat amazed at how a unit (Sperry Mk 19) could provide such precise heading info (plus pitch/roll info for weapons systems) while being controlled from a separate cabinet full of banks of vacuum tubes. Total time from startup to accurate was about 24 hours. The ship I was on had a secondary unit (Sperry Mk 23) which was all solid-state, but it was actually not as accurate as the dinosaur bolted to the middle of my shop floor. Pitch and roll accuracy forced the gyros to be located centerline and on the 3rd deck...about 10 feet below our laden waterline. This means that every gyro indicator on board was actually a repeater fed from my shop...about 10 total. If curious, look up USS Kansas City (AOR-3) sometime. You haven't transferred fuel and cargo until you transfer it to another ship....at 17 knots. Needless to say, accuracy of ship's control and navigation equipment was a BIG thing.

I will always look forward on how you put up your words and precisely explain or narrate it for your audience. Thank you sir

Great of you to set a timer for when the sponsor is over. I appreciate that.

These videos are a window into another life that I could have chosen and been just as happy as I am with the life I chose. So glad you share it with us.

Thank you for adding a timer to the sponsered segment

Gladly i'm a teacher. However, i'm moved with your vid bro. Keep it up. Pray you safe. With love and respect from MALAYSIA.

So happy everytime I see you uploaded something new. Loving it.

"so, lets check it out" !! endless curiosity is satiated in this type of production. thank you Chief.

Every single one of your videos is not only informative and fascinating, but also kind of zen to watch. You have such a calm voice, perfect for narration. I adore your channel.

Absolutely fascinating and so clear. Thank you Chief

Thank for the video Chief Makoi ! Looking at the technician installing the repaired unit reminded me of my days installing garbage disposals (haha). Surprisingly complicated precision instrument. Very interesting stuff.

This is super content. Your delivery style plus the filming and editing make it easy to watch. Thanks

What a piece of equipment! Some of the greatest most beautifully complex pieces of equipment come from maritime navigation. So cool.

Lesson taught and learned....thank you Chief.

I apologize if I missed you saying this, but I was left not understanding HOW a gyrocompass determined true north. Wikipedia says: - they find true north as determined by the axis of the Earth's rotation, which is different from, and navigationally more useful than, magnetic north, and - they are unaffected by ferromagnetic materials, such as in a ship's steel hull, which distort the magnetic field. So I assume that by "settling in," as you say, they are basically figuring out which way the world is rotating, and from that they derive compass directions. Really have been enjoying your videos since KZfaq surfaced you in my recommendations. Always informative, and occasionally, like the night passage through Istanbul and the three bridges, beautiful.

Chief, My best love, wishes and regards to you, your family and the whole crew. May God bless all.

ı am the third officer :) whşle ı was searching detail of gyro working principle ı found this video. Video is so benefital. thank u so much sir :)

Very detailed takes me back to my master helm days thanks chief

Great video! In the movie Apollo 13, you hear them talk about "gimbal lock"; it means their ship has pointed in a direction that the gyros couldn't 'reach', and they are no longer accurate because they've tilted to an unrecoverable/unmeasurable angle and will require a realignment with 2 stars, to work again. The danger angles were shown as big, red dots on their black/white gauges, to tell the astronauts, "never point the ship in this direction or else you'll gimbal lock". Fascinating to see how they work, thanks Chief!

Excellent! Have been interested in the workings of the gyrocompass since my Navy days. Thanks!

Fantastic content! I came here by accident. After creating a gyro from LEGO to demonstrate the effects of a high speed revving mass (yes that really works), I decided to look up a bit more about gyros and came across this channel. Even though I’m a typical landlubber, loving sailing on a small open boat, I find myself watching many more of your movies.

Well you did it again, another super interesting video. I had never seen the insides of a Gyro so this was particularly interesting to me. You mentioned magnetic compasses which have been around for many many years...but as you said interference and specifically things such as magnetic anomalies can create havoc for a navigator. A friend of mine running his boat, which was a 50 footer found himself over 40 miles off course in a fog bank because someone had set a pair of metal pliers in a storage container beneath the compass (magnetic) housing...not only irritating but potentially dangerous. Thanks for the great video, so interesting and topical..Thanks Chief!!! All the best to you and yours...

As always fascinating , thank you for posting

Again, Something I knew existed but knew nothing about. thanks for the education (ya learn something every day) & though I'm getting on in years, I never want to stop learning. THANKS!

Hi Chief MAKOi : Thank you for de-mystifying the Gyro Compass for me . I note from the cartoon character of yourself you appear with a Pipe for smoking Tobacco. I smoked pipe for many years - the most satisfying and leisure inducing. I was a Ship's Electrician from 1958 to 1966 on various ships of The Burma Five Star Line in my younger days. I'm now 78 and Retired Electrical Inspector on a nice Australian Government pension (50 years in Australia). I no longer smoke due to my health reasons. Thank you for your videos. The Mercantile Marine has changed so drastically - it's not much fun anymore. Best wishes to you and your family and ship mates. May you all be safe. 06/12/2020 Perth W.A.

I found this video and all your others so interesting! Keep up the great content!

Very interesting. Thank you, Chief!

Love your videos bru. It appeared on my feed about two months ago, and I subscribed today. Keep up the good work, it's awesome

I remember when I was a deck cadet I learn that's equipment on the bridge and how to use and etc thank you of the learning of your videos..

Thank you for the lesson on this important piece of equipment! It is a great learning experience from you! Much Mabuhay and aloha, Chief! Salamat Po!

GOOD MORNING CHIEF. VERY INTERESTING. THANK YOU FOR GIVING US A GLIMPSE INTO A LIFE I CAN ONLY IMAGINE. EVEN THE SPONSOR WAS INTERESTING

A wonderful piece of kit - almost witchcraft how it finds North.... In case anyone wonders - if you try to turn a spinning wheel, it 'kicks' sideways. Only when the gyro is spinning parallel to the earth's spin is there no force during the 24h rotation of the Earth. Clever design (including the magic liquid we saw) converts any 'kick' into movement towards true parallel again. Thus the gyrocompass seeks and then shows true North. Love your film - if anything can show young people what life on a good ship can be like, it's your work. Please carry on making them, and safe passage to you and your crew....

Thanks Chief. ⚓️

Always interesting, always top quality!

Another great one ! Thanks for the education !

Great Video, love the direction you are taking. ;-)

Thanks Chief, Enjoyed

Brings back memories of my working life when a few years ago I would have been the one coming on board to fix it. Interesting to see the sphere opened up in the workshop, it looked like a Microtechnica to me.

As usual, great content .

Informative and interesting as always.... Thanks Chief ! Just bought a beginners sextant and am having fun learning how to use it :)

Salamat Chief M for this informatve detailed and amazing Video, may the seas be calm and your course always be true....!

Thank you!

Chief sayong mga videos lang talaga yung mga pinapanood ko na hindi ko makakalimutan yung mga aral grabe sobrang professional thumbs-up👍!!

Thank you sir! very timely, we are studying this at the moment

After waiting for many days finally its here

Excellent vlog as usual Chief stay safe 👊🇮🇪

Thank you for your hard work , great videos 👏🙏

Good information about the Gyrocompass and its maintenance🚢👍 ... a greeting and good navigation

FBS number 1. ❤️

Salamat sa lahat ng mga vlogs mo sir Chief Makoi, marami akong natutunan. more power po sir, God Bless you po ❤️

I've always wondered how that big compass thing on a ship worked! thanks for that

Basically same system as larger airplanes have. Military airplanes have always used gyros as main navigation device since GPS signal can be jammed or faked so GPS is usually used just to speed up the initial gyro align step.

Keep the videos coming there awesome!!

Interesting topic...Thank you Chief for sharing.

Thanks chief...

Afternoon. Great video of how your ship 🚢 functions 👍🏻

I've been motivated by your vids

in the early 1800s, there was a Royal Navy officer named Matthew Flinders. he was a first-class navigator. according to Bowditch in H.O. #9, there are two things that affect a compass. variation (natural things in and on the Earth) and deviation (objects around the compass on a ship). what Flinders came up with are iron bars placed near and around the compass that counteract the deviation. they were called "Flinders Bar".

This is fascinating. I never would've guessed a non-magnetic compass existed.

I like watching you chief you are very mature for your years your calm demeanor calms down my anxiety. If I had to work on one of these slave ships I think I would like to work under you. God bless you Chief good job.

Man, I never thought I would be interested in this kind of content. Now I look forward to each of your videos. Thanks for these little escapes, from a landlubber.

my favourite based sea channel

I do watch and a helmsman on bridge at night so I find this interesting. Very informative. Galing mo chief

Must admit that it would have been the last thing that I would learn about today. Thank You .... very interesting.

Cool. Use a gyrocompass and you don't have to worry about magnetic declination, space weather, or magnetic interference. At work we mostly used a magnetic compass because they can be build more robust than a gyro.

You make great videos.

Very interesting and educational! Keep it coming and safe travel.

I was just watching your around the world video, wondering what type of compass was used. I spent 5 years in the USNavy and was specialized in the gyro compass, although that was in the mid 70's the theory is still the same the equipment is quite different. I enjoy your videos, especially the ones onboard in the engineering spaces on the equipment. Keep up the good work on making these videos.

Love your videos! Stay safe my friend!

Interesting commentary... good one. I always watch your channel each video till end.👍

Fascinating

I enjoy your videos Chief! The gyro is also supplying a heading (course) to the electronic chart (ECDIS) and the ARPA radar for them to function properly. One of the most important instruments on the bridge. Cheers from a ship's pilot in Sweden.

Merry Christmas Chief to you and your family,and a safe and happy new year

Good video. That was very interesting. Thank you for posting it. See you next time.

I work in a company designing and manufacturing gyre compasses. Interesting to see them in action.

This video help me a lot for my Navigation subject, Midshipman Sumagaysay sir. Sir thank you sir.

Very interesting chief. Stay safe.

Aloha Chief, interesting as ever, fly safe and stay healthy

This was fascinating. Many moons ago, I was an avionics tech on high performance aircraft. But, I never got to see the insides of any of the gyroscopes that were part of the navigation systems. Different worlds....

My new Navy Ensign friend (graduated from PMA few months ago) should be familiar w/this by now...he's about to start his very first ship assignment in the Navy...

Thank you for a concise explanation of the operation of a gyro compass. I would have to, on many occasions deliver a compass adjuster to a ship so he could swing it. Boarding the adjuster from my launch was always during daylight, while the ship was at anchor. Always, the adjuster would complete his tasks at night, when the ship was steaming to sea. The ship was "outside" had no need of a pilot. I had to always ask the master of the ship to slow maximally to 6 knots, the ideal speed to safely embark the adjuster. One real fear I had was, that I would go to the wrong ship at night. No AIS for a 60 ft launch. The position was always given relative to the sea buoy. All ships look alike at night. Some times a master would temporarily light up the deck for me.

Apart from a panic over the gyro coming out of Houston in 1974 on the "Sugar Importer" we had few compass problems.

Keep it up, Chief.

Thankyou capt. I'm doing my module now but i watched this video I inspired and boost my confidence to finish my module 😂 Shout next vlog.♥️

It's like a giant pocket watch innards, way beyond my ability to comprehend. Or a lot of head scratching. Chief I hope you have Happy New Year.

Great vid thank you

Very informative.

Thank you, interesting video

As always another great video. Such a sophisticated piece of equipment but they still needed the empty water bottle for a container.

Grt Video Chief.learnt many a things

after the suez crisis. hehe, I stumbled across Makoi, hes a good bloke. anytime your on port, come for dinner.

Thanks

Reminds me of crossing the Indian Ocean back in 76. The Gyro went haywire, all of a sudden a noise filled the air. A sort of soft singing noise but it sent a shiver down the spine. At first we thought we’d drunk too much Ouzo or the Puffa Fish hadn’t been cooked properly. Before we knew it the ship started to rotate, at first slow then faster and faster. We were being sucked into a giant whirlpool ! All I remember after that was waking up on a beach on a tropical island. A young lady appeared and gestured me to follow. We arrived at a small village. They fed me and gave me a funny medicine. I spent what must have been weeks lying on a rough mat of palm leaves inside a wooden hut. Every day I got stronger and soon we were all building a raft to return me home. I set sail after saying goodbye, it was tough to leave especially because of the young lady who became my friend but I didn’t belong there. I will never forget my time on the island.

very useful video chief ,,,, thanks a lot :)

Nice Video Chief am learning alot ...

I really enjoy learning from you videos salamat po chief

are you grate seaferers sir give extr knowledge motivation video

Very cool.

Thank you very much sir for always sharing your knowledge we really appreciated SNAPPY SALUTE SIR C/E MAKOI
