Why do wooden dowels have grooves?
The grooves provide reduced contact area between the dowel and the walls of the hole, and at the same time they provide channels for any excess glue if you didn’t drill the hole slightly deeper than the dowel.
Why are dowels fluted?
The second explanation is the dowels themselves: fluted instead of spiral-grooved. Because they allow excess glue to squeeze out when the parts are clamped – that is, to not be trapped at the bottom of hole, which would prevent the dowel from penetrating deep enough.
How do you fix a loose dowel?
If your dowel is now too small for its hole, wind cotton or linen thread around the tip of the dowel to make it thicker. Then coat the wood and thread with glue, and reassemble. Another way to fit a shrunken dowel into the hole is with a shim. Shims can be purchased where wood is sold.
Are dowels strong enough?
It’s nice to know that dowels can provide a strong option when making furniture or cabinetry.

I would also highly recommend a dowel jig and/or dowel centers. When creating dowels, I like to align my boards by clamping them together with the sides that will eventually have the holes facing out.
