21st May – Greg Moreton

23 May, 2012

It’s been a few years since Greg last visited us and this was a welcome return.

He turned up with an enormous Vicmarc lathe and all his kit in a horse box towed by a Land Rover which seriously challenged the access to the institute.

The first demo was a round bottom bowl with double off centre hollows. The yew blank was mounted on a screw chuck to turn the outside. Greg is not a fan of long grind gouges, preferring more traditional grinds for bowl work. Long ground gouges were really designed for pull cuts along the grain for hollow forms and not for push cuts. Greg’s favourite tool is the 5/8” bowl gouge and he has several, ground at various angles. Steep angles like 60o are used for working deep inside a bowl in order to maintain a rubbing bevel when far from the rest. Working closer to the rest, Greg uses his little finger on the rest to stop the gouge kicking back on entering the work before the bevel can be brought into play.

The face was partly cut as well whilst mounted this way round, leaving a small raised area in the centre. Having sanded the outside, the bowl was removed and the raised centre roughly flattened with a power chisel. 2 centres were marked on the face and the bowl mounted in a jig to turn the hollows. The jig consisted of 2 wooden discs held together with long bolts. The rear disc had a spigot screwed on for chuck mounting and the front disc had a hole through which the hollows could be turned. The bowl was mounted offset with the smaller hollow centre on the axis and this was scooped out with a bowl gouge. Remounting with the larger hollow centred allowed this to be turned. Careful power sanding is needed to maintain the sharp line between the 2 hollows.

The second demo was a bud vase with an offset flared rim with a natural edge. Starting with the log between centres but offset, the stem was started below the rim for balance but left thick at this stage for support. A spigot was turned at the base to get into a chuck ASAP. The flared rim was turned carefully on both sides. Firm tool work is needed since there is no chance of supporting the gouge via the bevel. A hole was drilled at slow speed with a gouge to the required depth. The stem was turned in stages, working towards the base. It is not possible to go back to re-turn the rim or top of stem so it has to be finished as you go.

At this point we were given a choice of a third quick demo or a critique of the gallery. The project was chosen. This was Greg’s method of turning a sphere. Starting with a square section blank Greg turned a cylinder between centres. Marking the length equal to the diameter, the ends were rounded over. It was then parted off and re-mounted at about 45o between cups on the drive and tail centres. The shadow outline indicating where it wasn’t round was turned away. This was repeated with the sphere at different angles until an acceptable sphere was obtained, finishing by sanding. This is one of the few occasions when sanding is used for shaping.

We had been treated to a very full entertaining evening. It was a pity that time did not allow a critique since the table was full of really well turned items. They are all featured on the website.
