hey this is Marie from DIY Montreal and today I'm going to show you how to make
a round cutting board and turn it into a Lazy Susan for this project I used three
types of hardwood cherry walnut and maple
since I'm working with raw lumber I started by cutting off the end before
cutting a few pieces to rough length slightly longer than the final
dimensions that I need I then ran the pieces on the jointer several times
until the bottom face was flat I could then flip that face up against the fence
to joint the edge after that I ran the boards a few times through my planer
until the top face was nice and flat too note that the boards don't all need to
be the same thickness at this point next I set my table saw to rip the boards
just wider than I want the final thickness of my cutting board to be
since the blanks will be flipped 90 degrees before glue up this way they'll
all be the same thickness I also wanted a few thinner strips of walnut so I
ripped down some of my blanks into thinner strips after deciding on a
pattern it's time for glue up since this board will be about 18 inches wide and
my planner is only 12 inches wide I'm going to do this glue up in two parts
that I'll assemble afterwards since this lazy susan is intended for food like
cheeses and charcuterie i made sure to use a food-safe glue like Titebond 2 or Titebond 3 that are both food safe and water resistant
after letting both parts dry overnight I could then run them through my planer a
few times on each side of the board one after the other so that both the top and
the bottom sides were flattened and both boards planed down to equal thickness
I can now assemble both parts but I noticed that the joint wasn't perfectly
straight so I did a quick pass on the jointer to flatten the inside edges I
can now assemble both parts by simply using some glue it's important to get
this joint flush so take your time here it helps to use small clamps along the
joint to help get both surfaces perfectly lined up I almost forgot but
you'll also need a second smaller board for the bottom part of the lazy susan
for this I simply planed two boards on face and glued them up
to cut out the circles I'm going to use my router with a homemade circle cutting
jig to make the jig I first need to remove the bottom plate from my router I
flipped the plate over onto a piece of thin plywood and marked out the four screw
holes and roughly Marked the center hole that I then drilled out using a large
Forstner bit then using a smaller Forstner bit i countersunk the four
screw holes using the depth stop on my drill press I could then drill all the
way through those holes using a bit slightly larger than the size of my
router screws after screwing the plywood onto the router and installing an up
spiral bit I traced out a centerline onto the board you can then make a pilot
hole for the desired size of the circles radius
I made my hole at 8 inches since I wanted a 16 inch wide circle next I
found the center of my board and made a very small pilot hole to use the jig I
simply put a small nail through both holes and tapped it in with a hammer I
first took a shallow pass going clockwise and progressively lowered my
bid after each full revolution you'll also want to vacuum up the sawdust
regularly to make it easier on your router ideally you should use a plunge
router for this but since I don't have one I manually plunge the bit each time
I lowered the bit and it worked out just fine eventually I made it all the way
through and was left with a nice round circle and this was probably the most
satisfying part of the project for me
I repeated the exact same process for the bottom circle simply adjusting the
size of the radius to make it smaller
okay so now I have both parts of my lazy susan that I'm going to assemble with
this turntable hardware but before I do that I have a little more prep work to
do like rounding over all the edges and of course a little sanding I started at
80 grit and progressively made my way all the way up to 220 grit now since the
board will be washed I'm going to water pop the board and let it dry in order to
raise the grain before sanding it once again with 220 grit there are different
ways to mount the hardware and I'll show you the one that I used my biggest
concern was to get the hardware perfectly centered I started by
measuring the distance between the holes and setting my compass to exactly half
that length then drew a circle using the center hole left behind by the circle
jig next I drew a line through the circle it doesn't matter where you draw
it as long as it passes through the center point I adjusted my compass to
make the opening wider then drew two arcs using the intersects as pivot
points I then drew another line through the circle using the spot where the arcs
intersect and the center point as guidelines both lines should now intersect
at 90 degrees and should line up with the holes in the hardware I used a
small bit to make pilot holes all the way through so the holes would be
transferred to the opposite side it was at this point that I realized my mistake
I should be using the tiny little holes for the bottom plate but luckily this
was an easy fix I measured the distance between those holes and adjusted my
compass to make the new markings after drilling the new pilot holes I flipped
the board over and countersunk the holes using a small Forstner bit and the
depth stop on my drill press the hole should be big enough for the screws that
come with the hardware kit I then repeated the whole process to mark the
holes for the top board and drilled some shallow pilot holes this time making
sure not to drill all the way through
before attaching the hardware I gave it one final sanding that vacuumed and
wiped off all of the sawdust I finished the board with some food
grade mineral oil applying a generous coat and letting it sit for 20 minutes I
repeated this process four times and then finished up by wiping off all the
excess oil I could now line up the hardware with the pre-drilled holes
starting with the top and screwing it down and then position the bottom piece
and screwed it down from above hey I hope you liked this video and if you did
