Steel workers who erect the skeletons of big buildings, bridges
and similar use something called a that has a tapered spike for a handle. They use that
tapered handle to lever holes into alignment so they can get a
bolt through. Same idea on a different scale.

The tapered holes for alignment pins are made by drilling and then
reaming with watchmakers cutting broaches. You can buy them
individually
or in a set from watchmaking tool suppliers, who also sell the
tapered pins.

Seems like a very smart solution.
Does anyone use these? Do you drill the holes (with a taper
drill), or
use a reamer?
And any other equally smart solutions to achieve the same thing?
