When a knot is missing, try a heat gun
I am working on a step-back cupboard based on Mike Dunbar’s great article from FWW #165 (October 2003). I like to leave natural imperfections in the wood, but in this case a knot was missing entirely. To create a darkened plug that looked like the missing knot, I used my heat gun on a shaped piece of scrap from the same wood. I’ve tried burning the plug in the past, but that obliterated the grain. The heat gun works wonderfully, letting me toast the wood to the color of the knot hole while letting the grain show through. To hold the plug in place, I used a cyanoacrylate glue designed for wood.
