Take the broken old motor, core the old shaft out, and put a new, BIGGER, one in. The motor is fine, it's the junk shaft that broke. No reason to throw it away when you have a lathe + CNC setup.
yes, please do this. most motors of this size actually have a decent sized shaft inside the motor that is then necked down to a smaller size for the pinion. it would also be interesting if you could heat treat the new shaft for strength
That shaft is probably pressed into a neodynium magnet, so if he can get it out without breaking the magnet... It would be better to use an external starter unit. Have a hand held motor and battery unit with an output shaft that interfaces with a drive on the crank or flywheel. HPI Shaft start style (lots of racing cars use this style of starter too). This would provide a large weight reduction to the car as well.
Maybe those rods are the chinesium that everyone is talking about. Melting point is only 480C so it has something more than just some aluminum into it.
Just found your channel yesterday. I'm not an RC guy at all, but I am fascinated with mechanical things since I was a kid in the 1970's-80's and worked as a machinist for a short time making parts for agricultural equipment. Ever since then I've had an interest in machining, and the equipment you are using is really interesting to me as well. I dig seeing people doing the things that they love, so you're bringing a lot to the platform for me to enjoy, and probably learn a few things along the way. Thanks for that and keep it up!

To bend thin walled small dia tubing, I fill it with tin, then form it as needed like I would form a rod and finally melt out the tin again. Works well with tin solder
Love the attention to detail , cleaning the welds and rounding stuff off doesnt take much longer but results are 400% better . Love watching your work , propper tradie right there
Just wanted to point out, it doesn't help the content creators at all, if everybody would blindly hit the like button of all their videos. Watch the video, then like it or dislike it so the creator knows in which direction her/his videos will have to go.
Great vidéo again!! The assembly of both parts is done by soldering, not welding though (during welding, both parts to be assembled metals are also melted, not during soldering). Great engineering and video editing, thanks for sharing!!
Hey Johnny! When this amazing build is all done i hope you consider doing a crazy RC boat build! Maybe with that little wankle! Keep up the great work!
In a future upload: " I noticed the engine didn't have much power at higher rpm...so anyway I build VTEC for it lmao. Smol engine go BAAAAAAAAAAAHH " LOVE THIS PROJECT DUDE!!!
Brushless is far easier, faster, and so many other advantages, but you can’t beat that sound and smell!!!!!! When I have a bad day with nitro trucks I always want to throw in the towel and go brushless, just feels more real with a proper engine
1:58 there's a trick used in musical instrument making, specially brass instruments, to bend the pipes: they fill the pipe with water and soap, and then freeze it, or some kind of hot wax that then solidifies. The rigitdity of the ice prevents the pipe from beeing kinked, and the bubbles from the foam give it some allowance to move. Check here: ruclips.net/video/uIqDhO1iddo/видео.html (4:56). In that example they use some sort of soft metal. Here (ruclips.net/video/_eoGFpAiaoc/видео.html) they do it with some sort of pitch/hot wax.
Hey Johnny, I don't know if you are going to read this but you should try to do a intake mani as old bmw ohc engines had in the 80s. It's some kind of equal lenght tubes so the air to each cyl runs the almost same distance from the throttle body . Cheers.
Brass instruments are shaped with thin walled tubing filled with ice. They actually fill the tubes with water. Freeze them. Then do the bends to make sure the tubes don't collapse. Worth a try if you need to do that again.
4:11 Video idea: Make tools that are more comfortable, with more clearance for your fingers. Just a thought. I like everything you film, so I'd like this as well. 😁
Johnny Q whenever you made that new intake manifold it looked like a supercharger inlet on my man he should so make like a supercharger that sits on top of the motor either than that one that you attempted to make a long time ago when man that be so cool on that v4 engine I really hope you take this into consideration and use it for a future project
Having seen hurco tool station cncs and older bridge port interact 2s, this pocket nc makes me happy. Seems a great bit of kit. Needs to be called the k9 intake as looks like one.
I thought about the amount of overhung load on that motor shaft when you made the pully. Also, you can get solder for aluminum on amazon. I have used it many times when I don't want to tig weld something. If everything is super clean it works well.
For bending pipe like that I would recommend a low melting temp metal like say gallium or lead and fill the pipe with it then bend it, it will kink way less and you can melt the core out afterwards
I love that Pocket CNC, but what's with the chatter? It definitely seems accurate enough to get better finishing results. I use those aluminum sticks often and they work great. As I'm sure you noticed, you've gotta get the base material quite hot. It's more of a soldering/brazing technique, letting the base material melt the rod rather than the torch. Using a torch with a fine tip would be much more beneficial.
Thoughts on the intake.. 1.Three 90 degree bends are less then optimal for feeding the cylinders. 2.The air will need to make an 180 degree bend feed the cylinder below the carb... 3. The decreased air velocity will reduce engine power. I would recommend looking at how v8 plenums as an example.
Johhny love the channel mate, such skill on such a minute level, ive been following this build for a while now and cant wait to see the finished product. I've zero CNC experience but might I reccomend a mini rothenberger oxy acetylene torch for brazing the little parts i think it would help you concentrate the heat !!
You my Friend always amaze me n give me inspiration for what we can do n make for RC Everything. 👌😎 God Bless n Godspeed to you buddy. Stay safe n yr loved one's RC4LIFE 👍👍😎😀💙
I highly doubt the rear cylinders barely breathed. The most likely chance is if 2 cylinders had an intake stroke at the same time, but if you were worried about it, all you would have to do is make sure air is coming from top, not front. The only thing changed with the manifold is the resonance (due to different length runners). Lovely build non-the-less! 😀
John, seem like you need a little more torque on that starter motor. My suggestion if you chose to accept it is to use some pinion gear with another spur to get a higher mechanical advantage. Since your using a brushless, you have the speed and you know that in-runners have more speed than torque. You can switch to an out-runner which have more torque than speed but only will know if that would work in this application. Thanks my Two Cents. Great video and thumbs up. Keep safe - from Brooklyn NY.
was hoping you were gona bust out the tig and do some tiny welding (tiny welding is cool af) but to get the results you did with the alumiweld, youd have be a pretty good tig welder. After puting the work in the alumiweld turned out just fine.:3
I assume he does this full time... The amount of time you need to do these kind of projects with such high quality is insane. I think about it all the time when I record my projects. This kind of "RUclipsrs" work A LOT 💪
@@EliteWorm That would make sense too. Most RUclipsrs can provide a living from making videos when they pass 400-500K subscribers, Johnny has 1 million which should be sufficient to provide a living :) Although, definitely an engineering background cause his skills is not something you just find in the back of your pocket ;)
@@sebbelito2975 Engineering background not necessarily (but likely). He definitely has some kind of background working in or around machining if nothing else.
Still going to be getting uneven flow, a crossflow dual-carb setup would be cool. Basically the same as what you've got, but with another carbointed opposite the one you have now.
William Apodaca yes, but that would require a 180 degrees turn in the back carburettor's air inlet tube, which is a problem for two reasons: -he is unable to make such a tube -it would mean that the cack carburettor would get less air, so it would still be uneven A a flow disturber (like a steel grid) put into the start of the manifold would be way easier to implement, and would be much more effective.
This alumnium part actually turned great !!! For the starter motor you need a higher torque motor but it will probaly have a bigger diameter. When it comes to BLDC motor diamerter is often linked to torque and lenght to RPM. Find a low KV rated motor. Keep up with the great work man
I imagine this engine with a twin screw supercharger and a scoop to de carburetor breath fresh air *-*
I was thinking 4 carb crossram with 4 inch runners to increase torque.
a supercharger wont work on such a small engine sadly
@@FrmerK20 what about a centrifugal supercharger?
@@someguyontheinternet5944 Johnny already tried that but couldnt achieve high enough rpms to make any boost. It was just a fan.
@@FrmerK20 Turbo anyone??

@@bradcomis1066 All depends if being able to start it remotely with the body on is a priority.
@@themadscientest why? and you can also start it from the bottom
I believe you are aluminum brazing, as you are not melting the parent metal. You would need a TIG welder to actually weld aluminum.
jp this is brazing not welding. I recommend next time use some flux for aluminum.
I only know this because of this old tony
Maybe those rods are the chinesium that everyone is talking about. Melting point is only 480C so it has something more than just some aluminum into it.
Actually you can weld aluminum with oxygen and acetylene. TIG just happens to be more efficient.
No flux in aluminum brazing but ya do need to get the oxidation off a bit.

It's always great when you can make your own parts. Great engineering skills
You could make a cool hybrid setup with the engine and starter, just how the starter seems to be more powerful than the engine

try tig welding for welding aluminium comes out really nice once u get used to it
Why won't u make a little turbo for that tho?! I wanna see a little turbo

Unbelievable man u r genius 👍👍👍
It's always nice Johnny, to see one of your videos, especially when the state confines everyone at home because of the Covid-19 (☣️)‼️😉👍🇨🇵
I admit that I'm curious as to why you didn't try a dual carb setup, offset front and rear slightly to keep the height profile down?
Amazing job mate!!
Thoughts on the intake.. 1.Three 90 degree bends are less then optimal for feeding the cylinders. 2.The air will need to make an 180 degree bend feed the cylinder below the carb... 3. The decreased air velocity will reduce engine power. I would recommend looking at how v8 plenums as an example.
Great job!
I love your damn videos. Very creative and efficient..👍
Did you try filling the tubing with an incompressible medium, like fine sand or oil, and sealing off the ends before bending it?
Wow, very good video!
are the shafts for the start motor an appropriate material? I am surprised that there would be enough power to shear it
I thought you were going to tig weld them, was not expecting a torch and aluminum sticks.
Still a good mechanical bond, but the base metal wasn't melted. Low temp braze or high temp solder. Either way, it wan't welding.
Cant wait to see it running more! Did you use flux for the welding? It seemed more like solder and for solder flux helps it flow a lot
Very cool... top job!!!
