Thanks Ed,

Yes, they are good!

I am just glad to have had some time to hit some metal (previous page) at last!!

Darryl, that detail with the frames is fantastic! Actually using rivets takes your build to a new level.

Thanks Ed,

I hope so, yes. Funnily enough, when I started this rebuild, I wanted metal but was looking to shortcut a lot of the building.
But it worked out that, in the main, the original techniques were actually quicker and better than my "fudges". They just required learning new skills.
I knew all along that I was not happy using pop rivets where they could be seen. The skin for example, has no interior walls in the Spit...so pop rivets would have shown the
broken off mandrel and squashed tail everywhere in the cockpit. Once aircraft rivets were decided upon and the technique practiced, most other "compromises"
were harder to do...

One example is the first attempt to make a frame by kerfing metal tube, then strapping the joins, then car bogging the gaps. That took ages, was not very effective.
So a bit of basic panel beating study later....proper frames. Now I have given up and will pretty much make everything "kosher'.

Not that that doesn't come with disadvantages when you are a pedant :)... for example...my beautiful new rudder pedals:

They will need stripping because the originals were bare metal sealed with a silver/grey protective coat. I'm also torn but haven't made a final decision yet, on the fact that first ones (my aircraft was only the 31st Spitfire ever built) actually used fire hose, cut up and rivetted on, for the "stirrups", not leather as these repos have. Don't you just LOVE trying to do things accurately.


There will be some compromises though. The skin will all be 1.6mm except for the fuel tank cover.. not the (variously) 0.9, 1.0, 1.2 that the real thing has. This will give a stronger skin, harder to dent AND add strength where you put your weight on the sides to climb in, at the cost of a little extra weight...not an issue for a simulator.

I am still however agonising over whether to make all the rear frames the same width as frame 8, as planned, or whether to give in and do that properly too..and deal with the compound curves etc that generates when skinning. I suspect I know what will happen .. ;) More time chewed up before flying....

i look at photos of mine when it was flying and photos of your P-51 now..and I am very jealous!!!

Sometimes it seems that I will never get to finish Frame 8. I injured my wrist last weekend and am not
allowed to bash metal for another week, so I cant do the forming that I have left to do
on the starboard side.

Instead I decided to have a go at a nice little piece that I have been eying off for a
while. I must say it was nice to get back to some detail work! So here we go.. the
Writing Pad Holder, specific to the Spitfire I. The II also had one but of slightly different
design. I didn't have a GA for this one so it had to be scaled from the available photographs.
Luckily the width is reasonably obvious from the throttle above it and whilst you can't tell
exactly from that one thing, the relationships between the three holes, the rivet spacing
and the throttle bottom only work within a 1/2 inch width between all of the photos and
drawings I have. On the biggest clearest drawing, a width of 4 inches makes all of the other
reference points come out to excat 1/4 multiples and the 4 inch distance between two of the
bolt holes up on the Throttle seems to fall into the top of the box if you draw perspective lines. I
am as sure as I can be.....

Next the Map Box or finish frame 8, depending on how I heal.

Darryl, sorry to hear about your injury.

Great job on the Writing Pad Holder! It looks great and how you determined the dimensions sounds familiar. I had to perform the same if/then for some parts where the plans were not clear or not available. When the finished part fits in with the surrounding parts correctly, that gives you a very satisfying feeling of accomplishment.

Take care
Ed

Cheers Ed,

Yes, the final fit is the worrying thing!! Perspective lines and near/far items make this kind of estimate a bit of a minefield...but in this case, the throttle being almost straight above and almost in proportion helps. I could also use the rivet and fillet screw spacings to double check. I have dry fitted it to the old wood cockpit but it is very rough as the camera control box gets in the way and the throttle is mounted slightly further aft than it should be...but given those limitations, it looks like a perfect fit.
