If it were easy everybody would be doing it.
You could set up a jig for your router and create a deep mortise in the
top of the leg and glue in a plug with polyurethane glue. Just make
sure the grain of the plug is going the same direction as the grain in
the leg, and if possible set the mortise at least a quarter of an inch
from the outside edge of the leg, other wise a thin bit of material
will just split away in another spot when the wood decides to move
again. Good Luck!
Part of the joy of furniture building is the oppertunity to solve
problems. That is why I gave up my job in industry, to do it full time
years ago. Just didn't want to take another order for the same old
blah, blah, blah, widgit. Give me a tough problem to solve anyday over
On the other hand, I notice minor anomalies in my pieces, and others,
because my eye is trained for it. My wife and I went to visit some
relatives who had lived in their house for four years, but had never
noticed that half of the turned posts in the balcony railing had been
installed up-side down.
