I built this model so that you can use a battery driven circular saw as a table saw. It's a trigger so that you can reach it from the front of your table as an emergency stop - which you dont have in battery tools. You just need to add an M5 threaded rod to the lever and attach a button to push it to your workbench. It is built for the Makita DHS680.

You could also make a foot lever.

For this model you need (links at the bottom):

8x M4 50mm
8x M4 nuts
2x M5 nuts
1x M5 threaded rod
