When I've done my brake pipes I've tried to avoid putting unnecessary joints in. I've just run a whole length of pipe. That way there is less to go wrong. I've tried the cheap tools such as you get from Machine Mart and they're OK but my favourite is one like in post 5. Makes the most beautiful little pips that look like they came from the factory.
