    For those who enjoy making their own track here is a simple device I made today, its a rail chair spacing gauge for aligning the C&L bullhead chairs onto ply sleepers correctly. The gauge ensures both chairs are equally spaced and will set to gauge, just load the rail with a few chairs and position each one over a sleeper checking the sleeper butts up to the edge curb and then glue the chair down on the sleeper, once dry glue the other side and slide off. Normally there are 24 sleepers to every 60 foot length of rail so loading the gauge with eight sleepers at a time I can get a panel length of sleepers done every three passes, just need to make sure each chair with key faces the correct way to traffic and at joints.

    Hi Paul

    Many years ago, I made a jig for P4 track, I used 1mm card spacers of the correct width (allowing for the sleeper being closer at the rail joints) and rail joins marked on the jig. I only fixed one rail in place on the sleeper and laid the track, then using the track gauge laid the second rail. I remeber the track gauge being triangular in shape to give the correct gauge widening on curves. I staggered the actual rail join, but put a partial cut into the rail (only through to top of the rail). This gave a really authentick clickerty click sound.

    Good advice Paul, the plan is to chair up 1 metre lengths of flexi-track forming the curve through Leek station... with long rail lengths like that it would be best to chair one side only then feed sleepers onto the rail and then set the other side chairs to ease stress. I've calculated that I need 175 inches in length to carry the platform rails from the bridge to the top of the platform ramp... this will be the longest segment. More as this develops of the Leek Station thread.:thumbup:

    Thanks again for your helpful advice Paul. :cheers::tophat:

    cheers Yorkie
