Chasm Monastery - Room with Huge, Hanging Bell - Part 2

There's a huge bell hanging from the ceiling and a rope-wrapped clapper which was probably once used to ring the bell. There are also 2 cranks that still work to open the shutters at the corners of the room. Notice, too, the cracked sections in the beams supporting the ceiling and therefore the bell.

Start by cranking open one set of shutters. It doesn't matter which one you do first, but I recommend starting with the shutters on the right when facing the two sets with your back to the bell, since this will put you in a slightly safer position for the next combat.

The wind blows furiously, swinging the bell clapper wildly. It needs a little help to move in the right direction.

Turn away from the crank so the open shutters are behind Lara. Shoot a rope arrow into the clapper.

Lara yanks on the rope, but the wind does the work...

...smashing the clapper into the beam and destroying it. One down; two to go.

Use the same crank again to close the shutters you just opened.

Then move across the room to the other crank.

Use it open that set of shutters.

Again, turn around and shoot a rope arrow into the clapper and pull.

The clapper then smashes the other vertical support beam.
