04/10/2020 Update
... and this is an update with a very different flavour. A distinctly Jet Provost with a hint of salt and aluminium oxide kinda flavour. And I must say, it's really not a very pleasant flavour at all. Dear Reader, prepare yourself for an early Halloween horror story...
As you may be aware, for a number of years now the museum has had a nice little Jet Provost on display, T.4 XP640. She is WS788's hangar neighbour. She has recently been joined by a second nice little Jet Provost (because JP's are all nice little sweet inoffensive things aren't they?), the ex RAF Linton On Ouse gate guard T3A XN589. 589 came to us as part of the sad closure and winding down process of Linton on Ouse, she was dismantled and roaded in with the idea that she would become our YAM gate guard. Firstly though, despite being in very good external condition, there were a few minor issues to address before she was ready for reassembly and display. So, with her wings on our ex-RAF Jet Provost wing trollies (formerly home to 788's wings a long time ago) and her fuselage bolted to a specially made wheeled cradle, the JP kit of parts was wheeled into the HP building for what was hoped would be a bit of minor sprucing up prior to going on display.
Then, COVID-19 happened. Sadly this has meant pretty much everything has stopped on the old girl. We do need her mobile though, and on returning to engineering activity at YAM I was asked if I had a spare minute could I take a look at her and see if I could work out why the nose leg was fully compressed and more or less locked in the fore and aft position. As if I have spare minutes, no lounging around on the grass sunbathing for me! Anyway, I took a look, and as the nose doors are shut could see very little. A bit of homework showed the doors should just pull open. Nope. Not only would they not budge, I was getting regular and displeasing little downpours of sand from in the doors. This is never good. I assumed the RAF had done what the RAF had always done, and ballasted her nose with sandbags. So, I did the right thing, and pretended I had seen nothing and walked away, kicking the little pile of sand out of sight! However the JP wouldnt go away, or fix herself, and we are getting to the time where we need her moveable. So this weekend she shuffled to the top of my priority list for now. Yes, I know, I have cheated on 788. But she's in a different building, pointing the other way, so I'm hopeful she won't find out...
I decided the only thing to do was to start at the top and work down, as the structure of the JP nose doors doesn't lend itself to drilling skins off and attacking it from the outside in, and the less disruption I can cause to the paintwork the better. I know if you open the bonnet, you can get to the top of the nosewheel bay, remove the top skin and drop in on the nosewheel from that way. Also, I had a feeling something nasty lurked in the nose bay, something which really could not be ignored. So, deep breath, drill off the riveted patches over the nose latches fitted in 1992 when she was allocated as the gate guard... and open sesame. The nose latches cooperated perfectly after just a sniff of WD40, a good sign. I cracked the nose open with a squeak of protesting hinges, and was met with a smell of damp and decay, a bad sign. On opening the bonnet fully, the sight of the remains of 3 hessian sandbags greeted me, draped over the equipment racking and the radio rack. Great.

After letting it ventilate, I set to dragging out the remains of the sandbags. I tried to do this keeping them as intact as possible, but the bags were already burst and, as will become apparent, had been for some years. None of this explained the sand in the nosewheel bay. Where there more bags in there, and the doors riveted shut? I would have to get digging and find out. No mean feat, and the further I dug the sadder the old beast looked

Some things soon became apparent. The reason the bay had been so wet was because nobody had refitted the join in the nose vent ducting all those years ago, allowing the water to pour straight in...

Saturating the sandbags which had, as I dug further, revealed the horrific damage this had caused to the old girl

Including in the above shot, how the nosewheel bay was so full of sand. The years of sand and water had rotted directly through the roof of the nosewheel bay, causing the whole highly corrosive mess to cascade into the nosewheel bay and doors. I own bits of HP Hampden bomber which have been in the North Sea for 70+ years, and they are nowhere near as rotten as this poor old machine

Only thing for it was to keep digging and hoovering.

Next job was to remove all the equipment I could, with a view to repair and reuse in bringing our other JP back to life.

Amazingly many of the bolts and all the terminals undid just fine, a testament to their quality

Someone has been here before!

Wrestling the oxygen bottle out was great fun...

Where it had sat was not happy at all though

Once the rack was out, I stuck my endoscope down through the rot holes to see what lay in the nose bay. The top of the nose leg...

The door close mechanisms...

...but fortunately no more sandbags!
Then, I sat down for lunch. She was watching me....

Wonder who Vince was?!

all the equipment racking had to come out. This was way beyond repair and reuse, so I didn't have to be too gentle...

Then it was time to make a quick offering of Lemon Drizzle Cake and tea to the corrosion Gods...

Before breaking out the drill and removing the nosewheel bay roof. This all went smoothly...

Revealing, again after sterling work by the hoover, much sadness within the bay. The rear wall of the nosewheel box is rotten, one nosewheel door hinge is rotted away completely and 2 more are very severely corroded, the door mechanisms are seized solid... its just a mess.

So, I did the only thing I can do really, and doused every moveable part in oil

This will be repeated over the next couple of weeks before I even consider trying to get the doors to move, as I don't want to cause any further damage. She's going to need at least the starboard side and rear of the nosewheel box removing and replacing, a new top piece making, the rest of the nose interior decorroding, treating and painting to stop the deterioration going any further, there's a long way to go yet with her. but... the worst of the rot is gone, the cause of the rot is gone, so hopefully the future looks much brighter for her

This, here, is where the graft happens in aircraft restoration and preservation. This is the coalface

And I'm bloody proud to be able to get my hands dirty and do this!
I did of course go see 788

Last weekend was all about her, as next Sunday will be apart from blessing the JP's nose bay with more oil. Here's a reminder of what a JP nose bay should look like!

Not this
One final piece of business, The Saga Of Foxy Dave. Kelvin again broke him out of his prison on Saturday... Then promptly left him unattended by the side of XN974 yesterday. Well, what's any self-respecting Meteor fettler going to do when presented with such an opportunity...? All I'll say is...

...I hope he's not afraid of heights!!
