This is mostly old news to many of you, but I had an hour to spare and thought “why not”.
I’m installing some room pass-through jambs made of Poplar. My wood stash had plenty to select from but I picked a piece that had the length to get most of my parts out of.
Measure, cut, then realize I didn’t have enough length to avoid a large knot at the end of one side. These parts are going to be painted, but Ive seen plenty of long term issues with trying to putty/spackle knot holes.
This seemed like an opportune time to try an old trick and patch the knot for good.
Step 1, figure the patch area (about 4”x3”). Not brain science or rocket surgery, just big enough to be stable. I surrounded the marked out area with double sided tape.
Step 2, lay down some Masonite to form a template. This arrangement with straight edges makes for a perfect rectangle, which makes cutting a patch simple.
This is so I can use a hinge mortise bit to follow the template edges and get a clean cut. The bit is a Whiteside, 1/4” shank, 1/2” cutter with bearing.
This is one of my favorite tools, the Bosch “Colt” laminate router. Handy size and comes with a load of accessory gizmos to do about anything. Low cost to boot.
Step 3, zip, zip, the recess (about 3/16” deep) is clear in one pass.
A patch was made from my scrap collection. No need to worry about matching anything up since it will all be painted over. Doing this with the intent to have it perfectly blend in and disappear on natural (not painted) wood is very difficult. Most people will make the patch odd shaped (to accent it) or not patch at all and maybe inlay a stone or something attractive.
You can square up the corners of the recess or just round over the edges of the patch.
Step 4, the glue.
Smack it in with an “adjustment tool”,
then clamp for about 30 minutes.
Knot is gone!
A few passes with the sander and I’m back in business.
Have a great weekend everyone!
