 ====== Laser Chimney ======
-===== TODO =====
+Our laser cutting is currently restricted to the hours of 8pm to 8am to avoid annoying the users of the Summerhall courtyard with smelly fumes.
-  * Confirm final size - go outside with a tape measure and see whether 315mm seems reasonable, including extra width for mounting brackets
-  * Pick out wall anchors. Need to check what size bolts the mounting brackets will take
-  * Pick out flexible ducting for fan -> window connection. DuctStore has some good stuff but 5m minimum. Probably go with the same stuff we got for the big laser?
-===== Shopping list =====
+We are in the process of installing a duct to take the fumes to roof level.
