ah ok so I think we should make ourselves some sort of are mounted hydraulic glory
crushy choppy thing gay right suppose we should do some care then college
down this channel cat means cardboard aided design so got some cardboard really rubbish
scissors oh good gun call it with all these professional tools you've gone
your all resort into a glue gun are we doing here then first I'm gonna hold some I don't
want to slide my hand into it grab the toilet roll and then around my hand we various bits
of metal hydraulic cylinder underneath push a button probably on the end of the toilet
roll kind of like the jaws of life only they tend to open or crush I don't know really I
suppose they do both there and and this here we get off by the time I've finished it would
probably be so every I want me to lift my arm up let's start chopping and cut in
yeah it's like fish now we've got all this sir support round it because obviously when
the hydronic round which can attach under ear Bush is it shut it's good if there's
anything in it rather than cushion it's gonna want to push this apart want to
crush all this and this is kind of there for reinforcement I'll try and make it look a bit
more streamline in a bit better than that luck it's like a rare kind of a Batman wait
fishy things that they're all right so now I'm going to do draw this on the computer
will cut out on the plasma cutter I start welding it together and see what happens
is it gonna work now if your new area I'm wondering what I've just
connected to under the bench there's a hydraulic pump set up in there under
there there's a link I'll stick a link at the end of the Year video so you can
go see how that has been installed now we've not got a sharp edge on it yet so
very fun ah it's just broke we could join everyone your arm in it oh of course yeah
that's how he's swinging off that bit in it mmm yeah go strengthen that up a bit foes
they are this first test you will crush my arm as well in there you're not finished yet Kali
okay I finally got there with the old strength from reinforcing we try putting some extra plates
on here that still didn't do it put this extra one wrong on bottom here that's still didn't do
it so I'm about to give in and put cross brace across it I didn't really want to do that for
some reason I wanted it all to be strengthened the in the top there but of course we've got
like four tons of pushing strength you know that was never gonna take four tons of pushing string
without it collapsing so if I get a bit of wood we now have a chopping machine I'm also sharp
and this bit up a little bit which is nice so for putting this in here yeah any problem we've
got now of course is I am connected to the hydraulic system under my bench so I cannot
go anywhere over than in here or however long my holiday holic hoses are so well I think we should
do let's put a pump in a backpack I think this is gonna add a few kilos on to my body mass isn't it
hey it's not to be leaking you can see on the little 3d printed thing there's our ring that
went round the air the outside of it give it a wipe up usual hydraulics bloomin oil
everywhere now I've installed a switch into the handle I've got these wonderful short cables so
let's connect the battery up I'm gonna do this hey boy how hot are the cables gain no
not too bad I think all we're gonna do now is stick this on me back put this on me arm and
I've got married hydraulics nipper for what I don't know but who doesn't want one of those
right yes Oh put your and they're scary right then what we got now of course we got a same bit
of wood better would not a problem right what about a stick a bit of 1/3 back to okay so as
a wood cruncher this thing is fantastic and the fact it's mobile means I can crunch would anywhere
but there are improvements we made because we want to be able to destroy anything if I trying
to chop some bits of metal look it basically just crushes it which is very nice now this is not what
we want we want to be able to chop through stuff so I made a different set of jaws which look a
bit like the guillotine so they slice rather than try and snip and works pretty well on soft metals
but on harder metals the whole thing just splits apart and there's basically too much slack in this
area so we need to beef that up okay as a first attempt I'm pretty pleased with this it looks
awesome and it's a great example of cobble wood aided design but we need to beef up this heating
system I think it'd be quite nice to have a bigger hydraulic cylinder so we've actually got a little
bit more power I'd like to make a bit lighter if I can because it's a it's pretty heavy at the moment
and I think once I'm happy with the design I'm gonna get Alex tail you choose resident blacksmith
mm well to whip me up some nice hard and proper steel strong jaws and teeth for it so they'll be
coming up soon subscribe you don't want to miss that and then next week I don't even know how
to explain what we're doing next week it involves a pole share and a JCB yeah stay tuned stay tuned
