How much does a drill bit cost? And a sixpack of your favourite drink? How much do you want to suffer from lack of drills with hundreds of holes to go? Buy a stack of the drills, and go for the 45 minute lifetime. High speed, enough coolant/cutting fluid, ease up on the feed if you want to take thin...

A BBQ with regular charcoal should do fine. Heat until the rings are red hot. If you're doing this outside in sunshine, you won't be able to see the colour. When at red heat, just let them cool by themselves. There's not much you can do wrong here. If the rings won't get red hot, cover the whole thi...

This type of articulation became popular when armour was losing its prime purpose of providing protection in battle.
