Peter Posted August 17, 2018 Author Report Share Posted August 17, 2018 A set of pulley wheels need brackets to hold them in place at the top of the towers. Used aluminium plate. The towers are not yet installed. Just checking to see how the wheels line up with the span cable anchoring points. Also, where I need to drill cable holes into the bridge. Checking how the bumper rollers are to the tower. Link to comment Share on other sites More sharing options...
Peter Posted August 19, 2018 Author Report Share Posted August 19, 2018 Built up the top of the tower and added its servicing gangway. Link to comment Share on other sites More sharing options...
Peter Posted August 20, 2018 Author Report Share Posted August 20, 2018 Due to the nature of my design, which includes wiring under the bridge, three items have to be installed at the same time. That is, the towers, road base, and traffic lights. Took me awhile to find a solution that won't split the wood when drilling it. Making the traffic lights. Building the road and footpath base. Drilled countless holes for railing posts. Routed the wiring to go under the table. Installed towers, road, and lights. 1 Link to comment Share on other sites More sharing options...

Peter Posted August 21, 2018 Author Report Share Posted August 21, 2018 Spent a few days adding the railings on both road and footpath. Used matchsticks and split bamboo skewers. Link to comment Share on other sites More sharing options...
Peter Posted August 22, 2018 Author Report Share Posted August 22, 2018 Turned display table on its side to harness the wiring, from the bridge, towards the centre where the control box (pulley system and electronics) will be attached. Link to comment Share on other sites More sharing options...

Mark Deliduka Posted August 28, 2018 Report Share Posted August 28, 2018 I finally went through this and I am speechless and overwhelmed. What a massive and magnificent undertaking. Simply phenomenal work being displayed here. I am looking forward to seeing more. 1 Link to comment Share on other sites More sharing options...
Peter Posted August 28, 2018 Author Report Share Posted August 28, 2018 Thank you Mark @Mark Deliduka for your kind words and encouragement. Much appreciated. __________________________________________ The next part was to paint the road surface (concrete), which is different to the highway (bitumen). Tried to use a splatter technique which did not work well for me. So then I the dry brush dabbing method. Finally used a fine brush to spot dark (gravel) and light (cement) colours. It took a while, but I think it paid off. Painting under the span frame was quite difficult. The edges across the road between span and bridge are protected with steel plate (painted silver). Masked the road for centre and fog lines. Added small yellow reflectos down the road centre. Later, I could not resist playing with the 1/74 (OO gauge) scale cars. 1 Link to comment Share on other sites More sharing options...

Peter Posted August 29, 2018 Author Report Share Posted August 29, 2018 (edited) Thanks Mark for your response. ________________________________ At this stage i needed a break from the bridge display. So I focussed on the console for a while. Renovating the interior and instrumentation. Edited August 29, 2018 by Peter 1 Link to comment Share on other sites More sharing options...

Peter Posted August 30, 2018 Author Report Share Posted August 30, 2018 Thank you Kev for for your wows. Much appreciated. ______________________________ To re-wire the console I had to create a wiring harness first. This is much larger than wiring a radio or a sterio internals. Done some reasearch into industrial wiring, such as for a car. They used a large peg-board to map out where the wires go. So I did the same thing. Then came the task of attaching the harness. Did not bother too much about how it would look under the control panel, nobody will see it anyway. But it was important to have no stress /tension on any of the wires. Installed the control panel with harness to the console. Initially used white plastic ties, but after connecting to the three terminal strips I replaced them with coloured ones. A smaller harness was made between terminal strips and the two D-Connectors at rear of console. These will bridge, via a multi-core cable, to the display control box.

Peter Posted August 31, 2018 Author Report Share Posted August 31, 2018 (edited) Added Passive InfraRed (PIR) unit inside console. This is to detect human activity near the console. Detected human movement will turn on interior lighting, to attract visitors to interact with the display. Added felt lining around front edge. Lined the interior edge with LED flexible strip. Added front Perspex panel, with kickboard cut from the original steel panel. Console diorama completed. Edited August 31, 2018 by Peter Link to comment Share on other sites More sharing options...
Mark Deliduka Posted September 1, 2018 Report Share Posted September 1, 2018 Brilliant move adding the passive infrared! I never would have thought of that. That console looks sensational. Man, I have to make plans to go see this in person someday! 1 Link to comment Share on other sites More sharing options...
Peter Posted September 2, 2018 Author Report Share Posted September 2, 2018 Thank you @Mark Deliduka for kind words. __________________________________________ Getting back to the bridge display, there was the matter of the land masses and riverbanks at each end of bridge. Starting on the North side with the footpath that goes under the bridge. Left (2010), right (2017). Took basic measurements and started modelling the stairs, etc. 1 Link to comment Share on other sites More sharing options...

Peter Posted September 6, 2018 Author Report Share Posted September 6, 2018 Thank you Peter @StrikeEagle, for your complimentive words. Glad you like the build log. ______________________________________ Now there was a matter of a partial house within the display boundaries. Assuming standard whole 'feet' measurements. I was able to get a good estimation of the house size. Decided to include interior lighting. Using an electronic ciruit which squences 5 outputs (LED lights). So, I divide the house into five rooms. Also added thin Perspex for windows. It was a bit tricky making the roof. Because the Masonite is 2.5 mm thick, I had to use wood putty to fill on the bevelled gaps. Included a painted figurine into the front enclosed verander. She is now overlooking the construction of the model Tested and created the sequencer circuit. Every 10 seconds one room light will turn off while an adjacent room switches on. This will appear as if someone is going from one room to the next. 1 Link to comment Share on other sites More sharing options...
Mark Deliduka Posted September 6, 2018 Report Share Posted September 6, 2018 Brilliant idea! Nice work on the lighting too. I can only imagine what it would be like for the owner of that house to see this display and recognize their home in this display. That would be so cool. 1 Link to comment Share on other sites More sharing options...

Peter Posted September 7, 2018 Author Report Share Posted September 7, 2018 Thank you Kev @Roktman. I do appreciate your responses. _________________________________________ The original bridge console operated swing gates instead of todays boom gates. Had lots of trouble finding an image of what they used to look like, until I saw this (enlarged detail). This gave me the go ahead to make the gates. They will be servo motor controlled. Used washers, brass tube, tin from a lid, fencing wire, flat wire, scrap plate, couplings fron electrical terminal strip, and fly screen. Link to comment Share on other sites More sharing options...
