1/18 P51C Mustang "Lopes Hope the 3rd"

Great progress. I don't think it's a shame all of this is going to be covered with paint. I think when it's painted you will still see it's a metal skin and that's very nice.

howdy folks :)

 

..just a little update as not had much time this week..

 

you can see here that where the skin panels on the fin & stabilisers end, it drops down to the bare fuselage shape - this is a problem for adding all the fillets around this area as when you burnish soft metal to get the complex shapes of the fillets, if it stayed like this, the fillets would distort where the existing skin ends and would form ridges...

..that means all that area needs to be filled so the surface onto which the fillets are added is perfectly flat - even a seam line can show through..

 

..the first step is to get a tape template of the missing area and cut a sheet of plain annealed litho to go there..  here this bit covers that area and the side of the tail fillet...

..then it is stuck & burnished and all the seams filled so it is one contiguous surface..

...I also skinned underneath by the tailwheel well..

..the fillets will come next and be quite involved - I only have drawings for the early P51B version without a tail fillet..

..you can see how they sit on top of the aircraft skin..

..and I have some good photo's of the fin fillet to work from.. - just need to unpick the order they go down - this fillet will be added later as it goes over panels I won't add until the cockpit is in place and the rear canopy are is built up..

..back soon with more..

Yep, this is one of those threads that can give hope as to what is possible, yet give despair to us mere modelling mortals that we will likely never achieve anything like it.  :lol:

Just love every update Peter!

 

You spoke about overlapping the leading edge sheet to make sure everything lines up; do you do this for all the panels or is it more just those tricky ones and due to the softer material you're using on the leading edge that you do this?

 

Awesome as always!

Hi Craig - I only do this when using annealed litho, or the soft ali I use for compound curves - a good example of this comes in a minute when doing the stabiliser fillets - it's a really good way of getting a virtually invisible seam rather than trying to butt two complex edges together..

 

So, fillets....

 

they are all curved as you woulkd expect, some in multiple directions - I was hoping the dorsal fin was the last panel as the very tip of it overlaps the fuselage skin I can't add until the cockpit is in.. but no, it's the first panel down - I guess as it's the least removed in service..

 

..to get an idea of the area, this is for a P51C without a dorsal fin - I couldn't find too much on one with a fin and all the resto pics I have of Lopes Hope do not yet have all the fillets fitted so some assumptions were made from what I could see that they are pretty similar to a 'D' model..

 

..you can see curvature & shapes and the fittings that fasten them too

..I did the dorsal fin but forgot to take pics, so this is the upper forward fillet first..

 

..a sheet is bent & taped down to start the forming process..

..a ball pein hammer is used to gently beat it into shape, and helped with balsa rubbing blocks and hard wood coffee stirrers..

 

..here I am trying to get it to conform to the leading edge and the curved part that runs out onto the fuselage..

 

WIP770_zpsisy8vczr.jpg

 

..after shaping a number of scaled templates were used to derive the shapes - these are side views so I have to allow for the shape as it curves away from the eye..

 

WIP774_zpsbm8fm9i5.jpg

 

..and soon all the fillets were in place ready for final shaping & smoothing - at the leading edge you can see where the panels overlap - by sanding away the overlap a perfect seam results - in fact on the full size one this is a butt weld which is finished on the outside..

..after final finishing and finessing some of the edges, the fasteners were added - this was a vet labourious process as each one must be punched, then marked with an awl for the fastner, then flattened, then added - there are about 60 each side..

..once the other side has it's fasteners (I can only do so many at a time without getting bored..), I will move along the underside to the air scoop & exit under the fuselage..

Looking mighty fine there Peter - masterful stuff and, as ever, it’s a genuine, inspirational joy to follow this build.
