There has been some time between posts, but I am back and motivated. This year (2017) in August there will be another Branchline Forum at Coffs Harbour, and the theme for this Forum is "Building a Layout", covering;
How to Plan, Build and Scenic a NSW Layout, And I thought, what a perfect time to show a couple of the main modules for Peak Hill (yes I know it has only been 150 years in the making --- slight exaggeration, but the intent is there.) The modules I am talking about are modules 5 and 6 which are the ones with most of the point work, and the grain shed and bulk shed which are being redesigned and drawn to suit new materials and new methods such and 3D, laser cutting and more challenging etching methods, and results.
These points take up a tremendous amount of real estate, but they will look fantastic with all the point rodding and detail that will be included.
The frog etches arrived the other day and I realised that I had made a small error to all but the number 6 frogs, so a re-run is necessary and they should be available in a couple of weeks. Both for sale as well as for the layout.
There have also been some changes to the original concept of the curved backdrop as there were elements of that that were too difficult to resolve, so I am now going with a light weight module method using 4 mm ply and 90 mm pine sections with a foam base and the odd riser, supporting the road bed.
The following photos will give a good indication of the module construction that I have used.
|The module with all the panels in there locations ready for the screwing and gluing.|
|The panels with descriptions of the parts.|
|The external corner note that the screw holes are offset so as not to interfere with each other.|
|The internal corner joint. The screws go through the ply and into the centre of the pine, and are glued for extra strength.|
To strengthen the top of the corner joint, small sections of pine can be glued and screwed into position, 50 mm polystyrene foam is used to fill the modules with risers used to support the track bed through the foam. I am looking at using a spline method of track bed similar to Ian Millard's Liverpool Range layout. He uses 25 mm sections of Masonite sandwiched with ply to build up the track bed, a cork layer fits on top of the spline and sleepers and rail on top of the cork.
The modules are joined using 3 x 5/16" "T Nuts" with home made wing nutted bolts made from 5/16" Booker rod. There will be 2 x 12 mm alignment dowels, which I have sourced from Station Road Baseboards in the UK . These dowels are easy to use and are reasonably cheap compared to the Aluminium dowels available elsewhere. The module alignment will be done when the road bed and track are fitted.
Next I will have the 2 modules together with the form inserts, and be looking at the track plan and point design.
