Saxon steamship | Preservation of the Dresden steamship fleet
Bricks-on-Rails posted a topic in LEGO Town
Dear community, Today I would like to advertise a campaign and present a MOC to you, which basically does not belong to my core competence, but which I nevertheless enjoyed developing very much. But now lets start at the beginning... In the middle of June one of my customers from Dresden wrote me a kind e-mail. He informed me that the Saxon paddle steamer fleet, which is the oldest and largest paddle steamer fleet in the world, is currently in economic troubles. Not only because of Covid-19, but also because of the increased low water in the past years. Locals, fans and friends want to support the association "Weiße Flotte Dresden (white fleet dresden)" with various activities. The idea of my customer was to create a construction instruction for a steamship model and to sell it. A major part of the proceeds were to go to the campaign. I wanted to help. I wouldn't call myself a real fan of steam ships, but after some research I was fascinated by these old heavy machinery, like the steamers on the rails. The problem, clearly, I had never built such a model before, but once my interest was caught and after choosing a suitable original, I started working on it. It gave me great pleasure to see the model grow, also the acquisition of new building techniques from the sector ships was exciting. But soon it became clear that a scale model would be about 1.5m long. This is of course way too big to make a instruction for private customers. So I designed a model in reduced size. I paid special attention to the recognition value by the colouring and the proportions. Various details were reproduced in the exterior and on the decks, but also in the interior. For example the steam engine, which can be driven together with the two paddle wheels by a Power-Functions or Powered Up motor. The model is built in minifig size. The individual decks can be removed individually and the interior can be played on. The instructions are available directly on our homepage or in our Ebay-Shop for 14,99€ / $17.99. From each sold steamship instruction, we pass on 11€ / $13. We support the crowdfunding initiative "Preservation of the Dresden Steamship Fleet", which was founded by Michael Hillmann. Further information about the initiative can be found here. Many thanks and best wishes Martin | www.bricks-on-rails.de Inspired by the steamship "Dresden" The lifeboat is also present The roofs can be removed, the bridge offers space for the captain There are several seats at the rear, the lower deck is not equipped. The view of the "steam engine" In the front saloon there is, besides some seating, also a small galley The ship is divided into individual modules The dimensions of the finished model -

[POC] Paddle Shifter Unit
Didumos69 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Scattered over the last few months I've been working on a proof of concept of an improved paddle shifter unit for the Porsche 911 GT3 RS (42056) that uses the stepping principle from Attika's stepper. After several redesigns I finally came up with something that I'm so content with - because of its reliability and sturdyness - that I thought it would not only be valuable as a 42056 MOD but could be of interest to other car builders too. Just like Attika's stepper this setup relies on the interaction with a 90 degree indexer. And just like the orginal 42056 unit it makes use of silicon bands to return the paddles. I tried to hide the silicon bands inside the unit, but that would give too much unbalanced stress to the whole shifting system. The operation is optimal when the bands are close to the paddles. About the operation of the shifters: Each paddle pulls a pusher against a central knob gear independently. When the central knob gear gets pushed over the 45 degree point the 90 degree indexer takes over and completes the 90 degree step. This completion makes the knob gear push the pusher outwards, which allows the pusher to be pulled back into it's starting postion by the silicon band. While being pulled back, the 5x7 frames to the sides of the unit (with their smooth sides facing outwards!!!) make sure the pusher is pulled back inwards too. The video shows a setup that mimics the situation in the Porsche, with the 90 degree indexer integrated in the gearbox. When combined with the indexer, the unit itself can be used in the original Porsche as is. Feel free to add comments or post (suggestions for) improvements. LXF-file here.
