PROJECT Rocking hippo with moving jaw
62 The Woodworker & Good Woodworking October 2019 http://www.getwoodworking.com
This requires more power carving using the
Foredom fitted with a 2.5cm Saburrtooth
burr. This is why it is very important to have
a thick wall and bottom on the lower jaw as
these will now have to be removed slightly
to allow for the upper teeth to clear.
Once this is done, the two top teeth can
be installed. The head will need to be turned
upside down and the jaw closed so the teeth
are held exactly where they should be. Again,
lots of PVA is required, but I also recommend

using a bit of hot glue to make sure they are
held in place while the PVA dries around them.
THE HEAD PART 4 EARS/HANDLES
Now for the ears. Original Henry was to have
dowel handles behind his ears, but I found that
these were both in the ideal position and size
for handles.
Again, these are made from offcuts of 9×1
tulipwood, which I’ve used throughout the project
on the larger pieces. Using the ear template, cut
these out using a bandsaw (or coping saw). Then,
take a profile gauge and use this to find the curve
of the head where the ears will be positioned.
I strongly recommend using the gauge on both
sides rather than just assuming one side of the
head will be the same profile as the other. Also,
mark a line in the position where you place the
gauge on the head – you’ll need this later on.
Fitting the dowels
You can now mark the centre of the ear on the
side which will contact the head. Using an 8mm
bit, drill a hole into the first ear (photo 25). This
needs to be half the depth of your dowels (I used
8 × 40mm ones). Repeat for the other ear.
Carving the ears
Once this is done you can now carve the ear.
Using a Foredom or Dremel, as before, you need
to create an incline into the middle of the ear.
I went a little too deep and ended up breaking
through to the dowel hole, so go carefully around
where the hole has been bored for the dowel. The
back of the ears need to be curved on a shallow
curve and so, using the Foredom or a disc sander,
create this shape. I found dry fitting the dowel
handy for holding the ears while working on them.
Fitting the ears
Fitting the ears can be quite tricky, so using
the marks left on the head made when using
the profile gauge, find where the internal curve
best fits. Draw around the ear onto the head
and use this as your reference. Dry fit the dowel
and then add a blob of paint to the end. Line
up the ear outline with the ear and push the
dowel onto the surface of the head. It should
be roughly in the centre of the outline you just
drew. Next, using the same 8mm drill bit, drill
the corresponding dowel hole into the head.
Apply PVA to both the dowel and the contact
surface and repeat for the other side. Allow
to dry overnight.
Gaps may appear once the glue has dried,
in which case, run some filler around the bottom
of the ears where they meet the head.
