A suggestion of how to connect the extension to the railer permanently (contributed by Peter Lineham with our thanks)

 


Glue a piece of MDF, retrieved from the spare parts of the fret, as shown in the first two pictures.  These pictures show the arrangement from underneath.  This piece of MDF should be about 20mm long and should be glued to cover the locator (for the tongue on the end of the extension), and extending about 8mm beyond the end of the railer.  Ensure no glue seeps into the locator slot. 

When the glue is set, make sure the tongue on the railer will still slide in to the locator – a little ‘jiggling’ may be required.  Hold the railer and extension firmly together and drill a 2 mm hole through the glued piece of MDF and the support piece of the railer a few mm beyond the tongue.  The hole created will be a tight fit for a piece of 2mm brass rod, or wagon axle.  Push a length of the 2mm rod (or axle) through the holes, so the railer and extension are held firmly together in place – some small easing of the holes may be necessary using a rat-tailed file.  Once the rod is in place, cut it to a length which leaves it just ‘proud’ of the glued MDF piece.  This is best done by removing the rod and, once cut to length, chamfer both tends of the cut piece of rod, to permit easier insertion of the rod in to the holes.  Replace the rod into the hole in the support piece of the railer - it should be a firm fit – and then test the arrangement by sliding the railer and extension together, so that the tongue drops in to the locator slot and the hole in the glued piece of MDF slips over the protruding brass rod.  Some easing of the hole in the glued piece of MDF may be needed and some ‘jiggling’ may be required.  If all fits firmly together, disconnect the railer and extension (some ‘jiggling’ may be required) and apply a little glue to the rod, above the support piece of the railer, between the top deck and the support piece, to make sure it stays in place.

Assembly and dismantling are best undertaken, with the sections to be connected upside down.  Once connected, the sections stay together well, and fairly firmly, and the whole unit can be moved about easily, without falling apart.  Disconnection is also quite easy, with a little ‘jiggling’.

The third picture shows the arrangements, viewed end on.  The fourth picture shows connected sections, from below and the fifth picture the connected sections from above.

Further extensions can be connected in the same way, but it is advisable to number them, as the holes in the different connections are not likely to be in exactly the same place!!
