      Hi Hindenburg

      Here's another snippet for the FN25, it contains actual measurements!

      Interestingly the turret is tilted from the vertical (assuming that the floor is horizontal), makes you wonder if this was corrected by the apparent 'nose up' flight angle of the Stirling.

        And using those dimensions - into the fuselage she goes! Still need to fiddle a good few parts

        I hope to show that perhaps these turrets may not deserve the 'always sliding out of the fuselage' reputation that they have.

          Wonderful...if only the real thing were so easy.I tried filling in the gaps between measurements and drawings with the brother-in-law doing the layout on the computer.The panel resulting from this would' fit it's space and the curve was wrong.The only reason he could come up with is the computer and human are different as far as the curve was not constant for a reason..and the instrument sizes must vary slightly where as his computer filled in the gaps logically...no..I don't know what he meant either.

            Easy? Blooming Cheek!

            I don't have many drawings, and fewer actual dimensions, photos are useful but can be incredibly misleading. I do have to jiggle and jostle the parts together for ages but at the end I still know that it's still mostly wrong. As you know the A/C changed constantly in detail which doesn't help!

            Still it's very absorbing and I'm enjoying the results!

              Hi All

              I've never seen a really good picture of the underside of a Stirling but modelling it is revealing what may have been there.

              Here is a comparison of the best MkI underside pic I have and a comparison with the model. The tail or fin is quite distinct and a common sight, the two black dots could be where the spent cartridges fall out - might be the gun barrel ends? The bottom of the footwell is less distinct but you can sort of imagine it.

              The black crescent defining the far section of the turret apeture is quite deep and shows that the turret was not 'flush' - the original photo must have been lit from below to produce this effect - that probably wasn't a common lighting arrangement I wouldn't have thought.

                So this is what it looks like close up - possibly the gaps were plated over but it would have been a complex piece of work. Unlike other dustbin turrets the FN25 doesn't have a big flange to act as a cover

                The turret drops through a circular 'I-girder' and so the oddly eccentric positioning must have been how it was. The shadow on the photo shows that the plating wasn't flush which seems to be asking for 'drag'. However, the girder seems to actually be two similar girders, one on top of the other so there would have been somewhere to put some plating and have a recess.

                Taking votes on the plating - or not!

                        Hi

                        As promised this is a link to an animation of the FN25. I don't think that this was ever filmed.

                          This animation shows what it was like to be a gunner in the FN25. Still loads of work to do on the texturing - but that's for later.

                          It's very hard to reproduce what you would actually see - It's interesting to note that human eyes can see through more than 180 degrees and in fact the edges of your vision is the shape of a big oval! Your vision is only limited by your skull! So I've widened the field of view to try and get to a human view, agaian getting that closer will be for later.

                              Hi Hindenburg

                              Thanks for the offer, I've got the bomb doors pretty much in place now, next items are the roof emergency hatch, and the rear gun ammo runs, the escape ladder and that ood step thingy for the crew to exit from the Astrodome - dimensions of parts of that would be great!

                              Cheers

                                  Thanks Turretboy

                                  Next set of images will be a walk up the back of the Stirling to see the many holes and items too hard to see on the grainy pics of that period.

                                    MkI - Mid Upper ladder pulled forward and pivoted down - hatch has been opened by the external handles held under the door in the fuselage next to the hatch.

                                    Nice day - crew off for a walk I guess!

                                        Hi Martin

                                        I've been diverted a lot by damp in a friends house and other building work - but I made a good fist of some new flashing I am pleased to say!

                                        Still working on a video showing all the holes along the top surface of the Stirling - met some issues with the way the modelling software smooths over the fuselage which involves a lot of 'fiddling' to get smooth.

                                        Added a request to you on your facebook page for some dimensions

                                        Cheers

                                          This is extraordinary - very well done James - a work of art and engineering.

                                          If you don't mind me asking, how is this done? What software etc? You talk about being able to trace diagrams/plans? Surely they are 2D?

                                          Many thanks, Don
