Tonight Roger Gilbert set up for 2 projects both based around bowls with a common theme of “propeller turning”. This is where the bowl is not round so you are “cutting air” for a large proportion of tile. It can be scary stuff so it is important to make sure your fingers etc are behind the tool rest and not in the line of the spinning wood.
The first bowl was a 3 cornered piece which is made by mounting an accurately cut cube of wood from point to point between centres (see photo).
The bottom was turned to finish and a chucking spigot created. The outside was sanded to a finish and the bowl rechucked on the spigot. The centre was then hollowed out but to make sure the wall thickness was accurate the toolrest was marked at the limit of your cut.
Sanding to a finish was done as power sanding and the points done with the lathe stopped. The bowl was then reversed onto a wooden former with the tailstock in place so that the spigot could be turned away. Roger’s hobby horse is that the base should always be finished so that the chucking point cannot be seen.
The second project was a natural edge Ash bowl where half a log was mounted on pin jaws in a chuck and the turning undertaken in the same was as for the first project. However, instead of a spigot for rechucking Roger used a recess on this bowl. The trick is to try to preserve the bark on the bowl but in this instance a large chunk of bark flew off. All was not lost, Roger suggested that the rest of the bark could be picked off and the natural edge scorched as a feature.
The 2 projects certainly produced interesting bowls that were a little out of the ordinary, and although not finished to Rogers usual standard looked amazing. This was another excellent demonstration with plenty of tips that we can employ on our turnings.
The March competition was a little disappointing in the turnout although the quality was as good as usual.
First was a lidded box by Mick Denton.
Second was a bowl by Henry Howard.
Third was a coloured platter by Gerald Hubbard
