At the November meeting Joe Laird showed us
how to create two square bowls using the technique of turning on two separate planes.
Joe Laird turning 2 square
Starting with two blocks of Ash each
measuring 150 x 150 x75mm, he glued both blocks together using hot melt glue to form a cube, ensuring that
the end grain was orientated to face each other, and also to have level gluing surfaces.
Joe marked a circle on the end grain and
removed the corners with the band-saw. It is essential to turn the
end grain first, and this was achieved by mounting between a steb-centre at the drive end and a ring centre
in the tail stock. This was then turned to a cylinder using the roughing gouge coming in from the side
and above centre. The cylinder was refined using a skew chisel which was slightly rounded towards the
points – an interesting technique to minimize the dreaded dig in. Joe power sandied the
end grain which saves a lot of time, sandpaper and frustration. Accuracy of
measurements is essential throughout the project.
Change axis of cylinder and remount between
steb and ring centre. Mark the centre point of the cylinder all the way round and mark the finished size of
the bowls. Using the skew on its side, start cutting at centre point first, gradually working out to
each side of the cylinder. While introducing the skew above centre remember that chisel contact will only be at
centre when starting to cut. Use the tool rest as a guide to maintain a straight edge. Holding the skew handle
tight against your hip will give maximum tool control. When the flats meet at
the centre – you are back to square shape.

With the outside of the bowls turned to
shape, the glue joint was then prized apart. A bowl cradle jig was
constructed from two half circles of flat assembled at right angles to each other with a face plate fitted to
the back of the jig for fixing to the chuck. The first bowl was
glued into position in the jig and the ring centre in the tail stock was engaged as a safety
precaution. Clean the face and remove the steb and ring holding marks by reducing the dept of the
bowl by about 10mm, or alternately the top edge can be coved, or if the marks are not too severe they can be
carefully sanded out. Mark out the size of the bowl – leaving as much as possible in the centre for tail
stock ring support. Cut centre support to cone shape working towards the centre of the
bowl. Break out cone and clean centre of bowl with bowl gouge and
finish. Cut along the glue line with a Stanley knife to remove bowl from
jig. Finally, fit bowl into Button Jaws to create finished base. Repeat process for
second bowl. There you have it - a pair of twin bowls achieved in one project.
Joe concluded the last few minutes of the
demonstration by turning a Christmas Tree from a piece of 2”x2”x7” Sycamore. Mounted in the chuck it was turned to a cylinder and subsequently shaped to a point
at the tail stock end. Using the heel of the skew he cut uphill
against the grain creating a series of flares of shavings which remained attached to the tree
trunk. A bucket was shaped at the bottom of the tree, and green
spirit dye was applied to the attached shavings and tree trunk, while the bucket was decorated in red and
Thanks Joe for an entertaining and
informative evening, and also for presiding over the critique session which included the following
