Repairing Small Cracks and Checks with CA Glue

You’ve selected a beautiful piece of wood and at the beginning of the turning process, or part way through it, the wood begins to show small checks. Don’t throw it out! Those checks can be easily filled and will barely be noticeable in the end product.

  • With the lathe off, use a paper towel to dab the check with a small amount of the oil that you will use for your final finish—Waterlox, tung oil, mineral oil or other oil finish.  
  • Wipe away the excess.
  • Apply a small amount of thin cyanoacrylate (CA) glue to the check.
  • Use 220 grit sandpaper and sand the area, creating a slurry to fill in the crack.
  • It may be necessary to repeat the process two or three times before the small check is completely filled.
  • You are now ready to sand the entire piece and apply the oil finish you used earlier.

Applying a dab of the oil finish to the checked area before applying CA glue keeps the glue from staining the wood.
