Step 4: Fly wheel - Preparing the casting

  • Cut runner off casting
  • Clamp and drill Ø6.8mm hole through the centre of the casting then tap a thread at M8
  • Take a large diameter aluminium or steel rod (Ø25mm or above). Centre drill it and then drill a Ø6.8mm x 30mm hole
  • Cut the head off a M8 x 50mm bolt, file the sawn edge and put into the rod
Beautifully made! You are a craftsman.
<p>will it work if its made in a larger size</p>
<p>Maybe if you did not have access to a crucible or melted aluminum, you could use resin or epoxy in its place</p>
<p>Hi there. I've been looking for a tutorial on how to build a minni diesel engine for my year 10 science project but haven't found anything that can help me, luckily Google helped me find this tutorial. It's not diesel but I'll enjoy making it either way. Thanks so much from Wynberg Girls High school, South Africa! </p>
Nice air engine! did you try it with steam?<br> <br> <br>These is my steam engine from student project: <br><br> <br> <br><iframe frameborder="0" height="315" src="//www.youtube.com/embed/Q2ObnvYypDI" width="420"></iframe>
now make it street legal... and go 60mph
you should make the kids do everything. My grandfather tought me the lathe and vertical milling machine at age six (am 14 now) <br>
Can you tell me how the air supply is fitted, is it just a push fit? <br>Also what length, diameter and strength spring is best to use? <br> <br>Regards <br>Adrian
hi, good questions :) air supply is just push fit.....tube into the hole. a light spring is best, the nut allows adjustment of pressure.
could you please tell me the dimension thickness of the chassis this would be much apreciated
Hi, it doesn't really matter. I have made engines that have had 10mm chassis. However this design uses 5mm
what was the tickness of this plate as i cant seem to find it your help would be much apreciated
Any ideas on what else it could be used for?
anything that uses a low torque revolving motion
or use a car alternator and run it off of that to get elctrycyty
unfortunately the alternator would require more torque than the engine could generate + you would get less energy out the alternator than you put into the compressor! if you have any ideas on how to solve that issue you will quickly become the richest person in the world!
maybe a series of belts and pulleys
this is amazing ! <br>you should design an air powered car ! that thing would run itself. you would become a millionare
especially if it ran of flatulence!
not if theres a reservoir :)<br>
vedry good
Nice Ible, a teacher needs to run it through a spell-checker though....
Not the first time thats been said....a combo of dyslexia and monkey typing results in some dodgy spelingz
Where are you based ? If you're doing this in the UK, it makes great ammunition for me and the head of DT at the school I help in to go for funds. The &quot;school lathe&quot; is a disaster area - there's no lubricant been near it for 20 years. <br><br>Steve
Im based in south cambs / north essex is that anywhere near you? if it is im sure we could arrange a visit to our school to see the awesome stuff we do in graphics, resistive, engineering, textiles, electronics and food.
I'd like to really kick things up in my sons' school. DT is a dead end topic there. It sounds like you're running it the way I would ;-)<br><br>I'm up in Lancashire. <br><br>Steve<br>
Hey Jonny,<br><br>I would say that this could run as a steam engine as well, just connect it to a steam boiler instead of a compressor.
it absolutely will :) however home made pressurised steam is not allowed in a school unless the boiler pressure tested by a H&amp;S company :( its a shame H&amp;S is killing any fun we might like to have in life!
In the UK at least, model engineering clubs often have people who can pressure test small boilers with the correct hydraulic equipment.
your probably right, i would expect its excluded from all schools. I have never checked as I would not allow my students to make one......just in case they got hurt....... its a shame really :(
Also, most schools budget their funds in favor of sports programs, mainly football.apparently little Johny throwing a football 150+ yards is more important than Billy being able to design a high-efficiency steam engine.
That's sooo sarcastically true! I wish it were the other way around!
Nice! Just don't forget to post it!
This excellent on many levels. First, it's a great instructable. Second, it's great that you're doing this level of work with kids of that age (or any age in school.) Third, it's a great device by itself. You should be commended. 5 stars. <br><br>Vince
Hi, thanks for the nice comment and the awesome patch :) i like your kinetic man it made me remember back to when I was 13, as i made one at school! but it was nowhere as cool as yours.... I will investigate the idea further.... watch this space :)
these are better done than the work of some 18 year old students at my school
Well he does have access to materials, mills, lathes, and casting equipment. Your average middle/high school usually doesn't have any of that.
Its not that a high school is missing equipment...... they are missing the right tech / shop teachers who pester local companies to buy the equip for the school..... just like we do at our school
More like H+S policy excludes it - it does in the school I volunteer in.
