By design, the modification doesn't take into account any adjustments you make using the micro-adjustment. In other words, the bullseye is 100% accurate only when the swivel arm is hard against the fixed part of the stop. Having said that, it doesn't mean that you can't use the micro-adjustment, you just need to plan ahead (which is commonly the case with micro-adjustments). {{:tools:woodshop:table_saw_stop_1.jpg?400|}} {{:tools:woodshop:table_saw_stop_2.jpg?400|}} ===== Accessories ===== ^ Image ^ Category ^ Accessory Name & Notes ^ Location ^ Buy from ^ | | Sled | **Mitre Fence for sliding table** \\ The mitre fence that fits the sliding table | Bottom drawer of accessories cabinet | | | {{:tools:woodshop:mitre_fence_for_main_table.jpg?100}} | Sled | **Mitre Fence for main table** \\ The mitre fence that fits the main table | Bottom drawer of accessories cabinet | | | | Material Handling | **Sheet Clamp** \\ This is used with sheet goods to clamp them against the sliding table fence, ie an extra set of hands | Bottom drawer of accessories cabinet | | | {{:tools:woodshop:featherboard.jpg?100}} | Material Handling | **Featherboards** \\ Extra hands to help you keep material constrained | Fourth drawer of accessories cabinet | | | {{:tools:woodshop:push_sticks.jpg?100}} | Safety | **Push Sticks** \\ Many types and sizes and shapes, use these to get distance from the blade | Top drawer of accessories cabinet | [[https://www.carbatec.com.au/push-stick-large|Carbatec]] | | {{:tools:woodshop:blade_change_spanners.jpg?100}} | Maintenance | **Blade Change Spanners** \\ 1 Arbour pin, 3 Spanners, for main blade, scribing blade, riving knife.
