Bridge - parapet walls, facing stonework.
Tunnel - retaining wall timbers, facing stonework.
Platform edging.
A two-pronged attack on the bridge:-
When fitting the road surface, the natural contours of the block supports was followed, to take advantage of the undulations. However, we agreed that the parapet height, should be constant off the road surface, so Geoff produced small sections of card and MDF to the agreed height and glued them in place. As well as fixing the height, the additions will increase the core-thickness of the wall to give an overall, finished thickness of just over 18", once the plastic stonework is applied.
We also decided that the coping will be a bull-nose section, flush with the faces of the wall (i.e. no overhang). A suitable section will be sought/manufactured - probably in timber, or MDF.
Stephen applied himself to the stone face sheets and was pleasantly surprised to find that the pattern repeated itself. After some judicious cutting-out, a backing strip of plasticard allowed two sheets to be joined and cut to shape. Discussions took place on the design of the arch edging stones. A Google image search provided excellent prototypes and a clean stone edge with wall stones trimmed to suit was agreed. (Watch for developments).
The tunnel mouth stone sheet was cut to shape. However, the narrow piers either side of the opening didn't lend themselves to the same treatment, but a similar arch sitting on plain stone jambs was a perfect alternative.
Laurence took another batch of 'sleepers' and progressed the tunnel mouth retaining wall. Before he started, Geoff got the belt sander out and flushed-up the montage of timber base-work. An interesting effect was achieved, soon to be covered up.
Laurence also returned to the platform (not before time!) and glued the edging stones into place. We were all surprised how it brought the platform to life.
The centre will have a skim of filler applied and (possibly) a sand finish.
