Hi, I am working on an update to my first Lego ideas creation and would like some help or suggestions as to how to create a flat top to a wing shaped surface. I would imagine that it is similar to an aeroplane wing except that it needs to be flat. My project is the James Webb Space Telescope that has foil type layers for a sun shield. As can be seen in my model, I have managed to get the shape but lack the smooth surface. Higher resolution images (and a video of it unfolding) are available on the Lego Ideas site of you need them. https://ideas.lego.com/projects/05fb57ff-a8d9-4795-8408-32d9e2114dd1 Any suggestions appreciated.
Hello there! I ran into a small problem recently. I'm trying to synchronize a couple of pneumatic cylinders which are not connected directly to the same frame and they keep extend and retract at different speeds. The hoses are exactly the same length and the cylinders are from the same batch - they are not old+new. But even if I get the synchronization correctly then one of the cylinders does a harsh or abrupt action. For example when the pressure in the system is rising one cylinder starts to operate right away and the second cylinder is "stuck" until the pressure is high enough and it extends abruptly. I've spent couple of hours manually extending and retracting cylinders in order to make them work smoothly without success. Did you have such problem and if so - what was your solution?
