Glad to say UPS delivered my B.E.S. plumbing order nice and early so I was able to get on with putting it all back together.

A bit of heat released the Loctite holding the 1" BSP elbow to the various other fittings and having replaced the elbow with a Tee, the ballcock with one without a burst bit, and installed the 1/4" BSP air ball cock and PCL fitting I was able to put it all back on the wall. I took great care to mark the blue MDPE pipes for insertion depth and seat them firmly as both have to go on as an assembly - if I've got it right it wont leak . . time only will tell !

Then I removed the old nylon reinforced umbilical pipes that take the feed from the borehole to the heat exchanger, and the return that goes eventually to the stream via our land drains. I had bought some much more substantial stainless steel wire reinforced rubber 'Neptune' hose quite a long time ago as the nylon was a temporary solution - it had worked OK but wouldn't take kindly to a splash of molten metal. So now was the time to uses it.

All went well and I'm now waiting a few hours for the Loctite 542 to cure before I pressurise and test it.

The split / self fixing 1/2" wall insulation for these pipes has also arrived but the trace heating cable hasn't so I can't wrap up the umbilicals just yet. It's going to be great fun installing the trace heating. I've ordered a single  14 metre length the mains 'start of which will begin at the wall panel, wrap in a spiral round the return pipe, enter the chassis of the chiller wrapping round its internal pipes and exit wrapping around the flow pipe ending back at the panel. Or that's the theory - I can imagine quite a tangle during the wrapping !

Hi all,
another short video on some very interesting repairs to some metal antiques, preceded by a view of our freshly decorated front room ceiling wrecked by a pesky leak!! These things are sent to try us! I have been looking through my past (go pro) videos, and I am going to shoot some footage with it and do sound overdub because the wide angle effect on the go pro gives a farmore immersive experience! Feeling much better now as spring approaches and raring to get back in the shop full time!

Yes it was a scam.

The real owner came forward after I posted this message on Practical Machinist.

I have reported it to eBay.

Well done Bill.

Hacked accounts are all too common. It definitely  looks iffy.

It might be a hacked account - happened to me once, the only reason I found out about it before the **** hit the fan, was because someone asked a question about the DVD box sets I was allegedly selling, before any of the listings (there were about a dozen) ended.

I'm not entirely sure why I didn't get any e-mails from eBay stating I'd started a listing.... this was some time ago though, so maybe they didn't send alerts then. Fortunately everything else about my account (payment cards!!!) were untouched. Again, not sure why (having gained access to the account) said scammers didn't go on a bit of a spending spree on my coin.  Either I got lucky, or maybe they knew that that sort of thing WOULD generate e-mails?

If it seems too good to be true it usually is !

The Water Cooler / Scam? - 'it smells like one to me'

I have a number of standard searches on ebay for things of interest. Occasionally some comes up that is 'too good to be true'  and starts my alarm bells ringing. Today a very nice lathe turned up.

At the moment I cannot prove it's a scam and I am reluctant to call this particular item out , in case it is legit. So, let's just look at the suspicious  bits. (in no particular order)

The pictures:

 In the past I have recognised the photos as being of a fiend's lathe and so reported the scam to ebay . In this case , even a reverse search has found no originals.  The suspicion is the condition of the lathe; These are 'pride and joy' shots , the thing is polished and posed , devoid of swarf , unused.

The description: "Not only but also..."

The description tells us about the make of lathe, how good the condition: 'made to last a lifetime' .  But wait there's more! not pictured are parts that are very desirable that are hard to find and/or command outrageous prices (one item 'included' is typically listed at a greater price that most lathes) and he'll even throw in the 3ph converter so you can run this at home.

And of course the kicker: He can arrange transport.

There is nothing about why this immaculate machine is being sold .

The seller: 100% feed back... from 53 purchases

I'm guessing this is not the lathe 'owners' actual account (wife/girl friend, ex-?)  , since the items bought (none sold) include fashion, shoes , garden and general domestic purchases. No machining parts tooling etc.

The location: Arseendofnowhere (or near to the 'rigs' - see later)

I'm not casting aspersions on the good people of said county (counties) merely pointing out that the scam machine is rarely easy to get-to and not readily available for collection ( hence the' kicker 'above)

The scam:

The object of the scam is to relieve you of your money and leave you waiting in vain for the delivery of a machine . The story goes something like :
it's for sale because ... bereavement, new job , emigration, exodus   etc.
the machine is not viewable ATM because  , i'm on the off-shore rigs for the next X weeks, or it's in storage, or it's packed etc. etc.
Yes , you can send your own courier. but...
If you send the money ... I'll pay for the shipping ... pay for express shipping ... throw in the girl fiend/wife /ex  etc. etc. etc.

Anything  - as long as you send the money.

The scammer:

Usually male , probably knows something about machines , probably hangs about in forums like this one (Hi, scammer). The may only be a few such people currently operating.


The morel:

Be careful , it is so easy to 'want' something so bad, that ones brain fails to operate normally (under no circumstances go shopping after drinking alcohol - beer goggles work on everything) .
The old old adage 'if it looks to good to be true - it probably isn't" should be first thing in your mind

In this case I cannot prove it is a scam so I cannot act, other than to warn others .

Today I stripped down the water feed  and return pipes from the Borehole to let me take the panel off the wall in the foundry and investigate what actually has burst.

To my surprise I've found that the actual body of the ball valve has split - it's a dead ball valve  :bugeye:

So having ordered up a replacement I've also decided on a 'frost strategy' for the future. The pipe rises from the ball valve and goes through 90 degrees to a convenient  place on the panel. I will replace the 90 degree 1" BSP elbow with a Tee - and the extra 'way' will be reduced to 1/4" BSP, have a 1/4" Ball Valve followed by a 'Male PCL' air fitting.

This scheme should allow me to 'blow down' water from the pipe work and the side of the heat exchanger that isn't antifreeze filled.

As an extra line of defence I've also ordered decent quality pipe lagging and am off now to hunt for a suitable length of frost stop heat trace cable.

Frost prevention measures:

My first thought had been the wrap snti-frost tape round the two umbilical hoses that join the water chiller to the flow and return mainifold to the bore hole.

Now tape isn't particulary convenient on flexible pipe but it can be done.

Then I thought: the return pipe is open at the well end - can I adjust the piping so that opening a ball valve it all flows out. But no, the height of the manifold compared to the heat exchanger prevents this.

My current thought is, if when I make good the frost damage on the flow pipe I incorporate  an air input valve, when cold temperatures threaten I can maybe blow the water from both the flow, return and heat exchanger back down the return pipe (thus overcoming gravity) leaving hopefully minimal water in the system.

Any other suggestions would be very welcome.
