In the switch tables below the cells coloured yellow show where the soleplates are fitted; the cells coloured grey show where the switch anchors are located; the vertical black lines indicate the positions of the rail joins; the dimensions show the distances between the centres of adjacent chairs.

In the tables below only one half of the slip is shown; the other half is mirrored left to right at the central SN timber with those Left and Right chairs being mirrored top to bottom. The cells coloured yellow show where the soleplates are fitted; the cells coloured grey show where the switch anchors are located; the vertical black lines show the location of the rail joins; the dimensions show the distances between the ends of adjacent timbers (note that some are skewed hence the seperate dimensions for each end of the timber).

Chairs

You MUST clean the waxy manufacturing coating off before painting or glueing. If you've an ultra-sonic cleaner then give it at least two cleaning cycles, using fresh water each time. Otherwise hand-hot water with a very small amount of lanolin-free detergent (usually found in a box next to the washing machine!) and a brush. Then rinse with plain water and brush again. Keep changing the rinse water until all traces of the wax have disappeared.

Check for dimensional errors if the layers go this wayCheck Rail Chairs CC, CCL and CCR

Measure the sprue across hereInspect your check-rail chairs for possible dimensional errors before you go too far. I have had a couple of prints which have been up to 20% oversize in one direction. The main culprits are the smaller prints with the layers running as shown in the image left (the layers won't be this easy to spot!). Measure the sprue around the reference number as indicated by the blue arrows in the image right, which should be the same dimension as the flangeway (1.75mm in this example). If you have any problems then please contact Shapeways' Customer Service for a reprint of your order.

The running rail is correctly inclined at 1:20 but the check-rail is, like the prototype, verTical and this is indicated by a T underneath. You may wish to further highlight the check-rail jaws (especially the end ones) with a felt-tipped pen before removing from the sprue with a sharp knife.

Thread the chairs onto the previously prepared check-rail (see Check Rails for details) and then slide the running rail through the other jaws. Check the height of the rail against adjacent chairs and adjust if necessary by rubbing the base of the chairs on some fine abrasive paper.

Use check-rail-gauges to position the check-rail the correct distance from the opposite running rail and then glue the check-rail-chairs to the timbers. Use either a cyano-acrylate "superglue" or, for less instant bonding, then something like Uhu, Bostick, epoxy resin or an impact adhesive used in non-impact mode may be suitable.
