The installation of the truss rods is the most difficult part of building this flatcar. For this project I use<br />
relatively cheap 1.5mm welding rod, available from welding supply shops. Brass rod (0.0<strong>6”</strong>) can also be<br />
used. Two 2’-0” length’s or 1250mm will be required. Cut 4 rods 285mm (11.22”) to length. To bend the<br />
rods, measure 100mm (3.94”) in from each end and mark. Place the rod across 2 of the queen posts, the<br />
marks on the rod should be over the centres of the posts. Now remove the rod and using a pair of pliers,<br />
gently bend the rod down, using the marks as a guide to the bending point. Test fit the rod across the<br />
queen posts. The ends should just touch the underside of decking without lifting off the queen posts. Keep<br />
adjusting the rod till all 4 contact points are making contact with the car, as pictured. Bend the other 3<br />
remaining rods to shape. Note: the 2 inner truss rods may have to be trimmed to allow for the thickness of<br />
the lead weight, if installed. With all the rods bent to shape, place a small amount of 5 min. epoxy in the “u”<br />
shaped part of the queen post brackets and drop the newly formed truss rods into place. Make sure that<br />
the ends of the rods are hard up against the centre sill beams.
