  1. Can definitely recommend the PSG website.

    Theres a few case histories by member Tim Denton documented on the site who has done work with his local council and the Basingstoke Canal Society to preserve/secure boxes in the North Hampshire/Surrey area.

    Some boxes are listed - I know a series of them near Stonehaven on one of the Scottish stop lines are listed but it isnt neccesarily the case and varies around the UK.

    If a structure is listed you need Historic England/Scotland/Wales permission - effectively a form of planning permission to do any work.

    There is a downloadable database available from the PSG  site that you can use with Google maps to locate a whole range of defence structures. This also provides links to any entries in your local authorities historic site record or the CANMORE database in Scotland.

    I know its an old thread, but after searching for an article on the LSB conversion for the 321 I was sent here, looking at a one or two names I recognise, Iain I was in contact with you a few months back regarding the article by Leighton........

    Small world considering I'm a member here. 

    So I'm looking at converting one of my 321's to LSB and also giving a bit of lube and grease etc to the selector etc , I'd like to follow Leighton's article by the letter regarding the LSB, except I'll use the time lapse fuse as the switch, I'd also like to find out the supplier and contact details of the parts he used ?

    To ensure things keep on running without a hitch the The Great Repeal act transfers all current EU regulation into UK law. It is afterwards that they will be reviewed and changed as required.

    The idea is that so much is relative to EU law in the day to day running of the country it is necessary to continue as is and go through the huge amount of regulation at our leasure.....

    It is going to take a wee while !

    "Take a wee while" is probably an understatement....

    This is a nanny state gone mad!!!

    I seem to recall that legally, a de-activated gun is no longer a firearm - just had a look at the CPS guidance notes on firearms offences https://www.cps.gov.uk/legal-guidance/firearms, which defines a firearm as follows "A firearm is "a lethal barrelled weapon of any description from which any shot, bullet or other missile can be discharged". By definition, it is not possible to actually fire anything from a de-activated gun, whatever the spec, so it is no longer a firearm and therefore this new legislation would appear not to apply. Confused? I certainly am!!

    Any legal minds out there who could give an opinion on this?

    The whole driver behind this is the concern is that a de-act can be reactivated..... this was also the driver behind the revised de-act standard brought in by the EU reg....

    Doesnt seem to take into account what has been physically been done to the weapon - again legislators passing judgement on things they have little or no understanding of....or the concept of the practicalities of what is going to be required in the aftermath....

  6. The very last sentence of the explanatory notes is quite telling.....

    Given that most constabulary's struggle to stay on top of the firearms licensing issue (if you hold a shotgun or FAC you'll be more than well aware of the issues) then what is going to be brought in between now and March 2021 is anyones guess...

    The area that Wally Dugan is referring to is the "Beaufort Dyke" which is a trench which runs along the bottom of the Irish Sea roughly around the entrance to Belfast Lough. The Dyke is 50km long and 3.5km wide. The gases which were recovered from the Germans were initially stored at Caernarfon before they it was discovered they were perishing and these were subsequently moved by sea for dumping into the Dyke. Surplus vehicles and all sorts have been dumped there since. Even today the area is quite dangerous with random explosions coming from the sea bottom as decaying munitions explode. Since 1995 incendiary devices have been found on the coast of west Scotland believed to have been disturbed by pipe-laying.  https://www2.gov.scot/uploads/documents/ae08beauforts.fh10.pdf

    There was a presentation at the Marine science conference held at the start of October  at the University of Strathclyde on the disposal sites utilised for ordnance post 1945. (The renewables industry are having to do a lot of clearance activities in the NSea for putting in the windfarm arrays).

    The subject of German nerve agents came up. The UK took the German Tabun stockpile (the US got the Sarin and this went back to the states) and it was disposed of having been stored in NWales - in Snowdonia in a former ROF store in one of the slate mines (clearance of the NWales storage sites is covered in the Arthur Hogben bomb disposal book)

    The Beauforts Dyke area was one of the key areas for disposal and there was an interconnector power cable laid in that area about 10 years or so ago.

    Supposedly the overboard dumping of material and the various ships loaded and then deliberately sunk were supposed to be beyond the 300 fathom contour - Beauforts Dyke was just the first bit of deep water outside of Cairnryan.

    There was no mention of vehicles being disposed of. Just large quantities of rotting ordnance.

    More recently when the MOD took the first generation of Accuracy international sniper rifles out of service these were cut up and dumped at sea.

  8. The L85A1 or SA80 was accepted into service in the mid '80's - seen dates between '84 and '87 so the 5.56mm rifle rack would be right for a 1986 LR

    Maybe someone on the forum can give a definitve date on the SA80 coming into use.....

    Guten Abend zusammen,

    The steering box is bolted in it's final resting position, which isn't exactly as per the original but because of the components that i am using it was always was going to be a compromise.

    DSC05774.thumb.JPG.0c44af45dfd9953fe6a5662d33d8aef2.JPG

    The final drives / reduction boxes stuck out too much from the side of the chassis, meaning that the front sprockets wouldn't be inline with the rest of the wheels. I therefore removed material from the castings, first of all with an angle grinder and then I finished them to size on the milling machine. 

    DSC05762.thumb.JPG.98a7d2af1da81e6d14eb86a3b139cf06.JPG  DSC05764.thumb.JPG.75b813e2d414834f93c08b4d1b8d8526.JPG

    The next problem was bolting the final drives to the chassis as I had cut the original studs off of the castings. There are six 1/2" UNC threaded holes already in the front of the castings that I can utilise but I need some in the flange area. The answer was to drill five new holes for M16 bolts and then weld bosses on the rear of the flange so that the flange bolt securely on to the chassis.

    The output shaft was then reassembled into the casting so that I can position the final drive housing onto the chassis and drill all the attaching holes.

    That's all for now folks,

    Jon,

    Nice to be away from the electrics and back on the tools??

    In that last photo - in the background - is that the output of the steering box in the cut out of the hull?

    I presume the final drive/reduction box is going to bolt over that?

    You have a shaft to bridge the "gap" across the hull to the other final drive/reduction box? I'm assuming the existing shafts are going to be "modified"/adapted to marry up with the steering unit?

    Evening,

    There's not alot to show you really, as i have been altering my previous work to accommodate the new, later engine. I took a trip up north to meet Rick,  Eddy8men and what a really nice chap he is. The reason for my journey, was to pick up the muff couplings for the steering box drive shafts but oh, how I would love to restore some of his toys. Thanks again Rick, for the bits and the chat.

    Whilst I was talking to Rick he introduced me to a new word " Imagineering" so I have been doing a bit myself. One of the frustrating parts of this project, so far, has been trying to decide what to do for the final drives. On the way home, being bored at the wheel, I was thinking about all the options thus far and it looked like I would have to sell a kidney to finance the relevant  components, then seeing a vehicle on the road and cursing a lot, I had an idea. A quick search on fleabay and low and behold, someone was scrapping such a vehicle  3 miles from where I live. I haven't done any accurate measurements yet but from a tape survey, they seem to match up, almost too exactly and the ratio looks to be 5.5 : 1. Sunday morning, my son and I, took a Land Rover stuffed with every tool needed for a right bugger of a job but ended up only using a couple of spanners, a ratchet, highlift jack and a big bar. Two hours later they were in the workshop waiting to be washed.

    So is this a pitch for the latest "Clives Mystery Object" - Yes they are final drives but off what?

    Chris,

    Thanks for posting these pictures. I drove this tractor (as well as its sister tractors 01HW87 and 01HW88) for over 5 years. On the one hand it is gratifying to note that after nearly 40 years it hasn't been scrapped, but on the other hand it is saddening to see the state that it now lies in - about the only thing recognisable is the identity plate and the grab rail around the roof of the cab! That lovely Perkins V8 engine looks particularly rough.

    I have looked out some more pictures of this tractor and the tractor that was evaluated during the trials. First picture is the bare 171 being delivered for testing on a DROPS rack.

     

    drops171.thumb.jpg.3605573d6c4a50727781ff3347aeb311.jpg

    Second picture is the final development of the 171 before production began. The picture shows a much younger me sitting on the tractor at Mullach Mor, the second highest hill on St. Kilda - the brief required that the 171 should be able to do every task performed by the Scammell Explorer which it replaced. The Scammell was capable of hauling a drawbar trailer up to the radar station loaded with 10 tons of hardcore for construction work so the Muir Hill had to be shown to be capable of doing the same or better.

    trial171.thumb.jpg.e81b2780b4e9f6044201bed040573142.jpg

    Next picture shows a brand spanking new 01HW86 being delivered (01HW88 at the front of the low loader and 86 at the back). In those days all vehicles were delivered by the manufacturer to CVD Ashchurch for acceptance before dispatch to the unit. Compare this picture with yours and you can see how badly the tractor has  had bits removed and deteriorated!

    mh171delivery.thumb.jpg.d9e0bf3e17ab7dbdb2f0a2d59ec8a1e3.jpg

    The last picture shows 01HW86 working the Landing Craft as it was designed to do.

    86working.thumb.jpg.adf67082f2e21da478f0d72d064fd157.jpg

    Finally, there is a Youtube video showing 01HW87 working on St. Kilda. I am not very good with links - if you go into Youtube and type in "resupplying st kilda" the video will come up (I am sure that someone on this forum will do the honours and post the link).

    Shame the video stops just before the man carrying trailer leaves the LCT!!!

  12. The rail complex serving the gun batteries including Wanstone are covered here:

    https://en.wikipedia.org/wiki/Martin_Mill#Martin_Mill_Military_Railway

    The additional link to the Cross channel guns has good photos of the various pieces of ordnance (and show rail lines)

    https://en.wikipedia.org/wiki/Dover_Strait_coastal_guns

    The lines were standard gauge as rail mounted cranes (those used for accident recovery) were the only means of doing barrel changes.

    The lines around Dover and up to Canterbury were used for the recovered/refurbished railway guns that had been held in storage after WW1 and pressed into service.
