There is nothing new about "inside - out " turning. It is a
clever method of producing interesting shapes for vases, urns,
Christmas tree decorations etc.
To start this work 4 square section pieces of timber are temporarily
joined e.g. by paper and glue (as in Fig.1). Draw out the shape of
the "windows" desired (as in Fig. 2) and then for the first turning
produce the reverse of this shape. Keep in mind that the minimum
diameter of the first turning should not be less than 60% of the
maximum diameter obtainable from the laminated block.
Separating the laminations, inverting the four pieces of timber and glueing them together permanently.
Re-turning the block to the desired outside shape This produces a hollow interior with four "windows".
Nice effects are obtained by painting or otherwise finishing the first turned shape prior to re - glueing permanently. This example produced a Christmas tree ornament. Give it a go. You will find it is good fun.
