Aussie Aqueduct Poo Pipe
A very unusual bridge in Geelong, Australia. Heritage listed, which is the only reason it has not been completely demolished by the owner.
Despite its unglamorous function (transporting sewerage), it has some charm, IMO.
And let us not forget that sewers and reticulated water supply have saved more lives than every doctor, operation and medicine. Ever.
I do not beg for likes, but a comment is always appreciated.

Stripping 700 meters of house supply wire, using a $AUD60 Ebay supplied machine, driven with a battery drill. The wire was pulled with a tractor from the buried pipe , damaging the insulation in places. I estimate that there is about 250kg of electrical grade copper. The stripping machine worked effectively and very quickly, except where the insulation was damaged. Loose bits of insulation bloc...

Demonstration of firing an Armstrong 110pr breech loading cannon at Fort Nelson UK. Note the securing of the breech block by 2 gunners swinging the weighted handle thrice. And the huge cloud of smoke which results from only 2lb of gunpowder. Just imagine the effect of 20 lbs which would have been used originally.

Motorising a Mill-drill table
Просмотров 2273 года назад
It was becoming too difficult to raise the table by hand on my mill-drill so I motorised it using a hand drill, a pinion and a gear. This video summarises the process. No plans because everyone's setup is different, but you will get the idea.

Hi John i have just finished a marine twin and I'm going to make a Stuart triple next. I am going to (try to) make the crank from solid and machine the intermediate eccentrics within the crank (is this a bad idea)?
Hi. I have made 4 solid crankshafts, of which 2 were useable. And they did not include solid eccentrics. Bear in mind that without including the solid eccentrics you will need 4 centres to machine the mains and big ends. If you machine the eccentrics with the crankshaft you will need 10 TEN! centres at each end (assuming a reversing engine), which I would think would be incredibly difficult in such a small model. So yes, I think that split eccentrics is more sensible. But absolutely make a solid crankshaft rather than a built up type. John.
@@johnv341 Thanks for the reply John..I will probably just try the IP pair
@@modelengineeringadventures I will be very interested in the outcome.
Hi John: I don't know how to message you privately, so here goes... You gave me some advice a few years ago about this particular engine and I went ahead and built one from scrap metal. Thank you for your help, and I'm sorry that when I made the video I accidentally said you were Keith Appleton, and I don't know how to edit my video to correct that. ;-( Anyway, thanks for your advice and here is the link to my freshly built engine. ruclips.net/video/vpRbUeN01KU/видео.html Cheers, Bruce.
You are welcome Bruce. I am happy to have helped a little.
Very Impressive mate! I'd kill to have an engine like that
Very impressive little pump. I love the sound of it pumping & it’s a fascinating pump to watch! Very well done! 10/10 ✅👍😊
Great video John, interested in seeing more of your bridges in the future.
Amazing John Always great to see your Videos and Models too.
Hi John. Thank for the prompt reply. I’m sure I can work things through but I’m a great believer in not trying to ‘re-invent the wheel’! Best regards & happy New Year. 👍
Have you changed the resolver/encoder on the headstock spindle to get a better resolution for threading?
sorry, I don't remember what setup I was using back then. So many changes and upgrades to that lathe over the years. All of the motors including the main spindle motor and steppers , and the electronics have been ugraded.
Hi John. I would very interested in how you went about converting your drawing/idea for the component to the g-code for the Boxford 125 TCL. Is that a spherical or epical body for the steam valve? I intialy got the 125 TCL lathe to make a few steam fittings for my 7.1/4” gauge loco and other steam related projects. I’m in the process of converting to Mach 3 not having the Boxford suite of software.
The Boxford software which came with the 125TCL is ancient so I would encourage you to convert to Mach 3. I generate my G codes on V Carve Pro, which is really designed for CNC woodworking, but with appropriate feeds and speeds works very well with metals. The valve body is spherical BtW. Another G Code generator which I often use is "Ezilathe", which was written by Stuart Tankard, and is available for no charge. But you do need Mach 3 first.
That's some beefy wire! What gage is it? Melting and casting that copper into ingots is the fun bit!
Hi Richard, each cable was about as thick as my little finger. 3 cables to supply the house site. Quite heavy, 3 pieces 1m each weigh about 2kg. Yes, the ingots should be fun, and who knows, might even end up in future models.
I’m subbed
Vary nice!!!
How can get blue print of it?
I suggest that you do a Google search on "Jerry Howell". Plans are available at reasonable cost
Might make an interesting milk steamer, too!😄
What a beautiful little well-built machine!
Do you have a link to your build for the 3rd axis please
Sorry. Never detailed the build in a blog. And now forgotten the details. You could query stuart engine builder.
I’m not a speed reader wtf
and I am not very good at making videos. I guess that not many of us are perfect.
you could do without the music!!!
My video, and I like it. Turn the sound off if it bothers you.

That is pretty impressive!
do you think you could coal fire a single flue boiler like this at such a scale?
With only a single fire tube-flue this is a relatively inefficient boiler, particularly at this scale. I tried several solid fuels including coal but could not get enough heat to make the engine function. It works well on propane from a Sievert burner as you have probably seen.
I made several model cannons which used this pattern of traversing platform. The carriages varied a bit with the size and style of the barrel, but the traversing platforms were always identical. This rotting, unrestored platform was incredibly useful in revealing the usually hidden secrets of the construction, mainly due to the windows provided by the rot. I referred to this video many times during the construction of the models.
According to boe jiden you aren't allowed to have a cannon. Lol
It is a model, and cannot be fired. LOL🙂
G’day John did you get castings from Boltons? Very nice model and boiler. Regards John
Hi John, castings were purchased from EJ Winter, Sydney. Ben deGabriel is very helpful.
G’day John that is very impressive how you did that conversion to CNC, it looks good to it must of been expensive to do it. I suppose that the positives outweigh the cost anyway goos video kind regards John
Thanks John. Back then it cost about $AUD2k for the conversion, would be less now. I had expert help with the wiring and Mach3 setup. And yes, it has enabled me to tackle some complex turning jobs which would have been very difficult or impossible otherwise. That cost does not include the lathe, computer or software. I sometimes wish that I had put my conversion efforts onto a bigger, better quality lathe.
G’day John good to hear from you yes your right about the cost, it would be terrific to have. Do know anyone other than Winters Bolton that you can get castings and drawings, just somebody else I’m not happy with their castings they are very hard and Chilled and these are big parts. What do you do on yours thanks mate kind regards John
@@johnkinnane547 I have been happy with my castings from EJ Winter, but I believe that they might have had some changes in suppliers in recent years. You could use bar stock, or fabricate parts, or get cast parts from UK suppliers, but UK postage is quite expensive. I have used bar stock for my last few models because commercially cast parts were not available. Also, you have probably seen that I have been making my own castings, but that is a whole other technology to get to grips with. I must say that I have always found Ben deGabriel good to deal with.
G’day John I am building this engine at the moment, I hope that you don’t mind if I ask a few questions. Did you have any problems with the cylinder fitting in the four jaw chuck I can only get the jaws on the rim of the cylinder it doesn’t look enough in the jaws, Did you have any problems with the flywheel being chilled and very hard to machine. I hope to hear from you thank you kind regards John Kinnane
Hi John, I made that engine over 10 years ago, and unfortunately I don't remember how I managed to machine the bore. I dont have any photos to help. It is likely that I used a boring head in the milling machine, which is how I did it in later engines. The flywheel casting does have a hard skin, and carbide insert tooling is best.
HOW CAN IT BE TURNED INTO V FORMATION
I would not contemplate doing such a thing to this iconic engine.
@@johnv341 no like duplicate the triple expansion system to an v8 engine
Awesome. These small model engines built with higher strength materials and run at high steam pressure (800psl) can actually be used to drive small cars and motorcycles
What a fantastic job it ticks away like a Swiss watch. Regards John
G'day John I have the same problem suffer with rheumatoid, osteoporosis and fibromyalgia and I 64 yo I have a HM 46 and it's very hard for me so thank you for the video. Kind regards John
G'day John and Greetings from Tasmania, I am building a No 7 Boltons mill engine and yours is terrific so I'm hoping you wouldn't mine answering a couple of questions about the build. Firstly did you find that the castings especially the valve chest being right on the measurements only allows for very fine milling, the other thing is did you find the flywheel casting chilled and very hard to machine, I would really appreciate any info on this. Kind regards John Kinnane
Hi John, sorry for the late reply. I don't often check my YT posts. The Bolton 7 was the first model which I built from castings and that was a decade ago. So I have forgotten most of it. I do remember having to break through the outer layer of the flywheel with a good insert cutter. And there was very little machining allowance on some of the castings. I seem to remember using JB Weld to pack out some hidden bits. There is usually a workaround, and that is half of the fun. Or is it frustration? These days I tend to use bar stock. You get a second chance if you stuff up the first effort! Good luck! ps. you can buy cast iron bar stock if desired but often brass, bronze or steel is suitable. John V
that looks hot!
Yep. I have lost count of the number of times I have discovered that painful fact.
Did you add another encoder to the spindle in order to be able to thread on your machine?
There is a single slot disk on the spindle with a detector to accurately measure RPM and starting rotational position. The actual RPM rarely exactly corresponds to what is programmed into MAch3, and there is always an acceleration and deceleration period, so the encoder on the spindle is essential. Every CNC lathe has one or should have.
@@johnv341 do you use a smoothstepper or just a bob on its own? I’ve got the disk with a slot in. The slot in my disk is around 7mm wide is that wide enough or would you say it needs to be wider? Thanks
@@minimillaidan369 7mm should be plenty. smoothstepper now, but cant remember setup when that video was made.
@@johnv341 great! Out of interest what some stepper and bob are you using! Thanks for response 👍🏻
the sound of the engine is superb
Too Good.
Thankyou!
Hello I inherited a part build engine that looks like yours. I’d like to send you pictures of mine. Maybe you can help with some more information? Thank you in advance, Michael
Hi Michael. Happy to help if I can.
Beautiful engine. One thing I have not been able to work out on Trevithicks engines is the cylinder lubrication. With the steam coming directly from the boiler how can you lubricate the cylinder.
Thank you! My understanding is that there was no provision for lubrication of the cylinders of steam engines of this era, and my model, except for that provided by steam and water, which is better than nothing.
@@johnv341 Thanks! I have recently become fascinated with Trevithicks engines after his article in the April Heritage Railway and am looking for more info on them.
I think i'll built one of these. What a great looking engine
Thankyou! Completely hooked me.
@@johnv341 I've started building it. Few months time and i'll be done. Also have an 8 inch copper pipe that i'll use for a coal fired boiler
@@johnv341 My engine is now built and I'm just finishing the pump. Next to built an 8" coal fired boiler.
Latest environmentally friendly technology 👍
When did your opinion become relevant?
@@gholloway9935 the day I gave it to your mum up her backside 👍
If you really want to see how well this is going, put a vacuum gauge on the exhaust pipe between the LP chest and condenser. If you are pulling a vacuum the condenser is truly doing its job. You should find that the small pumps next to the Edward's pump are the boiler feedwater and makeup pumps driven by the engine, use a recirculating valve the control whether they feed or not. You want a far greater cooling water volume through your condenser than what those can provide.
Brilliant gauge, I see it says Smiths on the face, are they still in business?
Don't know, the gauge was donated by a friend.
Fancy seeing AE here! Smith's are still in business, they mostly make gauges for racing cars these days.
My friend David Arnfield saved this engine.
Well, congratulations and thanks to David. It is a fascinating engine.
@@johnv341 nothing like a non-dead-centering!
I love your videos and I love your work. Do you take commissioned model engineering jobs?
Afraid not. Too many hours to build them. But thanks.

Hi John, I have been through your blogs. I really enjoyed them very much. Great work sir!
Glad you like them!

Beautiful engine. Would you sell it?
Thankyou. I would estimate around 2000 hours work. Now what would that be worth I wonder?
@@johnv341 I understand the approach. I have been looking for a triple for a long time and have now chosen this unusual way via RUclips. Maybe you can name a reasonable price for your work.

Love every detail, a real 'eye catcher', square headed nuts and bolts (didn't buy those!) and the safety valve, neat. Thanks for sharing.
I confess that I did buy the square nuts. From China. and thanks for the nice feedback.
Excellent video. Thanks. It will be a great help to me, my kit arrived a little while ago and about to get started on it, so I now know what to aim for. You now have 1 more subscriber. Keep on putting up the videos. You are good at this. Happy New Year.
