    Hello Stuart,

    If you drill it, it might fall out, so best to find another place or another timber.....

    I agree. Don't drill through a knot if you can help it.

    Clamp pieces of scrap wood on both sides of the knot. Then drill the hole. With some luck, the knot might not fall out. You can also try sealing the knot with shellac first. If you are inserting a screw, it may split the knot no matter what you do.

    If the knot can be wiggled with your finger, it's loose and will probably fall out when pressure is applied while drilling. If the knot is tight, try putting a piece of scrap lumber under the knot, and start drilling using a 1/8" drill bit in an electric (or battery powered) drill. Dont be in a hurry, knots are super dense compared to the rest of the wood. After the initial hole is completed, go up to a 3/16" bit and follow the pilot hole thru the knot. Repeat this procedure until you have the size hole you want. A caution, if this is for a screw, plan on a countersink bevel at the top of the hole to accommodate the underside of the screw. If you dont, the screw will split the knotas it gets flush with the surface.
