KAG - Eridge rebuilding gets under way

Some progress over the weekend at KAG on rebuilding the group layout Eridge after problems with baseboard sagging on Mk1.

Templot plan cut to give 1.5" margin from the sleeper ends and used as a template for cutting the trackbed surfaces from 6mm Russian birch ply. The two further boards have already been cut (each 8ft long) - Mike is marking out the third. Simon keeps his wine rack in the garage hence the handy use of bottles as weights to hold the track plan down!

First two boards with transverse ribs in place (8" deep).

First board with side frames glued, pinned and clamped in place. This is the only one where the sides themselves are curved - the others will have rectilinear boxes (and triangles on the wider bits) with longitudinal strengtheners as well, so there will be some bits where the trackbed overhangs the box-frame sides slightly (not sure what the bottles were being used for at this stage!).

The trackbed boards will sit on wider trestles or goalpost-type supports at 4ft intervals (but with the board joins mid-way between supports to avoid any tendency to sag from that point). Scenic add-ons will plug in from the sides, probably built on super-lightweight carcasses made from foam board shaped to fit.
