if you've ever tried to drill
perpendicular holes in stock and you
without a
press you know how difficult that can be
I'm going to show you three ways you can
do that without a drill press and still
get some really good results but before
we do that I'm going to talk a little
bit about drill bit selection there's
lots of twist drill bits available and
most commonly or the standard twist
drill bit everybody's got them but for
woodworking I'm gonna recommend that you
go out and invest in a set of Brad point
bit now you can pick up a cheap set you
don't have to buy a set of thirty bits
you can buy a set of seven or ten pretty
economically the other type of bid is a
bullet point bit also pretty good for
woodworking and the advantage these two
bits are going to give you is that they
have a point on the end it's going to
help that bit from skating all over the
surface and without a drill press I
think you need that extra control the
first method I'm going to demonstrate on
drilling holes is using a standard
doweling jig now these are available
just about anywhere one of the strong
suits of a doweling jig obviously it was
designed for drilling the edges of
woodwork pieces now today I'm going to
show you a little bit about how to use
it drilling on the face of these
surfaces okay before we drill holes
first things we need to do I've already
laid out my location lines that I want
my holes and I've also taken the time to
do a depth stop and this can be as
simple as a piece of tape just indicates
once the tape hits the top of the
bushing or the top of the jig you don't
need to drill any further down a jig as
pushing it along the top and these
bushings have different sizes for
different bits and they're indicated on
the side here we're going to drill
quarter inch holes so I've got a quarter
inch bit I'm gonna use a quarter inch
bushing let's drill some holes so we'll
lay the jig down on the workpiece and
I'm gonna Center that looking down
through my bushing I'm gonna look down
to do that hole and Center it up with
that mark when I put that Brad point
right on that cross you're ready to
drill
next method I'm going to show you is
using a hole drilling guide now this kit
comes equipped with a clear plastic base
now it also comes equipped with these
metal bushings it's got about five or
six sizes you can use so it gives you a
little more versatility than a doweling
jig
now like the doweling jig this system
also will allow you to drill holes in
the edge of a workpiece simply drop the
two pins or two nails through the base
and basically twist it so those nails
are tight against your wood surface now
we're ready to drill holes and the
surface of our piece of wood with this
jig and because of how you lay it out
you need to extend your layout long
lines a little longer as I have already
done here
it's simply place your jig down on the
workpiece and then you're gonna line up
as many of these corners as you can with
the four corners of the jig start your
village brilliant guide gives you a
couple other options for drilling holes
and still perpendicular this indentation
of the bottomless base allows you to
actually drill at a 45 degree angle on
the edge of a board same process you
know you line up your your lines
insert your bushing and drill your hole
another little neat little option with
that groove cut in there is it allows
you to drill round surfaces I have to
secure it on there but you can actually
drill down with the same process and
lastly because this is concave in this
bottom it actually allows you to set
this over a ball and drill a hole to
ball making it a pretty versatile little
jig the third method I'm going to talk
about is a simple homemade shot version
you don't to buy anything basically a
couple screws and some glue and some
scraps in your shop you can come up with
a really simple jig that will ensure
some pretty good results now a couple of
things with this jig you want to make
sure you get a perfect 90 degrees in
your corner the other thing is 90
degrees from the base to the face that's
also pretty important one neat thing
about this jig the other jigs didn't
provide it really doesn't limit you on
the size of drill bit you can use so it
does have some versatility with this jig
basically what we're gonna do is take
your brad point bit and line it up with
that cross here and then
simply move the jig into place making
sure it's flat on your work surface and
keep that bit down in the corner and
you're ready to drill okay there you go
I've shown you three different ways that
drillin holes perpendicular to surface
now someday maybe you do buy a drill
press don't throw these jigs away
because they do have a home in your shop
for specialty situations things the
drill press can't do
you
