-===== 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 anchorsNeed to check what size bolts the mounting brackets will take +We are in the process of installing a duct to take the fumes to roof level. 
-  * Pick out flexible ducting for fan -> window connectionDuctStore has some good stuff but 5m minimum. Probably go with the same stuff we got for the big laser?+ 
 +===== Status ===== 
 + 
 +The fan and ducting has been installed. 
 + 
 +To-do:
