Wade,
I am heading in the same direction as you. One Idea I had was to tram (square up) my drill press spindle to the table top. What I mean here is to invert the base so the spindle can reach the table top and move the spar along the table while drilling. That looks like the easiest way to keep it supported while drilling.
Below are 3 pictures of my shop, table & workbench. The workbench has adjustable shelves. Looks like I may not have to invert the base because it fits under the table. I may have to use several positions, and tram in the spindle at each location.
Carlos, what do you think?

Hi Wade.
Here are a few tips. I also have some photos if you
want some. Email me offlist.
Number 8 and 10 machine screws with wing nuts make
great clecos as you drill. (be sure to use washers on
both ends to avoid marking those spar caps)
I always started with a smaller bit and did a pilot
hole first. More drilling overall but all my holes
are round so I think it was worth it.
I turned the drill head on my drill press 90 degrees
and clamped the base to a small table beside my
worktable. This allowed me the reach I needed. Then I
slid the spar along the work table and drilled as I
went. It worked well. It is important that the spar
remains flat (straight) throughout the drilling
process or you will build in some warp.
I use a small piece of angle or some other suitable
tool to check that the drill bit is square to the spar
cap in both directions. If the hole isn't square to
the material the heads of the rivets don't sit right.
Polish those spar caps. There should be no nicks or
scratches in them whatsoever as that is where stresses
will build up.
I hope that little bit helps. A lot is common sense
but spars are a lot of work and absolutely crucial to
the structural integrity of your airframe. I would
hate to see anyone make a set that were not airworthy.
have fun.
David
