First, Dave thank you for sorting the uploading. I now get a “awaiting moderator approval” message when I post.
I realised that W76 would need major surgery, so set about building a frame system to preserve it’s original shape. I started by making paper templates of each bulkhead and original building frame location.
Then added fingers to the templates to ensure maximum accuracy.
Once all these were done I built a substantial structure to keep everything in place.
This gave me a starting point. I had previously checked all of the original measurement certificate data points to ensure nothing had moved since 1960…..
