Three hours and a power saw gives you a book rack. Too bad our power screwdriver wasn't working, or this would be finished by now.

PS: I designed this rack for our office, and built it with the help of two guys from the office. It cost us less than ₹5,000 in material and power saw rental, and three hours of our time. The cheapest quote we had was for ₹24,000 😯. After a month of haggling with carpenters, we decided to just build our own.
