Cut out depression in hill surface over entrance
Fit the surface sheet over the fiddle yard board
Fit cassette base unit on mine line
Laurence was given the job of cutting out the dip in the hill, directly over the entrance.
When Stephen's firm folded a few years previous, he took delivery of a large bundle of polystyrene site boards. A 4' x 2' sheet was trimmed to size and cleaned ready for gluing.
Stephen had an aerosol can of spray glue - unused - which sounded ideal. It was, but the spray patten and spread were quite amazing - a large spiders-web of glue drifted from the nozzle. We were so pleased we had decided to do the spraying in the garden! Quite a lot of cleaning with white spirit was required - top sheet, baseboard, compost bin, trousers, shirt, but the sheet went down onto the ply surface perfectly.
The mine line cassette base unit was fitted. The same tightness occurred as the main line, and a lot of easing/packing was required to get a decent fit.
The new top sheet was shaped to allow the wires to be secreted nicely. Once another full-length cassette has be made, a full running session can take place!
As well as cutting the dip out, Laurence started to make a timber frame over the hidden mine line, which will form the tunnel through to the fiddleyard and provide a base to build a higher hill in the corner.
Note the hole over the entrance. The resin was almost 10mm thick at some points - a typical John job.
To do:
Complete the tunnel and form the hill.
Make the cattle bridge. Note: the steepness of the hill probably lends itself to sheep rather than cattle.
Fit alignment pins in the board junction, as the other boards.
Make another cassette.
