I've got a little Ryobi bench top DP that does a great job on the little
stuff I do. Today, I needed to bore some very straight 3 inch deep
holes in the end of a 1x6x18. With the bit in, I just had 12 inches of
clearance between the bit end and the base, so I ended up using the
handheld. I got it close enough, but not perfect. Was there any other
way to attack this short of unbolting the column from the base and
rigging a temporary column extension? I actually thought about doing
that but for two flippin' holes? No way.

assuming the ends of the 1x6 are square and a long drill bit (6-8"
long) is available, I believe I'd use the DP to drill holes at the
desired location in the end of a short section of 1x6 ( 2 to 3 inches
long?). Then clamp the short section of 1x6 end to end with the longer
piece and use it as a drill guide to locate and align the holes in the
long piece. A couple of pieces of scrap running the long way on either
side of the 1x6 will give a place to apply clamps as well keep the
short piece aligned with the long piece.
Not a very robust drill jig since the holes in the short piece will
rapidly be enlarged/elongated and useable for drilling only a very
limited number of holes in the long piece. But I've done similar for
very short production runs with good success.
I did what Lew suggested when I had to do that. The problem is, when
you do that you've got no table now to get you square with the drill
bit, so I ended up using a square and clamps and a mickey mouse setup
to do it, and I ended up just like you; close enough, but not perfect.
