  2. Model railroad layout - Wikipedia

    en.wikipedia.org/wiki/Model_railroad_layout

    Micro 'pizza layout' with 9 mm gauge track in 7 mm scale (09 scale) An important aspect of any model railway is the layout of the track itself. Apart from the stations, there are four basic ways of arranging the track, and innumerable variations: Continuous loop. A circle or oval, with trains going round and round. Used in train sets. Point to ...

    High rails on a model railway layout at the Convention of American Railroadfans in Switzerland, 2006. High rail (also called "hi-rail" and "hirail") is a phrase used in model railroading in North America, mostly in O scale and S scale, to describe a "compromise" form of modelling that strives for realism while accepting the compromises in scale associated with toy train equipment.

  4. Model Railroader - Wikipedia

    en.wikipedia.org/wiki/Model_Railroader

    A longstanding philosophy of modeling is manifest in its editorial features of layout design and operation, in which the model is viewed as a three-dimensional and temporal compression of the real world, so that, for example, the motive power, freight, trackage and scenery of a real-world railroad are formed into a layout which captures the ...

    A scriber is a hand tool used in metal work to mark lines on workpieces, prior to machining. The process of using a scriber is called scribing and is just part of the process of marking out . It is used instead of pencils or ink lines, because the latter are hard to see, easily erased, and imprecise due to their wide mark; scribe lines are thin ...

  7. Marking out - Wikipedia

    en.wikipedia.org/wiki/Marking_out

    Marking out or layout means the process of transferring a design or pattern to a workpiece, as the first step in the manufacturing process. [1] It is performed in many industries or hobbies although in the repetition industries the machine's initial setup is designed to remove the need to mark out every individual piece.

  8. Surface imperfections (optics) - Wikipedia

    en.wikipedia.org/wiki/Surface_imperfections_(optics)

    These imperfections are part of the surface and cannot be removed by cleaning. Surface quality is characterized either by the American military standard notation (eg "60-40") or by specifying RMS (root mean square) roughness (eg "0.3 nm RMS"). [1] American notation focuses on how visible surface defects are, and is a "cosmetic" specification.
