Fitting extractor fan to Selsey

This is the very large drill bit I used to remove some of the brick,

but most of the holes are 10mm. I drilled all the way around the circle and then using a chisel and hammer, I removed the plaster and brick.

If I do this again I will make the hole slightly smaller, I left too much clearance. Once I broke through the inside bricks I was able to drill a hole though the outside layer of bricks so I could work out where to start drilling from the outside. You can see the sunlight in the small hole in the centre.

This is on the outside wall, same story all over again.... Have a look at the pile of brick dust resting on the top of the ladder in the bottom of this photo.

Finally finished!
