In this Video I explain my motivation and the steps I took to make my idea for a 60 degree V Twin minibike engine and make it into running prototype. The engine was designed by myself in Fusion360 using a mixture of off the shelf parts and one off components. Once my design was complete I used the lost foam casting process to turn my foam patterns into a solid aluminium crankcase. The next step was to use Fusion360's CAM to create all of the G code, this allowed me to CNC machine all of the important features on my Converted Optimum CNC mill. Once everything was machined, it was time to fit it all toget...

Go to jlccnc.com/?from=nodds for all your custom manufacturing needs. In today's video after a quick re-cap on how I lost foam cast the crankcase, I machine all of the critical dimensions on the master con-rod using my boring head on my CNC milling machine. I also press in bronze bushes and ream them to final size. I then dummy assemble the engine with 3D printed intake manifolds. Completion is...
Machining a Conrod for the Retro V-Twin
Просмотров 6 тыс.3 месяца назад
In today's Video I show you how I machined a connecting rod for my lost foam cast V Twin engine on my converted CNC Mill. The conrod is made from 1045 hot rolled steel and will run bronze bushings in the small ends. I designed and programmed the part in Fusion 360 before machining it from 25x25mm square stock. The rod weighs 100 grams making it lighter than a stock Lifan pit bike conrod by 14 g...

In this weeks video we check out my V4 350cc 2 stroke patterns before looking at the progress on the retro V-Twin engine. I cover the lost foam casting and then the machining required to take the castings to an almost finished state. All of the CNC milling is done on my converted Optimum MH-28V mill running on Mach 3, all the CAD and CAM is done using Fusion 360. Make sure to like the video and...
Lost Foam Casting a Retro V-Twin
Просмотров 9 тыс.6 месяцев назад
In this video I test out a CNC Router and make a pattern for a new V-Twin engine. This is so I can make sure the CNC router is tuned well enough not to make a mess of my XPS foam and make accurate patterns for the V4 rear crankcase half. I then attempt to cast the pattern, the first attempt was a failure and the second attempt went perfectly. All the CAD/CAM was done in fusion360

Here's a random video of me repairing a BS-7DS band-saw I bought cheap a few months ago to flick for a tidy little profit. These little money makers help fund the V4 project. . . and my Land Rover money pit. It involved removing busted bearings in a creative manner and giving it an overall tidy up. Facebook market place always seems to have deals like this going cheap. Make sure to like the vid...
Lost Foam Casting - V4 2 Stroke
Просмотров 6 тыс.9 месяцев назад
In this video I show off my new 'Test' casting which was lost foam cast. I also give a brief run down of the engine design and explain what is next for my V4 2 stroke GP motor build. The next step is to get some more casting supplies together and head to the foundry to have the gearbox cassette plate and the front crankcase half cast. After that I will machine the foam pattern for the rear cran...

DIY 144cc V-Twin, A Better Tensioner
Very interesting. Great work. I am only on steam engines. Have a lot to learn still, but would love to build bigger and more complex engines. This is inspiring. Thanks. The engine looks and sounds great. Wow
Thank you, the sound ended up better than I could have imagined.
Отличный результат! Вдохновляет.
Great work,pretty cool.
When I did work on my Harley I had to take the exhaust off and I too heard the magical bubble machine sounds. You just don't associate that sound with something powered by combustion.
Im glad it’s not just my little engine that makes those noises.
👍👍👍
I dig all the random highlighted projects you stage your monologues on…
That is so cool! I need!
Master!
Wow, you're the man! Will these be for sale so we can put them in our own projects?!
Thank you. I’m not into marketing or dealing with customers so I will be selling these exclusively to Tim (hustler minibikes) and he will be selling these either on their own or in bikes. Contact him if you’re interested.
Well done, a massive achievement, i must say when i saw your crankcase casting i thought the foot type mount was an odd choice for a motorcycle engine but now it makes sense, Your video making is quite impressive as well
Thank you.
Now if you could cast a mirrored head. Allowing the use of a single carburetor , and the exhaust to rear exit on the rear cylinder. This is awesome! Imagine a short block, with the ability to use two Suzuki DR 650 cylinders! A roughly 1300 cc engine. Anything from 900cc to 1400cc-1500 cc😮. In theory, I'm thinking around 1200 would be better, 1180's-1190's cc displacement. Making power a bit higher in the rev range. Make it a bit safer on a mini bike.. a slightly lower bottom end tq! Maybe make replica air craft cylinders at or greater than 2000cc per cylinder, with a 5"-6" bore, like the liberty engine maybe make it a bit more modern shorter stroke , lighter piston. 4340 rods and crank. Cast a light weight piston using old pistons add some more silicon, make a good hypereutectic piston alloy. HD and long rods , get a roughly 8:1 compression, a 4"stroke with a 6" bore, use two 1.95"- 2.0" exhaust valves, two 2.100" intake valve use a custom cam grind made from tool steel with adjustable followers around .600" lift 280° 235-240 @ .050" with 300° on the exhaust use two 38mm carbs, on a plenum that bolts between cylinders. Using safety wire. Use one for idle the second opens at 1/4 throttle. With the pistons having a large dish hemisphere shaped directly under the sparkplug with smooth grooves around the edges to allow the air/fuel to swirl when the piston is reaching tdc. Use bevel gears to drive the cams. Off a 20 tooth sprocket driving a 40 tooth sprocket on a shaft with bevel gears and a oil pump driven from the far end. And a "distributor" on the near end. Actually a dual cdi looking like a distributor. A rotor with two metal bits for the pickups to read, one pickup mounted 1/2" higher than the other so the get their own separate ignition times. Looking like a old style magneto or distributor. With the cdi output going through beaded conduit, to the cylinder tops with a motorcycle coil mounted on the spark plugs the cam covers having fins to appear as a sleeve valve engine. Then scale this down with a 4"bore and 4" stroke for a mini bike , or even a smaller 3.25" bore and 3" stroke using two valves, 1.5" 1.25" intake /exhaust. A 30 mm carburator, have a mini block, small block normal block, then the big block! Sell them as kits finished castings that can require final machine work. If I had a shop with equipment I'd make one hopefully sell them! Definitely build one! ✌️ Awesome work
Thank you, it sounds like you’ve put a decent amount of thought into this. It sounds like it would be a good project to model in 3D.
It sounds more like bubbleboat bubbleboat than potato potato
I have a JAP 60deg V twin on my 1934 Morgan three wheeler, and I love this little sibling. I can't actually comprehend 'just' building an engine - top marks for the engineering and balls to just do it!
Awesome watch. Even more satisfying to learn the process after seeing the comments in Tim's videos saying it's AI or fake sound. 😂
Thank you. When I saw those comments I had a little laugh myself.
Great work! The engine looks awesome!
I want one, how much lol
You’ll have to flick Tim a message as I am not going to be personally selling this particular motor.
My question is why use a linked rod and not two separate rods, wouldn’t it be cheaper to use the rods from the single cylinders?
Other than the fact it makes it unique and my own engine. It would mean a new 3 piece crank which needs machining, hardening and grinding. . . Not to mention the Honda rods are far too short for the narrow V angle.
@@OddsandEndsMachining im pretty sure these are the motors le dan likes to use ... in that case you can press the crank apart and combine 2.
ruclips.net/video/GkMEvM0-JAU/видео.html
Thanks for taking an interest. The are more considerations to take into account than are apparent when you view this from the perspective of comparing what I am doing to Le Dan. That would need to be the subject of an entire video on its own. I think there is a difference between making a one off for a video and making something that can be sold and will run reliably.
easier to make the rods proprietary and use a common gx200 crank
Well done Jonny. Again, I'm impressed. I'll be in touch soon for a catch-up. Andy
Thanks Andy, sounds good.
I love everything about this!! Amazing Craftsmanship!
Thank you
how to make smooth surface on casting
Check out the video on how I cast the engine. If the pattern is smooth the casting will come out fairly smooth. You can sand and media blast them for an ever smoother surface.
That's a mini bike you would ride, not just a lawnmower engine with two wheels.
Hopefully it goes as good as it sounds with the in bike testing.
Nice series IIA 109. What year is it?
1967, it’s almost ready for a WOF, it has a Holden 202 swapped into it.
@OddsandEndsMachining WOF? Not familiar.
@@scienceaddict77 ‘warrant of fitness’ an inspection required 6 monthly for all vehicles older than 2000 in New Zealand.
Amazing. Saw the startup on Instagram and my jaw actually dropped haha. Stunning work, it sounds great
Thanks. The fact it sounded so good was icing on the cake.
This is absolutely awesome! I’m not interested in the machining, as I’m a carpenter, but I love mini bikes! I’m building my seventh right now. (I got me some kids…🤪) I would straight choke a man to get one of those engines to Michigan! It’s amazing to me the knowledge it takes to create an engine from scratch. And you wield it like a seasoned professional! New Sub!👍🏻
Thank you
Been watching you a while now, Fantastic to here you're from Palmy. Im just outta town, towards Newbury. Small world man
What's it going into?
Check out hustler minibikes. At least the first ones will be going into minibikes
Finally!
Awesome, when are you goingvto start selling kits?
You can contact Tim at hustler minibikes as we will be selling them this year.
Great job friend!👍🛠️
This is awesome!
Exciting times.. Sounds the part 👍
It sounded like a SpongeBob engine! 😅 Sounds way better after! Super impressive custom work!
I absolutely love this shit, I basically have the same CNC converted mill, I also do pitbike/minibike racing and go big bike racing from time to time... Please also share your minibike racing stuff, I love to have found someone sharing so many common interests :)
Glad you’re enjoying it, what kind of things are you making on your mill? I should upload the racing regularly, I keep putting off buying an action camera though haha.
@OddsandEndsMachining I have made some sheet metal forming tools, because I used to do that before professionally before I switched professions :) And now I do some pitbike adjustable foot pegs, tripleclamp and some other accessories.. I'm looking into fixturing some of the stuff and selling it, small scale for fun... And because I get asked a lot where I got it 😄 I'm really intrigued by your casting and engine building stuff, but I'm hesitant to put the time into designing it, just to fail after a couple of minutes or hours running 😄 After all I'm not an engine designer, and my software engineering degree won't help much there 😄 But I might try building a frame, I really loved that! It seemed quite straight forward, but I would 3D scan a minigp or buccimoto first I guess, just to get in the right ballpark regarding dimensions, and maybe put some time into some solidworks analysis, see if I can improve on the design.. For recording the racing just buy a 360 camera, insta360 X2 will do, those go quite cheap now, and it's pretty hassle free, just clamp it somewhere and forget about it 😁
You have definitely put in alot of work man hopefully itll could work out you make some good money on makeing them i do sujust better valves in them heads thin stock tho iv had a few brake an burn though on my kids small forwheelers
Thanks. This is getting a fairly safe rev limiter so hopefully we don’t run into any issues.
In italy we say: sei uno con le palle! Nice job mate
Thank you
Carrying on in the footsteps of John Britten. 👍 (hard to imagine he's been gone 30 years already)
I see you have been working on a V-twin. Any further progress on this project? Best, Kelly
Only planning at this stage, I have decided I am going to do away with the cassette gearbox (seeing as I don’t have alternate ratios anyway). The plan is to split the rear of the engine down the middle in two halves which will make them a manageable 8kg pour each and they will be far easier to gate. I feel like once I get some momentum it should all happen fairly quickly. Regards Jonny
How do you get rid of the foam before pouring the mold?
It’s in there when i pour the Metal. The heat causes it to evaporate.
Man this is cool AF
Amazing!
you need a ratcheting socket adapter
Who needs a starter motor when you've got an ay egg.
I was thinking about using someold disused motorcycle crank cases clean them up and melt into an ingot and have it cncd by the cnc crowd u use What I really want is slow expansion alloy so I don’t have to fuss to much over the brg clearances added nickle can produce that property but need more research
To me, it's seem quite fast for a short gearing 😊
Hi mate I couldn’t help but notice that that is the same cylinder and piston as a 125-140cc pitbike, if you used 125cc cylinders instead it would equate to a 250cc or if you used 140cc cylinders it would be a 280!!! I’m so exited to see what you do with this. Absolute beast mate! Much love from the UK
Thanks you, one of the upsides of keeping the piston size down is it will be slightly easier to balance and require less weight added to the crankshaft. If this runs well though I could definitely be keen to make it 250cc+
BRO, I JUST TRIED JLCCNC BEEN FINDING WHAT CNC COMPANY WILLING TO MACHINE MY CYLINDER HEAD AND IT COST FREAKING 200 DOLLARS! MAN THANK YOU! Other companies tryna chop me for $500+
I’m glad to have helped. To be honest, unless it’s simple parts or parts that require a tolerance greater than .05mm I will do a lot more outsourcing. What is the head for if you don’t mind me asking?
@@OddsandEndsMachining it's a suzuki gsx 150cc bike planning to convert it to a 300cc. I'm not happy with the bikes OEM head design and what I did was create a cylinder head with vertical ports and flow tested in simscale. Btw mate big fan of your videos. Can't wait for this 60 degree v-twin chop
@@dtb_toughbaby Awesome man I’m gonna check em
Very late to this series but love the relatable riding clips. Tinkering with the end goal of stacking it on a trail😅
That was heart breaking to hear about the length mistake. However, the extra length should benefit the torque curve somewhat with a slight sacrifice on the horsepower. Balancing the engine may be a little trickier. You never know, this may end up being a happy mistake. I think what you are doing is amazing, best to you!
Thank you, the crank actually needed quite a lot of mass added to it to achieve a 50% balance factor. Hopefully it isn’t too harsh.
JUST ADD A SPACER/SHIM TO THE BOTTOM OF THE JUGS!!!!!
spoke too soon, lol
Hey man if you are going this hard why not go for a pair of Daytona 212's
This is for the aesthetic and less about performance.
