Tracy Tools have the taps.

eBay ...  around £4 for a tap. Because it's brass you don't need anything to expensive. The 7.3mm drills are about the same cost.

You can use a hand/battery drill although a bench drill would be better. I drill a hole the same size the case body in a piece of softwood which I then cut in half and clamp in a vice, holding the case solid is key.
