Hi Guys, I am not a big fan of politics or politicians or the awful anti indigenous/racial equality laws they have passed. I fully support this seller`s right to sell, or not sell, his possessions to who ever he chooses. I do not believe in racism in any form at all, and try my best to judge others, equally, based on their character and proclivities. I can think of nothing worse than a society in which I could be compelled to sell something that I own to someone I do not like. If I don`t like someone, that is now going to be classed as racism/sexism/?????phobia? How dare they! If you don`t like my old fashioned rules at least have the guts to come and see me to discus it, don`t just pass anti hate laws that make me a criminal!

I think and hope  that most of the people on this forum still live in countries with democratically elected governments and I have always respected that concept. There are some people who do not accept that principle and will try to thwart the will of the majority of people by challenging freedom of expression and thought and deny me my right to chose who I like and who I don`t.

One of the primary reasons for my leaving the UK and emigrating to Australia was that I no longer recognized the country I grew up in. Parts of London and the UK have become  ghettos filled with various ethnic minority groups with far more rights than the traditional indigenous population.  There is  an ongoing sh1t storm about what to do with the returning UK citizens who went to fight with Isis in Syria. These people voluntarily went to a foreign country to kill infidels. To them I am an infidel! Yet they believe they have the right to return to and live in the UK, where the indigenous population are expected to welcome them with open arms and give them housing and welfare benefits! These idiots then have the gall to complain if I don`t like them and choose not to sell any of my belongings to them!

I hope and believe that we are seeing the end of liberalism. The election of Donald Trump was probably the first evidence of ordinary people saying we have had enough of this BS. The vote for Brexit in the UK has shaken Europe to it`s foundations and it looks like the idea of a federal Europe run by socialists is about to collapse.

Martin luther King had a dream in which all people were treated equally, regardless of colour. He went on to say that they should be judged by the quality of their character and the sum of their achievements. As far as I know he was never exposed to the sort of 1984 Orwelian nightmare we now have to put up with. I wonder what he would have to say today?

Leave the guy alone and let him get on with it.

Well done Alex! I am so glad to hear the old family heirloom is back in action. You should certainly repair any wiring that has been damaged by mice or age. I would recommend that you try to find as close a match to the original wires as possible, When I did mine I found that some auto parts places had a very good range of different coloured wires in different gauges.

Looking forward to seeing the results.

Hi Glort. when I bought my Lister CS, the farmer also had a YBT. I chose the Lister because it turned over, while the other was seized. Parts for Lister engines are readily available,.New parts for old Southern Cross engines would have to be manufactured at huge cost. That said, you only have to look at the work being done by 38ac to see what can be achieved by a determined and skilled individual.

When it gets dark here I can see the entire Milky Way in the sky, No wonder that earlier people worshiped the heavens and learned to use them to navigate the globe.

Gen heads in Australia at a sensible price are about as common as rocking horse sh1t. A sensible fellow with a few bucks could make a small fortune importing them and supplying parts and expertise. If I was a young man I would be doing exactly that.  I would set up a web site offering generator heads and adapter plates. pulley wheels, vee belts and etc. I doubt you would get rich but I think you could make a very good living.

Hi Guys, I`m very glad I did this setup before my car accident and subsequent heart attack. I couldn`t begin to tackle a restoration like this now. My recommendation to anyone thinking of doing anything like this is: "do it now, tomorrow may be too late!"

Hi Glort, always difficult to find a compromise between maintaining a happy wife and satisfying your own proclivities, good luck with the drive.

Thanks Mike, I`ve been looking at a few Youtube videos and it would appear that the injector pump timing must be adjusted with shims as there is no access to the plunger or cam that drives it. Interestingly the fuel injector is side mounted in the head.

I`ll flick an email to Rob once I get the engine here.

Hi Mike, since these are air cooled sound proofing is an issue. My generator shed is far enough away from the house for this not to be a big problem, it has a concrete exhaust chamber buried in the ground which helps. I also made louvered doors for it, which also reduces the noise. I have never experienced any vibration problems but that might be because it has rubber mounts and is bolted down onto the 150 Ltr fuel tank. The picture will explain everything.

Other Slow Speed Diesels / Southern Cross ETB diesel engine
« on: February 13, 2019, 12:28:10 AM »
Hi Guys, I am awaiting the delivery of a Southern Cross ETB 2.5 HP diesel engine. Manufactured in Australia circa 1950, they were also manufactured briefly in South Africa. This engine has sat in a mate`s shed for the last 20 years. I have finally persuaded him to part with it for free!  :) 

Sadly it is incomplete, missing the fuel injector, pump and fuel lines. The originals would have been made by an Australian company called Pyrox, who manufactured injectors and pumps under license from Bosch.

I have been unable to find much out about the missing items but believe they are very similar to the units used on a Lister CS 3/1. I suspect that I might have to change the injector nozzles and fiddle with the pop pressures a bit to get them to work properly. Any thoughts please?

I have attached a photo of a complete ETB I found on the internet, probably a breach of someone`s copyright, for which I apologize in advance. I will post photos of my unit once it arrives.

Love you too!  :laugh: I`m not in the market for a second ST2 but it will be interesting to see what it goes for.  I spent around $1000 on completely rebuilding mine, re-bored cylinders, new pistons, bearings, bushes and etc. Total cost for the project including the generator shed and wiring about $3000.

In my opinion this would be a very sound investment for anyone with the time and skills. It would happily drive a 7.5 KVA generator or a large water pump. A lot more economical and long lasting that a petrol generator, for not much more money.

Lets hope someone gives it a good home.

Hi Alex, I`m pretty sure everything on the output side of things is OK. Start it up and see what happens, the main field winding should be energized during the starting process. My only concern is the lack of continuity across that main field winding. The problem might be the connections on the wire wound rheostat.

Generators / Re: Brush Wiring Diagram E9840322
« on: February 11, 2019, 09:36:06 PM »
Hi Simon, thank you for your drawing, very informative and well done. Generally speaking the wires should be labeled with coloured shrink wrap. The AC wires (one to the slip rings and the ones to neutral in the top box) are usually black, The +ve wire to the field is red and the -ve wire is white. Sadly many years of dirt heat and deterioration often make them indistinguishable. However, a close look at your photos shows two of the wires attached to the rectifiers appear to be brown, I suspect these are the +ve field wires.

I am hoping that one or other of the old rectifiers still works, if you disconnect the brown shrink wrapped wires you should then be able to test the two rectifiers with a multi meter. If you set the meter to Ohms, put the red probe on either of the AC terminals (connected to chassis or slip ring) then place the black probe on the vacated rectifier outlet you should get a reading. Now reverse the polarity of the probes, you should get no reading. If this is the case then the two wires with brown shrink wrap are indeed the positives for the auxiliary field windings.

Let me know what you find, please be careful with old selenium rectifiers their contents are toxic.

Hi Alex, I think we are getting close to diagnosing the problem, You should have continuity between 13 and 16/17. Without it you will not energize the main field. Please confirm continuity between 13 and 19; please also confirm continuity between 22 and 16/17.

Hi Jonny, when you say that your line contactor does nothing are you saying that it does not move? If that is the case then some silly bugger may have disconnected it and replaced it with the RS relay shown in your photo. Could you please post a photo showing what you have left in your wall mounted control box.

The decompressor solenoid is driven directly from the generator top box, as the brush head starts to generate it activates the solenoid engaging compression. When you shut down the generator this releases the solenoid and a spring pulls the decompression levers back into the ready to start position.

Nice work Butch, I spent years working a lathe and know how time consuming this sort of work is, especially if you are having to make your own tooling.

Do you have the original fuel line or are you going to have to make that as well? Will it have swagged/flared ends or  soldered/brazed brass ferrules?
