I know that in a perfect world we just buy boards without bad knots or buy enough to be able to work around them. For some of us, that’s not always possible.
Anyway, I’m building a bench top by laminating hand-planed boards face to face. I’ve come across a couple of knots that are really tough and were making planing a real pain. The average size of the knots is about the size of a couple of quarters side by side.
Since the knots are on the face that will be part of the glue joint and not visible, I marked out a rectangle using a marking knife and square. Then, I used a mortising chisel to cut out a mortise where I had marked the rectangle. Next, I cut a piece of the same species to fit snugly into the mortise and clamped / glued it into place to fill the void where the knot was; making sure the grain was running the same direction as the board I’m inserting it into. Once the glue is dry, I plane it level with the rest of the board and proceed to plane the entire board flat so that it can be glued up with the rest of the top.
The “repair” is on a part of the board that won’t ever be seen. I was wondering about wood movement issues, but since the species is the same and the grain is running the same way, I’d think that the “repair” piece would shrink and swell along with the board it’s being added to.
I’m just curious if this is something that would be considered okay. Are there other things I should be worried about? Or am I just over-thinking something simple?
