Rachel's been using this manual grinder to grind the coffee but it's kind of
uncomfortable to hold like this for a long period so she even made these
gadgets to help hold it so now she's threatening to buy a fancy coffee
grinder and I'm going "wait wait wait I'm sure I can put a motor on it".
specifically this one and this motor runs at about the right speed and after
I flipped the armature around it even runs in the right direction the
challenge is how to couple it onto here my first thought was to just have an arm
sticking off with this one to crank this around but having this thing flailing
around like that might be more dangerous than it needs to be then the next
thought was to make something that goes on here that has an oblong hole like
that and really the ideal shape for that would be something like this which is
already part of this now this needs to engage with this thing here to fix the
fine adjustment but I could still engage the top of this thing just by engaging
the shoulders of these arms
and here's the part except I forgot to take into account this knob here so it
doesn't actually fit so I mean it the whole part again a little bit taller
with room for the knob tight fit on there for now I'm just attaching it on
there with a piece of copper wire so if things go wrong that'll just shear off
so this goes on here the grinder goes in here I cut down those brackets a bit
they're going to go here and then somehow the motor gets mounted on top of
it all I think these two little brackets will note that motor it just about the
right height okay I got it wired up with the capacitor and just some goat bleats
because I'm not sure this will work so let's plug it in Oh excellent
well that's a very finely ground it turns out that coffee was ground to fine
and I also need to move everything up a bit so that this slides in under there
and I cut this bracket up to make this part here which will hold up the motor a
little bit better than these little angle brackets I put a power cord on
there and the power switch and the wiring is buried in the back here I
didn't fill that because that's just bait for the safety trolls well there it
is put together now if we end up using it it'll certainly be a conversation
piece
Oh
