Thanks for the comments guys!
So after turning the kit-engine to scrap I had to find a new ‘Pratt & Whitney R-2800 Double Wasp’ engine…
Since I have a 3d printer I decided to make the 3d model myself. To make it accurate I needed a technical drawing of the real thing, but to my surprise that was very hard to find… Eventually I measured the engine from a Tamiya kit (61090) and used a lot of reference pictures of the real engine to make up the 3d model. That took ofcourse a lot more time than I anticipated…
When the 3d model was finally done I could print it, I fitted 2 complete engines (middle), 3 spinners (left) and 2 oil-cooler inlets (right)…
The support-structure was removed, next I cleaned the parts with IPA and UV cured them…
I must admit it’s quite satisfying to look at parts you designed yourself, I’m glad I’m finally using the printer for what I originally intended…
Left: Some smaller support structures needed to be removed.
Right: The inlet for the oil-cooler didn’t fit properly, this was a tricky part to design because of the curved engine cowling…
So I had to adjust the part a bit with a file, you can see the adjustment when put next to each other (right).
The engine can still be improved with cables, for this I used the copper from an old LAN-cable…
I’ve seen some people here do the same thing and always loved the finished results,
I used superglue to attach the wire, then tried to cut and bend it into shape, which took a while as they broke off easily…
I cut a 2mm steel rod for the shaft,
I made the spinner in 2 parts so I can add a transparent disk in between, the idea is that the spinner looks like it’s rotating…
