Cut the cork or rubber underlay, chamfer to 45 degrees and glue to the baseboard if required. Spread on even layer of glue (Fuller's Max Bond or PVA will do) over the Track Template, this glue layer needs to be fairly thick (not too thick though) or you will not be able to see the sleeper positions on the template. Only put glue on as much of the template as you can reasonably place sleepers on before the glue starts drying.
Lay the sleepers, aligning the centre line on the template and the centre mark moulding on the sleepers. When you are satisfied with the result pour ballast over the lot, press ballast firmly down and brush off the surplus with a soft brush, do not wait the usual 24 hours, by doing this the glue will dry faster. Alternatively if you are using thick timbering, the ballast can be done after the track is built.
The chair mouldings have wooden keys moulded in different hands, on the prototype these keys were pushed or hammered into the chair in the direction of the main running of the line, so that as the rail crept along the key would become tighter. Choose the correct hand of chair and thread the correct number onto the length of rail. Make sure that the rail end is square, file to remove burrs, then put a slight angle on the base and lower sides as well as the web. Also ensure that the rail Is the correct way up, the larger section of the bullhead should be uppermost.
Using a pointed instrument or scriber, space chairs at the correct distance apart using the sleepers as a guide. Glue the first rail down and when the chairs are firmly fixed, after a couple of minutes, lay the second rail to gauge in the same way. Make sure that you use the correct hand of chair for the second rail (it will be the opposite one to the first rail you glued down).
