Vacuum CNC router: silicon + 6 mm supawood, not rubber cord Source-Date (SAST): 2023-10-12 16:28 Dest: both Review-after: 2027-02-28 Status: current 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.
