with the base cut the next step is to
with the base cut the next step is to cut a one inch strip at least 16 inches
cut a one inch strip at least 16 inches
cut a one inch strip at least 16 inches long my board is about two feet long so
long my board is about two feet long so
long my board is about two feet long so I’ll cut my 1 inch strip 24 inches long
I’ll cut my 1 inch strip 24 inches long
I’ll cut my 1 inch strip 24 inches long and then trim it down to 16 inches
with our base in our launch arm cutout
with our base in our launch arm cutout we now need to cut out the two side

we now need to cut out the two side supports these are going to be two
supports these are going to be two
supports these are going to be two triangle-shaped pieces that are tall
triangle-shaped pieces that are tall
triangle-shaped pieces that are tall enough that at 10 and 1/2 inches we can
enough that at 10 and 1/2 inches we can
enough that at 10 and 1/2 inches we can add the axle it’s not terribly important
add the axle it’s not terribly important
add the axle it’s not terribly important that you match any particular shape with

it will easily slide from side to side
it will easily slide from side to side this is where we’ll use those nuts and
this is where we’ll use those nuts and
this is where we’ll use those nuts and washers to help keep it centered right
washers to help keep it centered right
washers to help keep it centered right in the middle we’ve got some nuts and
in the middle we’ve got some nuts and
in the middle we’ve got some nuts and washers on our axle it still spins
washers on our axle it still spins
washers on our axle it still spins beautifully but now it has no play to
beautifully but now it has no play to
beautifully but now it has no play to either side as a next step let’s attach
either side as a next step let’s attach
either side as a next step let’s attach a hook to the back of our throwing arm
a hook to the back of our throwing arm
a hook to the back of our throwing arm that we can use to hang our weight from
that we can use to hang our weight from
that we can use to hang our weight from now I’ve driven that i hook almost all
now I’ve driven that i hook almost all
now I’ve driven that i hook almost all the way down the loop is now touching
the way down the loop is now touching
the way down the loop is now touching the wood to be sure we have a way to
the wood to be sure we have a way to
the wood to be sure we have a way to attach our weight now let’s use a small
attach our weight now let’s use a small
attach our weight now let’s use a small pair of pliers and try our eye hook open
pair of pliers and try our eye hook open
pair of pliers and try our eye hook open a little bit so it’s more of a hook and
a little bit so it’s more of a hook and
a little bit so it’s more of a hook and less of an eye to make sure it’s open
less of an eye to make sure it’s open
less of an eye to make sure it’s open far enough let’s see if our large eye
far enough let’s see if our large eye
far enough let’s see if our large eye bolt can fit down into the gap looks
bolt can fit down into the gap looks
bolt can fit down into the gap looks like it fits just great now to make our
like it fits just great now to make our
like it fits just great now to make our weight let’s take our eye bolt load it
weight let’s take our eye bolt load it
weight let’s take our eye bolt load it up with washers and add a few nuts on
up with washers and add a few nuts on
up with washers and add a few nuts on the bottom to hold them all in place we
the bottom to hold them all in place we
the bottom to hold them all in place we now have a nice weight try hanging that
now have a nice weight try hanging that
now have a nice weight try hanging that on the end of our trebuchet and see what
on the end of our trebuchet and see what
on the end of our trebuchet and see what happens if we let go well partly that’s
happens if we let go well partly that’s
happens if we let go well partly that’s what we wanted to happen I guess we need
what we wanted to happen I guess we need
what we wanted to happen I guess we need to close the hook over our loop once
to close the hook over our loop once
to close the hook over our loop once it’s attached before I close that on
it’s attached before I close that on
it’s attached before I close that on though I’m looking at the speed of this
though I’m looking at the speed of this
though I’m looking at the speed of this and I think it would be better if we
and I think it would be better if we
and I think it would be better if we could get it to launch just a little bit
could get it to launch just a little bit
could get it to launch just a little bit faster than that that’s not a ton of
faster than that that’s not a ton of
faster than that that’s not a ton of speed on there so I think I want to
speed on there so I think I want to
speed on there so I think I want to increase this weight by a little bit
increase this weight by a little bit
increase this weight by a little bit these are very small thin nails that are
these are very small thin nails that are
these are very small thin nails that are designed to go in an electric nail gun
designed to go in an electric nail gun
designed to go in an electric nail gun but I’m just gonna use them as a little
but I’m just gonna use them as a little
but I’m just gonna use them as a little bit of weight today so I’m just going to
bit of weight today so I’m just going to
bit of weight today so I’m just going to take several of them put them together
take several of them put them together
take several of them put them together and tape them onto our weight that we’ve
and tape them onto our weight that we’ve
and tape them onto our weight that we’ve already made
all right that is considerably heavier
all right that is considerably heavier almost double the weight that I had
almost double the weight that I had
almost double the weight that I had before let’s see if our launch speed
before let’s see if our launch speed
before let’s see if our launch speed seems to have changed at all that’s a
seems to have changed at all that’s a
seems to have changed at all that’s a much better swing around I like that way
much better swing around I like that way
much better swing around I like that way more
more
more all right let’s attach our weight and
all right let’s attach our weight and
all right let’s attach our weight and then close off our eye hook so they
then close off our eye hook so they
then close off our eye hook so they can’t fall off on back and boom
can’t fall off on back and boom
can’t fall off on back and boom beautiful launches and it doesn’t fall
beautiful launches and it doesn’t fall
beautiful launches and it doesn’t fall off the two things we were looking for
off the two things we were looking for

currently the nail at the top of the swing arm is pointed basically straight
swing arm is pointed basically straight
swing arm is pointed basically straight up the angle of that nail has a lot to
up the angle of that nail has a lot to
up the angle of that nail has a lot to do with at what point the washer will
do with at what point the washer will
do with at what point the washer will slide off of it so it’s entirely
slide off of it so it’s entirely
slide off of it so it’s entirely possible that right now with the angle
possible that right now with the angle
possible that right now with the angle it’s at it might shoot too straight up
it’s at it might shoot too straight up
it’s at it might shoot too straight up or even launch early let’s find out all
or even launch early let’s find out all
or even launch early let’s find out all right

right first test fire in three two one Wow
first test fire in three two one Wow
first test fire in three two one Wow well it didn’t shoot straight up it shot
well it didn’t shoot straight up it shot
well it didn’t shoot straight up it shot at just about a 45 degree angle which is
at just about a 45 degree angle which is
at just about a 45 degree angle which is kind of what we want so it’s working
kind of what we want so it’s working
kind of what we want so it’s working pretty well we just need a better launch
pretty well we just need a better launch
pretty well we just need a better launch space guess let’s take this outside and

see how far it goes now we let this go
see how far it goes now we let this go in three two one we oh wow I worked
in three two one we oh wow I worked
in three two one we oh wow I worked pretty great 23 23 feet not bad let’s
pretty great 23 23 feet not bad let’s
pretty great 23 23 feet not bad let’s see if we can do it again
see if we can do it again
see if we can do it again firing in three two one whoo launched

right that was pretty cool this thing
right that was pretty cool this thing has some pretty good distance on it but
has some pretty good distance on it but
has some pretty good distance on it but there’s a little modification I want to
there’s a little modification I want to
there’s a little modification I want to make I want to add some real power onto

adding more weight I think there is a
adding more weight I think there is a limit I think it’s around 130 times the
limit I think it’s around 130 times the
limit I think it’s around 130 times the weight of the projectile is how much
weight of the projectile is how much
weight of the projectile is how much weight you should have on the back for
weight you should have on the back for
weight you should have on the back for ideal launching but I want to see what
ideal launching but I want to see what
ideal launching but I want to see what happens if we add spring power to it not
happens if we add spring power to it not
happens if we add spring power to it not just a weight but something really
just a weight but something really
just a weight but something really pulling on the string as hard as it can
pulling on the string as hard as it can
pulling on the string as hard as it can to add a little bit more power to our
to add a little bit more power to our
to add a little bit more power to our trebuchet we’re going to try using a
trebuchet we’re going to try using a
trebuchet we’re going to try using a spring loaded rat trap this thing will
spring loaded rat trap this thing will
spring loaded rat trap this thing will pull on our trebuchet arm with a ton of
pull on our trebuchet arm with a ton of
pull on our trebuchet arm with a ton of power hopefully it doesn’t break it but
power hopefully it doesn’t break it but
power hopefully it doesn’t break it but we should be able to get some incredible
we should be able to get some incredible
we should be able to get some incredible distance and maybe some larger
distance and maybe some larger
distance and maybe some larger projectiles using this
[Music]
[Music] now to make sure the rat trap is pulling
now to make sure the rat trap is pulling
now to make sure the rat trap is pulling the string the right direction
the string the right direction
the string the right direction when it fires our trebuchet let’s add a
when it fires our trebuchet let’s add a
when it fires our trebuchet let’s add a small eye hook down at the bottom that
small eye hook down at the bottom that
small eye hook down at the bottom that will help direct the string so it’s
will help direct the string so it’s
will help direct the string so it’s pulling in the same direction as gravity
pulling in the same direction as gravity
pulling in the same direction as gravity instead of pulling sort of sideways okay
instead of pulling sort of sideways okay
instead of pulling sort of sideways okay I’ve got the eye bolt installed and I
I’ve got the eye bolt installed and I
I’ve got the eye bolt installed and I offset it a little bit so it’s not quite
offset it a little bit so it’s not quite
offset it a little bit so it’s not quite in the middle of the path this I’m
in the middle of the path this I’m
in the middle of the path this I’m hoping will allow the firing mechanism
hoping will allow the firing mechanism
hoping will allow the firing mechanism to still pass through a whole trebuchet
to still pass through a whole trebuchet
to still pass through a whole trebuchet without getting caught on the eyeball as
without getting caught on the eyeball as
without getting caught on the eyeball as it swings we can see now that with the
it swings we can see now that with the
it swings we can see now that with the eye bolt in place no matter what angle I
eye bolt in place no matter what angle I
eye bolt in place no matter what angle I pull this string at it’s always pulling
pull this string at it’s always pulling
pull this string at it’s always pulling down on the back of the trebuchet arm
down on the back of the trebuchet arm
down on the back of the trebuchet arm the same way I can pull it straight up
the same way I can pull it straight up
the same way I can pull it straight up and it still pulls straight down so I
and it still pulls straight down so I
and it still pulls straight down so I pull it out in the direction that the
pull it out in the direction that the
pull it out in the direction that the rat trap will be we have a great angle
rat trap will be we have a great angle
rat trap will be we have a great angle pulling the same direction as gravity so
pulling the same direction as gravity so
pulling the same direction as gravity so I’m hoping this will work pretty well

think if we fire it indoors we’ll just end up breaking stuff but
we’ll just end up breaking stuff but
we’ll just end up breaking stuff but we’ll see if we can get it to fire even
we’ll see if we can get it to fire even
we’ll see if we can get it to fire even though there’s no projectile in it now
though there’s no projectile in it now
though there’s no projectile in it now to set it off I have some popsicle
to set it off I have some popsicle
to set it off I have some popsicle sticks wrapped in some paper towel

it might be a little too powerful and
it might be a little too powerful and need some reinforcement we’ve got some
need some reinforcement we’ve got some
need some reinforcement we’ve got some much thicker stronger string I’m gonna
much thicker stronger string I’m gonna
much thicker stronger string I’m gonna try tying that in the same way attaching

back let’s try launching it again and
back let’s try launching it again and see if we can get it to not break apart
see if we can get it to not break apart
see if we can get it to not break apart this time there’s still no projectile in
this time there’s still no projectile in

I didn’t keep a better eye on it we had
I didn’t keep a better eye on it we had two shots where we launched them out of
two shots where we launched them out of
two shots where we launched them out of the trebuchet but we couldn’t really see
the trebuchet but we couldn’t really see
the trebuchet but we couldn’t really see where they went they launched off so
where they went they launched off so
where they went they launched off so quickly that we lost track of them and
quickly that we lost track of them and
quickly that we lost track of them and even looking at the high-speed footage
even looking at the high-speed footage
even looking at the high-speed footage of the camera we couldn’t really see
of the camera we couldn’t really see
of the camera we couldn’t really see where they were going because they left
where they were going because they left
where they were going because they left the frame pretty fast
the frame pretty fast
the frame pretty fast so I actually had my cameraman stand
so I actually had my cameraman stand
so I actually had my cameraman stand behind the trebuchet just to watch and
behind the trebuchet just to watch and
behind the trebuchet just to watch and pay attention to where the shot was
pay attention to where the shot was
pay attention to where the shot was going because we couldn’t find it
going because we couldn’t find it
going because we couldn’t find it and we finally managed to track where
and we finally managed to track where
and we finally managed to track where one launched after we launched it and I
one launched after we launched it and I
one launched after we launched it and I was amazed at where it ended up how far
was amazed at where it ended up how far
was amazed at where it ended up how far back is that thing there it is
back is that thing there it is
back is that thing there it is there we go this is where it landed so
there we go this is where it landed so
there we go this is where it landed so the trebuchet way over there and so it’s
the trebuchet way over there and so it’s
the trebuchet way over there and so it’s possible that our first couple shots
possible that our first couple shots
possible that our first couple shots went about as far as well and they just
went about as far as well and they just
went about as far as well and they just have blended it into the grass so far
have blended it into the grass so far
have blended it into the grass so far but I am amazed I’m amazed at how far
but I am amazed I’m amazed at how far
but I am amazed I’m amazed at how far that went like I thought we’d get maybe
that went like I thought we’d get maybe
that went like I thought we’d get maybe two or three times as far and well maybe
two or three times as far and well maybe
two or three times as far and well maybe that is two or three times as far it
that is two or three times as far it
that is two or three times as far it just seems like a lot if our first shot
just seems like a lot if our first shot
just seems like a lot if our first shot was 20 feet then this is now I have to
was 20 feet then this is now I have to
was 20 feet then this is now I have to measure it’s gonna take a while because
measure it’s gonna take a while because
measure it’s gonna take a while because it’s a long ways but see how close one
it’s a long ways but see how close one
it’s a long ways but see how close one almost 73 feet that’s pretty great 3 2 1
this thing is working great with the
this thing is working great with the counterweight on it we get shots 20 to
counterweight on it we get shots 20 to
counterweight on it we get shots 20 to 25 feet away with the rat trap on it we
25 feet away with the rat trap on it we
25 feet away with the rat trap on it we are getting shots up to 80 feet away
are getting shots up to 80 feet away
are getting shots up to 80 feet away that’s pretty nuts this is certainly the
