    Dean;
    Make up a fixture from angle iron a little longer than the
part you are drilling. With the open side of the vee up, weld
it to a plate that can be clamped to the drill press table or
clamped in the machinist vise bolted to the table. Drill a 1/4
inch hole near one end of the angle through the bottom of the
vee so it can be mounted securely at the proper distance to
drill the second hole. Drill the first hole then turn the rod
around and insert a bolt or pin through the drilled hole into
the pilot hole in the angle iron and drill the second hole.

                    Gene

: I would like to get some help on how to set up a drill press
to do a small
: amount of repeat drilling. I'm not a machinist but I know
there must be a
: simple way to set up a fixture or jig so that I can produce
several
: identical drilled parts using a drill press.  I do have a
large and small
: machinist vice that I can lock down on the drill press table.
:
: As an example I need to drill two 1/4" holes near the ends of
a 3/4"
: diameter steel rod. The critical dimension is the distance
between the holes
: not the distance from the ends of the rods. The tolerances
are not tight. If
: I can get within + or - 0.100" between the holes I would be
ecstatic. I am
: cutting the rods to length with a steel band saw so the
lengths of the rods
: will vary a little bit and that isn't critical. I would like
to get the
: holes at each end of the rod fairly centered, end to end but
the dimension I
: need to control is the distance between holes, center to
center.
:
: Is there a simple way to fixture this so I can get some
repeatability and
: consistency with the tools I have available to me? I suspect
those of you
: who are machinists or have machinists skills have had to do
this several
: times.  I'm a shade tree mechanic trying to do something I
don't have
: experience doing. Any help would be appreciated.
