How do you attach the truss rod ends to<br />
the frame? On the prototype, the rods<br />
continue between the bolsters and deck,<br />
passing through the end beams where they<br />
are tensioned, using truss washers and<br />
nuts. I have used several methods of<br />
anchoring the ends of the rods, in<br />
modelling, taking them through to the<br />
beams is difficult and the results are<br />
somewhat disappointing. I have also bent<br />
the ends of the rods at right angles and<br />
inserted them into predrilled holes in the<br />
centre sills, but this requires very accurate<br />
measuring and bending to get it right. The<br />
easiest and most effective method is to<br />
simply just dribble some 5-min. epoxy or<br />
hot glue directly onto the truss rod ends,<br />
which in turn bonds the rod to the frame.<br />
Once the underside of the car has been<br />
painted, these lumps of glue are hardly<br />
noticeable and will be totally invisible<br />
when the car is in operation on the track.<br />
While waiting for the truss rods to cure in<br />
place, now would be a good time to cut<br />
the mounting block for the Accucraft<br />
couplers from 10mm ply and glue in place<br />
(see drawing sheet 2). If you plan to use<br />
another type of coupler, leave out this<br />
step. Coupler installation will be covered<br />
in chapter 3.
