A week back to work after a nasty bug dropped me quicker than my last girlfriend.
Work is progressing well on the forward fuselage area at F11 being butted together.If you look closely in different pics you can see it is a bit different to the cockpit version.This is because of the difference in Spitfire versions.The cockpit section is more MkVIII but the one on the jig is pure early spit.You can tell by the internal top curve.The later versions had an internal "C" channel going up underneath the rollover structure (the top triangle shape) from lower down near the datum longeron giving the squarish curve seen.The early uses a smaller version and only goes down to the Frame shoulder coamings.Also note F8 has the horns cut off on the cockpit section,this again is more a MkVIII Frame.On the jig is the correct horney version.Think it has something to do with fuel tanks,fireproof bulkhead or instrument panel.More research needed.
Also Nathan has taken the blacksmithing route and fabbed up this marvelous pilots door crowbar.In 3 pieces with Steel ends and Monel (steel) rivets.
Another job which starts but isn,t finished was the aerial crossbracing between F12 and F13.Well on the way good and all.Channel is 2" and Lightening holes are 1.25".This has been designed off the GA drawing and one diagonal member drawing (thanks Geoff).The flattish parts are the templates,Cad drawings printed off full size and glued onto bits of tin.
Anyway getting late,real life work tomorrow :(
