Make a set and send it to the YT braille channel: "you make it we skate it". Then you'll have a definitive answer 😁

This cat is innovative as heck. I enjoy the videos greatly and I sure hope to try some of his ideas when I finally figure out Blender!

Hi Chris. Smooth-On PMC-790 Urethane requires Post Curing, quote - "After rubber has cured at room temperature, heating the rubber to 150°F (65°C) for 4 to 8 hours will increase physical properties and performance." Have you tried that too? Some industrial grade urethane can be heated to 240F for 40 minutes. Its cool to play with post curing. It should increase a wheel life span.

Another perfect example of what 3D printers allow… you don’t have to pay 6000€ for an injection mold just to try an idea, great work 👏👏👏 About the broken pieces, I would suggest making a full enclosed 3 piece mold with two entrances in one of the side pieces and fill it with vacuum.

My man 3D printing everything lol

Great video! I saw some other viewers already mentioned the shore hardness scale and converting A to D. I've looked into making wheels a few times (haven't done it yet), and I like the look of Smooth-Cast 57D as a starting point for harder wheels (57D appx = 99A). It has a really short pot life, but does have a much lower viscosity and cures pretty fast, according to the specs. Great job with the mold design and fabrication. Thanks for sharing! Looking forward to seeing more!

dang, that looks pretty good.

This channel is gonna blow up👌🏼 keep it up!

Congrats on 1k! You are going to go far!

Top job! Enjoyed that!

This is a wheely good video.

freaking epic bro!! great work! can't wait to see what you do in the future!

Man stumbling across this channel might be the highlight of my (youtube watching) year. Cant wait to go through all these videos and start some new 3D printer projects. Awesome work and thanks for sharing!

I'm looking at making rubber grips for my steering wheel and this video was pretty helpful, thanks!

Might consider checking out Smooth -on's KX Flex 90. Has shore hardness of 90A with a 2.5 minute pot life and a 20 min handling time along with a 24hr full cure.

You are crazy underrated bro!! Keep up the unique and good quality videos

It looks so cool

Great content, keep it up!

The result looks great

yeah buddy! looks like a pro wheel nice work chris!

The video quality on this vid is top notch! You'll reach 10K one day . Greetings from holland. Keep on skating and stay safe 😁

Ohhh Mannn I love u! jaja keep up creating and sharing !!

Hats off to you sir as per norm 🤜🤛

an idea for the part that keeps breaking. carriage bolt and wing nut. carriage bolt goes up through the bottom and wing nut locks the top piece in place. just and idea. hope it helps. also, if you end up getting harder urethane and still want to make some soft wheels (like for long boards), use the harder urethane to make the cores. Idk how long your your 3D printed cores are going to last. but either way. Great videos. You are living the dream man. And I'm so stoked for that next video in the snowboard build series.

Well done man! For resin suggestions have you looked in to shore hardness D instead of A? A100 would be around D60. Also I don't think it matters if it is called polyurethane rubber or just resin. I think the 'rubber' is just because it is on the soft side and not any specific property intrinsic to the term. Polytek have some resins like "Poly 81-90" that you might find interesting. Smooth on has the "Task 21", but these suggestions are just my first glance.

woah ur vids are so cool

Thanks for show this nice video

This is awesome. I am thoroughly impressed good sir! I'm new here but I do a lot of 3D printing for work and one of the things we do to make our parts strong when the geometry can't really change, is to fill the parts with an epoxy, or polyester resin. You effectively get strength better than 100% infill without having to change the geometry. you just have to make sure your infill pattern isn't celled (like rectilinear). Hope this helps!! really looking forward to the follow up on this video 🤙🏼

Your reaction is HYPE and so is the channel!

Hy chris am looking for 3d wheels molds all size how can i find it please help me

It would be great if you made a fingerboard version!

You could add a metal bolt in your top piece thats print modled in, that way you would get a metal thread and bolt point, the only way I have ever beating the 3d printed thread to torque breakage is by printing the bolt laying down on the print bed .

Any luck on the harder urathane?

Send some to Braille Skateboards!

Saw another channel he cast the wheel with a silicone mold first maybe that will help instead of 3D printed mold and core. I’ll look around for urethane

Where can I buy one

Take a look at Forsch polyurethane. They're used a lot in making suspension bushings for vehicles.

you could leave the central axis of the mold hollow and just bolt them together... threads cant break off if they aren't there

Dude this is pretty freakin cool. Nice work! I'd be keen to design a wheel for LDP, big diameter, lightweight, efficient and smooth ride...

You just need to put your front foot a bit more backwards so you have more space to drag it up,align your shoulders with the board and dont look down,that prevents you to go higher! Good job with the cast,looking forward for more ;)

Have the mould machined out of aluminum! The 3D print proved it worked but because 3D printing is done in layers, the layers splinter under the torque as you twist it apart.

Embed at standard threaded bolt in the mold - is that possible? And maybe a nut on the other end of thread if that end is not at least 2 times longer than the thread with. Else hybrid system - a machined inner par - and 3d outer / end part for various outside profiles. 🤔🤓 Cool vid!

Have you tried looking at bowling ball urethane?

Para patins online fiz 8 ensaios com pmc-790 mas achei pouco resistente. Chegou a testar a dureza nas rodas que você fez? Como não tinha nenhum núcleo para colocar, não tive como testar muito. Com meu peso e ao aquecer, os rolamentos ficaram soltos dentro dos alojamentos deles. Pouco consegui testar.

hey man, saw your post on facebook but cant find it again,lol. looks great, deffo subbed. i know with epoxy if you heat it a little it can change the viscosity to make it pour better. also for your mold. have you considered using a bolt or something you could design into the mold, if that is your weak point. anyways good stuff man

Nice :)

Try mixing hardener That's used for bondo

I think the urethane might be getting in the threaded part of the mold. If you end up redesigning the mold, i would try to make the center of the bottom part go further up, and have the top slide over top of it like a bracelet before screwing on. Sorry for grammar.

you may want to ask some more professionals about using a pressure pot with flexible rubber or foam urethane. the pot works by compressing air bubbles so that they are tiny and trapped, but those collapsed microscopic bubbles are still under pressure. The less rigid rubber or foam urethane may allow the bubbles to expand and distort or damage your part when returned to atmospheric pressure. I think this what happened with your pigment tests (the fabric dyes contain moisture which foams the urethane and you pressureized the pieces which why they exploded when taken out). You may do better with a vacuum pot which will evacuate the air bubbles and free up your pressure pot for other projects. get a long pot life resin, vac the cup, pour 70% full (because it will foam and overflow), vac the mold to get surface bubbles out, top off the mold, let it cure in atmosphere.

I've heard the best wheels are poured hot

hey bro, why don’t you have them cnc after you make the mold or just ask someone to make the mold with metel?

u r amazingly smart

thats fantastic. weird that you still got a bubble with the pressure pot

Your ollies would improve much faster on a board with some camber to it. Great video but why did you pressurize the mold?

congratulations! its a wheel!

Can you give the link for the mold design

Doesn’t smooth on make a pot life extender?

How much? Labeda makes wheels for yak at like 50 cents each

How many bar in the bottle?

I skate 90a wheels that have no cores?

Since the threaded insert keeps breaking, maybe design it around a big ass metal bolt? Takes away the charm of having it fully 3D printed, but wouldn't have to worry about the threads anymore.

Your problem with the thread on the mold might be solved by changing the print direction of the part... I'm guessing that you printed it so the the layers are horizontal with the thread which makes it to the lateral pull that accures when you tighten it... Try turning the part 90 degrees i think that'll do the trick ✌️

Hey man may you can help me to make my own skateboard at home

did you end up abandoning the snowboard project?

Me: hmm can't seem to find good offset wheels, I wonder if i can cast my own freestyle wheels, finds this video, yupp seem like it will work.

Do a how to make grip tape pls

Please i need your help

Why did you put it in a pressure vessel? Does it matter? It is not normal if I did not use it and let the wheels dry in 48 hours

You should contact someone who makes wheels in the UStell them your making hand made artisans Wheels I bet they would hook you up Someone like nhs santacruze or shortys
