Mayner Posted November 17, 2012 Share Posted November 17, 2012 I knocked up a couple of sample panels of track to try out different techniques for the new layout whenever I get round to starting it. The layout will probably be based on the Burma Road in the 1950s & 60s secondary main lines have a certain appeal with fairly compact stations and laid back operation. The line was basically a Southern incursion into Midland territory in steam days operation was centred on Limerick and Tuam mainly worked by J15s and small ex-GSWR 4-4-0s Track was mainly jointed flatbottom but some sections were laid in bullhead I wanted to capture this mixture plus the distinctive centre-cess drainage once common in many parts of Ireland. Two samples were made up one in Bullhead using C&L plastic chairs and sleepers the other using flatbottom rail and copper clad sleepers. I decided to try the American style split track underlay which simplifies setting out, simply line up the edge of the underlay with the track centre line than fix the other piece. Cork and rubber versions are available locally. The second side bevelled to represent the centre cess. Underlay glued in place using a French PVA that is reputed tobe good at sticking anything to anything 10 minutes later ballasted section of centre cessed track, the cess acted as a drain so might need a touch of varnish or Ez-Water. The sleepers are a deeper section than standard for handlaid track used to represent unballasted track and situations like this. Flatbottom laid in pva awaiting ballast. Voila ballast sprinkled in place, surplus removed and not quite 3 year old ganger inspecting bullhead panel in background. I am not sure how this will work out in practice, the chaired bullhead is generally assembled by fixing the sleepers in place on a printed template, threading the chairs onto the rails, gluing down one rail the gauging and gluing the second rail in place. Copperclad is usually laid by soldering one rail down to the sleepers in a jig then transferring the half track to the baseboard, then gauging and soldering the second rail in position. The chaired track involves a lot more work threading the chairs onto the rails then gluing everything in place, the whole assembly tends to be quite fragile until assembly is complete. Anyway it should be interesting if I can keep my sanity threading on my current stock of 500 chairs enough for roughly 2 metres of plain track Quote Link to comment Share on other sites More sharing options...
