Now, an interesting problem has come up. The blind bottom holes are very
shallow, and the tap doesn't go far enough in to cut enough threads to make
me feel comfortable. As you know, the tap is the largest about in the
middle, so you really need to have the middle part go all the way to the
"bottom" of where you want threads.
Possible solution -- buy a second tap, and cut it off a third of the way up.
Use the first tap to get started, and the second to finish the job? Is that
possible? and can you even cut through these taps? Or is there another
obvious solution?

Bruce,
Have you checked out a tap designed for bottomed holes? Most
people aren't aware that there are actually two types of hole
taps. One for through holes, and one for bottomed holes. Check
it out, it should help.
