7:30 the spherical shape maximizes volume for minimal surface area, you said the opposite but close enough
(when you maximize surface area for a given volume, you end up with a fractal-like pattern)
Spheres: Maximum volume for minimum surface area. He had the right word for the wrong dimension. Or the wrong word for the right dimension. Lysdexia is a hell of a drug.
We had a lot of fun making this video for you guys! If you are looking for projects for your students or apprentices, this is a great option! Also, shout out to our editor Corey for putting in a ton hours on this video, he's a beast!
I built a hail tester (ice ball cannon) for a solar panel test lab last year. They use custom molds like this and launch up to 80mm balls at speeds between 60 and 100mph. It's great fun to watch. Forwarding this video to the lab now, thanks Titans.
That’s awesome!!
Man Jessie, it must have taken you MONTHS to teach Trevor how a 3 axis mill works! Good Job!
BANNED 😆
I deserve a medal after that undertaking 🤣🤣
Make a ice sculpture in the 5 axis mill
I've been saying that for awhile now! Would be sweet to do on the 5 axis! Just have to cut fast before it melts😅@@importanttingwei7747
@@importanttingwei7747gets ya a nice rusty result😂
I keep thinking about making one of these, only in 110 copper, for maximum heat trannsfer. Also, most of the commercial ice presses have a built in "gutter" to handle the melt eater and channel it away, ideally with a drainhose you can dump in a sink.
Very cool! This project really showcases Trevor’s background in molding. Nice work! 😊
Agreed! 💪🏻
Truly blew my mind seeing it melt so fast in person without any heat...😳 Very cool Trevor! Nice work shooting/ editing Corey!👏
That was a lot of fun to watch! Great video!
So nice boom ball 👏 👌
Nice! The different shades of blue are a defect of anodizing, it was made specially, or maybe it's the different angle of light in the recording?
Could be the anodiser messed up or the 2 bits of aluminium were a slightly different grade.
I make some parts that have to match. we make the parts out of the same bit of plate, then have them plated in pairs so the bits that bolt together match perfectly.
Some times the same grade of aluminium but made at different times will have a noticeable different colour.
Some times anodisers are rubbish at what they do and blame the aluminium.
That’s awesome!!
Great Video Trevor!
The anodizing looks impressive but I'll never get tiered of seeing freshly machined aluminium look, also good to see Trevor branching out from the EDM and Additive into milling, great work!
I think Barry thought I was lost for a second 🤣 Thanks for watching!
The anodizing doesn’t even match. They obviously ran them in separate batches. It looks terrible.
@@joshuaorange8290doesn’t look terrible but it’s annoying it doesn’t match
Now I just need to find some whiskey to go with the ice 🥃
Very nice guys!
What's cooler than being cool? Having Trevor serve up some Manhattans with custom ice orbs at your next party!
Good stuff!
Wow, so cool idea
Nice!
vids have been top notch lately
It bothers me that the anodisation is off between the two halfs....
LOL there ya go, Trevor HAHAHAHA
Yeah that was out of our control, sorry! It bothers me too lol
Maybe find a different anodizing company that lives up to the quality that comes out of your shop. Keep doing awesome work, guys!
Did you mean to say the spherical shape minimizes the surface area? Just curious. Thank you!
no, he said maximizing the surface area. Where he is wrong is in saying it well melt slower as a result.
@@JukeboxJake Right you are!
Very cool bro! Pun maybe intended. I'm going to need to test out that melts in my drink slower bit.
Now that’s smooth! Would be cool to sell them in the store 😉😉💪
You should try copper. The thermal conductivity is higher than Aluminium. And it's heavier. Though the gravity part will also be better.
Yeah agreed, copper would be amazing, if only it didn't make the cost go through the roof 😂
@@trevorgoforth8963 I didn't say, it would be cheap... 🤣🤣
@@Dirk-Ulowetz Haha touche'!
6063 Aluminum has a higher thermal conductivity than 6061, however the higher density if copper would be also a big plus. Add chrome please.
Nifty !
It would be cool to machine a big ice sculpture. I don’t know how long the ice would last being milled but it could be cool to try it.
Tried to find it in your shop to buy but it’s not there 😏
what dimensions did you make your block and sphere? i really want to make one of these
6:39 That is Awesome
Very nice!! But was there a difference in the color of the anodizing of the 2 parts?
When you can tell that from a video you know their anodizer isn't great at his job
Cool.
The square ice silicone tray, where did you get it? Looks like 3inch cubes?
This has to be in the Top 3 Titan’s Video 2023 🎉
The day I never thought would come. Trevor has somehow come to his sense and started doing some real machining🤯
Haha yeah I catch on quick after a while 😆 can’t let Barry and Jessie have all the fun!
That's Bad Azz 👌
Trevor, that was a pretty cool idea. Looked like a lot of fun to make and use. BTW, what drink did you put in the glass with the ice ball? 😁
Thanks Jeremy! It was… apple juice 😆
What's the song @ 4:50?
Hey titans, have you tried using hot water in the freezer? i know it seems like nonsense but this way there wont be any disturbings in the water before freezing
Love it u remind ne of the old TKOR
You guys have the CAD model for this on Titan Academy? ❤
If the ice melts slower, it also cools your drink slower. The melting ice is what cools the drink, not just conduction
Nice, now where can I buy such a cool ice make?
Is there somewhere I could find the 3D model?
Nice golf swing, whats your handicap?
I need this in my Bourbon glass.
I know what my next project is now!
I'm interested in becoming an CNC apprentice how can I apply.
3:46 nice straight chamfer
Very cool! You guys need to talk to your anodizing vendor about color matching though…there’s no reason that two small parts like that should be so different. I could do better with my 5 gallon bucket setup and stovetop dye bath.
I agree completely. Video and product are outstanding, but the color difference between pieces is significant.
I wonder if you engraved the Titans logo on the inside of the sphere in the mold, if it would emboss onto the ice
Doesn't RO+deionized get pure water that can be used to get clear ice?
The spherical shape actually minimizes the surface area (surface area vs volume ratio is the smallest in a sphere) thus delaying melting.
Every bar in Dallas is your customer$$$$$$
Could we see a 5 axis golf ball ice press next?
Is 6061 aluminium more common in the US than 6082? In Europe I can get 6061 only as a sheet.
Yeah, 6061 is probably the most common grade here in general. You can get it in almost any form
Hi, how much does it cost?
None of you Dorks noticed how pure his swing was on the ball LoL. Dude was a baller back in his day
Haha thanks for noticing man 👊🏼
I know what I'll be making in the new year
Cool Trevor, smooth ice balls and without vibration marks like Barry always makes 😂
Just joking Barry
What if the block was made of copper? Theoretically, copper has better thermal conductivity than aluminum. Is this one worth trying too? I'm curious
Why are they different colors?
Is the mismatched tones of blue purposely done?
When you were talking about gravity, you forgot to mention it’s the pressure from the weight of the top half that lowers the melting temperature. You aren’t pressing it into shape as much as melting it into shape.
RR at GMG down the road needs about a hundo of those for all his bars😅
Different shades of blue to tell when the ice ball is ready 😅
anodising makes the part grow (and thus holes smaller)
Click Clackidyy Duck, Trevor what the F$$$
Kool video but next time, put some respect behind that swing.. ;)
Come on now, you know that ice ball went 450ft for a home run 🤣
He keeps saying he is an athlete, but after seeing that swing I don't believe it lol
@@Jessie_Smithlol, Rookie of the year
@@trevorgoforth8963 👀 mmhhhmm 🤨
Make Donnie do all the work 😂
No mention that the blue colours are different?
Ya, haven’t found decent anodize shop yet… they even racked on the outside instead of in the holes
Meaning in Texas
You guys should sell these
I wonder if they could of laser'ed there logo into the middle of the ice? that would of looked cool.
The spherical shape MINImizes the surface area not the other way
7:29 minimize, otherwise fun video!
TAKE MY MONEY!
He said that it’s going to maximise the surface area of the ice bal but I think he meant minimises😅
When are they going to make me an ultra precise yoyo?
Why the difference in blue?
6:30 fushigi
the ironic thing is that with a clear ice ball, you can likely light a fire by using it as a lens.
Wonder if many new machinists can build anything manually anymore? I know cnc speeds up everything but nothing better than manually machining parts.
Wish I was smart enough to learn machining and cnc operating 😞
The sphere shape minimize contact area.
Now make out of copper and test this ball making race hehe
The QC on the anodizing is kinda bad
There was no QC on the anodizing because it’s not going to a customer. We aren’t thrilled about it either but parts like this would never go to a customer.
If you did not do the anodizing in-house, then you should really consider giving it a shot.. those colors are off. One was soak or anodized longer than the other.. I would be complaining for my money back. Lol unless ofcourse, it was done in-house..
"Take all coldness from the ice."
Are you sure that is how it works?
Those ice balls are so cold that they've become aluminumb...
I'll see myself out.
I dont want to be that guy, but if you have the cnc ready why didnt you put your logo inside the mold so it would be imprinted on the ice?
Why not machine some heat sinking fins at least on top and bottom so that the press cools down to ambient faster?
"Takes all that coldness"
funny thing to say when you wanna get scientific :D
You cant take coldness, nor can you really cool anything
you can put heat somewhere else.
Thats what you can see with your thermometer, the aluminium loosing heat energy to the ice, thats the way heat energy travels.
Otherwise nice vid
I thought copper was better for this kinda stuff?
The easiest way to get crystal clear ice is to use distilled water.
Why are they a different colour? 😂
Entertaining video, but -
boy, oh boy did you get the whole "The Science of WHY IT WORKS?" part wrong ... breakdown in followup comment.
6:47 "race to reach an equilibrium" somewhat true, though the 'contestants' 'race' towards each other and the equilibrium is wherever they meet. Is that still called a race?
6:58 "coldness" isn't something, it's the absence of something: heat energy. Sounds nitpicky but it leads to so many misconceptions. It's not like you can put "more coldness" into something to make it cooler, you can just try to get more heat out of it until there is no heat left. (also known as 0°K)
7:20 "[...]weight of the top piece and the gravity in our favor to help press that ice into our nice spherical shape" crystal clear ice is pretty hard and brittle. Changing the actual shape by simple downward pressure would crack it.
The actual way gravity helps in this application is that the weight of the press pushes aside the liquid water to keep the best thermal contact between the metal and the solid ice. Water is not a good thermal conductor so the melting is slowed way down as soon as the weight rests on the base and a somewhat insulating liquid layer is formed.
7:27 "the spherical shape of the ice ball actually maximizes the surface area" the spherical shape actually minimizes the surface area.
Less contact area compared to the volume leads to less heat transfer leads to slower but longer cooling (and less watering down)
Oh geez you’re one of those guys huh? Who the hell cares? Just enjoy the video.
Pretty sure you’re wrong yourself in that this doesn’t use thermal conductivity to melt the ice. It uses pressure.
@@ReefMonkey
Yup, I'm one of those guys that are disappointed hearing grown people argue "have you heard of that machine that almost reached the coldest temperature? I bet if they put in a giant freezer they could even reach negative temperatures."
If by "It uses pressure." you are referring to the legend that ice skates liquify the ice underneath them by sheer pressure, you might want to look up the pressures needed.
We are talking thousands of atmospheres. Between 2 million and 30 million psi.
On top: If you manage to just use pressure to melt the ice it doesn't get warmer. As soon as you release the pressure it'll refreeze.
What happens in ice presses is that every bit of ice that touches the press is melted away and the bits that weren't touched by metal are those in the nicely machined spherical cavity.
That part would melt eventually but the heat energy needed takes longer to get through the liquid layer.
I should kick myself for not getting into this field when I was younger.
If you want clear Ice you have to freez Boiled water. Trust me its true
Its air, not impurities. Now start a fire with ice video short. Your welcome.
Now fuushigi tricks
Whoever anodized that needs to get fired right now 🤮
You slipped up slightly in the science part. The sphere *minimizes* surface area, not maximizes. All the rest of it was right, you just used the wrong word.
