Mark’s demonstration focused on the challenges of hollow forms with two interesting projects, firstly a Chinese water bucket and secondly an ingenious hollow form with narrow neck quickly made as two halves of a box glued together.
The water bucket was made from a piece of end grain ash with the corners knocked off on the band saw. Having turned to round with a spindle roughing gouge the base end was squared off with a parting tool and then again to form a spigot.

Finally the neck end was cleaned up with a skew and the bucket was ready for hollowing. As the bucket was no more than 5” deep it was OK to use a 10mm spindle gouge for the hollowing.
Top Tip 3 -
The inside of the hollow form was finished with a scraper.
The next step was the cutouts -
Top Tip 4 -
The bucket was now reverse mounted in the chuck using a jam chuck and router mat so that the base could be finished off using a spindle gouge and skew to create an indented base which was finally sanded smooth.
Scorching the whole bucket with a blow torch could be a hazardous procedure!
Top Tip 5 -
Having scorched once then a small wire brush (a suede brush) was used to rub out the grain and then the scorching and wire brush procedure repeated. Finally the presentation of the piece was completed by tying a number of thin black bamboo stalks together with annealed copper wire and the completed bucket mounted on an appropriate base e.g. wood or slate.
The second project was a hollow form box in oak …
Using a standard box method … block held in 4-
Mount the lid and hollow out, initially making a hole right through to form the vessel opening. Continue the hollow out up to the registration mark and then use a skew to create an almost parallel side (tapered inwards slightly) until the base fits snugly bearing in mind that the lid and base will eventually be glued together once the hollowing of both baser and lid has been completed.
Hollow out the base, fit the top and then finish the top opening. Use a fluted parting tool to create beads from top to bottom of the vessel. Having glued lid and base together mount the top in a jam chuck and shape the base slightly concave and job done, apart from finishes of course.
A very satisfying 30min project!
Once again, thanks to Mark for an enjoyable and informative evening.
