Drilling end grain of long 2x4

I'm trying to drill a 1/4" hole 2" deep into the end grain of a 2x4.
I could see using a drill press, except that the board is over 100
inches long, and there's no way to get a drill press over top of it.
Is there a standard solution to a problem like this?

Any help will be greatly appreciated,
Zach

Use the drill press to make a hardwood block with your holes at
perfect 90 degree angles.

Use the block to keep your hand drill straight on the 2x4's.

My my, we would appear to be blessed. Just checked google, and
this looks like your first post on the web anywhere, ever.

You could always lie the drellpress on its side. Or cut the 2X4
short enough to fit under the drillpress. Or you could lift the
drillpress up, maybe put it on a balcony, or something.

Most of the time when I'm doing something like this, being off by 10
degrees in any direction doesn't matter. The adjuster foot will still
sit plenty firm on the ground. If this is the case, get yourself a hand-
held drill driver and just free hand it. Line your bit up parallel with
the board edges, and just try to keep it as straight as you can.

If precision does matter, I'd take Phisherman's suggestion. If you're
making several 1/4" holes, you may want to consider purchasing a metal
tube that fits your bit. A hand-held drill driver will make the cut just
fine, then.

(Btw, the reason I mention the driver part is simple: If you get a new
tool you'll get more use out of a drill/driver than just a drill alone.)

I've used this to good effect for drilling relative straight and accurate
holes in awkward places:

Pull the drill press head off the column and pull the table off, too.
Replace the head upside down, as far down on the column as you can.
Replace the table upside down too and swivel it to 90 °. (You will need
overhead clearance). Clamp the 2 X 4 to the table, square it up, and
drill.

I would use my dowel jig with a long 1/4" high speed bit. Forget the
electrician augers.

My second choice would be my brace and bit, but I don't know if the auger
would work.

Thanks everyone. To clarify: I am going for accuracy on this
particular project. Ideally, I'd like holes that are within a degrees
or two of "true" in both the X and Y axes (I'm not sure if there's a
better woodworking term for this).

I'm glad to know my intuition was close on this one -- I first tried
using a short piece of predrilled 2x4 (clamped to the end grain of my
workpiece) to guide the drillbit. However: my drillbit was definitely
too long (I was using one of those electrician's bits that's used for
plowing through whole walls and floors), which allowed me to
accidently get too much lateral leverage, leading the bit astray. I
also didn't use a metal guide tube. I like this idea. I'll get a
shorter bit and try the tube idea today.

Thanks everyone.

Cut off a 2" or so piece of 2x4 scrap

drill hole through that piece with drill press, that will act as a guide for
the good hole

Lay your good piece someplace flat

align drilled scrap piece with end

use a couple of other 2x4s on each side, overlaping the joint, clamp, and
drill through the hole in the scrap, and there you go!

Shop Smith. Thats one of the few reasons I kept my old (10er) Shop
Smith. You can configure it for horizontal boring.
Another reason I kept it was for the wood lathe feature.

1/4 inch 2 inches deep a cordless DeWalt would handle just fine.

If it has to have precision of alignment or depth a radial drill press
would do it. Just rotate the head to 90 degrees and make a support
for the board.

A .25 caliber pistol would be another option <eg>.

For production work one would use a horizontal boring machine unless
the volume was high enough to justify custom made tooling.

McMaster, Grainger, and Fastenal all list 6" 1/4 inch bits. You might
want to pick up one of those--the length is enough to give you good
purchase on the jig but not so long that you're likely to lever the
jig off center.

For the accuracy you're describing and lacking a drill press with
horizontal boring capability you might want to consider making a
cradle for the drill that holds it securely with the bit horizontal to
the limits of your ability to measure and parallel to a fence again to
the limits of your ability to measure, then move the piece into the
drill, aligned by the table, the fence, and such other guides as you
might want to use (a couple of featherboards for example).

You don't say what tools you have available--hand held drill and drill
press you've mentioned, but you may have something else that allows
this to be done very easily once it occurs to you to use it for the
purpose, and possibly with the addition of a chuck.

Construct a wooden jig that slips over and clamps to end of the 2x4.
The jig aligns the bit of your hand-held drill (similar to a Kreg
pocket-hole jig).
