yes i realise now that i said making latex FROM rubber... and i stand with what i said, not one of those self correcting booger butt type nig nags..

Not quite that simple. Water tends to dissolve a lot of things, too many things. So a different solvent is required. That is one thing I was/am working on for the next video about this subject, finding an easy to access solvent (or series of solvents) that is selective for latex.

Extracting rubber from dandelions? Not that I'm aware, it doesn't release any CO2, and it can easily be grown as a 'circle crop' (all the plants that are used are re-grown, rather than having to expand outwards like many logging operations. Biggest downside is yield.

@@evilplaguedoctor5158 ok

Nope, just a 'normal' north american verity I had growing in my yard. I did order some russian dandelion seeds, but dandelions are suprisingly hard to grow when you actually want them to grow.. (I couldn't even get them to germanate) And absolutely give it a shot!

What is it good for? I drink the tea to help diabetics . But the latex good for

I'm assuming you're asking for help to build a cnc machine of your own. Sure, what kind of help do you need?

I used a cutting board, (they tend to be made of a slippery type of plastic) drilled them out, and put them in a short piece of pvc conduit (stores typically only sell them as 10 foot lengths though)

This type of cutting board is almost always HDPE, high-density polyethylene plastic. UHMW plastic would be slightly more durable and smoother operating in a production setting, but cutting board material is practically free compared to UHMW. To the OP, thanks for posting, this is genius-level thrift! The combo of hole-drill and forstner bit for custom bushing sizes is terrific workaround, thanks!

Not yet in condom, but Continental Tires has been attempting to use it in tires.

Hey! looks like I'll be doing a video about starch plastics first while I wait for some more of my algae cultures to grow :) But thanks for watching & staying up to date!

@@evilplaguedoctor5158 can you make synthetic rubber from starch too?

There is a place in Russia trying to make it commercially viable, but due to how cheap latex is, and the small amount dandelions give, it doesn't seem to be very financially viable at the moment. as for ways to vulcanize it, I'm not sure.

@@evilplaguedoctor5158 Moonflower (Ipomoea alba) contains Sulphur. It's said that it was the plant which was used by mesoamerican civilisations to vulcanise latex. I saw a video somewhere on here of the process done in recent times. They basically just heated latex with moonflower juice in a big pot.

I believe I read vulcanization takes place at 150C. I'm unsure of the reaction taking place during acid coagulation. Maybe there's some form of sulfur as a byproduct that could readily vulcanize it at ambient temperature. Regardless it may be a good option to kill two birds with one stone if one can use it for coagulating first then vulcanizing even if at high temperature.

Unfortunately crushing dilutes it to much in its sap/water. One thing I'm trying to figure out is how to separate it from that method (Im thinking vacuum distillation...) As for making it useful, it really needs some stabilisers or something since this method makes the latex quite crumbly.

@@evilplaguedoctor5158 well I saw a video of a company that built a tire out of dandelion rubber so I should be able to make my own condoms

@@Doctoranthetardis I'd love to see your partner's face as you put one on

I honestly forget, I do remember that being a problem. I think I ended up using epoxy resin. Although ultimately I ended up biting the bullet and getting real linear bearings because I was getting issues with it binding (everything has to be perfectly straight, or else it'll bind) Good luck!

Let me know how it goes! I'll admit, I haven't tried bigger quantities, nor am I sure how well it'll work for something like that without any additives/stabilisers. 😀

EvilPlagueDoctor That’s what the ammonia and zinc oxide are for that’s what the factories add (or if they want solid rubber they just add formic acid)

Just so you know, the latex from milkweed is mildly poisonous. Not very, and the processing might break down the poison into something benign, but it's there

That would be really interesting to see! because I honestly Have no Idea.

Matthew Wilson The ammonia keeps it from drying too fast The ratio I would choose is 1 cup of latex and 2 tbsp of ammonia Pour it into a gallon jug And repeat until jug is full

Yes (in theory) that's what the Russians are working on (helped by the fact that russian dandelions already have a high yield). but even with a high yielding dandelion, the latex output pales in comparison to what the rubber tree produces. so it's not a great business model if that's your plan :)

Awesome! I'm glad to hear that.

The Germans are also working on this. They've already started producing tyres made from Russian Dandelion rubber which perform exactly the same as tires made from rubber trees. It's likely that we'll see more rubber production from Dandelions as industries develop to take advantage of this new source. Also worth noting is that the Germans crush the entire root stock to get to the latex, rather than bleeding the roots, as was done here and as is done to the rubber trees.

@@evilplaguedoctor5158 I'm sure "Climate Change" will have something to do with them (you know) changing that.......... Eg; Borneo deforestation due to latex production. It's not necessarily a terrible thing to hold back on clearing forest for new plantations and change mono-cropping to more diverse plantings - but it's fairly likely they would also raise prices/add "Climate Change" compliance rules, etc...until dandelions are #1. At that stage and with all the other drama on top, most people probably couldn't afford rubber - which may be the point... Just a inkling. It sounds pretty outlandish, but you never know! Or things could become alot worse, alot faster, with other catalysts. "Earth events" disrupting shipping, etc. So, it's probably better to know how to make this yourself, than to bet on buying dandelion rubber from a company.

:) I do hope you don't think I sit around doing nothing all day. I threw this up on a whim, and am baffled at how many views it got.

Really Awesome idea, plastic from cutting board is an auto lubricating plastic I will definitely try this out. maybe using some 14mm copper tubes with ciment inside :)

Challu pandey I do you have a video on this subject?

cheers :) not everyone has to like it.

no worries :) 1st: draw out a grid on your plastic cutting board that are the size of the Inside diameter of the conduit + the thickness of the hole saw blade. 2nd: draw a 'X' connecting the 4 points of the square to find the middle. 3rd: drill a hole (with a drill press) in the middle of the 'X' that is the size of the shaft it needs to slide over. 4th: using a hole saw (also in a drill press) drill using the outside box as a guideline. 5th: because of the heat of the hole saw, it will leave a ridge on the piece that you just drilled out. if you place this piece on the end of a short piece of conduit, this ridge will stop it falling in, AND it will allow you to move it around a bit so that you can make sure it's centered properly (I just kept tweaking it until it slid smoothly) before gluing it into place. (the ridge will also give more surface area to apply glue) let me know if this was clear enough, or if I should make another video that shows it a bit more clearly :)

Great!... very clear!... I got all the steps... tks for your time...

@@evilplaguedoctor5158 Thank you a lot :)

Thank you very much! though I think I'll make the next one shorted based off some feedback I got.

I was indeed thinking that myself when editing this video, at the very least some que cards. Thank you for your input! (Though I doubt I'll be as good as this old tony though, but it's something to strive for :) )

lmao I'm surprised someone actually watched the other video's on my channel :p The Quinpy is in a box in a shed in the backyard of my parent's place :p no one showed interest in it, and my mind got focused on other things. that being said though, it is one of the things I may do for my final assignment for school. Thank you for asking!

I just found the eevblog thread you created and got onto here. Good to hear that the project might see a finish.

But that's no fun!

I ended up buying a cnc mill since I had issues with it binding, and additional headache's of the resin I used in other parts of the build wouldn't hold. however, I do plan to make more video's shortly that is going to be a series dubbed 'from rocks to rockets' or something, where I go from no knowledge, no anything and build up to advanced science and manufacturing. I've just about written the first script for the first episode.

Great! I'll keep an eye for it, My son in law is into model rockets an he is increasingly curious to make parts and stuff. Me I want to work from home using my cnc router and make a living.

Kevin OConnell sure thing! though I won't get to rocketry for a while, making a living off the cnc is definitely possible. :)

de nada, glad you enjoyed it.

+mataz farouh I didn't use any anti backlash nuts myself, I found it wasn't needed for what I needed it for. but I've got a week off school now, so I'll give it some thought. I'll let you know if I think of something.

I just glued a cm of flexible tubing between two nuts around the rod with a little bit of pressure. works just fine for me, but i cant tell how long it will take it to break :)

+mataz farouh Just came across this video and it reminded me of your comment, have you checked this out? ua-cam.com/video/EVW7Q469RnA/v-deo.html

thank you man,very kind of you!!

mataz farouh any time :)

Drone Girl Thank you very much! Greetings to you as well from Canada! the Q500 is indeed a nice quad copter. your video's seem very nice, with good piloting skills :)

it'll be a while before I get to that stage (just look at all the delay's already :p) but yes, since I want this to be open to the community, giving tutorials on how to make games for this will of course be on the agenda. but I foresee a lot of complications before I get to that part.
