I'm feeling brave.
Something gave way. Good old construction adhesive
The shelf will be good as new. Hang on, I want to get
one of my long-reach clamps. Oh yeah.
It's a homemade clamp around that.
You know what, I should get one of my long-reach clamps
to help you with that. How much weight can yours exert?
At least 200 pounds. Really.
This has to put in at least 202.
We should build a jig where we have the two clamps against
each other to see which one will break first, if you're willing
to sacrifice one of your clamps, we could do that.
Would you be willing to sacrifice one of yours?
I have no intention of sacrificing one of mine,
I know it I know it will win.
When you put it that way, as long as we're
breaking things today, Yeah. Yeah yeah.
The problem with these ones is that you keep turning
and turning and turning because these parts flex.
This doesn't. Yeah, like mine doesn't flex quite as much.
Cause I don't rely on, like this wimpy threaded rod
for the strength, I rely on wood.
But this is wood.
Yeah, but you got the weak, the steel is the weak part
on yours I think. No, I don't think so.
See, if that was just joined there with box joints,
that would have blown apart already.
Okay, we're gonna have to put this to the test.
I don't know much pressure that is, but
You have a bathroom scale? No.
If you're willing to drill a hole in the middle of that,
we'll just put a dial indicator on it.
Okay, I think we got this all right.
The controls aren't where they're supposed to be.
What? On your bandsaw it's like, "Where is the fucking knob?"
It's supposed to be here.
This is a real bandsaw. The switch is in the wrong place.
I want a tape measure. What are you doing?
I'm lost. This is my idea.
You're excluding me. Include me.
So, let's just put a little mark, like 12 inches from
either side of that, so we can consistently place the blocks.
The pivot points. Yeah, exactly.
I don't know if that's really that important, is it?
Well, if we're the same though, if we're the same for both,
Well, the thing is what might happen is we knock the pieces
from going from one to the next. I don't remember where it is.
I'll remember it too.
Apparatus. Got to be scientific.
So, now if we just set this to zero,
I'm not making any special claims for my clamp.
I know that is does what I want it to do.
So, John Heisz was just using one of his long-reach C-Clamps,
and I was making fun of it, that mine are stronger.
And, John Heisz had this cool idea for rigging up this
apparatus for testing the strength with it. So, we're just
gonna squeeze these together, and the dial indicator is gonna
show how much force, roughly, or some measure of force,
so we can compare which of these clamps can squeeze harder.
Okay, first up, my long-reach C-Clamp.
The clamp goes exactly in the middle.
This board, well we have these two things
exactly one foot on either side.
And, that's one revolution.
Two.
Coming up on, almost up on,
nearly there, three.
Three and a quarter. Okay, I think that's start
to fade a little bit. That's as far as I'm gonna go.
Three and a half. Unless John's goes further.
Three and a half, that's pretty impressive.
That hard maple one by four
deflected down, I would have to say 3/8th of an inch.
For sure, in the middle. Of course, the clamp itself
deflected more than that, because there's less wood on
the clamp than what we're squeezing here. Well, you know,
that's the thing with the homemade clamps, they're not,
you know, they're not made out of steel. Here we go,
now I've got a riser block, because mine is more open.
So, I'm gonna put that in place first.
This is gonna take a lot of cranking.
Cause mine flexes more readily. Um hm.
Have I made a revolution yet? One, you're at one.
I haven't reached two yet? Almost at two.
Really? Two now.
That's impressive, I might have to put mine on there again.
I mean, if you can do three and a half, I'll have to
crank mine up to four. How's it looking?
Two and a quarter.
Can't be moving very fast. No, no it isn't.
My clamp is flexing. Yeah.
Okay it's at two and a half. Getting to two and a half now.
I gotta keep going until either I reach three and a half,
or this thing breaks. Cause this is,
I'm all in on this one, man.
How are we looking? You're coming up on
two and three quarter.
Okay, I'm getting resistance now, significant resistance
It's probably just cause it's, kind of, getting bent.
That clamp is becoming Pushing it down.
seriously opening up, it's still at two and three quarter.
It hasn't moved? Well, it's moving a little bit
still. It's coming up on three.
I mean, the needles getting close to three
while you're cranking,but then it comes back.
See, what's happening here is this rod is going sideways again
See? Uh huh.
How is it? It's within ten thou of three.
Okay, it's at three now. You're at three.
I mean, it's going way past three right now while you're
cranking but again, like steady state because look.
I bet you, how's that look when I push up like that?
Oh yeah, that's going to 3 point If I straighten that up.
Three and a quarter. So...
It's the flexing of the rod, you can see the rod starting
to bend too, so this is really God damn strong here, man.
Oh, I'm hearing cracking. Yeah, you're down to three.
What? You're down to three now.
Yeah, it's, this is, when I was doing my joints and texting you,
you get to a certain point where the force stops going up.
Where the, you know, it's stuck. Has it changed?
Yeah, it's, let go.
You're at just over three. And, it's kind of,
drifting downwards Okay, let me push it.
Okay, it's three point four I can equal yours.
Have to crank it up to four now. Okay, maybe I'll just have to
crank mine up to four now. Will it make it?
I think so. I can still crank this although,
I can still crank this, although You're down to three again.
Yeah, it's starting to.
Yeah, it's just like the stretch on the threaded rod
I think is just stretching it a little too much.
Man, this crushing in the back here, you can see.
Yeah. Which is really something else.
So, you need a box joint.
Now, the whole frame of the...
Oh yeah, your threaded rod, look at that threaded rod,
it's just way bent. Yours is bigger.
So. And the depth.
I'm covering the camera.
Okay, see the pad is breaking.
Check it in the front there, and see what we're at.
I think that's three and a half. Either that or it's down to
two and a half, that's three and three quarters now.
Okay. So, the strength is there.
The problem is, is this rod
is too, too small.
Well yeah and this joint is just starting to yield right there,
in a big way. Yeah, but it's giving,
but it's not giving out, it's not breaking.
That's true, I think whereas my joints, when they go,
it's cause the wood snaps, so it’ll just go pop.
Yeah, it would like you wouldn't be able to take it this far.
This is flexed way out. I think has opened up,
maybe two and a half inches here. Yeah.
So, anyway.
It's kind of an apple and oranges type of test here.
Yeah, you're up against superior technology.
Hang on, let me see now if there's another clamp.
How about one of my red ones there, how do you think
they will fare? Probably better, cause you don't
have as much leverage.
Cause like this here would be, if this hadn't opened up
such an angle, this up here wouldn't have been as much
of a problem, like if it hadn't opened up such an angle
in the back, then the front would have been straight
and you wouldn't have had the problem there.
You can see this part gave way more than this one.
But, without the threaded rod, that wouldn't have worked at all
So, let's try this one.
Now, this is my least strong wooden clamp
other than that thing, because of the notches in the front.
You know what I should spend on that afterwards to calibrate it?
Cause I know I weigh about 150 odd pounds with clothes on.
Yeah? See how much it deflects?
Yeah. Where are we at?
One. Sorry, no that's two.
Well, something's starting to crack.
You're coming up on three. Yeah?
Whoa.
Yeah, see that's where they break, right on those notches.
Yeah, actually let me just try one of my clamps again.
I really didn't want to like Okay, at this point, it's just
showing off, okay, you know that? That's right.
And, the thing is I didn't want to risk breaking my clamp.
Just cause they're kind of a pain in the ass to make.
Which is why I didn't crank, and you know what,
I felt pretty safe at how far I cranked it.
Okay, coming up on one now.
Two.
Three.
Three and three quarters. Four.
Okay, that's enough. For a start, you went right past
before it started to fall back. Are you getting cracking?
I hear something popping. You might as well go,
cause at this point, it's done. Yeah, I think that's as much
You think so? Yeah, I can hear the cracking.
That top joint, I think, is starting to go.
Where are we at? It's making it to four and a half.
Okay, let's back off then.
You chicken, man. Yeah.
You chicken. I destroyed mine.
Two of them, actually. I destroyed this one.
Well, I went to four.
Actually, this is, yeah I think this joint is starting to
yield a little bit. Just behind this.
Go slow, that's one. Okay.
And a half.
That's one and three quarters. You could say it
it goes up to two when you bounce a little bit, so.
Let's try again.
One and three quarters. Okay.
So, I don't know if that's so, if that's a
a ratio, like you would directly multiply it by three,
or the number that it went up to. Right?
Mine went up to three and a half Yours went up to four and a half
almost, so would it be that much? Okay.
Would it be much. Assume it's greater in there.
I guess, you know, we didn't crack the wood at all.
Like this part. Okay, yeah.
A little over two and a half. You're a big guy.
I need to go on a diet. Shelf-breaking guy.
Anybody needs any shelves tested, I'm your man.
Yeah. I can do the jump test.
Kind of.
