Do you have any pictures of those TS3 engines.

Larry

P.S. I hope your daughter enjoys there river boat. That would be real relaxing on one of those and you can change your back yard at will. I am curious do you have problems with mosquitos.

Apart from normalizing stresses Do you know if minerals from the soil leach into the casting.

Parting of a component in a lathe is always difficult regardless of the machine. Anyone who has not jammed a parting off tool has not made much.

One of the big problems that amature machinests have been programed that tungsten tips are the answer. This may be true for the larger more rigid lathes but for the small hobby lathe parting off can be a problem. I have always had problems parting bits all through my trade years.

The best parting tool I have ever used the blade was mounted at 45 Deg to horizontal and it never jammed. I don't know if you can get them now so I made my own. The reasoning is that if the blade is over loaded it moves away from the job.

I will attach some pic's

Yes Garden Island was a real learning time for me. I started on one of the 30 foot plainer then on the 100 ft lathe for three months. The big lathe was the icing on the cake 28 ft Dia face plate 365 HP motor.

By the way some of the small Chinese diesels have small injectors as well as small pumps,Worth a look.

Don't you sleep john or are you a night shift person.Where are you now. The UK.

I am in Rockhampton in Queensland.

Bamford showing hinged crankcase

Now I have been told that when the castings are buried they absorbe minerals from the soil ?

I had a good laugh at Erics comment which brought back memories of when I was asigned to a heavy machine shop at Garden Island Navy workshops which was on the harbour for shore. In the light machine shop the shed was on piles over the water and the shed windows is where the lemons were dropped into the harbour. After some time they sent divers down and recovered tons of brass and bronze.

The bottom picture is when it was pulled out of the river. The top two pic's were taken after sand blast & paint

Larry

Well here goes with the pic's

I heard of those indian engines as well and I believe they are full of elephant toe nails. Now think about what Rolls Royce did in WW2. They beried there engine blocks in the ground for twelve months before machining them.

Does anyone know what effect this had to the castings. And is it true?

Now apparently I have a rare engine here in my pump shed its a lister twin cylinder diesel GP4 and it was rescued from the bottom of the Murry river where it layed in water for thirty years.

As soon as I can I will post some pictures of it for you to see.

Also there is a company here in Australia that sells & repairs pump engines and the owner loves those old engines and I think they are lister agents.

In a town called Wagga Wagga in NSW there is a foundry that still makes cast iron gates and the owner would be interested in doing those engines.

By the way, getting back to engines.

Those Listers are beautiful engines but the one that facinated me was the Bamford with the crank case hinge.

The man that thought of that inovation was a real thinker and if they were manufactured today they would sell heaps of them. Its interesting, I wonder if the Listers would sell today if they were mass produced.

You have me totally facinated in that beautiful living area. Just think if you don't like your neighbour you drop the ropes and move away. How cool is that. My place is nice 1Km x 1KM but I would love to live on one of those boats for a while. Whats it like living on a canal boat.

Larry

Eric

So you have had a canal boat. They are real works of art, what timber do they use for the hull and are they corked with rope & tar.

I've seen them on TV in Australia but have never seen one for real. Are they roved with copper nails. Your so lucky.

Larry

Eric

Never the less you have done a great job.

By the way are you aware of the Bamford engines which has four bolts in the sump which you remove to work on the crank shaft. At the back of the block is a hinge so you can lay the engine forward and you don't have to drain the sump. Briliant piece of engineering for the time they were built. Those old low reving engines were real workers and my Lister is still running.

When I get a chance I will post some pictures.

All the best

Larry

Ennech

You have done a top job on that engine. I am curious regarding the injector pump, What are you going to use.

I have the real engine here on my property as a standby generator and there are a lot of bits in that injector pump.

Larry

Ron

Have you thought about bead blasting the areas effected.

Hey lads

Lets not get into a frenzy over a 60 mm turbo fan jet until I put a fire in its belly. I am having trouble with the donut or combustion chamber. A friend of mine who is a turbo charger expert for truck engines is doing the shaft balancing. Fitted with ceramic bearings to withstand the heat and rpm's we have a good chance of actually getting it to run. The funny part about this little device is if I can successfully get it running it will be the smallest and first miniature axial flow jet ever made. At the moment it looks promising but I am not scared to give it a go.

Now back to steamers you will see in my album pictures of boiler plates for the L20 traction engine which I have completed. The reason I have made dies for these plates is to make them available to less skilled people to help them get in to the hobby and down the track hopefully be able to produce boilers complete or in kit form at a low price. I also have dies to manufacture 5" dia plates.

Now does anyone know anything history wise about that Theil filing machine because I have been told they are very rare. The auto feed really has me tossed. Auto feed what ? That picture of the counter weights should give some idea of the mistory and it seems to conect to nothing. The only thing I can think of it should have a cable conected to a pushing device on the table.

Larry

Anyway lads I have sent of heaps of messages and I hope they make it to you.

In my Album there is a picture of a very small shaper. This machine was given to me by my friend Howard who lives in Wagga Wagga NSW. Howard is a collector of automatic lathes.

Anyway Howard was the mans workshop assistant repairing the old belt drive dental drills. We are still not sure of the mans surname but he lived in Hornsby a suburb of Sydney NSW. After the mans death his wife sold his patents to a US company who immediately crated all the workshop tool and machinery and had them dropped in the ocean in very deep water never to be seen again.But prior to the inventor passing away he gave the shaper to Howard as a gift of friendship. Now Howard give it to me and I am trying to find out its history and who made it.

Anyway if you try to find out who made the first air turbine dental drill you will be told the US did but it is not the case. I will get Howard to come on so he can tell the story.

Regarding the electron Microscope I was approached by a physicist from NSW university to make some parts for an electron microscope that he designed the process. The actual physical unit was still a blur so he would ask me can I make an item which was possible, and I redesigned it to make it fit the vacuum chamber. On completion of the unit which took 2 years the microsscope worked well and that was the unit that found the dust mite in air particles.

I can give you the peoples names but I will hold that back.

Nice to meet you chaps.

I have finally got some pic's up for you all so I uploaded some pictures of my new press I rescued from the scrap metal merchants. Its a Walbank 60 ton and it is down at the moment but It will rise again to punch out boiler plates for model steam engines. My vision is to make dies to produce cheap boiler plates to supply them to people who want to engage in the hobby who do not have the knowledge or workshop to make them. Apparently people who start to make steam engines and steam traction engines only about 10% actually complete their model so I hope I can help these people get there. And I am not doing it for money!!!!!. I have just completed all the dies for the Foden steam truck boiler.

As a toolmaker I believe that we all have an obligation to pass on our knowledge & experiance to the younger generation as my mentors did to me and I worked with some of the best.

My appretise master did his trade in the luftwofer factory in Germany and was the man who developed the machine for aluminium propellors.

As a boy of 15 I spent a lot of time with a man by the name of Bob ford working on steam boilers. Bob was Frank Whitles assistant when they developed the jet engine in the UK in WW2. A truly great man and I still have some of his books. The rest of his library is in the power house museam in Sydney.

I worked in research with Sir Charles Kingsford Smith's aircraft mechanic Charly Bromfield who was a great man to talk about steel and how to use it. His knowledge was unbelievable.

In my early days of my trade I built the first prototype of the back scattered electron microscope for Infra tube products which discovered the dust mite and was the most powerful microscope of its time.

I remember all the people very well and if I can be of any assistance to any one just ask. I have had three heart attacks and I want to pass on my knowledge if I can.

The small shaper in my album is the machine that made the first turbine for dental drills and I will insure this machine goes to a museam. By the way that small turbine in my album is a axial flow jet turbine I am developing for my model DC10 which is somthing I was told could not be done. It is still a work in progress and run at 120,000 RPM.

Anyway lads if I can help anyone in any way please ask, money is not an issue.
