BA1b 3D - Time Machine 5

I've moved on from the drawing phase and have started modelling my bell. I created a sphere first, trying to figure out how I would make the indents in the shape. I concluded that I would have to add more divisions, and turn it so it was an easier cut. I then proceeded to cut the shapes out of the bell, deleting faces and moving vertices. 

The next step after I had made the bottom of the bell was to create the three parts that you turn, so I made a torus shape around the same size as the top of the bell I had made, and then deleted the insides of the shape as seen below.

I started to cut only the bottom faces of the torus, and then realised that this would mean I would have shapes with over 5 sides above the areas where I've cut.

I thus decided to use multi-cut through the shape where I needed more edges seen below.

And then welded them together with the target weld tool.
