I'll see you guys in a minute!
You're gonna have to crouch down more.
Ah there you go!
Alright alright.
Oh my gosh this is terrifying.
Hahaha!
Hey guys we're Evan and Katelyn!
And I'm Bob at I Like to Make Stuff!
And today we're making a leather ping pong
net with adjustable 3D printed brackets.
I wanted a ping pong table that had some storage
built underneath it and some LEDs embedded
in it, and that just could not handle a regular
old net, so these guys helped out.
To see that build video head over to Bob's
channel, and if you don't have a ping pong
table or a Bob to build you one, then you
can take these same brackets and put them
on any table, turning them into a ping pong
table.
Let's go!
Oh!
I hit it!
Look how much taller I am than this guy.
haha this net is gonna be made of leather
3d printed parts and and some hardware.
were gonna focus on the leather first but
before we do the full thing were gonna do
some tests so that we don't burn bob's house
down.
So were gonna be cutting this on the laser
which we have never used.
the thing that were testing is that the Barge
cement doesn't catch on fire that's the big
unknown.
because our design required the holes in the
net to be perfectly lined up, we wanted to
be able to fold our leather in half with the
rubber cement and then cut through both layers
at the same time.
the inaugural first cut.
go for it we started with old rubber cement
but quickly realized we would need a new can.
So here is the old stuff that you can do that
with.
Haha, that doesn't seem right!
It's solid!!
AHH.
Don't know what I expected!
To use the adhesive we applied it to the two
surfaces that we wanted to bond, let it dry,
then pushed them together.
Ok, we're going to fold it over.
Don't mind this ugly part, that was the old
stuff.
Can I... can I hammer it?
Yeah that actually give it a good crease!
Hammer it again?
Bob's gonna be like "what are you guys hammering,
I thought you were just folding a piece of
leather?"
Leather sandwich.
Smells like contact cement.
So, we just need to let this dry for a couple
hours and then we can test it!
It's time!
Oh wait, we need to turn on the blower!
Ahh turn on the blower now!
Thank you!
Oh yeah it's going.
Those tiny flames are ok?
Smash the glass!
Bob, this wasn't expensive was it?
The etch is looking really good!
Yeah.
Can I poke it?
Oh it didn't go through!
Well, we'll test it again.
So success, and failure.
Success because it didn't catch on fire.
Failure because it did not cut through all
the way.
We can swap between speed and power, it's
just a balance of more passes with low power,
slower with higher power, or any combination.
So we're going to try and run it one more
time on a higher power.
But the etching worked well!
Yeah the etching worked great, that's awesome!
Ooh, get it get it!
Ahhh!
Moment of truth!
Take 2.
Oop, ahhh nooo dang it still didn't cut though.
Man!
Full full full power at 125 speed.
Ookay!
It definitely did not work.
Ahh dangit.
I thought this would be the easy part.
Hello there.
We're going to talk about net designs and
why ours didn't work.
Keep on going!
The first design relied on us cutting through
both layers of leather at the same time because
it had to be aligned perfectly, that didn't
work, so Bob came up with an idea that allowed
us more wiggle room and didn't have to be
aligned exactly.
So you end up like this and they end up crossing,
making a pattern.
Is that right?
We could maybe do a block of diagonal and
then like a break and then a block of diagonals
and then a break every 12 inches or so.
So then we would not have to align them perfectly.
Or we could just fill the net with crazy faces.
Not a bad idea.
That is true, we do have that as a vector!
So that is what we've designed here.
We tested the design on another scrap piece
to see if it would work.
It should theoretically line up.
One thing to think about here is that if we
cover the entire back surface with barge this
will be covered in barge.
It will kinda look like a dog slobbered on
it and it dried.
Haha, is that the look you want?
I mean it will look gross at first but then
after that it will probably be fine.
We could test that too, on a little scrap
piece and see if like.
Test it on this one.
Yeah.
Oh, this has been sinking.
Next we moved on to printing the clamps that
will hold the net on to the table.
Ready to go?What will I be saying?
We need to say like...
This is future Evan here with a working clamp.
I'm going to explain how it works so that
the stuff we're doing in the coming scene
makes sense.
That was good!
This is what we're going to be making throughout
this montage of videos that hopefully will
make sense.
We have the main body right here we have the
support right here we have this plate here
which swivels and applies clamping force to
the ping pong table and you slide your net
down right here and put this little cap on
top and then you tighten this nut right here
to hold it in place.
If you need to tension your net you can pull
it back a little bit, tension it, tighten
the bottom thumb nut and it's good to go!
OMG you're so smart you thought of everything.
I think you're cute!
We used the MOARstruder to print most of our
parts.
It extrudes a lot more filament than the usual
print head so it's faster and stronger.
Nice.
This is weighty!
I'm not sure if it's fully beefy.
But its definitely weighty.
Supports right here, I kinda just want to
do all of them but I also want to get a good
video of it.
Is this a good video time?
Mmm probably not.
So we want to have a thread in here so that
we can lock this against the table so we're
going to embed this brass threaded insert
and its heat set so I have this soldering
iron and I'm very carefully going to put this
on and when you insert this in it starts melting
everything and you see this part right here
that has knurl?
When it cools, the plastic hardens around
the knurl and it really locks it in and prevents
it from rotating or anything.
We've not done this before.
I've done this before.
Oh, you've done this before?
Yeah, for work!
The heck.
The heck, I did this without you!
You did it without me!
Whoa!
There it goes!
It's sinking!
Thats so cool!
And then, ha, oh my gosh that's so cool!
We test fit our hex bolt into it and it works!
So this is the main body of our net clamp
but we're going to reinforce it with some
metal rod.
We probably don't have to because the MOARstruder
is pretty beefy but just to be safe... and
to cut some metal.
I just realized that when I was measuring
how much metal we needed I measured for one.
We have this much left over.
How do you feel about a sub par product Bob?
Some sweet moves!
I don't know.
Whether or not it's going to break?
Yeah.
3D prints are often not quite as accurate
as your model so the holes for our metal rod
were a little too tight.
We first tried drilling them out but the drill
was not long enough to reach the middle.
Yeah thats going to split.
It's going to split in the middle?
It didn't drill all the way thought.
I wanna try it.
It's totally going to split.
Oh no, pop.
You're going to have to break it.
Go ahead and smack it though and it's going
to split the part apart.
Oh wow.
Or did we is it in there now?
It's in there, there is some slight layer
separation right here.
There is a slight bulge.
That's actually not too bad though.
It's so heavy!
I know.
You could leave a gap in it.
Oh right there.
In that section.
Because this can reach.
So there would just be a slight gap right
there.
OR we could drill it and then in the center
where it's hidden we could have the hole be
bigger.
Yeah I mean really the hole only needs to
be tight on the outside yeah just to hold
it in for a press fit yeah.
I think that might do it.
We tried test fitting some more pieces but...
nope ooh boy that's quite broken.
So we have test fit all of these parts and
learned a lot and we're going to have to reprint
almost every single one of them.
These two were too snug of a fir because the
MOARstruder puts out so much filament it messes
with the tight tolerances I had.
This guy right here, I'm going to make him
a little bit longer just in case over time
the net sags, it can be stretched out a little
bit more and pulled nice and taut.
This guy right here I just messed up the height.
I just made it the wrong height.
I have no excuses!
But other than that I mean this guy is good.
We got our new pieces printing and turned
our attention back to the leather.
Ready?
First up was cutting it into a long rectangle
that was twice the height we needed for the
net.
Yayy great job ooo ooo.
So here is the piece of leather and we're
going to have one two three patterns cut right?
Yup.
So we're going to cut this, move it in, cut
that.
If we use painters tape around this we align
the laser with that box, it should cut right
where we want.
Ooky dooky so be very careful because this
tape is not the stickiest.
Ahhh there is a tripod in the way.
Ok so you may be wondering how we're going
to fit this into the glowforge.
We set up all these registration marks and
we're going to use those to feed it through
and do one block of pattern at a time.
You ready for this jelly?
I'm going to re-straighten this a bit but
that's ok.
Hey.
Bleeeh.
We made some wood guides to keep the leather
straight because if we messed up these cuts,
we'd be like: well i guess we're making a
net out of wood.
we've got EVA foam, we've got saran wrap.
saran wrap net! now lets load up the design
file and cross our fingers ok you ready it's
button pushing time.
yeah push the button! you ready?
do it!
oh ventilation! ventilation! run! let's see
how well this did.
nice! like little pieces of bacon.
bacon strips bacon strips lets um scooch it
back and do another.
this board right here this is gonna help us
feed this through k i've got a hold on the
leather alright i think we're good right here
alright we are ready for round 
this is it last piece nice it's gonna be a
real net do we wanna do a preview of the fold?
no, it's not time.
goodnight hahaha. one, two, first we removed
all the tape from the leather.
it seems like sometimes they're playing like
a stomping game all children their entire
lives are playing a stomping game the tape
left the leather looking a little rustic leather
was taken from indiana jones journal so authentic
but luckily we could rub the marks away oooooo
maybe if we kind of pre-crease it that will
will help a little bit it was kind of nerve
wracking knowing we had one shot to get this
glue up right i just don't wanna like i know
get to a point and be like oh no ahhh scrap
it we're going back to saran wrap net just
adds a little bit of character character,
that's what we were going for with our precision
laser cutting haha it's like a marketing term
when the machine didn't work.
built in character generator! yeah those look
really cool well we kinda have like a crease
which should give us like a starting point.
flip.
shall we barge let's barge hahaha want me
to do it yes engage nervous laughter mode
oooo it's like cheese i don't know what kind
of cheese booger cheese yeah I think like
sinus infection a thin coat of boogers look
at you getting fancy! oh jeez oh no katelyn
get that fix that oh jeez oh cheesus! i have
minutes worth of experience doing this.
minutes! we're pretty well covered yeah I
think so too oh my gosh boogers in your hair
ahh hahaha now we wait two coats we were thinking
about it so we were testing this piece right
here so go ahead and pull that apart errrr
yeah yeah you're good and I already ripped
that piece no you didn't I totally ripped
this I loosened it for you yeah so I think
we should be ok we did hammer that one pretty
well so i'll start in the center we can kind
of like hold it in an almost touching state
here and there ok it has begun ahh this is
going ok hahaha everything's worked so far
ooo ooo look at this it's like we knew what
we were doing can you get that spot right
there that that little little oh right here
yeah that looks really cool i know it looks
awesome that was way more not bad than i feared
i've been stressing about this cause it's
one piece of leather that little roller is
nice heh heh heh heh ahhh this is awesome
let's try this cool beans hammer ooo it is
getting flatter yeah look at that i feel like
a leather smith that is a nice edge 
with our net drying we went to help Bob with
the ping pong table good job Bob you have
to go check out his video the table is awesome
and has built in storage, LEDs and it's really
fancy because it's all made of wood.
we had so much fun working on it together
and we'll have a link below so you can check
it out does Bob always make you do the dirty
work?
heh heh heh he offered.
so smooth.
our new prints had a space in the middle of
the long run where we needed to drill our
clearance for our metal rods. we didn't try
to mess with the inner diameter because it
was better for it to be a little bit small
than a little bit too big.
ah yay oh jeez that is rigid with a capital
R oh it's a face look nice this is going really
well we also printed larger thumb nuts for
easier clamp tightening.
yeah nice yay next we cut the threaded rod
for the vertical post when it's first cut
the threads get all messed up but grinding
down the edge makes them usable again ah still
too tight this looks like a thing looks like
a thing oh we need the thing ok so the thing
is the new plate and spin nut we printed,
the piece that pushes against the table when
clamping that's quite broken the one we broke
earlier seems like it really doesn't wanna
go in there lets see if we can persuade it
ooo i was too hopeful ooo aww come out we
had already tried printing like three of these
so it was time to try a different approach
so i found a way to easily hey quiet down
hahaha I just realized too that my idea won't
work this is too fat oh dang it haha wait
wait there's another bit there's another bit
meow meow meow meow... let's see i think that
might be it don't wanna jinx it but i feel
decent about this oh boy ooo it sounds crunchy
ooo it works thank goodness, this little guy
has been a little bit of a pain in the butt.
so now we put this guy right here thread this
through here yay awesome so that raises up
and clamps onto things pretend this is the
side of a ping pong table yeah if that was
a ping pong table that would totally be clamped
onto it hahaha it looks great oh wow this
is actually bob look try pulling the 3d print
off wow i know it's pretty good it's pretty
good that's awesome so it is friday the fifth
day of project making things are going pretty
well we're about to reveal our net hopefully
everything turns out good cause we only have
one piece of leather and if it doesn't we
don't really have a project so cool feels
pretty strong still smells like barge still
smells like barge it's not sticky anymore
it's not sticky but it's still kind of like
it like boogers up oh Bob's looks really good
the Booger Master that's what they called
me in high school yeah it goes away cool so
the Barge dried a little bit shiny so we're
just gonna scuff it up with a screwdriver
that actually looks really good haha i know
right cool ok we'll get started on the next
cuts good luck with the LEDs we waited til
the ping pong table was ready to cut our net
to its final dimensions alright i'm not sure
if i'm in frame you're not we are going to
figure out where we need to cut this ok i
have a little over an inch right here the
tension on my fingers so we measured the marks
that we made and it's sixty nine inches but
when you measure the distance between these
posts it's seventy and a half so that's an
inch and a half stretch so that's why we measured
it physically instead of just doing it theoretically.
see if I got it in one go.
now we'll get the long one dancing in the
streets such good dancing ok so just so that
we cut this completely straight we're gonna
measure up 5 inches and then we will mark
a line and then we'll cut it with this.
quick thanks to our patreon supporters! if
you wanna check out our patreon perks like
the full hour long rough cut of this video
go to patreon dot com slash evan and katelyn.
thanks! ooo alright that looks good we cut
the net height down to the five and a half
inches we had marked 
we noticed the corners hit the post so we
snipped em down next we'll make a leather
loop on each side to attach the net to the
posts we looped around some scrap leather
to get the right size wow it looks really
good ultimately we're gonna hand stitch the
leather but we wanted to reinforce it with
some more barge mark a line mark a line right
there and then you put the tape on blue tape
got the blues we're running low on time so
the coats they will be light ooo that's pretty
ok yeah that will work i just think you're
cute i think you're the cutest well i can't
argue with you when you use that voice you
got booger strings thanks for getting my booger
strings i'm always doing booger checks for
you cause i can see up your nose we peeled
off the tape before the glue got too dry after
30 minutes it was basically dry enough to
clamp together.
it's like a leather sandwich which is kind
of like burger which is a weird thing to say
feels nice lets see if it fits it should it's
quite snug snug is good is that one good too
this one's good too next was another first
for us.
hand stitching leather having a little leather
poking device thing helped a lot first we
just used it to mark the places we wanted
our stitching so glad you stayed miked so
glad let's hammer this it's hammer time then
we hammered it through the leather to make
the holes it helps to have some scrap wood
to hammer into 
a lesson in cross stitching leather we want
this to be crisscrosses but on both sides
so what we're gonna do is go across the top
and then skip every other one doing diagonally
all the way down one the bottom and then do
it all the way back up the top that's how
you get x's on both sides.
yay this is literally the final step y'all
we used a wax coated string cord string cord
that we got at Tandy leather and it felt really
sturdy hey bob can we borrow your thumbs real
quick can we borrow your thumbs real quick?
two one go thank you first test fit is go
nice move back yeah hahaha am i in it? somebody
get me some coffee please?
hahaha don't mess up our net bob it's too
short now there's tension that we can apply
and now tighten the bottom nut uh oh that
piece snap off yeah that little piece we'll
be right back ping pong drama ping pong drama
should be good enough take two alright should
we play a game lets play some ping pong trying
to get fancy! swing and a miss! take you one
on two c'mon ok ok I'll see you guys in a
minute thank you guys for watching hope you
like this video and if you haven't subscribed
to bob's channel yet what are you doing we've
gotten so much inspiration from him and he
really helped us figure out what we wanted
to do on YouTube and we're gonna make him
do the aftershow with is which is where we
talk about all the behind the scenes stuff
that didn't make it into this video so if
you wanna check that out go to patreon dot
com slash evan and katelyn alright guys thanks
for watching bye hahaha berp a derp a derp
a derr ahh ah ow oh no did you turn your mic
on i did wow i'm not filming you are filming
i need a picture you're filming! decent don't
do that it's a little bit touching in the
middle shh no one was gonna say that flatten
myself like a hamster alrighty we are normal
we are weird just set it here there's there's
boogers can we make you a laser cut sign that
says booger master it's kinda just like going
in cut it into leather and cover it with barge
hahaha that's super gross
