… The materials can be purchased from any good hardware shop or DIY multiple store. The tools needed are relatively straight-forward; a small hacksaw or hobby-saw, a drill & appropriate bits, impact adhesive, suitable paint (if required), a fibre-glass kit (the sort you can buy in Halfords or similar store), sharp (e.g. 'Stanley') knife, emery cloth (or similar - to clean off sharp edges). Note that the adhesive method of joining some of the components has, with experience, been found to be a weakness: by all means use an impact adhesive to locate the items, but re-inforce with a fibre-glass bond.
