Tom Cobble sent me a series of photos of this very procedure a few years 
ago. I've never used it, but here are my choices of those photos to best 
demonstrate the procedure (for us rookies!) 

If you hover over any given photo a little description will display.

The initial through-hole should be as close to the diameter of the spade 
bit as possible, without being smaller... a little larger is ideal.  After 
boring out the recess for the T-nut, you can chase out the through-hole to 
the diameter needed for the T-nut.
