a few months ago I built the cat food out of Lego and I've since taken it apart again but Kirk has
been plowing after it ever since so I've been experimenting with building a very simple one
out of wood so this contraption is just clamped together pieces of wood to see if the concept
work so I used that to come up with dimensions for sort of a design and I'm making that out
of some pre varnished plywood because I figure that will slide better with these caps I need to
slot down the middle of this piece of wood and I don't want any chip out so I'm pre scoring it
this is the trigger and it goes in this slot pivots on a pin on the front but haven't actually
given any thought higher I get that pin in there so I think I'll just cut a slot on the bottom
so I need to keep this from falling out on the bottom and I also need to push it up so that
this can catch the cap and I made this a little metal thing that goes on here which pushes right
there keeps it from falling out and that pops that up I just need to screw it on with some
very short screws now with the rubber band in place I can pull this and it latches onto here
except I need something to hold this caps down when it's back here until I push the trigger I
just made this fancy block to hold it down not just gonna work out where it needs to go I think
right about here I need a little bit of space behind it my rubber band yes anticipate the
kids will be playing a lot with this and I don't want them messing around with the spring mechanism
so I made this block that fits on here and that also props up this whole thing and angle so the
nice thing is this thing is easy enough to load I think the kids will be able to do it themselves
next step is building a handheld version of this cap sugar so this is the first time I'm
using a dado blade in years I don't like them very much but in this case I have enough parts
that it makes sense right now these slots are 21 millimeters wide I need them to be
33 millimeters wide I worked out I need an extra point to 3 inches on each side y inches because
my dial indicator is in inches so one two and point three there that's for any defense
now I'm gonna cut this slot in these pieces that's this slot and the nice thing about
making a whole bunch of these is it's worth the time to jig things up on my slot mortiser
the annoying part is takes a long time to set it up and the bits I'm cutting out of
plywood here are the triggers for a ton of these cap shooters that they're it's
pretty bad on some of them I printed out a few more of these templates and I actually
made this part a little bit thicker cuz that's awfully thin on some of them and
I'll be cutting that on top of this part here so there's gonna be less tear on the bottom
I can tear those slots but only filmed one next thing I'll drill the holes in here that's for
this thing to go in here and pivot on the next thing I'm making here is a little holder that goes
on top that holds the cap down until I pulled the trigger and I had some second class about whether
I'm cleaning that in the right position so I'm checking against the cap and making a very minor
adjustments I made those cap holders in pairs of two so I have a bigger piece to hold and later
I have them in Hana these little trapezoidal bits I'm cutting here are the extensions for
attaching the rubber band to and I'm sending all the edges on those Brown before I glue them on
I've glued three of those together like this but getting those two parts lined up at the
same time it's really hard because it tends to drift so I've been gluing them just by weighting
them down like that on one side only and then the other side that just prop it up on another
piece like that and then I can put this stuff on here and a weight I'm gluing on the grips
the same way because it's easier to line up that way I have to put the weight on the very edge
here so that it's over the center of the joint here this slot has a half depth extension on
this side I didn't show cutting that actually cut those freehand afterwards and that little
notch and the trigger fits in there and that keeps the keeps this from coming up too far
so that I can slide the cap over that without catching the end of it and nail goes in this
side here to hold that in place and a tie a rubber band to the trigger to pull it up
and now they're all assembled and varnished my Christmas presents for 2019 well pick him
up now you don't need all my fancy tools to make one of these I made this one with more
basic tools using a set of plans they'll have for sale and this one is actually modified to
shoot juice bottle caps I'll have a separate video about making that one
