Looks very good like this. Considering how tiny the cockpit opening is, and the fact that the seat plank will hinder any line of view continuity, I'd "rest on my laurels" and leave it as is ;) .


hey, I am getting better at it this time, am I not ? No extra-work-inducing remark :) ...

Much better Hubert, you are the conscience sitting on my shoulder  :beer4:  - There is also some piping for the coolant out to the wings which should also help disguise any optical kinking.


On with the seat... The kit supplied seat now wouldn't quite cut the mustard size wise plus I also wanted to see it I could improve on the refinement of the cast metal original. I faced the problem of creating a miniature a block pattern quilted leather back rest with covered buttons  :blink:


My first attempt of drilling and carving into a thin rolled slab of set Milliput did not turn out great - all four times i tried it....  :deadhorse:




I realised I needed to get the grid of the buttons absolutely spot on or it would not look right. So, starting with a slightly oversized sheet of 60thou plastic sheet I started to try and punch out a grid of 6 x 6 buttoned sized holes (0.5mm) with my punch and die set. Try as I might, even using every trick I could think of I couldn't get a perfectly aligned square grid of 36 holes - it only takes one hole being the merest fraction of a mm off in any direction to ruin the whole effect. 


Drilling came next - I do not own a vertical drill stand, let alone one with an accurate way of moving the bed by set increments so all my attempts with a drill would have to done by hand/eye. I finally figured out a way to do it by again taking a a slightly oversized sheet of 60thou plastic sheet and carefully scoring in a square grid of the right size with a scalpel - this again took four attempts to do to the standard required but once all squared up I used the point of pin held in a hand vice as an awl to mark the centre of each crossing point.




Using these as a start point I hand drilled each hole with a 0.5mm bit. 


Using the scored grid as guide the next stage was to very carefully start carving out the pillowed shapes of each grid. This was done very carefully with micro chisels, dental burrs both ball and cone shaped, files and a small curved scalpel blade. The key to doing this evenly and well was to use good visual reference, go at it very slowly repeating each very minor filing, burr twiddle/turning, scrape of the scalpel, over the whole of the area before repeating if needed or stopping and moving on to the next process. Everything done b hand - if I'd have tried my dremel even on it's slowest setting I would have easily ruined it. 


Once happy with the shape I painted on a touch of liquid glue to dissolve any remaining plastic waft and dust as well as help soften/round off any remaining micro facets.






More in a mo,

I first tried using 0.5 mm rod for the buttons but felt these were a fraction too small so after using a very fine reamer I adjusted the hole to perfectly accept some 0.64mm rod.






Once all 36 rods were dry fitted, I trimmed them reasonably close  and then  used a beading tool to push them to exactly the correct dept.




With everything in position I then glued from the back... Voila!






The effect of the buttons is much more subtle in the flesh than under the intense side lighting shown here - the buttons are clear but subtle, set in shallower than the plumpest section of the surrounding square despite the optical illusion that they're pretty loud and proud  - very hard to shoot. All turned out exactly as I wanted... Phew!!!


The final stage in construction was to trim and carve the edges of the cushion so that it fitted within the tight space, taking care to replicate the small pleat line between each section of rows of buttons on the edge. I also imparted a very subtle curve to the shape as indicated in the plans I'm using as a guide.






Thanks for looking - next stage on with the central structure of the cockpit.

Gosh - thanks all for your kind words :D A few too many to reply individually this time as I'm a bit rushed but always great to read! I enjoy the challenge of working new (to me) things out like this.


Time to fess-up to a ‘senior moment' - whilst test fitting the seat I was concerned that the fit was super tight on the sides until I checked again against the plans and realised I'd done one too many rows of buttons - there should be 5 across not 6!  :doh:  Fortunately the solution was to simply trim one row off and carve the new edges to match. - I'll share some pics when I've sorted out the framework.



Hi Torben, great work! I was always puzzled by the three 'black holes' below the LE of the wing centre section, then I ran across this picture - I have never seen it before, and thought you may find it useful.




Thx Malc, what a great picture - I thought I'd scoured the net for all the best images  - can I ask where you dug this out from and if there were any others as the detail is so good?


I'm not 100% sure what those holes are but my best guess is that they must be circular inspection hatches with their covers removed. Some radiator coolant pipes are around that area of the wing root. The whole plane plane is dotted with circular inspection hatches, especially the floats. 


Some pics in a mo along with a question that I'm hoping someone out there can help with.

I've just started working on the pit properly  - As I've yet to find any photographic images of the S5s cockpit I'm basing all this on a couple of images of the S6 (previously posted) and this plan (again previosly posted but low res.




I managed to make pretty fast progress after finally I worked out that the two pipes heading from the coolant section right by the firewall didn't run inside the cockpit but outside the monocoque within the wing root faring (or at least i hope it is as that's where it ended up  :innocent: )




I wanted to get a variety of appropriate scale thicknesses so brass slim came on handy for the footplates which were not bowed in on the S6 so I copied here




The rest is just square section rod and thin plastic card with lightening holes knocked out with RP Tools my punch and die set - I trimmed out and punched both sides at the same time to make sure they were identical and even.


The foot controls came next - the grip texture created by dragging the teeth of a micro-saw blade sideways across the plastic card.




Then I started on the joystick which was made out of brass rod that was shaped by mounting each piece in the chuck of my mini drill and turning/lathing it against a various fine metal files. The elevator rod attachment was made out of sections of brass tubing with  the end trimmed to form a yolk join - the 2 securing nuts made out of punched thin plasticard.






I've still got a little way to go but I'm having a lot of trouble trying to interpret the plans regarding the detail where the main pivoting ‘knuckel' point of the control column is shaped and joined to the cockpit frame.


All looks like this at a dry fitting stage with the pivot point should be about 2-3mm above where the column rises out of the frame.






But when one adds the main central rods (I've interpreted these as structural extensions of the rods within the rear legs down to the floats - anyone care to differ?) when I position them inside they look like they might foul the control column in reality...  Similar such rods seem to appear on the S6 but if the central box structure appears wider on that plane




If fitted outside the central structure then they'd likely be in the way of the pilots legs?




Hmm - any thoughts?  :help:    Gut feel says inside. Could the pivot joint of the column actually be attached to these rods, between them as they cross over in the vertical plan?


I could really do with some help from you more experienced crew out there - a best guess as to what is happening in there, not only at this point but also some of the other detail around this area - the aileron controls are a little fuzzy as are what appear to be 2 cross bars(?)  - one just behind the column, one level. Even just a quick 3/4 view pencil sketch would help.... 


I'm pretty sure I've got a handle on the missing foot control levers but again, a light shed in this area too would be much appreciated. 


Thanks for looking
