Vessel of boiling water, silicone, a drill bit, a nail, and a small block of wood. I would love to see this Incorporated into a script say for someone stranded because of a bit of tubing. This is so Macgyver or something I could see a character in a Zombie movie having to do. Fucking brilliant!!!

This is brilliant! Adding dishwashing detergent to the water will keep the silicone from sticking to itself.

What an excellent video, thorough explanation, detailed procedure, great sound quality and wonderful attitude. Thank you for sharing

That was awesome! So many ideas are now flooding my brain that I want to try! Lol, I never knew you could DIY extrude silicone like that until I saw this! So thank you, I will definitely be experimenting and sharing with fellow mates to try as well! Cheers!

I'M IMPRESSED! THANKS FOR MAKING THIS!

Man! This is great thing you've done here! Thank you very much!

Dude one of the best videos I have ever seen.

Fantastic idea, research and development. Thanks for sharing your great content. 👍

Smart extrusion mould man. Adding that to my repertoire! :)

This is awesome.

wish I could give you one more like so that atleast 500 likes to complete. one of the best videos.

Super cool idea!

The technical term for cutters is actually "snipy snips"

Awesome video mate!. Thanks for sharing

Holy crap that is crazy! Im going to try and make some of this tomm. Thanks!

You sir are brilliant

Awsome Engineer Nick👍

Oh nice- I like this and it can be so useful a method. Learned something very nice to know about today.

This is what I call a true DIY

Great work. Thank you

very clever, thank you friend.

That was really clever and cool

Great video!

what an idea SirJi...

Thanks Nick. Nice

Really helpful. Thank you.

great video.

Since this type of silicone is moisture cured (I think the correct term is condensation cured), it might speed up curing on the inside by removing the squashed ends when the tube is firm enough to handle and put it back in the water to allow water into the tube.

Simply outstanding!⭐⭐⭐⭐⭐👍

Brilliant.

This video is very helpful for me; Thanks alot :)

Wow you are awesome.

Dats dope broooo ...

good idea...thanks

A good information.

Good job

Wonderful!. Regards, Engineer from India.

Just tried this and it worked amazingly! The hot water is a great idea, and appears to make the silicone cure quickly while preserving it's shape. Awesome!

awesome vid..

Thanks for sharing fantastic

wow. this might be a perfect way to create a thick silicone tube that I can wrap dowels with and make flower sticks 🤔

thank you sir, yo are a genius

it is genius !

I wanna try this

Awesome, I was wondering how did you make the hole? Interesting method, I would never think about it.

is that your average everyday 3% hydrogen peroxide? GREAT video thanks. Silicone actually needs moisture to cure as does ‘super glue’. If you were to line that block with some kind of anti-abrasive you’d get nice smooth walls (I’m guessing)

Fuckin nice bud! If I ever need to make an extrusion mould I know the easy way now.

Mind = blown

You are brilliant! I may never need a silicone fuel line, BUT you never know when custom silicone tubing for one thing or another is needed and nowhere to be found. I use vinyl tubing to pump out hydroponic tanks and it's too stiff and unwieldy. My silicon air pump tubing, on the other hand, is far more cooperative. Thank you so much for sharing this. The jig made it all possible. Maybe a two-part polymer clay mold is your answer to a reusable jig. Once the silicone sets up, you could take the polymer clay mold apart and cut out the silicone plug.

thanks man :-)

Metal block with intersecting hole hole drilled for mandrel from bottom of chamber allows multi use extruder that can be cleaned. using a set screw in the side of block allows different drill bits for inner tube sizing

Boa ideia

wow your good

I did this it works but i used cold water with dish soap

That is fantastic. Thanx for video.. Like others you were probably told too smart for own goood. Be carefull

I'm pretty sure you can buy casting silicone that would handle the fuel no problem at all. Even the expense of that would still save you money if you extrude it this way.

Very cool, silicone tubing! Maybe you can make a reusable mold with silicone too? Or would it stick to itself?

Nice, but how much max pressure it can take.

Good job... but I'm wondering if that silicone is fuel resistant

Can you make video how to make o"ring

Very clever but I hope you realize that silicone is not resistant to fuel. Normally silicone tube needs to have a fluoropolymer lining to be resistant to fuel and oil.

Is it can brake?

Have you found a way to get rid of the stickiness / tackiness of the extruded tube? Or the proper ratios to cure it?

This is a seriously clever idea. I think if you ran a bolt or a screw through the block from the other side; you would be able to clear that blockage. For a wooden block on this small a tube its not such a big deal, but this idea has potential to make much bigger lines. I am building a gold prospecting suction dredge right now and I have been really needing better tubing. Making my own lines out of silicone rubber hadn't even crossed my mind. A couple of tips from what I have learned with my own experiments: Thin the stuff down with toluene and add color to it and then use a basting syringe instead of the caulking gun. I think you'd have a lot more freedom with that and way more options. It may take some tuning to get the silicone thinned down to the right degree. Since it would be runnier I think it would be better to have it closer to the water and make the water deeper. Again, not such a big deal on a tube this size, but if you go bigger you'll benefit. Plus being able to color it and reuse your die is all nice too! Sub earned!

I doubt polyethylene or polyurethane is what is "commonly used for fuel line", because last i was at Conrad looking for silicone tubing, most of it was marked "fuel line", and conversely, looking for "fuel line" delivered silicone tubing. :P It also barely cost anything, like less than 2€ per meter off a roll. And it's even cheaper than that on eBay from nameless suppliers, last time i had to order much thicker tubing that has a lot more material in it, it came out at about 3-4€ per meter shipped and delivered in 2 days. The ones from eBay claim to carry a food safe material certification on it, which even if the certification is fake, probably means it's titanium catalyst, high temperature cured, and should actually be very solvent resilient. I guess there are other ways to make other kinds of silicone somewhat solvent resilient, like post-cure at high temperature to convert some of the residual products too. Congratulations on successful extrusion setup experiment, that is certainly good to know just in case.

haha that is good idea

I'm just curious about the long term use, wear& tear issues and what not.. Does it dissolve or harden in fuel? How does it hold up in longevity test?

how long will it take to become hard? is it suitable for any kind of silicon?i mean if i use medical grade silicon.

Tear strength

i want to know the liquid you added in hot water.and also can you tell me that how much temperature will this pipe bear?

🖖 👍

So..How did it work out - long term test/review?

Interesting video, but silicon tubing is much cheaper than you were quoted

You can buy Fuel silione tubing very cheap by the roll or meter if you knwo where to buy, PTFE tubing is even cheaper, and totally fuel safe. Basic domestic Silicone is NOT suitable, you need an oil grade silione it will otherwise degrades very quickly !

Any updates to this hows it working for you?

Are additives really needed?

Excellent - however fuel line is easily obtainable and cheap off eBay especially from china !

This work with rtv?

в воду что добавил?

hey nick

I’d gonna fail and you may burn, hell PTFE for super car not that pricey. Great video, clever. Do not do this! Silicone is inert but that’s a disaster, it’s make different not from that under vacuum or pressure. Is this just a joke? Or for a model? Antiseptic isn’t sane as 6-food grade, chemical, jet propulsion stuff. I missed a part? Guy was messing about prices. Seriously no way in gasoline or any thing depend on.
