Project Hercules Chopper Build
Project Hercules Chopper Build
Random vids on making a chopper! First the engine, made from a few bits left over from a Bristol Hercules aircraft engine.
Next up the gearbox, with no actual gears but two speeds. Intrigued? Best get watching then!
Plus a few bonus CNC conversion threads...

Induction starter from a car will do this job..
To get the giunk off the screws, throw them in the freezer overnight, first.
@@andrerousseau5730 ooh, that's a new one. I'll try that next time. Works with chewing gum apparently.
Watching this video at my workplace. The sounds were deceptive and raised a lot of eyebrows 😂😂😂
I notice that the entire choke is open to the atmosphere on your dellorto . There's an air passage way (on the engine side of the slide ) that allows air into the motor even with the throttle slide closed , would make for poor starting and low speed running .
something that might be cool and work well is a Air starter
how does it unit manage to lubricate against the cylinder wall due to the movement of a lining as valve i would love to be educate on that , thank you
@@adolfyoung4367 the sleeve is splash lubricated at the bottom where it touches the contraction ring. It's the only place where the outside of the sleeve touches the barrel.
@@StoneEng great but looking at the power unit , it has a cylinder head and piston. The head which I believed it’s has been design by the aluminum at your own knowledge , it’s contains rings to maintain the pressure for power stroke , now another question is , how does the lubricant reach TDC to reduce frictions
For what it's worth my vote would be cartridge start cool as and bad ass all in one. Excellent build and top rate engineering 👏 👍
Hmm, cartridge start? 🤔
Why don't you try to use a hall ignition sensor(three pins active sensor) for your ignition? You should get a good signal from zero rpm. I don't know if your ignition module will support such a sensor, but should be easy enought to find a module that works with a hall sensor instead of a variable reluctance sensor.
Thanks for the suggestion. I'll 'contact' (haha, see what I did there?) Boyer and do some more research.
Back in the early 80s we were using Hall sensors to monitor the cranking speed of experimental engines, it does work well. They are a little fragile and this was our problem - fitters destroying expensive sensors, usually by pulling on the leads. However this is one case where old fashioned coil and interrupter ignition works even better. If the spark can be retarded to a little after TDC you can guarantee no kick back. And you can time it with an Avometer. Old fashioned coil ignition has problems with vibration and high rpm but I doubt this engine is going much over a couple of thousand rpm.
@@Turnipstalk I am an automotive sparky. Nowadays, hall sensors are quite sturdy and inexpensive. While a coil and interruptor has the advantage of being very simple, a good electronic ignition module coupled with a hall sensor, can be very easy to adjust/ tune and can also be very reliable. Also the spark can be triggered with a simple micro switch connected on the signal output pin of the hall sensor. This can be used for starting the engine by rotating it after TDC, squirting some fuel into the cylinder and triggering the spark.
Wouldn't a strobe timing light show you when the spark was happening? Film the process and view in slow motion mode?
Yes, we've had the strobe out and while it's a good indicator, not 100% reliable. We also tried slow motion filming the plug itself. Probably needs a few people around to co-ordinate, which I haven't had due a while.
Wonder if it would start by being fired off with a shot of fuel and a spark like modern cars with auto stop/start do? Mind you a cartridge start (field Marshal) would be cool too.
Both good options. We can certainly get fuel in via the decompressor. I'll see if the ignition can be set to manually fire the coils.. Would be a cool start button. 😊 Cartridge start also being considered, but a few problems associated with that.
Sounds like a Biggs & Strappin lawnmower 😂
Perhaps this might be helpful with the starter: Lanz tractors featured 1- cylinder engines of up to a good 10 l of displacement and hence proved to be a challenge for starters. I believe the company first used regular starters on 24 V and then switched to a version which was less of a challenge re electricity and weight: a „pendulum“ type starter which would rock the crankshaft back and forth until it was able to overcome the top dead center. It was controlled by a set of solenoids…nothing fancy. FYI here is a link - maybe it helps. kzread.info/dash/bejne/nXakk9x7nKirebQ.htmlsi=VsCNUv-3ngkt26fG
@@sodium35mg that's very interesting, thank you. 😁
My dad used to say Harley's shook themselves apart. Glad to see someone given them some competition!
Any problems with wear?
Allan Milliard called he wants 2 engines
Last week, me and a bloke put to together a Vulcan 400 with straight pipes.the noise in the shed when we started it was deafening. But now i saw this beast, id say it was rather quiet...😂😂😂 Great job there!
Kickstart on that thing, backfire would send you to the orbit
😂
i bet a balance shaft would make it rideable
очень хорошо но надо было делать v-твин (very good, but it was necessary to make a v-twin) :)
Why don't you use a starter from a car? There are small ones that are 2.2 KW, that should be enough
@@peterolson8350 in the later videos we try that, but even a 2.1kw car starter motor isn't enough.
@@StoneEngEven with a gear ratio of 10:1?
I hate to be thick, but is engine a 2 stroke?
Keep up the great works.
Violent for ears 😂😂😂
Very clever
Can i ask why does the intake point . The other side air would go i side easier no ? Bmw do this to since forever
@@olgacoupal-bergeron7633 I think you mean could the intake be fitted the other way round, so that the carb faced forwards? I haven't tried it but it might be reversible. I just thought it would look better this way round.
@StoneEng exactly what I mean yes . Thank you for the awnser .
Iam a fan of the idea . Better ? The same but diesel , pro charged
Maybe you need an amal monobloc? 😅
Choppers a so gay.. if you want more gay....out a Harley motor in it !!!!
The flywheel is not very light for such a large cylinder is not able to idle
Great achievement guys! Hate to be living next door tho 😂
You had gave me this link to check out your lathe . I was always told to always buy old lathes cause they were built with quality. Very nice lathe !!
Eardrum blaster😂
Imagine that thing with an inertia starter
Зaeбok
Wow. Hats off to you guys. Bad ass.
What model lathe is that in the back ? What’s the name brand ? Love the bike !!!
I have a Warco and Myford in the garage. I think it's the Warco you can see most in this video. There's a video on the channel specifically about that lathe as it arrived quite recently.
@@MrPlumber27 kzread.info/dash/bejne/hIWDx6eoYpmWkZM.htmlsi=6BC2DMO1cF3eWvnz
@@StoneEng thank you so much h for taking the time to tell me the brand !! I am just getting started in machine work and i want to get a quality lathe and a quality mill machine too !! Love the bike !!
Well if you need it redone correctly give Allen milard a shout 😂 but seriously great work on unique engine
Such a beautiful piece of engineering. Im here from Facebook! Saw a short of you starting the bike. Saw how simple yet complex your engine design was, and became instantly intrigued. Glad you finally have it started!
Currently figure if could make a v4 with these.
A large version of the very simple kickstart used on the original American Cushman engines would be easy to fab given your high skill level and if desired could include an anti-kickback stop with a slipper clutch mounted to the crankshaft so starting is a safe proposition. If you prefer it be out of the way a jack shaft could put the pedal on the high side of the bike when parked.
what is this a 2 litre 2 stroke or something lol
@@tbounds4812 close. It's a 3 litre 4 stroke 💪
@@StoneEng I don’t know anything about it but it’s got a very 2 stroke looking cylinder and head design
@@StoneEng the thing is crazy
@@tbounds4812 yes.. being a sleeve valve the head is quite deep so the carb & exhaust appear lower in the barrel than normal. Lots of people think it's a 2 stroke. 😁
Охренеть У меня в серванте аж хрусталь зазвенела
Someone put a bristol Hercules slide valve cylinder on a bike?? Oh I gotta see this! Very cool gents, very cool!
Wow that thing is a beast! Very cool.
What is this I'm looking at? Guess it's time to get googlin on the internets. A hercules cylinder?
@@n1knunya903 look no further than this channel for details. It's all here 💪
Then I shall learn. Subscribed.
What kind of engine is it
That is wicked cool what an amazing piece of machinery.
Have You had any trouble with wear on the sleeve leading to leakage of the sleeve?
@@kurthammack9867 none yet.
More big carburetor
