Hi everyone, I have already posted this gearbox in the Gearbox collection thread started by Didumos69, but now that I have finished the instructions (as promised@mocbuild101, here you are :-)) I thought it would be a good occasion to start a specific thread on this gearbox. I am currently working on a MOC which has this gearbox implemented (will start a topic for that one in the near future as well), for which I had some specific requirements: I wanted manual operation on standard LEGO 5+R configuration, but with a gearstick that would pivot in all directions from a single point (like in real car). Apart from that, I wanted a center console that was not more than 5 studs wide, so the gearbox had to be moved away from the gearstick. I took my inspiration by Thirdwigg's 6speed gearbox from his Cadillac ATS supersedan, Crowkillers 4speed gearbox from his Asassin X19 and the 5+R gearbox from Nathanaël Kuipers' Predator. I ended up mixing them all with some inspiration from the 42054 Claas steering mode selector as well. Note: the version in the instructions is using the new DGB driving rings and red clutch gears, they actually give a more solid build (when I shot below pic and vids I had already used mine in aforementioned MOC, so I converted it to the old rings and wheels. Works fine as well, just a bit less solid). Manually operated Direct operation special features: single pivot point for gearstick, linkage to gearbox, fits in 3studs wide center console number of gears: 5 forward, neutral and reverse Here's some vids (apologies for noob quality...) and the instructions: Gearbox in action Shifter linkage system in action Instructions PDF Enjoy and let me know what you think of it. -
Hello everyone, Let me introduce ma latest creation, a Jannarelly Design 1 at 1:9 scale. Jannarelly is a French car manufacturer based on Dubaï : https://www.jannarellyfrance.com/histoire. We feel a lot of Cobra Shelby or Ferrari 250 Testa Rossa design inspiration. It is a Neo-retro style : New materials on old shape ! SPECIFICATIONS : - Dimensions in cm (L x l x h) : 44 x 20 x 12 - Dimensions in studs (L x l x h) : 54 x 25 x 18 - Ground clearance: 1,3 studs - Weight : 1,3kg - 2 000 parts FEATURES : - 5+R gearbox - HOG (at the back) + working steering wheel - Openable cockpit canopy - Transverse V6 engine - Independant suspensions - Front axle: Ackerman steering, caster angle, steering radius : 55cm - Openable doors, front trunk and engine cover - And a cool stripe ! On picture below we can see elementary features : The HOG is connected to a gear reduction 8t/24t to enhance wheels rotation. Front axle has a positive caster angle. I re-use @T Lego one from La Ferrari : https://bricksafe.com/pages/T_Antonie/ferrari-laferrari The cockpit canopy can rotate to see interior details and give a better access to gearbox lever : The gearbox is a 5+R architecture like Shelby @Sheepo : https://www.sheepo.es/2013/10/ford-mustang-shelby-gt500-14.html. The main column is taken from @Charbel Volcano RS design. Ratios are : R - 1:134 1 - 2.1:1 2 - 1.67:1 3 - 1:1 4 - 1:1.33 5 - 1:1.667 Back 3D view below : Each driving ring (middle, left and right) has its own linkage (pink, green, blue). There is no "no back" system like @Gray Gear https://www.eurobricks.com/forum/index.php?/forums/topic/177499-how-to-6speed-manual-transmission-with-safeshift-system/ or NK03 gearbox design because too big to fit in. INSPIRATIONS : Nico71 : http://www.techlug.fr/Forum/viewtopic.php?f=5&t=9776 Jeroen Ottens : https://rebrickable.com/mocs/MOC-2927/Jeroen Ottens/alfa-romeo-4c-spider/#comments T-Lego : Charbel : https://rebrickable.com/mocs/MOC-9613/Charbel/volcano-rs-supercar/#comments CONCLUSION : It was a real pleasure to work on this car : design working and features implement were a good challenge !
