New model GPA? Something went wrong...

It doesn't seem to say where it's going to be, but using a bit of detective work on the plan that's on the website (mentioning some place names) it looks like it here - https://maps.google.co.uk/maps?q=canwick+hill+near+Lincolnshire&hl=en&ll=53.213974,-0.527413&spn=0.001821,0.005284&sll=53.177355,-0.626536&sspn=0.115846,0.338173&t=h&hnear=Canwick+Hill,+Lincoln,+United+Kingdom&z=18 Website is here - http://www.lincsbombercommandmemorial.com/our-memorial.html

Brooky (Chris) mentioned a firm to me recently re: making a scammell gasket. I haven't tried them yet but you could give them a whirl. http://www.classiccarwebsite.com/johnson-gaskets

Maybe they're all 12V (with any luck). In that case there's nothing to worry about, commercial ones should be fine

lol yes, but we don't know if its 6 volt or 12

is it the ship that deployed the route marker buoys for d-day?

once we know what truck he has we can give him the right advice for his truck

No, compared with electric batteries or local recharge of an accumulator.

Personally I found that they top out at 50mm2. For 6volt you really need 70mm2 or more. I made my own with a decent rated 70mm2 (650 Amp) cable and double-crimped connectors.

Is it 6V or 12V? A lot of the battery cable commercially available these days is meant for 12V and can't handle the current load that a 6V starter would put on it. That rules out a lot of the pre-made options.

It's more of a problem (to my thinking) of logistics. I can't imagine it was very easy to transport and store calcium carbide in quantity in the sort of conditions that were experienced in ww1. I'd imagine damage in-use was a concern as well though.

I'd imagine it had some good advantages against carbide lamps if you could keep the batteries going. Not releasing explosive gas when wet for a start. Would it be using rechargeable (lead acid?) batteries or dry cells that would need a supply chain?

I'm surprised things have degenerated to the point where they're erecting a fence through the Bletchley Park site, cutting it in half. Last time I visited I found both museums to be part of the story of the whole site. It seems rather silly to be cutting it in half, if silly's the right word when they're doing it on a site of international heritage in the name of remembrance. There's some info here - http://www.tnmoc.org/news/news-releases/deciphering-discontent-statement-tnmoc-trustees http://www.tnmoc.org/news/news-releases/bigger-picture-fragmenting-heritage-site and the other side http://www.bletchleypark.org.uk/news/v.rhtm/Statement_of_Facts-757580.html Let's hope they make some sort of agreement before it gets too far.

Nice one. What work does she need?

As there's no turret I wonder if this is either a Caernarvon, or one of the engine test Conq's ?

TC12 is a LSZH (low smoke zero halogen) cable. LSZH tends to mean that it's much better in a fire (less toxic gas), but can come at the price of less resistance to water*. As the AVRE is outside and not exactly water-proof (leaks like a sieve), it's something to keep in mind. Niether of the cables mentions water on the datasheet, but I'd play it safe and drop the manufacturer an email to see how it reacts. TC12 - http://www.klaceycables.co.uk/default/public/media/filemanager/TC12-cwtv.pdf Unipren - http://objects.eanixter.com/PD313733.PDF Alternatively, X-Mod have surplus Unipren 24 in stock. It's slightly thicker (4.1mm versus 3.1mm according to the above) but it may be a better option. http://www.thexmod.com/item_detail.asp?id=997. Again, I have no idea on how it reacts with water, but at least it's the type they originally considered appropriate for that environment. * Info on LSZH and water ingress here - http://www.molexpn.co.uk/Media/docs/Water-Ingress-In-Structured-Cabling-Systems-49b725ae-faf6-4516-9ab2-18fadc29c236.pdf

is it to stop something rusting? like a blade edge?

Could it serve a medical purpose, using the hot rocks to cauterise wounds or sterilise equipment?

Do the hot rocks become a weapon of some kind?

Building on Chris's answer, is it a fire pit to heat up the stones, providing a source of heat through the night without firelight.

Is it anything to do with temperature? Possibly condensing water on colder rocks, running down into the channel?

Field Maypole. Created from local materials and stones. Used when a regular maypole would give your position away. Raised edge provides cover for the Morris Dancers during use.

That's what I was thinking, and I've just noticed that the direction of attack is over the raised edge, which would further hide the installation from advancing troops. Nasty stuff. I'd assumed the raised edge was what you were protecting (a barricade or trench).

we got there in the end Interesting stuff Clive. I wonder how effective it was, and whether the idea of digging it in was so that it couldn't easily be seen until the unfortunate souls were on top of it.

Is it a dug hole?
