I think anyone who ever used the portal hubs came to this issue. The hubs simply have the steering pivot point so far from the center of the wheel, that you need to either reduce the steering angle, or have a model with large fenders. Today I came up with this simple mechanism to compensate for that by simply turning the whole front axle in the opposite direction. The two tilted 6L links are usually used to keep the axle from moving forwards/backwards. In my case they are attached to the steering rack at a high angle. Moving the steering rack will cause the geometry of the axle to change - rotating it to (mostly) compensate for the large pivot point: Of course this is just an idea for now, but it should be easy to implement on a real model. The wider the axle, the better the compensation. Of course the axle has to be designed in such way, that suspension, drive and steering system will be able to work with this degree of movement.
This model is a modified CREATOR set called Lighthouse Point. (set number 31051) I removed the light-up brick and as such changed the top of the tower, along with tweaking the inside details and adding a custom Lighthouse keeper out of 1990's mini-figure parts. The model has modular parts out the wazoo, with a whopping 10 building sections. (their was one one more module from the set, but I removed it before taking pictures.) The set also comes with a killer whale / orca. You may have also noticed I had a bunch of trans - yellow bricks from a Classic Space build left over. They made a good replacement for the light brick. The inside features a table, lamp, and mounted instrument from the early days of sailing.... though this device measures where you are via the sun, so what is it doing on a stationary lighthouse? (The yellow chairs I added myself, along with the red soda can.) The set contains 10 modules as follows, (in no particular order): Tower top with light, building roof, building proper, small dock, exposed small rock, exposed large rock, tower foundation, two red tower modules, and a white tower module. This cute critter comes with the main model of set 31051. His flippers move, his tail flops around, and his jaw opens to swallow fish.... or unwitting swimming mini-figures! Thier is no LDD file for this build, but it shouldn't be too hard to recreate what I did, right? Comments, Questions, and Complaints welcome!
Hi all, I've been playing with some ideas for remotely switching my tracks. Here's a link to the 'proof of concept' mockup I've made of my progress to date. It's very much cobbled together, but I think it will work on my layout, to give me remote access to distant points. Its not a 'pure' lego solution, but it's unobtrusive and relatively cheap. This requires modification of: - The point (to remove the 'click' when the track gets switched - there's too much resistance for a small servo to overcome). - The lego 'cupboard' (to fit a small servo inside, and cut a hole in the door.) I tried modifying a small brick, but the servo was just a fraction too wide. The cupboard seems to work well. The only wiring visible in the final layout will be three very small wires running from the cupboard. I'll put together something more detailed once I have a version installed and running, if anyone is interested.
