Build stage 3 involved fixing the telescope stand to the hardened concrete base. High power drills were used to drill 6 holes directly into the concrete before the steel stand could be securely bolted in place. The piles used have to be sufficently long and strong enough to endure the 100+kg of telescope equipement on top of the stand. The stand itself is hollow, designed to be filled with kiln dried sand to add weight and strength to the whole strcuture. This will be supplied and included in the next build day.
