Basic orientation: transpose needle from ADF to DI and get tracks to and from the station.
For all intercepts: first ask "do I have a solution?" i.e. will the head fall or tail rise onto the required track?
Inbound: set up a heading so that the *head will fall* onto the required track. Turn to a heading past the current track to the station to set up an intercept. (i.e. turn from current heading, to current track inbound, and through to an intercept. From it, to it, through it)
Outbound: Easier (a little...) because you don't have to make the intercept by the station. Turn so the needle will rise to the required track, if it isn't already set up to do so.
I've found (in limited experience I will concede) that keeping it simple then developing familiarity works better than trying to get a complex method (i.e. mathematical) to work - flying then deteriorates and makes the whole job much harder.
