  1. Found this yesterday.

     

    It’s also the closest the USN really got to the mythical “Project Rainbow”, where experimentation with teleportation was supposed to have made ships 'vanish into thin air' before reappearing somewhere else.

    So, what’s in a name?

    At first glance it seems to be what it claims. It was a ship under US command. Its aircraft bore the USN white star. Its crew wore USN clothing. Its radio operators spoke with US accents. Many of its aircrew also had those distinctive twangs.

    But the name didn’t match that in the USN inventory: USS Robin was supposed to be a minesweeper / ocean-going tug.

  2. Not seen any mention of this.

    From the BBC Lincolnshire news pages.

    The country's only Ministry of Defence firefighting museum has begun to move its vehicles from the home of the Red Arrows to a new site.

    The Museum of RAF Firefighting at RAF Scampton, Lincolnshire, closed as space was needed to organise an airshow.

    The museum had a presence in Scampton's hangars for about 14 years and shut in January.

    Some of the 50 vehicles left for a new site about 16 miles (25km) away in Gainsborough, due to open in 2018.

    I have done large commercial tyres in the past at the roadside but suggest this is not for the fainthearted - if you havnt done this type of tyre before go to your local friendly commercial tyre fitting person and let them do-it (in a cage) for a small fee taking note of how its done  - then decide if it's something you really want to do as flying locking rings can seriously spoil your day for all time 

    When we were asked to change a number of tyres on our MK's we always took them to the Base tyre bay on RAF Bruggen where there was a cage.

    An added incentive was the couple of holes that had been caused by rings coming off and going through the roof.

    Make sure you never stand in front of them when inflating always stand to the side.

    Iron welds beautifully...but there's rules to abide by 

    For a start it's difficult to know what grade of iron you have...particularly with older items...or items from minor foundries and obscure manufacturers that often just threw any old crap into the cupola... 

    Secondly the long term effects of hot & cold...hot & cold effects iron on the molecular level...this can make it difficult to weld with an argon set... 

    Thirdly is the issue of thermoshock... Iron generally only allows for about 5% movement during heating & cooling...which can manifest itself with cracking on large surfaces... 

     

    In your case a good move would be to prep the area to be welded first by identifying points where cracks end...and drilling at a point just beyond (this prevents the crack from creeping)...a narrow Vee prep to cracks (both sides)...and the usual support during welding...  

    You need a DC stick welder and a pack of 2.5mm nickel rods... 

    Go DC electrode negative for welding the root...and then put the welding plant into DC electrode positive for capping the root weld... 

    You'll need a bucket large enough to put the welded part in...and some kiln dried sand... 

    If you have access to a coke forge you can get an even pre-heat on the part to be welded...and also give it a post-heat after welding before chucking it in the bucket and covering it with the dry sand... 

    An alternative to covering it in sand would be to keep it in the forge and gradually reduce the heat over a given time...

    Or tell her indoors you've allocated her £100 pocket money allowance to go buy herself summat fancy with...once she's out of sight you can use the oven in her kitchen to gradually pre then post heat the casting... 

    Thanks for that.

    The stove is actually a bit big to fit in her oven, so that options out.

    Thanks for the feedback regarding the colors, we will be making some changes to it early next week.

    Thanks for that.

  6. Recently saw a newish 66 reg  RAF operated Citroen van and noticed the tyre pressures painted on the wheel arch as usual.

    The rear ones are no problem being marked as 60 PSI

    However the front ones would be a test to get exactly right, being marked as 59.3 PSI

    Why?

    Is it a conversion from BAR pressure ?

    In that case why isn't the rear pressure similar.

  7. Nice job you and the team have made of the upgrade.

     

    Couple of comments.

    It appears very bright to my eyes, could it do with a tone down?

    Also Where has the New Posts button gone? Or is it hiding under a new name?

     

  8. It would appear that a facebook account is needed in order to watch the video.

     

    I found the same problem.

     

    It is possible to view FB sites IF they are made viewable but many are not.

    When a number of my colleagues who are working in IT all the time go to FB then I may register but at the moment they stay clear.
