He's back, and we're using him for spare parts.
Oh my God.
What are we making? A power eraser that you can erase industrial quantities of mistakes with.
Now to give you a tour of the CAD model, I present Mr. Bone.
Hey kids, do you wanna buy some CAD models?
This is the power eraser!
Here we have the eraser and here is the power.
Yeah, it's - it's the Jigsaw motor on the bottom
we're going to strap an eraser to it and then let's cut all these pieces.
So it's Laser...
TIME!!!
Nice... execute
I'm not sure what my confidence level is on this thing fitting together.
Should we try to salvage the zip ties? Yes, because I'm cheap.
Should we turn that nasty chime off?
This is not a good use of my time.
Oh.
This needs to fit over that.
Laser Bandsaw is definitely the right way to do this, and we need a little bit more aggressive here,
but other than that looks pretty sweet to me. And it fits.
Looks nice.
God, this is going to be a pain in the butt isn't it?
And thennn...
And then..
and then and then and then and then
There we go.
And this will fit like
It's not like perfect and this definitely digs in your fingers a little bit.
Might need more hands so that I can-
No that's the wrong way to do more hands.
Okay, so then this is here.
Wow, this looks great. Oh my God. Did this actually come together this quickly?
Did I do something wrong? Stuff always goes wrong.
I really hope none of these wires disconnect and touch each other or we're going to have a spark show.
We haven't attached the eraser. I think where things are going to go wrong are when we attach the eraser.
So this has to be out, which is not so we've got to turn this on.
Probably should have clipped those on first because these...batteries are scary!
Yeah, I think it struggled quite a bit last time trying to do this little first piece
and I'm not going to let it get to me again.
Oh
Meh
Yes. Yes!
If we do it just all the way around then it hits this...
Uh oh.
Is that all the way down?
Remember last time when it was like knocking against it and it was like-
It hits a little bit. I can feel, yeah, you can't really...
I should have seen that coming.
This thing is going to break again probably because its cheap plywood
but it fits like really well in this groove. We got to find something of like the same thickness
Tada! Okay, sweet! Delrin!
*snap* Uuh...
Oh my God.
Hello? Why would I make cookies? I mean I like cookies. I can't believe this phone call is actually happening.
No! There's washers everywhere.
It's hard to get in but it just seems to comes out really easily.
Having to shove the eraser back in every couple of seconds seems to be the bottleneck here.
That fell out the bottom.
The only thing I can see being a problem with this product is having to tape all your like
homework and other assignments down we need to erase the whole page
but it's, I guess, a minor inconvenience for this sort of unprecedented undo power.
I'm tempted to just Superglue this thing in here
but then the problem is, if you- if you- when you run out,
which inevitably would happen within you know, I'm thinking 30 seconds to a minute,
you'd have to like undo, or put a whole new cartridge.
Well, maybe like a subscription you have to buy new- new rubber.
And this seems to do a pretty decent job like I bet you if I had to erase it by hand you're taking me somewhere
between like 30 minutes to an hour and this thing has cut that down into like five seconds
This just makes me feel like a man.
What should we erase now? For our final test, we're going to have a race.
On your marks, get set, go!
