Something for the silly season

Well Watson - what do you make of this?

Good Heavens Holmes! It looks like the wreckage of a couple of F84s

Yes, I believe that some idiot has pulled apart an F84F and is going to mate the wings and tail to an F84G fuselage to make a model of the prototype, the YF84F

Why on earth would he want to do that, especially at this time of the year when there is a garden to be looked after, airshow photographs to process and a loft full of perfectly good kits to make?

Maybe its the heat, Watson, it does strange things to a man's mind and remember he's just finished a Mach2 Leduc 022. That can't have helped.

Does he realise that by starting from an F84G he is going to have to either make a new canopy or polish the frames from the existing one?

Well, as I said at the start, he must be an idiot

Will he succeed, watch this space but don't hold your breath

John,

FWIW my friend Bill Dye did what i consider one of the first kit-bashes of a jet. He combined the Italeri and Hawk F-84 kits to make a YF-96A prototype (Or is it the YF-84F? i can't remember). Its over on Hyperscale. Perhaps it will be of help. I know Bill is also working on a YF-96, as he's slowly closing in on doing all of the Thunder planes.

Cheers,

david

Actually it's both 96 and 84.

It started as the F96 but got changed back to F84 for budgetary reasons, I believe, causing problems as the F84G with straight wing came after the F with swept.

Thanks - I will se what I can find on Hyperscale

I thought that this would be a comparatively simple task but...

Things went wrong almost immediately. The donor wings were warped and were not responding to hot water treatment so I thought that I would try dipping one briefly in boiling water. DISASTER! It buckled and whilst I was able to get it back into roughly the right shape lots of milliput was required to rescue it.

I then discovered that the F84E canopy was not suitable as the prototype F84F had a Vee windscreen. As if this was not enough the wings are lower on the fuselage than the E.

At this point I put it away until I was in a better frame of mind.

On picking it up again recently I came to the conclusion that the wing planform was not correct and that the chord at the tips had to be increased and then discovered that one wing was shorter than the other - it must have shrunk in the hot wash so a little was added to the root. These additions can be seen in the photo.

To lower the wing position on the fuselage I made a box into which I could fit the existing wing tongues as this looked to be the best way of getting the wings lined up and providing a secure fixing.

Now for the canopy. I made a mould by lining the F84E canopy with Micromask and then filling it with Milliput. Much to my surprise I was able to extract the filler. The plan is now to add Milliput to the forward section and sand it to the correct shape.

No I didn't contact Bill. His article covered most of the things I wanted to know.

I have just re-read it because I could not remember him saying anything about the wing position apart from the fore and aft alignment.

I have just looked at a 3-view and some photos of the straight wing F84s and it appears to me that the Heller kit does not have the vertical position of the wings correct. I wonder if anybody has any views on this.

I thought Bill's model looks OK as it is. Why do we let things like this bother us?
