About Me...
I started model engineering and building model stationary steam engines in 2015, after constructing a small engineering workshop in my back yard, I use a Myford ML7 hobby lathe, a Dore Westbury milling machine, along with a pillar drill, band-saw and the usual hand-tools associated with hobby engineering and enjoy making model engines and general tool-making and metalworking. Nearly all of my engines are scratch-built without drawings, from available bar-stock, starting from an initial idea and allowing the design to evolve throughout the build process. I do occasionally use drawings from the web, as a basis for a design, and then modify it to suit my needs, using mostly metric dimensions, but often mix metric and imperial. I spend countless hours in my workshop working on a single engine, and much frustration can be involved, but all this is eventually offset by the pleasure and excitement of seeing my model engines take shape and eventually come to life. My shed is also my sanctuary, somewhere I can go and forget about the worries of everyday life, to occupy my mind and hands with something creative and fulfilling, where I am free from distraction and interruption.

Thanks
Thx for the vid.
Lessons learned. What a fabulous result. Thank you for sharing. 👏👏👍😀
Great video, like the free plans. Your website isn’t very friendly with hand held devices 90 % of the information is cut off when using my iPhone got the same in horizontal as well as vertical. Your channel deserves a like and subscribe
Thanks for the info re my website, it is supposed to convert for mobile devices so will look into that. Thanks for the sub !
@taranson3057 - Hopefully the mobile site is now fixed :)
Great job Ade, looks fantastic.
Thanks 👍
Thanks for sharing 👍
Cheers Craig :)
Spectacular project mate:))
Cheers Yaniv :)
It’s really nice. You made a lovely job of blending the radius on the cylinders.
I am a raw beginner in model making and your videos have been my classroom for learning metalworking. Keep up the great work.
Thanls William :) Enjoy your model engineering journey
Hello Ade,
Very good video, it was interesting to hear how you designed the duplex twin... I like the conical springs, they are a nice finishing touch to your engines.
Take care.
Paul,,
So smooth and love the sound it makes. 👍
This video gave me some great tips to use in the future. Thanks for the great troubleshooting pointers for those little engines. Thanks for the information about deciphering the numbers for the springs.
Wishing you and your loved ones safety and health during the upcoming holiday season and beyond.
thanks Ade for deciphering the spring codes

Lovely engine, hope you survived last nights stormy weather. So that's what he was building in there he he
Cheers Nige, the shed roof is still intact :)
Awesome job, beautiful engine!
Super
Another beautiful example of craftsmanship. Thank you very much for sharing with us all. :)
You are welcome DannyC, I'm glad you enjoy my little engines :)
Another great engine. Thanks for showing it to us!
Thanks MH :)
Nice job!
nice film and great to see the 'duplex' engine come to life.
the cranks are 180 degrees apart? and the engines about 20 degrees. i will try and build one and see how it goes. thanks Ade... our wood pellet central heating boiler is in my workshop so always a toasty sanctuary.
Thanks Simon, yes 180 degrees, and 20 for the chassis, I might start the drawings this afternoon as the weather is frightful
@@AdeSwash thanks Ade, i made a hay feeder for the sheep......freezing rain made it a little chilly outside.....brrrrrrr.
@@ProfSimonHolland Its good to know it's not just the UK in the freezing grips of winter ;) Take care and keep warm!
Another great job !
Very nice Ade. Another lovely little engine 👍👍👍 Cheers, Alan.
Thanks Alan
Intering build nice one
Thanks :)
Good work, I love the simplicity of your engines. I think that these are an ideal intro into model engineering. The fit and finish of your creations is excellent. There are far too many channels demonstrating poor technique, which encourages sloppy work. Be interesting what you decide to do next. I am at that stage of “in between projects” I have been enjoying some quick and simple engineering or perhaps displacement activity before tackling something challenging. By the way, I still put holes in the wrong place and scrap parts, despite measuring twice or three times.
Cheers Simon, mistakes are just prototype deviations ;)
Now you have your cnc you can use it - maybe not for cutting thick metal, but certainly for marking outlines and hole centres with a v-bit.
Lovely engine, have you ever considered making your own springs with piano wire around a lathe mounted mandrel, pretty interesting.
Thanks Rich 10000, I haven't tried that as yet, but seen a few guys/gals doing it, so yep, one day I might do this. Thanks :) Ade
interesting ....
i would have been afraid that the three millimeters difference in height would block the steam inlet and outlet. Because the distance describes a radius on the outside diameter of which the steamports of the components lie, and the change in the radius affects the angle of the cylinder for the valve function. But certainly forgivable on this scale ..... grwat work and very informative! stay healthy Ade !!!
Yes, I did think about that being a problem also, so I added a small countersink to the cylinder inlet to upen the diameter of the mouth, not sure if it was needed but just thought it may help with the problem
@@AdeSwash thats what i would made to!
I love your videos and your engines are the pops !
Have you ever considered a
radial wig-wag ?
The design wouldn’t be that much of a departure just a whole lot more parts.
Hi Joedy860, I have often thought about a radial, but just haven't yet come up with or seen a design idea that I am happy with. I will let this one simmer on the back-burner of my brain until the time is right. Best Regards. Ade
`Thank you I enjoyed your site and engine plans I down lowed one then realized they are mm I'm in the US so not done much with mm do you have them converted I know a silly question but I so impressed with your work I have to ask
thanks keep up the excellent work
Hi Allen, I dont have inch plans, but there are only a few dimensions which are critical and this is the distance between the axle and the pivot rod, and the port holes. These convert to 2 21/32 and 15/32 or 2.660” and 0.470”. The distance between the port centres convert to 15/64. As for the cylinder bore 19/32 is 15mm.
The rest of the sizes are arbitrary, so the axle could be ¼” and the bearings ½”, outside cylinder 1”x ¾”. The rest of the components and chassis make to approximate conversions, it should still run fine
@@AdeSwash I noticed that you used to different sizes10 mm and 8mm for the crank connector is there a reason
@@allendustin2837 the later engines use 8mm. It was simply an aesthetic change, as I felt the 10mm was a bit chunky
It's been a while since I 😌 and wanted to say Hi 👋. From Keith of Michigan. On Thursday we had a holiday, and on the same day, we had snow ❄ in my area, for the first time 🙃. I didn't know If I told you that I have my new Lathe, and placed it in my basement 😀. I just started to buy some material. Then I'll contact you about drawings, to build your running engine's. Take care now, it's almost December...
Cheers Keith, good to hear from you! - it is blowing a gale and snowing this morning in the UK, not shed friendly weather. Take care. Ade
Superb! I really am going to have to have a go at building one of these soon.
Could the 3mm be due to you measuring the standard distance but not accounting for the angle offset? So it should have been a PCD measurement from the centre of the crankshaft rather than a straight parallel distance from the centreline. Something that's tripped me up recently on a measurement of 67mm from a centre, have me about 4mm of error.
Hi Pete, its a good theory, to be honest I am not sure how I made the error, just glad I managed to rectify it :)
Will you have plans available for this little engine ? I might make it when the weather and shed gets warmer.
Hi Ro, hopefully draw some up over winter
Hi again RO, I have drawn up some preliminary plans for this engine, they are available on the wigwag facebook group for now, but will release them when they are fully established. Best regards Ade
FREE PLANS NOW AVAILABLE - see video description for link :)
@@AdeSwash Thanks Ade, i'll make it when the christmas silliness is over ! Thanks again !
