interesting notes on sawstop that I found today:
https://www.sawstop.com/support/report-a-save/ says “If you send us your activated cartridge, along with this completed questionnaire, and we determine through our diagnostic processes that contact with skin triggered the activation, we’ll send you a new cartridge free of charge.”
Also, the following items have been found to trigger sawstop by users when they touch the spinning blade:
- UHMW plastic, due to static electricity buildup.
- carbon-fibre laminations ( on timber ).
- wet wood.
- aluminuim (or any metal really).
- embedded nails in timber.
- rulers/squares/fences/rails/jigs that are conductive ( like steel rulers, aluminium rails)
- g-clamps and other metal clamps
- pressure-treated lumber
- wet glue ( pva wood glue is water based )
…and it appears that most shops report it firing between 2 and 6 times since they bought their saw. one person had it fire 2 times in the first 2 months, one has gone years without a firing, but they cut only new wood and only have 1 or 2 operators who are both highly-aware of the firing risks, so the most likely scenario is that it will fire multiple ( maybe 5-10) times in the time we own it ( presumably 5 years or more ) .
