Here’s a sketch of my new, exactly 5-wide boiler design. Characteristic elements are: the "backbone" made of Modified Bricks 4733 with Rigid Hoses (cut to 4.5L) running through; the relatively new oval 1x3 plates whose open stud holes are used to attach them to the ends of the Rigid Hose pieces; and finally the inversion of stud orientation in the sides, using the old hinge plates. The result is surprisingly sturdy. submitted by /u/BrickTrainsPlanes [link] [comments]
