... . 2_311418_400000001.png Creating that divides into several stages: 1. the easy bit. Create the basic alignments by overlaying normal templates: 2_311417_540000000.png 2. the straightforward bit. Create diamond-crossings at the intersections: 2_311501_480000000.png 3. the tedious bit. Separate out each K-crossing and V-crossing as a partial template: 2_311417_540000001.png There are 2 diamond-crossings, so that means 4 half-diamond templates, each having 2 K-crossings and 1 V-crossing, so that makes a total of 12 partial templates: 2_311417_540000002.png 4. the creative bit. Extend them to link together, ensure all crossings are checked, and modify the check rail ends to clear: 2_311417_540000003.png 2_311417_540000004.png 5. the conundrum bit. Shove the timbers to support all the crossings in the correct place: 2_311418_390000000.png I will be splitting up each stage as a separate video in the interests of sanity. Watch this space. 6. the difficult bit. Design the chairing based on the known chairing practice of the required prototype. Over to you for that. 7. the ...
