[TheForge] drilling 3/8 rod

[Ralph Sproul]

Don, Two V blocks with a hole drilled in the top block.  Make sure to keep
your reference mark at high noon to keep the holes in a straight line.

The V'blocks I'm talking could be nothing more than a block with a slot for
the bottom to keep clearance for the top one(and clamp that into your drill
press vice).  The top obviously would need to be more of the deeper V to hit
the sides of the bar to keep the alignment for the hole drilling which will
make it tend to wander. You might even be able to use a small piece of angle
iron for the top jig......drilled from inside the V in a V block to keep it
centered.   Should be accurate enough with what you've got to work with.
