How things change….exciting times Not in any way, shape, or form... And the thought of scratching that tiny engine to the level of finesse I'd have wanted was giving me nightmares - which is why I kept putting the project to one side. I feel hugely empowered now - with my resin printer for detail partes, and my FDM printer using HIPS, i can make almost anything - a very liberating thought as there are so many things I'd like to do! I was going through a bit of bad time when @wunwinglow (Tim Perry) of this parish introduced me to 3D print and design - and it's been great 'therapy' and a wonderfully positive journey (mixed with a fair amount of frustration) to get to this stage. Very rewarding and exciting! Still a lot of learning to do, but I feel I'm starting to get ahead of the curve at last.

Hi Malc, I'm afraid I can't remember the source of the drawings - was such a long time ago - I think they were the result of some googling at the time - and checked against lots of photos - which has meant several steps back at times to change/correct what I've previously done.

Thinking about it, the build will span some of the very early scratch building techniques using plastics and balsa - through to the latest digital tech for paint masks and detail parts. If I were to start again I'd probably create the whole airframe as a CAD model - so, for me, this project will probably remain unique in the way it's been tackled. Interestingly - my choice of finishing materials have moved on by a margin too - with the final colours being Xtreme Metal and MRP - which I hadn't used when I started and are now my 'go to' paints.

Iain Posted March 18 Author Share Posted March 18 Further progress with Fusion 360 - coming on leaps and bounds now! Bear in mind these designs are simplified - they are small in 1:32 so any smaller detail won't print well, or be seen! All now printed and painted - look really good - but haven't had a chance to photograph yet. Engine is printed as 6 separate components. And this took about 10 mins to draw up - basic, but does the job! A few more parts to draw up - but might, actually, finish this shortly! @wunwinglow - you really have created a monster...

Archimedes Posted March 19 Share Posted March 19 Really enjoying the CAD work there Iain. Fusion 360 clearly is a decent tool and you use it well. Kind regards, Paul Iain 1 Link to comment Share on other sites More sharing options...
Iain Posted March 20 Author Share Posted March 20 I promised to post some progress photos, so... 3D prints from the CAD models above - in basic paint - some detail work to be done, and some washes: The 'cowl' on the left has been made using the more 'traditional' route of hand carved master and vacuum-formed sheet. Old and new technologies in harmony... One thing I'm *really* chuffed with is that everything is so precise it all clips together perfectly - and stays together without any glue! Prop is a 3D STL scaled to size and printed - more detail paint to follow: Basic seat - all that's needed: And the wheels, tyres and undercarriage legs assembled: There's more - back shortly...

Shoggz Posted March 20 Share Posted March 20 Very nice. Iain 1 Link to comment Share on other sites More sharing options...
Iain Posted March 20 Author Share Posted March 20 Undercarriage slotted in place. The legs were printed hollow - vertically, as well as horizontally for the wheel axle - and 1mm diameter brass rod bonded in place with cyanoacrylate glue. There's a section of the brass rod that sticks out at the top - this slides into holes drilled in the wing: Yay - it's worked! And the model sits nicely on them when flipped over. Need to draw up a tail-skid. Iain Landrotten Highlander, Shoggz, scvrobeson and 3 others 6 Link to comment Share on other sites More sharing options...
Iain Posted March 20 Author Share Posted March 20 Had a play earlier with the main elements held together with small blobs of Blu tack to see what the overall effect is... I've tested some MRP gloss varnish (a lacquer) over the Xtreme Metail 'White Aluminium' (enamel) to see if there's any reaction - and all good! I normally let paints dry for a good week before other paints anyway. I didn't post photos after I'd added the registration, using masks drawn up in CorelDraw and produced on my Silhouette digital cutter - came out well, but the Oramask film did leave an annoying residue... And the main assemblies 'dry fitted': I'm quietly pleased with the overall look at this point - I've tended to overthink things all the way through this, but the last 4 months it's been a great incentive to get to grips with Fusion 360 software - the engine, exhausts and wheels would have been difficult to scratch-build cleanly - and impossible to do to this standard on components so small! Dart Aircraft logo now drawn up so that I can print a decal - so that, and an overall gloss coat are next on the to-do. Following that some more parts to design in CAD. All *very* rewarding and helping to restore my modelling MoJo. Have fun! Iain LSP_Kevin, scvrobeson, Landrotten Highlander and 2 others 5 Link to comment Share on other sites More sharing options...
