This diamond toothed stone saw was designed and built by Seattle Solstice our partner on the stone cutting portion of the underground project. One of the main challenges we are facing with the underground development of the Clock space is how to cut the stair access along the vertical tunnel where much of the Clock mechanism will be. Stuart Kendall of Seattle Solstice designed this solution which puts a diamond belt saw on a triple articulated robot arm. The saw has a working envelope of 32 feet in diameter and uses a 9 foot diamond belt usually used in quarrying operations. Water is pumped through the whole system to suppress dust, act as a coolant, and act as the bearing surface for the belt.

The second half of the video shows how the saw would be used to cut stairs. This simulation was done by project engineer Brian Roe.

Hmm…it looks like things are taking a while to load. Try again?
