Club demo: 28 May 2025
Report by: Kevin McFall
Kieran’s demo of a lidded spoon was a fun demo filled with spoonerisms and heckling encouraged. There was plenty of both!
The Spoon Bowl
Kieran started with a blank 50 x 55 and approx. 150mm long. For the demo this had been pre-prepared with a 20 x 50 piece cut out of it and a waste block of the same size glued in place. The piece cut out was then glued to another waste block for turning the lid, alignment of the grain needs to be considered here.
The piece that was to be the spoon was then marked out to get the centres. At the end with the waste glued on the centre is marked on the core piece ignoring the waste piece, the other end is marked to exclude the same area as the waste at the opposite end and then marked up.
With what was to be the spherical spoon end in the chuck, Kieran bought up the tailstock and rounded to a blank cylinder (at approx 1750rpm) and added a spigot at the tailstock end. The finished diameter of the cylinder is 47mm.
Removing the blank and mounting it in the chuck he turned a sphere for the outside of the spoon bowl.

This sphere can be mathematically calculated, but in this case, Kieran used Soren Berger designed sphere calliper which does these proportions for cutting away corners to get a rough sphere. Once these are done the rough sphere is then machined to a nice sphere by eye, although using a piece of pipe can assist by rubbing it on the rotating sphere to highlight high spots, and sanded this to a nice finish.

Kieran then bought up the tailstock and used a chuck cub (a pre-turned cylinder of wood with a semi spherical cutout at one end that goes between the sphere and the tailstock to prevent damage to the sphere while between centres) between the sphere and the tailstock.
Kieran then turned the handle with some beads at the spoon end and 3 lines darkened with wire to embellish the handle. This was then sanded and parted off.

This piece was then put into a larger chuck with the glued waste block section exposed and the handle protruding through the gap in the jaws.
A piece of cut cardboard tube with a slit in it was placed around the sphere to protect from jaw damage.

The waste block was then turned off and the bowl of the spoon hollowed out. It is noted that care should be taken to not catch your arm on the spinning handle whilst doing this part of the spoon, as it is moving rapidly in close proximity. Kieran also removed his watch for this.

When hollowing out ensure you leave room for the lip for the lid to lock into and then cut this lip. The inside was then sanded.
The Spoon Lid
The other block that had the piece cut out of the spoon blank and glued to the waste block was then put into the chuck with the glued spoon blank piece exposed.

Kieran turned the wood round, faced it off. He then measured the spoon and turned a tenon to fit and hollowed out the lid of the box, regularly stopping the lathe and testing the fit of the spoon to the lid.

Kieran then shaped the top and parted it off. The then made a jam chuck from the remaining waste block to complete the top of the lid. After the lid flew across the room some hot glue was used to help secure it on the jam chuck! This was checked regularly with the spoon to ensure the spherical shapes match as closely as possible.

Kieran did a great demo filled with useful information and completed with his entertaining and humorous style!
