## Facts

- Vacuum-table routers no longer ship **rubber cords** in the default package. Ship **silicon** instead (plus the matching table accessory).
- Fit **6 mm supawood** as spoilboard. Seal the board to the table with silicon. Boards can be joined with silicon. Zoning still uses the table switches.
- Goal: better vacuum hold-down than rubber cord.
