Resawing

To resaw is to recut a board usually into two thinner boards.

Resawing results in 2 thinner boards and reduces waste from planing down a thicker board.

Here are some suggestions for successful resawing:
  1. Use a higher fence than the usual fence that is clamped to the table (you may need to make this up)
  2. Push slowly and evenly (don't rush it!) Rushing forces the blade to deflect and buckle.
  3. Make sure your bandsaw is totally tuned up (sharp blade, level table that is secure, friction blocks touching the blade, proper blade tension)
  4. Joint the lower edge of the board you want to resaw so as to keep it flat and even on the table.
  5. Scribe a line on ALL sides so you can check your work for an even cut.
  6. Use a bandsaw blade with very few teeth per inch (say 2-4, versus 10-12) (This requires less power and allows the sawdust to leave the cut)
  7. Use as wide a blade as possible (1" versus 1/2" - This helps prevent blade buckle).
  8. Aim for your line, adjust as you cut and "pull" the board through at the end of cut to avoid cutting your fingers :)

Resawing is a very useful technique for carpenters and cabinetmakers. Our first project will require you to master it.
