I learned so much from your videos. 2 years ago I quit my boring job and invested my life savings on a 3 axis mill. Studied your videos and Lars Christensen as well. I became obsessed with machining, opened a small shop and doing well. Thanks for spreading the knowledge.
@@jmeleika1 were you able to design solutions for isolating stinks or maybe condensing the solid waste and separating and sterilizing water? Or trying to fit as many stalls in without stacking them vertically? Lol
As a retired programmer, I can appreciate what you have done. I started CNC programming in the early 80's using a very primitive Mastercam. It's all come such a long way.
Programming is pretty exciting stuff!! I started programming in the late 70's. Used a Friden Flex-o-writer to punch 8 track paper or mylar tape to run some old Acramatic 225 NC (not CNC) and Cincinnati Big Blue controls. Our first programming software was a product called NCApt, written by a guy named Dave Naylor in Seattle. Completely text based, NO graphics, just a Hewlett-Packard plotter. I've never used MasterCAM, but had a similar (sort of) product called SmartCam Freeform Machining. They disappeared for a while, but are back!
Great video! I did the installation of these machines. These are great guys that are making this product. Their passion is a lot like Titan's when it comes to machining. I'm so glad you guys were able to make this about this product and this company. American manufacturing is what it's all about. BOOM!!
JT, right! That’s exactly what I think every time I watch one of these Titans videos. I’m a button pushing machinist for a hydraulics manufacturer and our shop, while not filthy as far as dirt and chips go, is just cluttered. We and our machines are packed in like sardines. Not to mention some of our finished rods are 10 feet long and on carts all over the aisles. We can’t maneuver. I can only imagine how much clearer my head would be if I worked in such a clean and organized shop!

great machinist, but the “video producer” trying to pretend he invented the toroidal prop at his kitchen table is too much. There’s nothing wrong with refining a design and leading the way for its implementation, but don’t pretend to be the inventor.
Not to mention "NOBODY in the World Could Machine These Difficult Parts" is a absolute joke. So you're telling me that Nasa, SpaceX, Lockheed Martin couldn't do this.. The Tits of cnc machining more like it.
@@jasoncrandall they tried producing them in the 70’s but they were not commercially viable due to high production costs at the time (no cnc’s then). My friend found a patent for a toroidal prop from 1895, looks the same, a bit less pitch on the blades.
It would be great to see sharrow props hit a affordable price point, I've been impressed by the specs ever since hearing about them in boating mag. If they can bring the price down to only 2x conventional props its going to make a massive difference in uptake
@@WildcatWarrior15 I don’t think it would work. Metal printing just isn’t there yet. It’s not strong enough to make consumer grade props with. Props are under seriously extreme conditions from the point you start till you dock.
I just learnt about these props a few weeks ago. Now I see them being manufactured. I'm at the bottom of the world in New Zealand. I am encouraging my 2 teenage boys to get into CNC machining and 2 years ago brought a hobby CNC from them to learn on. I see it as a very bright future.
Yea I just saw a vid about these propellers too, I believe this design was first made at MIT. This propeller is supposed to be much more efficient than the regular ones, it’s also quieter and makes less cavitation.
This is a game changer for manufacturing. What a gorgeous end product. As a pilot and aerospace enthusiast I can confirm that this toroidal airfoil design is ideal for aviation as well.
This guy didn't invent them though. MIT did, and he's passing it off like he made it in his kitchen, while the video shows a photo from the MIT project.... quite disingenuous.
@@PBMS123 MIT only showed the models/math for the theoretical design for drones as far as I know. This dude took that new drone blade shape, and adapted/adjusted it for use in water, and teamed up with CNC machinists to actually make it.
@@kylem7708 except they didn't, that picture is the third iteration of drone propellers that they modelled and then manufactured and then tested you can go and see the MIT story and paper. They didn't just do the math they manufactured the propellers, and tested them.

Love it, guys! I'm retired now, but when I had my shop, I did very well taking the challenges that others were scared of. Just wish I would have had the technology you have access to nowadays. BOOM!!
Thank you for your videos. This is the most important reason why I was interested in improving my skills in machining. I work with a lot more simpler parts on a simple 3-axis machine, but when I see details like this ,my God, I want to learn how to produce it. Wonderful content!
At least you can write your own program do the set up and let it run but those 5-Axis with out CAM your are No where . 3 A-xis is the basic keep think about I can do it better.
This is what will make US manufacturing great again. Mass producing parts with CNC machines at large volumes in the US. If one machine can make a part from start to polish finish then all you need is real estate and a bunch of these machines.
Sadly as beautiful as the props look and the great Quality the fact only one person runs all the machines does not solve the many talented unemployed. People want to work on meaningful projects.
You know what’s funny, as a Northern Logistics truck driver, I believe we haul for Precision Mold and Machining. In fact I believe I’ve personally moved freight there a couple of times. Funny how small this world is. My personal Northern Logistics terminal is out of Clare MI. Perhaps one day we can haul for these guys too. I would love to hold one of these props in my hands
Such a cool story! Love the fact that they programmed it THAT MORNING. Those are the actions of someone driven by passion, not just money! This also has me thinking… I wonder what a tattoo of our logo would look like? 😆
I’ve been in engineering for 45 years. I love it. Metal cutting metal still floats my boat. I would be interested to know what programming software these chaps use. I get satisfaction from every program I write, every fixture I design. I love my job.
I'm a software engineer but I can still appreciate the work that goes into this 100%. I admire the "production" needs of fabrication and machining. Such a different world but same craftsmanship needed.
Titan and these guys have a great thing going that spans across industries. An open mind to the opportunities of what is possible and pushing those limits is beautiful. A negative mindset and discouragement, especially from those who say "ITS NOT POSSIBLE", is disgusting.
growing fast will bring the price down...higher sales...and it blows up when they hit that 1k-2k mark, best of luck guys, great innovative product youre making
I was looking at purchasing one of these propellers for all of the benefits that they provide. I could not pull the trigger as the price was 5x that of my current factory SS propeller.
Toroidal prop. Industry changing. I believe they cut down on propeller cavitation/drag effect in water (and air!), giving more lift/push. Idk im not an engineer. Super cool stuff though. Mazak has some pretty wild machinery.
Lol, they freakin built his product before he even asked them too, thats awesome!!. Glad to see he brought it back here to america. Never should have left, the best people where always in america, just have to find them
Last I heard these were still like 5k... doesn't make sense on a used boat, but if they can get it down into reasonable price rance it might be a cool upgrade even for older small boats. It seems 2 years ago they were 9k so I guess they are making progress towards that goal.
They significantly improve fuel efficiency of marine engines- one test, on a 2x300 hp motor cat, showed a 9 gallon per hour improvement at certain revs/speed. For a lot of applications, esp commercial boats, they’ll pay for themselves.
@@aggiewoodie All great if you can afford the upfront costs. How many Americans can afford a 5,000 dollar Prop? We should all know people in third world countries where this tech could make the biggest difference can't afford it. How many Americans are now living in a third world America because they've been priced out of the first world America? We need to solve the issue of making tech more affordable for all and especially the lower classes where the biggest positive impacts could be felt. We have a handful of people that want to become Mega Rich unwilling to see or accept the collateral damage they are causing to millions upon millions of people if not billions of people.
Previously, I worked in propeller and impeller manufacturing for the marine industry, and I also personally enjoy recreational boating. I don't understand why the Sharrow propeller needs to be fully machined, as typical stainless propellers and impellers are investment cast. The investment casting process is ideal for complex shapes and is also very accurate, which is why only the propeller hub usually requires machining. While the Sharrow propeller looks impressive, existing manufacturers have already proven that propellers don't need to be fully machined. I would be interested in trying the Sharrow design if it were not ten times more expensive than conventional stainless propellers made by Mercury or Solaris. Personally, I wonder if the Sharrow propeller could be made more inexpensively using cast aluminum or a composite material, while still being very durable.
Well, you don't want to turn your product into a commodity... they are getting big bucks from high-value customers, why mass produce a lower quality unit... thats kinda like the "we'll make profit on the volume" bad business model... 🤔
High precision castings are much more expensive though, and much slower to produce, harder to scale up. If the product is as good as they claim, everyone will want one, but, they need to scale the manufacturing up to Mercury/Solaris/et al levels to produce them cheaply, which takes capital. What you're seeing right now is the early adopter tax. In 5 years, they'll be cheaper and everyone will have them.
Weird question, could dimpling the surface of those props increase the props output? Between gold balls, boat bottoms, and now piston tops, it seems like something a cnc shop should explore.
- It would make it worse. The dimples on a golf ball help detach the flow of air from the surface of the ball. Think of a prop like a wing - you want the fluid flow to stay attached or you lose lift/thrust. That detachment is a stall
The prop itself would also need to be thicker to make room for the dimples and still keep the same strength. The machining time could also double compared to now, I am guessing the machine time is already more then twice as long as old classic design props.
The dimples are to create flow sepration and allow the golf ball to slip through the air with less drag. A prop has the opposite problem, you want the flow to remain attached for as long as possible because as soon as it detaches you get cavitation. Cavitation is low pressure where the water boils and then the surrounding water pressure collapses the bubbles. That collapse causes noise, drag, and wears out the prop significantly faster. In addition to that, if the prop cannot grab the water, it can't transmit force into it, and therefore cannot do its job of moving the boat. So, great idea on a car, or a golf ball, but, bad idea on a prop.
Another cool story and example that shows it’s ok to think outside of the box and try different techniques instead of following the pack. The solutions are all within our mind. Just have to go after it and do your own thing. Much love and gratitude.
Hopefully they aren't too leveraged on machine mortgages. If there is a downturn in demand I've seen tons of shops that expand too fast then get hit hard when the contracts dry up.
I don't expect it to last that long. The numbers they got and their advertisers get are by cherry picking props to get the numbers they want. By testing various different props on different boat motor combos I have found the difference between conventional aluminum or stainless propellers can be huge. With one of these sharrow props costing 5-10+ times more than a conventional stainless prop it will continue to be a hard sell. Especially after someone wipes out their new $5k prop on a sand bar. They offer a repair service but good luck keeping up with that. People aren't going to wait a long time to have a small prop repaired. Plus there are SO many different size props its going to be hard to keep up with them all. And the boat industry has major peaks and valleys.
@@sdvten exactly. boats are for rich people. since rich are becoming richer and only 1% of population other 99 are just poor working pleb. unless these guys got contracts from all the ship companies all over the world. but those cncs can still make other parts not only props
Quality parts at crazy high prices you mean... This is a monumentally inefficient if beautiful way of making these props. Investment casting in ss would be so much more suitable and cost effective.
I'm currently learning Python programming and it's very fulfilling,@@PaulG.369. Before the end of 2023, I'll have the skills to do greater things than I'm able to today. You should totally get into it.
Absolutely love to see this coming from Detroit I live 3hrs north of there in the small town of harrison and it’s great to see Detroit coming back to life!!
Wonder where this guy got his marketing money from? These props arent new or innovative, but they've been getting promoted like crazy the last two months.
I mean, they own the patent on them, so, while the idea of a toroidal propeller isn't new, MIT came up with the secret sauce and sold it to him, so, I'd imagine they are 'new' in the sense that they're actually markedly better.
HOLD UP this guy is a dirty liar... he absolutely didn't make this design because its been used on stealth submarines probably longer than he has been alive.
I love how people come up with things like this the way he did..it's honestly amazing the work they are doing us so amazing..I can't wait to see the kinda stuff people can come up with now that machine parts this quick and precise...this and 3d printing are gonna change the world and how we make things for the better❤❤🔥🔥💯🙏🏾✌🏾
Nothing is difficult. 😊 I don't just work there for the money. I see people who do their job with love. And I'm happy If you want to be successful in a job, it's important to love your job I'd love to live there, and work with them 👍👏😊
Those toroidal propellers are a thing that seems so obvious (to try when experimenting) after you see it. Makes you wonder what other slight changes could make a lot difference.
The fact he came up with the prop idea, and just THIS YEAR, MIT did a study and came up with almost his exact shape as the quietst drone prop possible...
“The MIT patent license was transferred to Sharrow Marine which perfected the project, in which the airfoils of the various sections of the blades can be seen, and created and put the product on sale, which it obtained in 2020 at the Miami Boat Show the innovation award.”
I don't care what other people think of Detroit, it's an amazing place with some amazing people, and I've lived in the area my entire life. It really doesn't surprise me that these guys here in Detroit can do what nobody else could.
I was the same way when I was machining. I wanted the difficult parts,it was all about the challenge,while my coworkers wanted the easy stuff. It's what made me a popular prototype machinist which I loved doing!!! To me doing repetitive work was boring as all get out. You got to work with the engineers one on one and help them with the machining process and make suggestions as how it could be done more efficiently. Everyday was like a new job which keeps boredom at bay. While I really miss machining my health made it impossible to continue. Getting old SUCKS!!!!
Maybe I'm missing something, but I don't understand why these propellers have to be CNC machined. CNC machining is not cheap and usually reserved for small numbers of pieces. Casting is far cheaper for mass production. I've seen mass produced parts cast in all sorts of metals that are far more complex than this propeller.
You are totally right. Making propellers is all about making the tooling correctly to precisely cast the required shapes. Machining is only required on the hubs. Traditional stainless propellers have the following advantages. The tips of the blades are more durable. Typical stainless props are stiffer than aluminium and the blades retain their shape under load. This gives a typical performance advantage. The Sharrow prop is however totally different. It’s very strong by design because its loop blades are so well supported. Blade flex off is not an issue. I’m sure this design would probably work equally as well if made from cast aluminium. Aluminium propellers are much cheaper than stainless ones. Tip wear is also far less of an issue with the Sharrow design. I don’t doubt that we will soon see a well made product coming out of China that will tick all the boxes here. Then I’ll buy one as well.
Awesome video, love to see people with such a passion getting it done at insane levels, and someone like Titan bringing all of this knowledge to us! American made👍🏼👍🏼👍🏼
These props go for $5,000 each on their website. Obviously that’s just for now to help pay off 30 heller machines then they should come down to $500 bucks each or the price of a normal prop.

Weird question, could dimpling the surface of those props increase the props output? Between gold balls, boat bottoms, and now piston tops, it seems like something a cnc shop should explore.
- It would make it worse. The dimples on a golf ball help detach the flow of air from the surface of the ball. Think of a prop like a wing - you want the fluid flow to stay attached or you lose lift/thrust. That detachment is a stall
I'd put money on more cavitation and increased prop slip if you do that.
The prop itself would also need to be thicker to make room for the dimples and still keep the same strength.
The machining time could also double compared to now, I am guessing the machine time is already more then twice as long as old classic design props.
The dimples are to create flow sepration and allow the golf ball to slip through the air with less drag. A prop has the opposite problem, you want the flow to remain attached for as long as possible because as soon as it detaches you get cavitation. Cavitation is low pressure where the water boils and then the surrounding water pressure collapses the bubbles. That collapse causes noise, drag, and wears out the prop significantly faster. In addition to that, if the prop cannot grab the water, it can't transmit force into it, and therefore cannot do its job of moving the boat.
So, great idea on a car, or a golf ball, but, bad idea on a prop.
Titan....... This was advertising for a product!!!
..........a US made, product!
Keep on doing videos like this showcasing American companies.
Boom! 👍
Another cool story and example that shows it’s ok to think outside of the box and try different techniques instead of following the pack. The solutions are all within our mind. Just have to go after it and do your own thing. Much love and gratitude.
Proud about all the German machines used in this shop
Germany makes the best machines, with turkish labor lol
Hopefully they aren't too leveraged on machine mortgages. If there is a downturn in demand I've seen tons of shops that expand too fast then get hit hard when the contracts dry up.
Those props will increase in demand as they are more efficient.
I don't expect it to last that long. The numbers they got and their advertisers get are by cherry picking props to get the numbers they want. By testing various different props on different boat motor combos I have found the difference between conventional aluminum or stainless propellers can be huge. With one of these sharrow props costing 5-10+ times more than a conventional stainless prop it will continue to be a hard sell. Especially after someone wipes out their new $5k prop on a sand bar. They offer a repair service but good luck keeping up with that. People aren't going to wait a long time to have a small prop repaired. Plus there are SO many different size props its going to be hard to keep up with them all. And the boat industry has major peaks and valleys.
@@sdvten exactly. boats are for rich people. since rich are becoming richer and only 1% of population other 99 are just poor working pleb. unless these guys got contracts from all the ship companies all over the world. but those cncs can still make other parts not only props
Greetings from da UP! Glad to see "Made in Michigan!"
We have a röders and also make props like that
Worked in cutting tools for cnc many years,brilliant businesses out there producing amazing products
Quality parts at crazy high prices you mean... This is a monumentally inefficient if beautiful way of making these props.
Investment casting in ss would be so much more suitable and cost effective.
I'm not in the CNC business, but this video is very inspiring. It makes me wanna do something great with my life.
I'm currently learning Python programming and it's very fulfilling,@@PaulG.369. Before the end of 2023, I'll have the skills to do greater things than I'm able to today. You should totally get into it.
It's crazy to me how much blah-blah of telling the same thing thrice is in this video.
Still a great story, though
Absolutely love to see this coming from Detroit I live 3hrs north of there in the small town of harrison and it’s great to see Detroit coming back to life!!
05:30 this guy really just claimed to have invented the toroidal propeller? 100% untrue.
Sharrow props for the sneaking up on the enemy in naval battle win
Wonder where this guy got his marketing money from? These props arent new or innovative, but they've been getting promoted like crazy the last two months.
I mean, they own the patent on them, so, while the idea of a toroidal propeller isn't new, MIT came up with the secret sauce and sold it to him, so, I'd imagine they are 'new' in the sense that they're actually markedly better.
@@jttech44 Doubt it. Lets see the metrics not just marketing bs!
I hope this takes off like wildfire. It would be great to see most of our parts made here in the US again.
HOLD UP
this guy is a dirty liar... he absolutely didn't make this design because its been used on stealth submarines probably longer than he has been alive.
Cool story and cool manufacturing. Great video!
Nobody?! LOL! Your world is not very big and comprised of a single country I guess.
Best Maschine Heller, Hermle made in Germany 👍👍👍👍👍👌👌😍😍 have a great Time
I love how people come up with things like this the way he did..it's honestly amazing the work they are doing us so amazing..I can't wait to see the kinda stuff people can come up with now that machine parts this quick and precise...this and 3d printing are gonna change the world and how we make things for the better❤❤🔥🔥💯🙏🏾✌🏾
Nothing is difficult. 😊
I don't just work there for the money. I see people who do their job with love. And I'm happy
If you want to be successful in a job, it's important to love your job
I'd love to live there, and work with them 👍👏😊
I think the machines are smarter than the people on this occasion
I saw their Props a few weeks ago at the Miami boat show. The finish on them is incredible!
Making America Great Again. Awesome !
Those toroidal propellers are a thing that seems so obvious (to try when experimenting) after you see it. Makes you wonder what other slight changes could make a lot difference.
Very impressive. Manufacturing ROCKS!
The fact he came up with the prop idea, and just THIS YEAR, MIT did a study and came up with almost his exact shape as the quietst drone prop possible...
“The MIT patent license was transferred to Sharrow Marine which perfected the project, in which the airfoils of the various sections of the blades can be seen, and created and put the product on sale, which it obtained in 2020 at the Miami Boat Show the innovation award.”
Hypnotic 😵. I could just watch the machining process.
I don't care what other people think of Detroit, it's an amazing place with some amazing people, and I've lived in the area my entire life. It really doesn't surprise me that these guys here in Detroit can do what nobody else could.
great jobs on 5 axis high speed machining. before i retire, i use to teach 5 axis programming and machining. great jobs guys.
That is so awesome it's really nice to see machining in the USA keep up the great work
As a retired CNC salesman, I can say the Heller salesman and dealer are happy campers.
I was the same way when I was machining.
I wanted the difficult parts,it was all about the challenge,while my coworkers wanted the easy stuff.
It's what made me a popular prototype machinist which I loved doing!!! To me doing repetitive work was boring as all get out.
You got to work with the engineers one on one and help them with the machining process and make suggestions as how it could be done more efficiently.
Everyday was like a new job which keeps boredom at bay.
While I really miss machining my health made it impossible to continue.
Getting old SUCKS!!!!
They're beautiful 😍 Great video of 2 awesome companies doing crazy things!
I was on the fence about purchasing the prop...... I'm buying now. 400hp Merc
Titan. Good inspiration and the other guys. Thanks!
That's keeping it real, keep our work American-made! A+ guys
Awesome job MADE IN AMERICA 🇺🇸 KEEP IT UP .
Maybe I'm missing something, but I don't understand why these propellers have to be CNC machined. CNC machining is not cheap and usually reserved for small numbers of pieces. Casting is far cheaper for mass production. I've seen mass produced parts cast in all sorts of metals that are far more complex than this propeller.
Even near-net castings usually have some finishing for functional parts like this
You are totally right.
Making propellers is all about making the tooling correctly to precisely cast the required shapes.
Machining is only required on the hubs.
Traditional stainless propellers have the following advantages.
The tips of the blades are more durable. Typical stainless props are stiffer than aluminium and the blades retain their shape under load. This gives a typical performance advantage.
The Sharrow prop is however totally different. It’s very strong by design because its loop blades are so well supported.
Blade flex off is not an issue.
I’m sure this design would probably work equally as well if made from cast aluminium.
Aluminium propellers are much cheaper than stainless ones.
Tip wear is also far less of an issue with the Sharrow design.
I don’t doubt that we will soon see a well made product coming out of China that will tick all the boxes here.
Then I’ll buy one as well.
Cleanest shop I've ever seen.
Heller is one Hella‘ of a Machine 😎
This is the coolest job ever, basically a modern day sculptor!
Awesome video, love to see people with such a passion getting it done at insane levels, and someone like Titan bringing all of this knowledge to us! American made👍🏼👍🏼👍🏼
I am feel inspirated this story. Amazing guys!
Great installations! Congrats!
These props go for $5,000 each on their website. Obviously that’s just for now to help pay off 30 heller machines then they should come down to $500 bucks each or the price of a normal prop.
