DUDE I WANT TO GIVE YOU THE BIGGEST HI FIVE RIGHT NOW YEEEEEEESSS CONGRADULATIONS!!!!
Thanks man! 🙋♂️
High*
CongraTulations*
I love this. My friends give me a hard time when I reinvent the wheel on my projects but I believe that by going through the process of making something from scratch one can learn a great deal and make improvements on existing designs. Keep up the great work. Who knows what innovations this process will unlock?
I have been conditioned like Pavlov's dogs. The 2Stroke notification bell goes off and I stop life for this. not complaining. just realizing I may be addicted
plottwist the notification bell is two stroke engine knocking
👍😁👍
😂👍
Me tooo!! lol
I can't wait till the machining and assembly of this new cylinder starts. I'm totally lost on why your doing this and how much you think you can gain but I'm rooting for your success and that it works well. This is the kinda thing that makes me proud to be human and let's me forget about the craziness in the world right now.
Thanks!
This is The stuff most people don't really care to see. This is the stuff that is most interesting to me. Not so much on the metal casting I don't know about that but all the ports and holes and exhaust intake all that stuff is really intriguing. Thank you
There is SO much here that you cover..quickly.. Casting through cylinder design, there are a dozen video's in this alone to those who would learn. a life time of technical knowledge here, certainly this one is worth machining and be used to begin the R&D process to get things right on the actual motor...
Thanks!
Your work reminds me of when I build my first racing drone. And then with what I learned I build another one. It took months (not full time) and I learned all about frames, motors, ESCs, batteries, flight controllers, senders and receivers, cameras, OSD, FPV and more. After all was finished I started to learn flying. At least that was the plan. I never learned it because what I really wanted was build these things. It was not interesting anymore after they were finished and worked just fine...
👍 Story of my life!
You got this,I have been on the edge of my seat awaiting this to hit the milling process.I am a retired small engine mechanic and a fabricator,I have built many hot rod chainsaw's in my day and can't wait to see this come to life.
@2STROKE STUFFING Sorry to post again, rewatching this video again at home, I noticed that when you quenched the casting, in pinged, popped and made sounds that are much more than water being heated - it means it has many micro fractures and stress cooling breaks within its structural matrix.
Please do not quench cool the castings that you will be using in the engine tests - as they will not last long at all before something explosive/catastrophic happens.
Please let the casting you will use cool carefully in the cooling kiln (with the door ajar/slightly open) until it is below 200 degrees C - prefereable only air cool after it is below 150 C, if you must quench it, makes sure there is a lot of near boiling or hot boiled water to minimise the temperature differential.
It was the relatively cool/warm water that caused the audible pings, pops, and tchink sounds of the casting (micro-)fracturing.
aka porosity
I get so happy to see a video notification come up.
Looking better and better each time! Can't wait til the next one my friend!
Thanks!
This is the reason why youtube exists. You're awesome!
Thanks man!
As someone who has lung problems I have to say please get a respirator I'm sure some fumes from casting are not good plus that dust stuff you put on the tools. Might be wrong but better safe than short of breath
Yes, the casting plaster is super deadly. He is doing amazing work but has terrible health and safety practices.
He should totally.
@Dennis Young It doesn't have to be a supplied-air hood, a PAPR powered respirator will do the job. I used one for DIY grinding, sandblasting and woodwork so that I don't keep having to shave my beard off.
@Dennis Young Aluminum is a neurotoxin, it is not good for you to breathe, or eat.
@Dennis Young most of the cost in the hood you showed is in the auto lens (Speedglas™). If he is just going to be doing grinding or foundry work a fresh air sand blasting hood would be much cheaper and have a great deal more range of view. The hood you have is a very nice hood for welding.
Perseverance is the answer! I've got to hand it to you man, I've watched for a long time and you have come a long way in the right direction! Can't wait for more.
Thanks man!
Top work mate! Improving all the time, now let’s drink 🥃🥃🇦🇺
Thanks!
You might be able to mix in some glass fibers into the plaster to keep it from cracking during pouring too. You should at least do some test machining on this casting to see how they work on your design, so you can see if any further changes need to be made in the design.
Your definitely right , glass fibres mixed in with the plaster will increase its strength immensely.
Much stronger, but much harder to remove from the finished cast, also
Thanks for the tip!
If you do add glass fibre to the plaster it should be between 3% to 5% of the weight of the plaster mould
Thanks for the advice!
If you add bicarb soda to your water bath it will dissolve the plaster casting material less scraping and chance of scratching up the end product. Hope this helps looking forward to next attempt
Thanks! Others have suggested an acidic solution. Might try both.
Congrats mate, well done on a huge effort. And good on you striving for perfection.
Thanks!
This guy is really goid!!! He is quite the ingenious machinist / inventer!!!
Well thank you sir!
UPS on printer!! Yes .. FYI - there are many old APC UPS units out there with bad batteries, can be had for very cheap .. If ya know anyone who works in IT .. they usually pay to have those things disposed of ... I brought home 6 FREE used ones from work one day ... rewired them for an external plugged in car battery or high capacity garden tractor battery ... and it will run your printer and other stuff for 1/2 a day.
Firstly, this is such a massive effort, congratulations!
Secondly, throughout all of your videos, i cant recall seeing any outbursts of frustration, or anger, despite all failures/catastrophies, which is impressive. Or suspicious, not sure if your human, or 2 stroke powered machine.
Either way, kudos man! Keep killing it.
Thanks man 😁
4th times a charm. Wish i had your determination man. Good luck
Thanks! I really enjoy the process!
Congrats for keeping the 2 stroke alive...looking forward to more.
Thanks!
Hell yeah man, you'll get right, and that thing is gonna be rad. I'm gearing up to make a 122cc v twin 2 stroke myself, and this is great inspiration for that as well
Thanks!
The suspense is killing me. You are doing a better job than most can already and I want to hear this thing Roar
👍 😁 👍
Hi ALL if its 1 thing i have come to realise is its people like this man who could revolutionise the way we live and this is JUST 1 MAN IN HIS SHED can you imagine what the gov has in zero point energy, the medical applications the way we should ALL BE LIVING INSTEAD OF LIVING PAYCHECK TO PAYCHECK, People as far back as early as the begining of the 19th century had a better standard of LIVING, and here we have 1 man who working and USING CRITICAL THINKING to solve a problem i have the utmost respect for him and wish him all the success he deserves WELL DONE THAT MAN .
Thanks man!
Incredible! You are doing the most interesting build I have seen in years. Excellent! Excellent! Excellent!
not only do you spend alot of time designing and building this engine, bt the time you take to make the video is also to be commended,keep up the bloody good work
My former employer at an automotive repair shop in Oregon used to say "Make all the mistakes you want, just do not repeat them".
Right on, congratulations man. I'd say that's a major SUCCESS!
Thanks!
I just discovered this channel. I don't like 2 strokes but pistons are pistons, I hope you succeed.
That came out great! Thats prolly the most complicated homemade mold I've seen, can't wait to see it after machining!
Thanks!
Bet you can almost feel the wind in your hair riding this technical monster had a little suzuki fifty i bought for my kids everything was stock and with an adult rider it would go over 85 kmph. And wheelie in the first three gears. I think the adults had more fun with it than the kids did lol. Yes we were bad adreneline junkies but it was such a reliable machine even after the adult abuse. My neighbour bought it and his kids learned on it as well, may still be running to this day. Im sure you are anxious to get this project finished but now is the time to take even more care and not get complacent, I have fingers toes and legs crossed for success next pour will be the one and then you can take us all for a ride, peace and fortune favors the bold Ontario Canada is rooting for ya.
VERY cool, and inspirational, ROCK ON MAN. can't wait till next pour. hope the best for you.
Thanks man!
AWESOME!!!!!! still waiting for this engine to be put in the motorised bicycle (; Greetings from Germany.
Thanks!
Excellent, perseverance pays off, casting is an artform which even professionals often mess up, well done!
O Man Congratulations it must feel good seeing light at the end of the tunnel . Very Good take care God Bless.
i could sit and listen to this guys life stories for hours,providing theres plenty of beer.lol
You can fill those flaws with Aluminium Tig weld before machining.
I was gonna say just braze it with the alloy rods. It's even stronger than the aluminum. He could heat it up with one of the big boy tools and just melt the rod right in perfectly.
Stunning work. A few ideas that may be of use. You can add silica sand or glass fibre to refractory to lessen cracking. In some furnace refractory they even mix in stainless fibers for this purpose. Also on swdweeb's channel today there was an excellent video on sprues, combustion chemistry and porosity that you may find of use with such high performance casting.
FUCKK YEAAA, finaly a succes..Im soooooo glad that this casting turned out almost perfect, now I am hardly waithing for the video when the cylinder will be tested..I hope for the best
👍 😁
Great Job, its great to see the casting come out and looks good.
Sure next one will be even better, cant wait to see how this progresses
Thanks!
You're an absolute legend! So impressive. Can't wait to see where all your work and learning takes you and your project.
More better and better my friend... but i think now... it's perfectly beautiful
Congratulations on your success Mr stuffing 😁..u are one dedicated fellow ..ps I like the motto painted on your wall...very true...best wishes from Ireland...
Good job man, I can't see any flaws with your method, looks like every cylinder jug we ever cast for rotax.
Better and better each time. You're killing it dude
Thanks!
Sweet suff(ing) 🚲💨💨💨
💨👌
I've used a wet asbestos mat put over the filling hole to aid molten flow into details,steam pressurization albeit on less complicated castings but with success,I've also used half a potato!
I hope you will make it. Cant wait. You are great!
Nice job! It’s looking good :)
I had to buy a Ups backup for my music gear, I make sample based music and if Power is lost even for a second or two all my work is lost if I had not saved it, after getting a ups I never worry about that problem anymore. I’m looking forward to seeing your next video! Ps I know it’s a lot of work trying to get back to people in the comments, especially after posting a new video, it can be overwhelming sometimes.
Take care
Congratulations, I'm very happy for you and i'm impatient to see the rest.... Good luck!!!
Thanks!
Excellent job bro!!!!!! Can't wait to see the start up and run and make power!!!!!
Thanks!
Keep in mind that the pistonrings would need bridges passing that exhaust. There are rules about how wide they can be, 70% of the bore or something. Better check that out or else you are doingit over again. Wide exhausts are mean but rings chew them at every pass.
Watch the earlier vids in this series, I'm going to be using a special retained ring to (hopefully) get away with the wide exhaust port.
Congratz from France, your progress is insane !
Thanks!
Awesome job man!!! Coolest channel on the Tube. You have come so far so quickly. Can't wait for a finished piece to get a chance to actually run. Keep it up!
Thanks man!
you should try giving your 3d printed parts an acetone vapor bath before you use them for your next casting. It helps a lot with the surface finish and only takes a few minutes to do!
you are absolutely outdid ! congratulations...
Thanks!
Strong commitment brings excellent products
Nice job
Thanks!
One step at a time! And now, you are there!
Awesome!!
It's fun to see how it looks better and better 👍
Great work👏👏
Cheers from your neighbor Sweden 🍻
Thanks!
SUCCESS at last...... Cheers mate!! Hard work and deication is setting in.
Thanks!
I have seen a video where a small filter was located in the bottom of the main sprue and this kept the metal flow rate down while pouring which helped eliminate some bubbles and flaws.
Been looking for some ceramic filters.
Ya success at last.I knew it you do it.My support is always with you. #Powerful2stroke
Thanks!
Practice makes perfect 👍👍
👍
I'd melt the PLA out of that mold slower than what you're doing. It'll help with cracking/offgassing. The steel shell will also help to an extent, but it's going to be mostly about getting the mold up to temp slower than you've been doing because you have to give that chemical water someplace to go, and it takes time to remove it.
This guy is a genius. We have our Nobel prize winner.
Hey I am glad you mentioned my name , thank you ! And you really did an amazing job. Kepp it up and sure we will help you!
Thanks!
*opens the back of the furnace* "yep its fucked!" *closing*
😂
Congrats dude! Your work is pretty addictive to watch, love your work! Hope the next one will be a success. Thanks
Thanks!
Good to see the exothermic powder did its job, glad it turned up in time for the pour.
Sure did!
Awesome job man! I'm keen to see this thing run! good luck from Australia
Thanks!
You definitely deserve to have the fastest two stroke ever build. Nice work!
Wow, your doing incredible work. Chase it
Thanks!
You’ve got my like fixed. Man, awesome work!!! You and your videos are inspirational!!!
Thanks man!
MAAN! You're an inspiration to us all! You're doing a brilliant job!!
Just in one word, awesome!! Love the way you make your vlogs! 👍🏽👍🏽👍🏽👍🏽
Thanks!
I have read you can get smoother prints by having the print in acetone vapour.
For the flat part with bubbles, make the flat surface sloped if you are going to machine it anyway.
When you get it right, I suggest you make a couple of extra castings as spares. It's harder to re-do if enough time has passed. :)
Beautiful cast man. That has to feel so satisfying to see and hold that piece
Thanks!
Neat. Try tilting the mold just slightly and you might get less bubbles on the bottom.
Thanks! Good idea!
Fantastic! Congrats man, you are an inspiration!
Thanks!
I can not wait to see this cylinder run on your dyno anymore, big up bro!
Amazing. I have a couple bad lost pla castings begind me (each time the pla did not burned out).
Its nice to folow your progress!
Nice one. This is getting really close now. Large rums all round😆
You will likely find casting to be of sub par quality..... weigh it compared to a factory cylinder and you will find the home castings are much lighter/less dense. Commercial castings are done in a pressure caster, which doubles the head pressure. Use a kush device to aid in filling your mold out, and more air vents. Best of luck.
Congratz! I am so happy for you!
Thanks!
Ok looks good, hope we see it on the Dyno soon ;-)
Haha cool here in Holland I am milling so long for with those bits. Dude you are in reach of runnin the cilinder, but you need to make a piston :) and yeah I stay tuned :) like 192 deg. :)
👍
Its certainly getting there ;P kudos and continued best wishes - the mould 'sleeve' is a good idea as well as having a deeper lowest casting/mold 'sump', I think some of the gassing imperfections was from the pouring accident - faster filling = less time for the gas to escape & less smoothly filling with molt.
If the internal porting cast issues are still happening, you could make the internal bore & riser a bit smaller still, to give more waste material distance for them to occur in - as the few imperfections seem to be at and around the edges of the mould/casting.
Contiued best of l*ck and mechanical wishes, you deserve an occasional dram of rum :)
your videos are really inspirational, so much so my little twostroke honda NSR150rr came out to play, with no big power gains to left to be made on the engine as it is ported, piped and carbed, it only left me with one real option, Nitrous Oxide.
So I fitted a fuel pump, pressure regulator and a fuel injector into the carb bellmouth and about to fit a 10hp jet for the nitrous, we will see what a wet shot of nitrous does to a bit of a race two stroke
I had to pause your video @ 7:39 to find some paint and a brush to paint that message over my shop bench... It's 2300hrs here, but had to do it right away! Thanks.
bung it in an ultra sonic bath, get all that crud out
I'll shop around for a machine.
2STROKE STUFFING they have many uses i'm sure you'd find handy. Degassing, cleaning, and others. Not too expensive these days either.
@@2STROKESTUFFING eBay they are cheap, awesome units.
Nice work. Can‘t wait to see your project running 😍
Thanks!
Buy cc specialty tools for porting, those 90deg dental handpiece wont last anything and you lose your mind. Been there. Awesome work there my friend 👍
Thanks! Agree, sometimes they last a little while tho.
You are giving me the strength to rebuild my crf450, tack so javla myckett!
👍 😁
Looks great! A lot of effort. Cant wait to see the next one and have it machined!
铝水倒进磨具后，最后上面的沙子是什么东西？
Amazing work! Durafix or alumaweld May be some help as long as the jug doesn’t hit 700°F . I’ve only recently heard of this stuff and should be getting some in the mail today. Congratulations on a job well done, I can’t wait to see it running.
Could I suggest using a bore scope to check for imperfections in the inside of the engine
Congrat for great success!
Thanks!
You can apply jb weld and it will fix the holes
