Steady lubrication for big cutting jobs
IF YOU’RE DOING cutting that needs constant lubrication, like using a saw to cut through concrete, a 20 litre paint bucket is a handy tool. Jab a hole in it near the bottom with a screwdriver, and fill it with water. If someone holds it above the cut, water will leak out at just the right rate to keep the saw blade wet.
