The way the machine is supposed to work is I've got a magazine
full of dominoes and the slider that goes like this
and then this travels continuously while this pushes
the dominoes out one at a time.
So now I need a way for this thing to move
when this thing is turning, and this is where it got complicated
So I figured I'd use some ball bearings like this for the wheels
and put those into slots here.
And then have the rubber band go around the shaft here
and around this bearing here and then just have that go around
a couple of rollers, except that rubber band keeps drifting
to the side on here so I ended up having to actually
put these rollers at a funny angle, so it barely works.
And now let me just attach this here,
and then this part goes on here, like so.
And let's see. Now with this turning like this,
that causes the rubber band to drive the bearing down here
and that should drive this thing forward slowly.
Now I want to have a second drive wheel right here,
and I figured all I have to do is just copy this thing here
but I'm a little bit tight on space right there.
This block fits in here. And then the rollers
go in here in this hole. I just have to force that nail
on there.
That still doesn't quite work right.
I need this to tilt a little bit more.
Oh that's working pretty good.
So these two blocks let the nail spin on its pointy ends
and I mounted the motor here, and I added a third wheel
for it to ride on, so let's see how this goes.
So the machine produces about a one point four centimeter
spacing but I think ideal would be something like
a two and a half centimeter spacing.
And that means I need to make these drive wheels
turn a bit faster by somehow thickening up this shaft.
I work it out, I need to thicken it to about this thickness,
I can still make that out of wood.
Well, the spacing is about right I just need something to guide
those dominoes a bit better, and make this not flop so much.
This piece of wood will keep the dominoes all lined up as they
go along here and to hold that I actually have to reach over
the row of dominoes, so I made this part that arches over
everything so potentially I can stick the Dominoes
even in that side.
Now on this side getting that support over here got really
complicated which is why I have a really complicated part
that actually screws into the top of the bearing block
for one of its supports.
And this part also has this little hook here which keeps
this thing from falling out.
