Set-up with driver. Grip and clubface angle.

[Zeph]

What is the proper way to adress and set up with a driver?

Take the grip with the club in the middle of your stance then position the club at the ball?

Position the club at the ball, square up the clubface and then take the grip?

I'm currently hitting the ball left and right. It starts straight or somewhat straight, but after a while spin off to the right or left.

A vast majority of the pro's take their grip before taking their stance, then line up the clubface to the target while their chest is still facing the target(and step in with right foot first). Then they step in with their left foot, aligning their feet parallel to the target line, some of them re-grip before taking their swing, some don't.

After all this has been done they are ready to swing.

Same as with other clubs. Pick line from behind ball and choose a mark on the ground, inline. Put club in right hand and place it behind ball inline with ground mark. Step in with right foot. Finally, bring in left foot and make any fine adjustments. Hit ball.

Specifically for the driver, you want the ball position at your left instep. You want to be making a sweeping hit of the ball. I always aim to leave the tee still in the ground but that doesn't come off very often!

I do all that, but I place my left foot first to get the right ball position, then place my right foot.

One way to align.
Place clubface perpendicular to target line.
Stand feet together (touching), so that the line between your feet bisects the ball. (ball is at left instep(heel) for righty. Move right foot back to shoulder width (or whatever feels good)
Waggle.
Strike the ball.
