Visited my parents and faffed around for close to two hours, trying to remount a 5-6m pine handrail back onto the wall along their steep stairs, using the oldest and naffest set of tools.
Drilled new holes in the rail and the wall. Tried to use frame fixings, failed, got dispirited, rummaged in the garage and started again with bog standard rawl plugs. The cheap corded power drill made some smoke when driving in the screws, fragrantly reminiscent of overheating Scalextric cars.
Rail finally secured on the wall and parents happy. Reward was curry and ice cream.
