From Spiky Australian Burr to finished winged bowl
by Trevor Cocks

First find the balance point of the burr by balancing it on the top of a section of ½” dowel. Then hold the burr in place & mark around the dowel with a pencil.
Burr mounted on faceplate.  My lathe is a Myford ML8 with a maximum swing over the bed of 7 ½” Dia.  Therefore all work on this bowl will be on the outboard side of the headstock.
Flat created on the burr, size and position of re-chucking spigot marked with pencil.

The completed spigot. This measures 37 x 4mm (1 ½” x 5/32”) deep with a slight dovetail to suit my Axminster  chucks O’Donnell spigot jaws. Base of bowl and underside of wings turned ready for finish sanding. Ensure sufficient material is left to form the top side of the wing  and the top rim of the bowl which will be used to hold the bowl while turning off the base re-chucking spigot. Applying a coat of Danish oil to the base.

Bowl re-chucked in Axminster 38mm O’donnell jaws … …..  ready for work to start on shaping the top side of the wing and the inside of the bowl Bowl is now mounted in wooden jaws which grip on the  4 ¾” x 1/8”  lip of the bowl.  ¼” Bowl gouge is then used to remove the re-chucking spigot, leaving a concave base so the bowl sits flat.

Spigot removed and base finish sanded down  to 400 grit before applying a coat of friction polish. Due to the spiky edge of the burr it is much safer to finish polishing the top  and underside of the wings with a polishing mop mounted in a Dremel. Finished bowl is 210mm at it’s widest point and stands 40mm high.
