In this video
we're going to remove these two broken screws and that we're going to repair that so that
we can put the screws back in this is a very common problem you tend to get screw snapping
like that in certain circumstances if you've ever tried to remove a decking screw for example they
are notorious for braking as soon as you try to unscrew them the head just normally
shears right off with this I've just rigged this up to the demonstration on the bench
so I'm going to remove the final screw there
and then in the other two holes we've actually got a broken screw and they are the two screw heads
in order to remove the two screws I'm going to use one of these which
is a diamond coated hole saw these will cut through almost anything
if the screw is sticking up above the surface you can simply use that like so
and the actual screw will stop the drill bit from slipping all over the
place in this example we're going to have to use something like that so I've simply
drilled a seven millimeter hole in a piece of scrap wood we can align that over the hole
and then clamp that down and then we can use that as a guide to get the screw out
there may be some places where you can't use a clamp if that's the case you can
simply drill a couple of holes in that and screw it into position temporarily
so we've now got the drill and we're going to proceed to drill out the broken screw
once we get the hole started we can actually remove the guide
and then we're just going to continue to drill that out basically this is grinding away the wood
as you can see the wood is a little bit
burned,which is to be expected
if the actual hole saw gets clogged up with sawdust you will have to take
that out you might have to clean it out using a small diameter drill bit
and it does look like we've actually drilled it out there now you will need
something to push out the broken screw I'm going to try using this welding electrode
and there is the snapped screw
we now just need to repeat that on the other snapped screw
and
again,
we've removed the screw
you have to watch these they do get a little bit warm when you're using them in wood
and the screws actually been pushed right out the back that time so we can just pull that straight
out now we just need to get a couple of dowels and the correct sized drill bit which in this
case is eight millimeters I'm then just going to drill the holes out to the correct diameter
for this demonstration I'm just going to use some super glue because
my wood glue is on a job and it's about 30 miles away can then push that in there
I
can actually wipe off the excess
once the glue's dry we can then cut them off flush I'm going to use this multi-tool
if you don't have one of these you can of course use a sharp chisel
We can then align
that back up put the screw back in
and then we can take a hinge siting drill
just put two pilot holes in there
and then we can put two brand new screws in ensuring that we've got
the drill driver set on a low torque setting
so that's it we've removed the old broken screws put some dowels in
and inserted some new screws I hope you found this
