The updated version of the model provides very basic, drum shaped wheels. Not really to my liking so I have been experimenting a bit with the preparation of the wheels. for as far as time permitted.

Ricleite was so kind to send me his "tire-files" last year and finally I could have a more detailed look at them, trying to understand the mathematics. I simplified the maths somewhat and used different qualities of paper (80 grams, 160 grams) to prepare a try-out of the wheels.
It's probably been the lack of sufficient time to practice this new technique (at least for me it is) but I wasn't satisfied with the result. The wheels appeared rather bobbly and unevenly and eventually I decided to use the sliced approach, by making concentric circles and to create the 3D looks. For the size of the wheels of the DC-9 this is good enough for the moment but I'm going to practise more on the "rolling method" as it is a very good method and I gained some interesting experience I would like to share with this community one day.

Let's not bore you too much with the details but here's the result of the main landing gear. The core of each wheel is made up of 2 layers of each 0.9mm thick cardboard laminated on either side with 7 (concentric) circles of 160 grams paper of 0.2mm thickness, resulting in the required 4.6mm overall thickness of each wheel.

The pictures reveal some of the process and the first one shows the various types of wheels I considered/prepared (from left to right: drum type as per the model; rolled up by using 160 grams 0.2mm thickness; sliced 160 grams and unfinished rolled up using 80 grams 0.1mm thickness).

I lightly sandpapered the end result to round the edges and painted them in Tamiya Rubber Black.

The axles consist of rolled paper reinforced with a metal core, diameter 2mm.

As mentioned before, I had to glue a small weight (two M12 nuts or something) in the forward luggage bay to prevent a tail strike .

Well, it's been a long story after all. Next time the model will be finished.

Cheers,
Erik

they look great.thanks for the tips

I got to say this is one really good looking model! The model design is perfect, the craftsmanship of the builder is outstanding and this topic viewer (myself) is amazed. Kudos to you sir for a fine build indeed.

Thank you Southwestforests, Alan and Falco .

In the mean time the job's done. Finalized the nose gear in a similar fashion as the main wheels. One thing I forgot to mention last time is that after lightly sanding the wheels I applied white glue with a flat brush as a coating to the laminated tires before (after drying) painting them. Overall this gives a better finish.

Then the doors to the main landing gear bays, antennas and minor corrections here and there, especially at the lower ends of the engine pylons to cover up the narrow gaps between pylon and fuselage.

As a finishing touch I added the static wicks at the wing tips and vertical stabilizer. Found these details on a DC-9 cutaway drawing and thought it would be a matching feature to conclude the construction of this magnificent model.

One final note: I think having mentioned it before but I slightly reduced the scale to 96% in order to match the original letter size onto A4 and to get everything printed properly. So the actual scale is 1:75 rather than 1:72.

Pictures of the final model will follow shortly!

Cheers,
Erik

The added details of the static wicks look great and really add to the model. I appreciate the tip about the white glue on the wheels. I'll give that a try.

Thanks,

Your accuracy makes me jealous, Erik.

Eastern is now boarding flight 100. Absolutely incredible job building this one.

[Erik Zwaan]

As promised as final contribution to this thread herewith pictures of the finished model. Indeed, Eastern Flight 100 is ready for departure!

Thank you very much for your interest shown and flying along: Joshuajaeseo, Yoav, Eatcrow2, Richschindler, Gary/MacSongLi, Wad Cutter, Alan/Herky, Ronan/Ofanim, Papermate, Don Boose, Dhanners, Dan/Smithdr, Missileer, Combide10, Isaac, Knife, Saybur, Cafe, 7TP, Southwestforests, Falco and Abhovi. Hopefully I didn't miss out on anyone.

Alright, my desk's been cleared and cleaned - time to resume and conclude the A4 Pacific Sir Nigel Gresley. Hope to see you there again.

Cheers,
Erik

That is just amazing! I love the way it turned out. That fuselage is so smooth as well. Great job!
