Making a MK2 E-SHAFT for The 2 ROTOR R/C Engine! - Part 1/2
ฝัง
- เผยแพร่เมื่อ 27 ก.ย. 2024
- Last year I joined two O.S Wankel Rotary engines with success (sort of). The main problem was that I didn't include the front and rear counterweights and as result, it was vibrating like crazy. I could probablly make the corresponding modifications for the counterweights on the existing e-shaft, but it had some flaws that made it inaproppriate. First of all, it wasn't hardened, meaning increased wear from the needle bearings on the lobes
(I didn't notice any actual wear with the micrometer, just burnishing of the surfaces where the they came in contact with the needle bearings). Also, the front section of the existing e-shaft was 6mm to accomondate a front 6mm needle bearing (which I could have avoided) so this time, I made it 7mm so I could use a regular front bearing as the original O.S engine does.
Regarding the material, I used 1045 steel again, which I know it's one of the lowest in carbon content, but that's what was available in my area. It can be fully hardened in water, but it's almost sure that the part will bend or crack due to being long, slender and has features on it with many stress points. That's why I wented with quenching in oil. I still don't think it's hardened enough for this job, but I'll give it a go anyway. If the previous one held fine, this one will too.

Man... that's so cool. It really messes with your eyes after it's done and just spinning
I haven’t seen one of these since the late 2000s… and I’ve never seen one done like this in this depth and detail. Great work can’t wait to hear it run!
This dude is amazing to say the least
Watching rotory e-shafts, cam shafts and crank shafts being lathed has been one of my favorite things for some time now. 😍 Ty for this vid. The mini one your making is awesome!
Right? Watching the eccentric shaft be milled was hypnotic, it was so cool to watch!
I just hope that people that see when you are machining parts, the details that you deal with are at some points smaller than a thumb nail. You are really talented and great at what you do!
I remember way back when he was building one of his earlier engine turbos and he held the part up after it was finished and the whole turbo was like size of a 1/2$ coin it blew my mind lol
Some of the "details" if you mean tolerances are smaller than the diameter of your eyelash, makes a thumbnail seem huge
reasons why i love this channel: straight to the
point, no bullshit/fillers, quality content, next level editing and interesting
projects🤝
Джони! Это просто прекрасная задумка! Твои ролики открывают новый уровень , качество и массу идей! Добра тебе! Не болей!)
Это просто искусство.
Every day I am more surprised, with your ability to build something machined, congratulations! You have acquired knowledge in several areas.
I hope to retire and sit in my garage doing this for the rest of my life
Always a pleasure watching Johnny .
Thanks so much 👍🏻
I would love to see a quad rotor Mazda 26b R/C replica in the future!! GREAT WORK! #BRAPBRAPBRAP
Hell yea mini Mazda r26b
That 787B was such an incredible machine... the intakes alone were a work of art.
@@robbfisher2876 variable lenght geometry intake in the 90's 🤯😱
And then throw it into a scaled down 787B R/C car!
It wouldn't last long, nor will this twin rotor.
Gunna have meltdown issues.
It needs heat transfer... oil cooling the best, but how when the rotors are not hollow and the crank is too small to accommodate a sufficiently sized hole through the middle.
Water cooling the easiest.
I like how he just starts machining without any single word.
It is so incredibly satisfying to see someone with consummate machining skill creating intricate parts out of raw material.
This is bloody awesome! Can't wait to see it run! Remember rotaries love flowing alot of air, make your intake and exhaust with this in mind =P
Square cube law dictates that this engine has way more surface to volume area and therefore intake area to chamber volume area then the same engines scaled up to say the proportions of the 13b. This means it can flow way more air but usually also means a verry high idle.
Notice gang here
you are an animal with the machining, so bad ass watching you build that part
2rotor turbo. 10 years in the Future this man will mill himself an rc Dyno and will be ECU master tuner
When we are gonna see 4 rotary engine? 😅
Edit: Surprised that I got a love from you 🔥
Finnaly rotary engine!! Love you making these videos
Sooo good to see you getting so much use out of that micro 5-axis. You've even dialed in how to cut some serious materials without blowing it apart! So good to see. :)
Watching those lobes hover in space while the rest of the shaft spins eccentrically around is mesmerising
JohnnyQ90, for hardening this steel part.. You could follow the knife hardening path. At least for high carbon steel like 1095. First perform a neutralizing of baking at 400 F for 2 hours then let air-cool in the kiln overnight. The important part is to let the part slowly cool which affects the grain structure, do not rush it. Look up the this metal melting point and then heat to a few hundred degrees under and quench in canola oil. This will make the part crazy strong but brittle. You can also bake after quenching at a few hundred degrees for a few cycles which will soften up the metal a little bit again and release internal stresses. I cant remember where i saw it but some data exists of quenching steel using different mediums such as water, motor oil, etc. Canola oil always seemed to give the best results. Hope this helps. I love watching your projects, you are a super talented machinist.
I’ve been looking forward to seeing this build again
That rain in the background in some of the shots are pure ASMR for me, I love it.
Looks promising, regarding the hardness it could have been to slow of a quench although it's a small part.
1045 gets the maximum hardness with a water or brine quench however it probably does need to be tempered back at that point.
I can tell you are using a lot of precision. Material supports, turning between centers, taking extra steps to not load the material too much
Super professional job bro ❤️
When a video starts with a lathe getting switched on … that feels like opening a present as a kid.
It must feel a bit like a god of the mechanical realm to be able to design, engineer, machine tool all parts and correct any step of the production in an internal combustion engine as beautiful as the Wankel is. You are very skilled. Your video is extremely satisfying to watch. Imagine how many kids are being inspired! Keep up the great work Johnny Q. My dad was also a gifted machinist and mechanic. By the way, you could easily be hired by any of the Wankel Rotary engine custom builders in America, UK and Australia. TH-cam has great vids about their output. Cheers!
Beautiful work. You've progressed a lot over the years, it has been really nice to follow!
I’m a big rotor head from way back owned a few RX7’s in my day. I’m sure at some point I bought one of the first Winkel engine that O.S. Offered for the RC market in the US. It performed well but the fuel economy suffered. And the power and fuel duration I got out of a regular reciprocating engine was just a little easier on the budget. But a great piece of engineering. Awesome work love all your videos!!
I love that you are turning between centers. I don't see enough of that on TH-cam
i am speechless with the engineering quality and big brain thinking problem solving you do in this all
Wow! Grinding finished looks terrific. Great improvement.
Oftentimes when I watch your videos I ask myself, "Jesus is there anything this insanely talented guy can't build?!" I love your channel brother! Have a blessed 2022!
So glad to see the rotary engine again. Its gonna be awesome to see it run again.
One day I look forward to have your knowledge and manufacture everything I’ll always dreamed of. Thanks for being an inspiration!
Finally somethin Amazing to watch on YT !! Ty my Friend.
👍👍😎💨
I'm not sure how much that squeaking noise means chatter on this kind of lathe but you can dampen that with some rubber attached to the shaft, such as winding some rubber bands around it to make a ball of rubber on the longer end or by making a mass damper for the tool holder from castable rubber and a lump of metal as a weight. When machining brake drums and rotors the lathe has a lead weighted rubber band that wraps around the part to dampen it from chatter to get a really smooth cut. We also use a round bit instead of a pointed bit which also chatters less too.
The completed eccentric shaft spinning on the lathe melted my brain.
I could watch this guy all day :)
Surface finish after grinding looks surprisingly good.
If the rotors are 180 degrees from one another, why do you need counterweights? The single rotor version required it because the rotor was off center. With two rotors 180 degrees between them, the offset each other's weight. I think two would be perfectly balanced.
Yes!! Finally more rotary content
Love everthing you do stoked for todays rotary there my favorite engines so thanks but im holding out for that custom 3 rotor Godzilla your going to make 🤘😉
Your machining is mesmerising.
It’s funny watching the offsets it looks so wobbly and wrong but then it comes out perfect.
Superb machining! Always a joy to see you at work!
4:46 is absolutely hypnotic
Amazing work as always Johnny!
This will be a great engine 👌
Once it is running, it will be time for a 4 rotor version 😍
Btw do you have a vew tips on using the lathe and getting accurate reesults? im working on a school project and we are making a vice from scratch ant right now we are turning the main bolt
Johnny Q 90 back at it again making his little gadgets
Once this one is perfected I can't wait to see you do a 3 rotor version, or perhaps even a 4 rotor!
This guys is beyond incredible. Just magnificent work you do. Always a pleasure to watch you do your thing!
That is so cool mate! Excellent craftsmanship.
Sacrificed moms handbag to protect the lathe from abrasive dust, nice.
I never get tired of your videos, they are AMAZING!
Tool post grinders are friggin awesome, it's amazing how fine a cut you can make with them in the hardest of metals, even carbide if you have the wheels for it, and the surface finishes, especially with a finer wheel and slow cut, can be mirror smooth and the accuracy limited only by the straightness of your ways. They're one of my favorite tools on a lathe, probably the equivalent of a rotary table for a mill lol.
Excellent surface finish on the grinding. I'm also pleased to see how well the heat treatment turned out. Well done! I look forward to the next one.
Sick bro !!! Never give up on the Rotary Engine ✊
Mini Rotary, I love it! I kinda want one now...
Omg the satisfaction at 3:44 is unreal
Great video! I can't wait to see what insane projects you'll be doing in just a few years. Your skills and abilities are clearly growing exponentially.
love the channel! your content always has me waiting for the next video!
I always wonder what people this talented could do with even better equipment, like say, a 6-axis cnc....
This is wildly impressive 👏 👌 fantastic workmanship
Love everything you worked on.. all the best
All along this has been a concept now it’s reality
That’s some fine machining there.
excellent engine performance
😇
JQ90: makes the e-shafts
The lathe: *braps in rotary*
Can't wait , so excited to see and hear it running
Somewhere Rob Dahm just got a tingle up his spine
i have ben waiting for this video to drop ever since i saw v1 of the engine
finally rotary engine builds again. :-D
Im a machinist, for my part time gig we do Xometry work. I was pressured into taking a cam shaft job because it was "cool" 50 mini cam shafts, made out of aluminum on the rotory 4th axis. Then they said they accidently specified the wrong material and wanted stainless. I refused and won't ever do cam shafts again. They are not fun.
Superb craftsmanship as usual! Very impressive indeed.
Nice to see you back. Keep up the up the good work.
So much done, so much to come. Lovely work.
Great learning experience 👌
Rob.. Rob Dahm is that you??? Lol awesome work dude! 👍👍👍
Your videos is awesome 👏 but your working skills is amazing really congratulations 👏
Can’t wait for the next part
Finally missed that engine so much.
@@jeryhamna2687 sorry but why did you type that here?i dont understand can you explain please
@@amirbasssystem It's a porn bot, just report them as porn and eventually they will be banned.
@@bgood2010 thx man that was disturbing to be honest.
@@amirbasssystem Yes, they are extremely annoying.
@@bgood2010 yea it totally messed with my vibe on this video.
You are a virtuoso, wonderful work ! 👍
Thanks for more rotary content!!!
Love your approach and methodology. I wonder if it would be worth it to nikasil the cam lobes.
Love your content, thank you.
The Fireball Tool channel has a cool video on an oil wiper for the lathe that you might benefit from.
I really needa get me some micro stuff like this! Haha
Love your videos!
Can't wait to hear this in action!
A work of Art. Superb.
now you gotta make a mini version of Rob Dahm's 4 rotor
Awesome job with an hobbyist parallel lathe ! Anyway, you should have annealed the shaft after the quenching (oil was a good idea), else it may crack or break when on duty.
Always awesome to watch your efforts.
Absolute best youtube channel!!!
お見事！！
同じ作り手として感動すら覚えました。
Rob Damn would be proud
Why can't I double like? Amazing work, can't wait for part 2!
7:40 dude, you need to bake the product at 240 degrees for a few hours to relieve internal tensions, otherwise cracks may occur.
Johnny. Do you need the counterweight on the engine?
Originally when it was a single lobe it needed it, but as it's now a twin lobe and they're 180° away from each other is it needed? What is it countering?
Rob Dahm would love this!
