blind rivets are an extremely good way
of fixing two thin pieces of metal
together in order to use them you will
need a blind rivet gone like this these
are also referred soot was pop rivet
guns after the original firm that
invented them so when you get the gun
and you need the rivets which I like
that and you also only need a drill bit
of a suitable size for the rivet that
you're using if we take a look at the
gun you'll see that it has a nozzle at
the top there and that is where we place
our rivets so that goes in there before
you actually pull the Mundell back out
using the rivet gun you'll also notice
that there's three other nozzles on the
gun and they are four different size
rivets so whenever you choose the nozzle
for the actual gun itself you need to
choose a good fitting one so for example
that with it there won't even go in
there so that is too small of a nozzle
it won't go in that one it'll go in that
one but it's extremely tight so that's
not good and it will fit in that one
perfectly what you don't want to do is
get one that's too slack so obviously if
you put a small rivet in that one that
is a wrong nozzle and that is also a too
loose so it needs to fit in there and it
needs to be a nice needs fit so that one
is a nice tight fit so we know that that
is a correct nozzle for that size of
rivets these guns also usually come with
a spanner which fits on there and you
can just unscrew the nozzle and then you
can swap that for a different sized one
which is further down the gun here so
you would just unscrew that and then
screw that in the if you were using that
size nozzle
pull that back in there we'll just nip
that up so once you've chores on the
correct size nozzle for the livet that
you use in your den need to choose the
correct drill bit so I forget that drill
bit and all that against a rivet there
you can see that that is roughly at the
right size if you use a drill bit that's
too big your rivet will not hold
correctly in the old at your drill so
it's important that you choose the
correct size a little bit
so I'll power plant two pieces together
and now I'm just going to put the drill
through these two pieces
so we can now push the rivet into the
rivet gun if you just squeeze the
handles gently it will grip the river
and stop it falling out so we can now
put it up through the oil and then we
can then squeeze the ambles together
until the river Chi is off so if we take
lot from you on this side you can see
that when the Andals are squeezed it
pulls back on the mandrel distorting the
rivets which make it expand and then the
mandrel shears off so when you put in
the gun is squeeze the levers it pulls
this metal mandrel up which pulls that
mushroom ed through the rivet causing it
to offset it which makes it expand and
that actually grips it
the river is then stuck in there because
the actual mandrel shears off at a
predetermined torque the may come a time
when you need to remove a rivet and the
best way to remove remove it is to drill
the EDD off so I've got a drill here
that is Fox not of the same size as
deliver ed so if we drill at which
you'll be able to drill the edge off the
rivet and then we can remove the piece
of material that's fastened together
