I'm going to show you how to cut purse
back to easily a lot of large
manufacturers cook perspex on large
industrial machines laser cutting
machines and even water jet cutting
machines which makes it easy when you
consider it at all you're limited really
to a circular saw or a jigsaw but you
can use a motor for cutting straight
lines I like to use a circular saw and
for curved lines I use a jigsaw it's
real easy to call there's nothing hard
about it and I'm going to show you how
to do it and also going to straightedge
I you can see that this edge here isn't
straight to begin with so firstly we're
going to cut a new wedge on there and
get it nice and straight so cuts a
straight edge along here
we're going to use these clamps and a
piece of angle iron to give us a
straight edge one thing you must do when
you're cutting perspex is leave the
masking on never remove the masking
until you've finished making what you're
making have else it will scratch quite
easily here you can see that up for a
straight edge on the top of the perspex
and I've used a clump at each end to
secure it you can see there the blade
sticking to the perspex quite a lot we
don't want up that means that you're
wasting a lot of energy going through
the material this is the same if you're
cutting wood you need to adjust the
blade so that you just cause through the
surface at the other side so we're just
going to adjust that off so about there
and that's just going to cut through the
surface of the perspex which is what we
want if you have the blade sticking all
the way through your waste a lot of
energy on friction you should always
wear safety glasses as well when you cut
in any material or if you're using any
power tool it's really good ideas put
some safety glasses on
another important point when you're
cutting perspex is never to let the
blade touch the perspex before you start
the machine if you do it's going to chip
it quite badly so always get the machine
started before you touch the perspex
so call this radius we're going to use a
jigsaw it's quite um difficult in color
of lines in perspective can really use a
circular saw for doing anything like
this you're going to need a metal
cutting blade for cutting perspex or
water cutting blades Nagaland perspex
