5 grand for what is essentially a motorised treadle lathe. Astonishing.

I have just bought the same machine. Mine is convertible to horizontal milling. You can read about it on the mig welding forum. See my posts entitled eBay-tastic.
Thread: Fuelling a Boiler using Electricity
20/03/2018 12:04:38
The thing is. Generally the steam is used to drive a turbine to produce the electricity. Not the other way around. There's a good reason for that.

My earlier post refers.

I saw a video of one of those in a chemical works in the 70s, think it was Runcorn. The tank was filled with steam from an external source.

Alternatively one could use the electricity to drive an electric motor which would be coupled to the wheels through suitable gearing.

I don't mean to be sarcastic. Just playing devil's advocate!

I think in the current climate that I'd better not.

There was a story from the US many years ago about a young man who distilled some isotope or other from gallons of glow in the dark paint.

The story was called the Radioactive Boy Scout or similar. He understandably caught the attention of the authorities.

Reminds me of a conversation I had with my brother about power plants for model boats.

The conclusion we inevitably came to led to us researching (for purely academic purposes, you'll be glad to hear) just how small you could build a working nuclear reactor.
Thread: Can Someone move a mill for me please?

Thanks for all the info and reviews. I've got the seller palletising the mill for me, very kindly I might add.

Just waiting on a quote now.

You trying to be funny?!

Hello Chaps,

Thank you both for your help. I was really hoping that the LandyLift chap's email and details were going to crop up. I knew that he had delivered John "Doubleboost" Mill's Harrison 140 when he got it, but I couldn't remember the name or number.

I'll be getting in touch with him. I'm going to be putting a VFD on this mill for the main motor and the 1/8th horse power feed. Also generally giving it a good go over, so it should be interesting. I've been putting a VFD on my Harrison lathe and a DRO too. I've been posting over on the Mig Welding website about that stuff.

Thanks again, I will let you know how it all goes.

I've just bought a Harrison Vertical milling machine. The slight snag is that it is located in Derby, whilst I am in Morayshire. The machine is about 750kg I believe.

I was wondering if anyone might like to quote me a price for uplifting the machine and delivering it to my address. My post code is IV36.

You can either reply to me here or PM as you wish.

Many thanks,


Thread: Steam generator
27/01/2018 14:35:48
Yes Brian it did.
27/01/2018 14:34:55
Yes vintage engineer they could have used silver. After the war Britain dud just that, not only to produce steam but for the rocket engine itself. The peroxide went through a silver catalyst into the combustion chamber. The oxygen gas and steam was then so hot it would ignite the kerosene that was then injected in.
27/01/2018 09:09:45
Why did they need to generate steam?

To drive the turbo pump that pushed the fuel and oxidiser into the combustion chamber.

The V2 also did the same, as did many other German rockets. The fact that it was a steam generator is incidental; it should really be viewed as a gas generator.
27/01/2018 00:36:35
Just as an aside that steam generator is an almost verbatim American copy of the Walter one in the Me 163 Komet rocket aircraft.

Just to let you know that I can 3d print, highly accurately and in high impact materials any change gear you may require. Pm me for details.

Yes I've looked at Nitrous Oxide as an oxidiser. I've also looked at the possibility of decomposing it over a catalyst to obtain hot oxygen gas.

Unfortunately, even with the most active catalysts a lot of energy has to be put in to start the reaction. And the most effective catalyst zeolites are also prohibitively expensive.

Nitrous Oxide would still be my oxidiser of choice, combusted in a conventional way.
26/01/2018 19:14:12
I know what you mean. However, 90% or high test peroxide ain't no household chemical. It will kill you soon as look at you.
26/01/2018 15:06:58
Getting the home office licence to purchase and store is not that big a deal, but the storing of it in anything except a purpose built facility would be problematic in the extreme.

It's classed as a hazardous chemical, a fire risk and an explosive ingredient as well as an oxidiser. You'd need proper facilities to contain any spills and to deal with them. So for anything less than a fully funded company with proper well founded premises it's a non starter.
