- This machine is for removing planer chatter marks, or creating a semi-smooth surface on solid wood. If more than 1/32” of wood needs to come off, use the thickness planer.
- If you have any questions; check with a Board Member, or Shop Manager.
- Minimum Board Length:
- 8 inch minimum length (with or without sled).
- 2 foot maximum length.
- Board thickness:
- 1/8 inch minimum thickness.
- ii. 3 ¾ inch maximum thickness.
- If you glued the wood today wait at least 24 hours before running it through the sander to prevent glue from damaging the sandpaper.
- When sanding multiple boards, they must be the same thickness!! You cannot surface sand boards of different thickness at the same time!!
- Things not to be done:
- Don’t sand wood with any excess exposed glue (scrape it off first).
- No sanding of pine boards.
- No sanding of painted or boards with any finish on it (use hand sanders).
- No sanding of MDF, particle board, plywood, or Melamine.
- Don’t turn crank more than 1/8 of a turn.
- Remove any loose knots in the board before sanding.
- Surface Sander # 74 has one sanding drum.
- Make sure sanding drum and conveyor belt switches are turned off.
- Open top hood of sander and inspect sand belt for any tears or burn marks. Make note of any damage and report it to the Shop Manager.
- Measure thickness of board and then check it against machine thickness indicator for preliminary pass. Make machine indicator mark slightly thicker than board itself.
- Turn on conveyer belt and run the board through with sanding drum not running.
- Slowly raise conveyor bed until the board just barely causes the sanding drum to rotate. This is the most critical adjustment in setting up the machine!!!
- Start up sanding drum and run board through while slowly cranking conveyor belt up till it starts to touch the board.
- Close the top hood.
- Start up the sanding drum.
- Run the board through 3 times. This will give a more uniform sanding and help prevent damage to the sand paper.
- Turn crank clockwise 1/16 of a turn. Turning it more than 1/16 of a turn can damage the sanding belt. Remember, you are only taking off hundredths of an inch.
- Run the board through 3 times before raising the conveyor belt again.
- When sanding oily exotic woods or fine grain woods (purple heart, teak, paduak etc…), sand very lightly with each pass (less than one indicator mark) and use a fast conveyor belt speed to prevent burning of the sand paper.
- When finished: turn off all switches, clean up your mess (sweep floor, brush off conveyor belt) and close vacuum vent.
