That's a proper job you've done with yours Alasdair and I shall try to replicate it as far as I can but less the alloy tape...
I've had loads of experience of this in the past through making custom foam inserts for transporting and operating delicate electronic instruments that lived in Peli Cases..
I have a Peli Case I use as my travel toolbox when out and about in Bluebell or even Polly if I think I may need tools...
Today's been a good day

We enjoyed a magical 2023 edition of the traditional Redway Runners Boxing Day muddy trail run... 7.5 miles designed to blow away the Christmas Day cobwebs and excesses...
This year it was gloriously wet and muddy

Just what I love in a run. As a runner I'm much more a small 4x4 rather than a sports model and I'm a better running in the mud than I am on the tarmac... Today I was one of the faster runners and had to run a mile more than some as I had to loop back so the slower runners could catch up...
Here I am talking to a friend as we summit a long muddly climb up from the river... We gained enough height to end up close to an OS Trig. Pillar...
Our run took us through Little Linford Wood. Here hangs an interesting tale. Nowadays it's an SSSI and has regrown over the last 40 years or so from almost scratch after being harvested for its timber. Back in the 1990s when the Channel Tunnel was being built it was necessary to relocate a colony of dormice from their Kentish home and the young Little Linford Wood was chosen for their new home. It was fenced off and nobody could enter whilst they and the wood re-established themselves. And they have, very well. The dormice even have their own little tunnels under the M1! Once again the wood is open but restricted to the public rights of way through it and on foot only.
The M1 also has big person-sized tunnels to maintain public rights of way. Amazingly, all these tunnels are totally grafitti and rubbish-free as they are just too remote and hard to reach from the conurbations... It's refreshing to see.
Looking at the gps overlay of our run on an OS map it appears we ran along the motorway! We didn't, it was just a small (normal) GPS error... A public right of way runs right on the edge of the southbound carriageway with only a flimsy fence to divide the two. It looks like we ran across all eight lanes of the M1 but we used the aforementioned tunnels!
After the run I went for a nice bike ride... It was too lovely a day not to
All in all, a perfect way to spend a Boxing Day
