Laser Chimney

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.

We are in the process of installing a duct to take the fumes to roof level.


  • Install the bracket that will support the blower. The bracket will be mounted on the outside wall, above the window between G1 and G2. This will probably require the borrowing of a larger ladder.
  • Install the blower on the bracket.

When the blower is in place, we can begin the following:

  • Order the vertical ducts and accessories to reach roof level (these will be too large to store so should be bought when we are ready to use them).
