Seven CNC Projects | How To

so a few months ago I got a 4×8 Laguna
CNC machine for the shop and since then I'd been having so much fun learning the
world of CNC learning its abilities and creating so many fun projects on it so
in this video I want to go over a little bit about my experience you know as a
new CNC operator and also seven different projects that I've created on
it the CNC shows up on a truck all
preassembled and wrapped up tight I didn't have to run a piece of equipment
to get it off the bed and man it was pretty intense watching my brand-new
machine just creeping slowly through the air to get to the port but it made it
there Safeway where I am packaged everything that I could before picking
it up once again and moving it to a corner of my shop now I've been using a
smaller iconic C&C for the past two years and while it's been great I want
to cut more than what the size will allow and that's what got me looking
into 4×8 I went with the Laguna Swift model this is a vacuum bed meaning you
can put the bed under suction and hold the material in place it's amazing to
have the capacity to throw an entire sheet of plywood or even 8-foot
dimensional lumber on the bed and then just let it cut now for those of you
concerned that my videos will be changing because of this addition
don't be I've still plan to make videos building things by hand like I always
have but when I come into a project that I either want to repeat or make a
template for or I have an idea but it would simply take way too long do by
hand that's when I'll turn to the machine the very first thing I decided
to make was a simple shop stool at the time the side of my shop was extremely
bare so I spent 20 minutes quickly modeling
up some things since I know Sketchup so well I pretty much do all of my modeling
there to start you could do it and one of the other modeling softwares though
or even in the– carves itself once the parts are as I want them I move and
rotate them so that they're on the same plane I choose a standard camera setting
to give me a direct top-down perspective to the parts then turn on parallel
projections under the camera setting in this setting instead of all the points
disappearing to one point on the horizon they're just nice and parallel in both
2d and 3d which gives you a nice flat image 2x
for now I can export it as a 2d graphic and choose the dot DXF file type next I
can open up that DX F and V color route the tool path for it and then cut it out and then just like that I have a very
simple but functional stool I really feel like C and C's are a modern-day
printer for thought it was exciting and crazy to me as I assembled and sat on
this first stool of mine that my pie was actually sitting on something tangible
that was only a mere thought half an hour before you can see I was so excited
I didn't even bother going to a ground to do the assembly work I just sat right
there on the bed the next tool was a much taller design to populate seating
over my woodworking shop I actually have a video showing how to do these without
a CNC if you're interested I made one of these by hand and then use the CNC to
thatch out the rest quickly then the third stool design I did when Christmas
rolled around there was gonna be 14 nieces and nephews at Christmas so I
could have stole for each child and also cut in their first initial onto the top
I did leave them raw but then I took a bunch of paint and everybody in old
clothes spent the afternoon in the yard with the kids
hoping to paint their stools it was a huge hit so if you have an event coming
up with some young'uns involved don't forget to download the debride DXF and
take a unique gift the next project is a plywood deadblow mallet because why not
I made this from quality Baltic birch and I only had half inch on hand so I
made multiples of the parts to stick together and build up the thickness of
the mallet oh and to show you how well the vacuum on the table works this is
Robert trying with all of his weight to move the sheet after laying it down and
turning the table on then you can also see how well the vacuum holds these
parts into place while they're being cut on these the holes were placed to act as
locators and keep these parts in line with one another as they were being
assembled then a pocket is cut in on the head so I have a void to place bb's in
and therefore making it a dead blow mallet I used type on original on the
different layers smush them together and then inserted a dowel into place
then I flipped it over and before attaching the other side the same way I
filled the pocket with bb's after setting those up in some Bessie quick
clamps to dry I did all of the final sanding and rounding over by hand as you
can see the mallets have gotten a little more complex with Tech's on both sides I
love this project so much I actually turned it into a branded product so if
you would like one there is a link for you down below project number three is a
bottle cap display in the shape of all 50 states it's a simple project where a
person can collect bottle caps from different beers and then have a way to
put them on display sometimes moving around a full sheet apply is difficult
but I found that by placing my stock of sheet Goods at the end of my CNC I can
simply slide a new sheet off the stack and onto the bed I also always check to
see if there is a slight cup in the material as I'm laying it down if so I
make sure to place it so that the cup is facing down since sheets typically have
a prettier front than back when I do this I make sure to take my designs and
reverse the image and V carve before cutting them out when doing something
like this job I first go through and cut all of those inside pockets throughout
the entire sheet then I come back and cut the profile also on jobs like this
even though I have a vacuum table I typically go ahead and add tabs to the
pieces because every hole like cut in allows air to escape therefore reducing
the effectiveness of the vacuum table oh and here on the Michigan you can see a
dark line running through the veneer on the backside this is just an example on
why reversing the image is helpful then here you can see a little bit better
that the holes have a unique shape to them they aren't actually perfectly
round by having a hole that has about four grab points it allows the caps to
have you know small variation in size but still be compressed into the state
they can simply be pushed in from the back by hand or the cap can be set down
and then the state can be pushed in over it
favorite zegen but good old Texas beer if you get one don't try to fill it up
in a single day unless you have a party then that's acceptable all right let's
talk about dust collection for a second and a few modifications I've done to
improve things so first off I'm using the Laguna Sea
flux dust collector which has this really awesome foot pedal to raise and
lower the collection canister it has three intake ports where originally I
only used one to run over to the spindle but I also wanted to use the collector
to clean off the bed after each project to do this I first added in a blast gate
to the spindle line then I added in another blast gate to the second port
where I bought an attached another four inch flex hose that I could then run
over to a Rockler shop-vac attachment I think Rockler specifically designed us
to clean up large area such as floors so it works perfectly to clean up the
entire C&C bed quickly I threw two hangers on the wall to store
it off the ground and so that it would be close to the work area now I can
close the vac off to the spindle and directl it only to this attachment and
then very quickly go over the entire bed before laying down a new sheet of
plywood this ensures that nothing is left behind to get under the material
which of course would throw off all my cuts all right now on the project for if
you've been around for a while then you might remember that my neighbors have a
lot of chickens in fact I felt them a massive chicken coop if you don't know
fresh farm eggs actually don't have to be refrigerated with that I made a
countertop egg holder to hold a full two dozen eggs
this one cracks hanging out because of how cute it is but better than just
being cute it's also functional after designing it and Sketchup then exporting
it to be carved I cut it out another tip for you on useful things to have around
the machine one is an extension cord I personally installed a cord reel that
can be pulled out to use and then retracted when done and even though you
can play with feed rates and rpms to get a nice cut I still run over the parts
quickly with my palm ara s before removing them then when I use tabs I use
my multi-tool now and just a tip whenever you're
placing your tabs pick spots on the part that are nice and flat so that you can
cut them off flush and then that cuts down post-production cleanup work on my
first batch of chickens it's a double sided design meant for sitting on the
countertop you can see that I did a slot design where after painting each tray it
could slip right around the body of the chicken and rest on two support pieces
my mom died when she saw them but said that she didn't have enough countertop
room for one and would need one that hung in a wall instead with that the one
sided egg holder was born since the slaughters out of the question you know
with it not having a back this one has a mortise and tenon design where the trays
fit very snugly and the slots on the body of the chicken since they are such
a good fit I made sure to tape them off before painting this one might be if you
can't tell I'm kind of in love with the egg holder let's switch off the wood for
just a second with project five my main goal with the CNC is to do more
production work behind the scenes either outside of my videos or in conjunction
with them an example of that is whenever I built a porch swing I made a video
building it by hand and showing viewers how but now I also sell templates for
people who are interested in speeding up the making process of their own swing I
personally think the making of these templates is so interesting I first lay
down a sheet of masonite but really any flat sheet will do then I lay on top of
that a sheet of styrene which is just a plastic material now the cool part is I
switch out the bit to something called a drag knife honestly it looks just like a
small exacto knife and when it runs the spindle doesn't turn like it does with
every other bed so instead of spinning and moving through the material to cut
it simply drags the blade along the tool path you take
and rotates the blades so that it's always in a cutting direction another
thing instead of cutting all the way through the material it just Pierce's it
so that whenever a full sheet is done you have to go through and bend slash
tear them out it carefully it's my deal because the material can stray and tear
in the wrong place it helps to first Bend the piece end along the cut and
then run your hand or nail along it to guide that tear this is a really great
material for making templates for projects that have a really unique shape
in them they can be set directly on a piece of material traced but then set
aside until they're needed again all right project number six and it's
back to wood making a growth chart ruler now everything I've cut up to this point
has been from sheet material when I was figuring out how to make these I decided
to make a jig to hold one by aids on the bed of my machine I started off with the
sheet of eighth inch plywood then cut down some 3/4 inch plywood scraps to
different links and attached it using tight bond to I would set up one by
eight in place use the square to make sure it is sitting there at a 90 and
then block it in on the other side with another scrap and total was able to fit
6 1 by 8 I transported the jig over to my CNC and lined it up on to the bed of
course dimensional lumber is not all exactly the same size so once in place I
used some wedge material to fill in the small gaps if they wiggled around making
sure to dress the board off to the left of the space I made sure to keep these
wedges short so they wouldn't interfere with a spindle or bit now I could start
the cut and watches all six boards would be cut at the same time I have a special
fondness for these rulers because I've made over a hundred of these by hand
when I first got into building these are actually what I made and sold to buy all
my first tools and materials for the first year of my projects so if you want
to make one yes of course the CNC makes it quicker but you can very easily do it
with the router as well in fact I have a video already showing you how to go that
route if you're interested ok last but not least because it's my personal
favorite project
seven is a variety of shop charts this started off by me making a fraction to
decimal conversion chart because getting into C and C you use decimals over
fractions and I got tired of always googling the conversions although a tip
for you if you work in V car if you only know the fraction you can type that in
then hit the equal key and it will convert it for you anyways I made this
chart to hang up by my CNC for quick reference and then it just snowballs and
I got carried away with making many others that would be hopeful or just fun
to have around my second one was a tap and drill size chart because even though
I have one hanging on my shop bridge it is freaking tiny you have to get this
close to it to read and I ain't got time for that but I do have a machine to
where I can make my own size chart that I can read at a glance for all of the
charts I'm using a wide variety of B bits and honestly there is a huge
learning curve on these because depending on the material and the size
of font determines what bit to use and how fast you can run it I started off
with a ton of blow out and how to do a lot of tests before diving into a new
chart to determine the speed and also the depth to get the best results
my favorite chart is more of a just a fun one it is a custom djenka scale if
you're not familiar with djenka is the hardness scale for woods the only
problem is most charts out there have woods that i've never heard of much less
use so I created my own list of species that I thought the average woodworker
would find useful now on the release you saw that I just spray-painted it and
then sanded off the overspray on these I tried a different method they do make
products that you can first paint your piece of material then mask it off
before cutting in your engravings I tried two different products while
prototyping these charts and honestly I didn't have much success with either so
instead of messing with it I would cut the charts spray paint the engravings
then using a foam roller come back and paint the background and this actually
came away with great-looking results then it just left the difficult job of
figuring out a good looking but legible color scheme I know I'll get a lot of
comments because of the big controversy around C and C's you know whether you
consider it real woodworking or not it is most definitely within the niche of
making and that is where my passion lies so I'm having a blast with it and
there's so much to learn and I cannot wait to explore it further now if you're
looking for an at-home resource to learn C and C then I recommend this book which
is CNC router essentials other than that I hope that you enjoyed this one I know
it is longer than normal but hopefully it came away with some good ideas I'll
see on my next project guys I want to say a big thank you to this video
sponsor which is molecule molecule is a complete reinvention of the air purifier
which replaces 70 year old technology imagine if your phone was the same as it
was back in the 1940s that's exactly when the technology you're using clean
your air was developed Biagio has introduced a breakthrough science back
by the EPA that is finally capable of destroying air pollutants out of
molecule level eliminating things like allergens airborne chemicals and
destroying pollutants a thousand times smaller than HEPA filters can even
capture I spend a lot of time in my shop where I'm constantly around sawdust
metal dust paints and finishes so I love how sleek and compact molecule is with a
handle on top so I can easily transport it to whatever station I'm currently
working at I've even been putting it in the bedroom at night where I can tell a
noticeable difference in the way I can breathe and therefore sleep molecules
technology has been personally effective and verified by science but most
importantly it's been tested out by real people I'm very excited to have molecule
as an addition to my shop if you would like to add one to yours or to your home
and I have a code that will give you $75 off your first order
