Before doing any work on the oil drum, it is definitely worth checking what is inside! Be very careful if there have been any flammable liquids inside as these could ignite when grinding! If you are unsure I would advise checking with someone! Any remaining liquids need disposing of accordingly.

For this stage you will need the paint removing disk for the angle grinder. You can also use a wire brush attachment for a drill but I found that the angle grinder removes it quicker!

It is a good idea to wear a dust mask / spray painting mask for this stage as it gets quite dusty! Place the oil drum in a stable location and begin removing the paint. It is worth spending the extra time making sure that all the paint is removed otherwise this will start to bubble when heated up, ruining the final paint finish!
