oh boy have I got a fun one for you
today today today today today we are
going to learn how to screw two bits of
wood together this is two minute Tuesday
so back in the days when I used to
skateboard we used to like rob grannies
we used to smash window and joke and we
didn't do any of that we used to build
ramps and we always struggled with the
bit we put the screws in because the
material would sometimes separate you
now heads poking out it was a bit
dangerous and a bit dodgy so this is how
you do it properly two minutes on the
clock
let's go okay so like I said what a lot
of people do at this point is they'll
just pick up the screw and they'll pick
up a drill that looks a little bit
smaller than the screw they'll pile it a
hole through that pilot a hole through
that and then screw it together but
sometimes when you do this that material
starts separating and you have to bring
the screw out and then back in and then
out back in and it will eventually start
binding it up but there is a proper way
of doing this so if you look at a screw
you've got the head you've got the shank
and then you've got the threads which
are along that shank so when we're
drilling the pilot hole we want the
drill to be exactly the same size as the
shank so this one I'm holding now I just
picked out of my box if you look at it
it's actually ever so slightly smaller
this is a two mil drill bit however I
reckon if I switch to a 2.5 you might be
able to see that that looks a lot better
so it's of similar size to the shank and
you can still see the threads of the
screw poking out either side so that is
our perfect pilot hole so if we were
screwing these two bits of material like
that the pilot hole would go through
here and through this component as well
so let's just do that quick this is
where a lot of people will just leave it
perhaps they'll countersink the top here
so that you can let the head into the
top of this wood but you still have the
problem of the material being pushed
apart and this is where a clearance hole
comes into the clearance hole we do the
same size if not a tiny bit bigger than
the threads on that screw so this is a
four millimeter by thirty screw this is
a four millimeter drill bit so the
clearance hole is going to be drilled
through this top component here so I'm
going to do a little test fit
perfect so it's a really nice fit in
there so now we have three clearance
holes that the screws can go straight
into like that and then they will still
bite into this component below however
the heads are still sticking proud of
the surface so this is where a
countersink comes in now a countersink
is simply a cone-shaped drill bit that
matches the angle on the top of the head
here so if I put this in the drill make
sure they're all located in there and
then simply get your screw put it on a
low torque setting and there you go nice
stress-free joint no gaps whatsoever
heads below the surface I think we are
done oh there you go that is a technique
that I wish I knew in my skater days it
would have saved me a lot of effort and
risk crunch trying to screw those in by
hand but yeah that is how you do it
effectively little plug here I'm it's
not even an affiliate link for these
whatsoever but Axminster sell these
screws called would spur or under the
name would spur and from what I've heard
from tradesmen carpenters furniture
makers they absolutely love them because
they are brilliant for the money for
heads don't shear off their self-tapping
self countersinking have a look at
because if you don't like the cost of
screws from like your standard home
supplier they are really good bet a lot
of people like in the moment so there
you go
something for you to look into there
otherwise we're all done see you in the
next video
