  1. Hi, Thanks for your continuing interest I have ongoing problems with arthritis in both of the third and fourth fingers of both hands. Although I do get some occasional respite, any prolonged time modelling causes almost a shutdown. Any progress on the build in progress is exceptionally slow. However I haven't stopped and intend to now post when I can show some real progress, rather than a blow by blow account I have had to give up driving my Ford Mustang as although my reaction times are still good, I have no confidence in my ability to retain a good grip on
  2. Last night's pictures - The build starts with the interlaced cross beams, which is the reverse of previous builds where the interlacing was done last The lower of three cross beams is the normal/standard beam. Made from two 20thou machine cut styrene, placed and fixed back to back, with top and bottom flanges of 10 thou x 2mm wide strips. The beam's dimensions are 7.5mm high x 110mm long with 12 equally spaced cross braces The middle cross beam is a part modified beam which will allow the standard beams to interlace. The beam's dime
  3. Thanks Mike It is never too late, even after 15 years of modelling this project. The real aim is to try and capture some of the atmosphere and continual decay of these structures Ron
  4. A friend has managed to get some close-up pictures of the bracing and cross-bracing details, which have been elusive for quite a few years as access to the viaducts is not normally possible. However, with some telephoto equipment and a lot of patience, success has been achieved What all this means that the previous guessing game can be replaced by a more accurate representation of the real structural build, and should ease the overall model design and build process The second span which is under construction has been modified with three new types of bracing, replacing t
  5. The span is complete, and awaits painting This is the first of six spans which will extend the existing viaduct model into the garden A reminder of the existing viaduct model - The short angled span will be removed and replaced by the new span A few piers and castellated towers will be needed to make all the necessary span joints The second span is under construction
  6. Finally finished the second span beam. Modelling during the week is nigh impossible The second span beam is to the front A view of the central portion of the span beam showing the detail of the crossing of the cross bracing beams The overhead tie beams linking the two span beams are next to be constructed
  7. Hi, Mike Certainly has a higher UV resistance, but the cost is rather prohibitive, and would require a complete change in construction methods Ron
  8. Pictures held over from last night - Bit of a dash in construction to complete before the truss machine cutting was finished The angled end for the attachment to the third span deck A closer look at the deck structure The first 28 of 80 truss cut pieces. 72 required for the second span beam Looking for more progress this weekend
  9. The bridge model is still on display in the railway room and regularly receives a few 'oow aahs' from visitors The route of the railway tracks out of the railway room over the length of the viaduct spans and bridges is always in shade. Under non-operationing conditions and during those times the trackwork, viaducts and bridges will be completely covered by a removable weatherproof & insulated structure. With summer coming up rapidly (24-26 deg C today) now will be the time to carry out temperature checks prior to placing the viaducts and bridges in position. The real death deal
  10. Thanks Phil. I'm as healthy as can be expected, although I do suffer a little from Osteoarthritis in both hands (nobbly and painful finger joints). This is not causing me any problems modelling, other than slightly shorter working hours Ron
  11. More work done to try to get up to speed again - That's the work on the deck finished for now On to the first of the two span beams - Cut ? one of two 220mm x 330mm sheets of the truss pieces. Each sheet contains 80 pieces which will make up into 40 trusses. The Cameo cutter will not cut through 20 thou plasticard, so the Stanley knife will sort out this little problem - The lower item is two truss pieces fixed together to create the cross bracing of the truss. The upper item is th
  12. Pictures of the start of the first viaduct span build for the final four spans - A view of the underside of the viaduct span deck with 27 deck beams The first 19 beams are fixed on the deck with flanges of the 6 longitudinal beams used as spacers fixed to deck . The next 4 beams along the longitudinal beams await fixing to the deck, and the last 4 beams remain to be threaded onto the longitudinal beam extensions The overall dimensions of the deck are - 770mm long x 146mm wide x 18.25mm deep View of the far end of the de
  13. Have inspected the outdoor 'trench' in which the viaducts will pass through on leaving the basement, and after a little thought decided that the length of the viaduct will be extended to almost 3 metres (2.995m to be exact) beyond the exit point. This will make the transition from the viaduct to the concrete track base supporting structure easier to make The curvature of the trackwork will need four viaduct spans all of differing lengths - 770mm, 765mm, 815mm and 645mm. Unfortunately none of these match the length of brass etched viaduct span, and the modifications needed would be
  14. I was considering that to get some trains working sometime this year that the outdoor sections of trackwork could be more easily put in place. This would mean completing the viaducts both indoors and outdoors Have also decided that the remaining sections of the viaducts, approx. 1200mm in length will be built in styrene. The cost of brass etchings would be over £1200, against a cost of approx. £40 for styrene. To combat the problem of UV and heat degradation, and lizards, snakes and cats, the whole length of the outdoor section of the viaduct (circa 2 metres) will be protected by l
