Another excellent demo from Mark with clear and interesting explanations at every stage -
Nick demonstrated 2 objects -
Two piece decorated vase …
The base was a block of builders pine and the stem from 180mm x 40mm spalted beech. The reason for making the vase out of two pieces was that the coloured base could be made out of cheap wood and there would be a lot of wastage if turned out of a single piece of expensive wood.
When selecting the builders pine try to avoid knots as these could affect the colouring -
Firstly the stem was turned to round and roughly shaped and a spigot created to fit into the base. A 10mm hole was then drilled from the opposite end to the spigot so that if the drill went off line slightly this wouldn’t be seen as it would be hidden in the spigot.
Top Tip 1 -
The base was turned to round and then a hole for the stem spigot made using a forstner bit. The base was roughly shaped noting that the widest part was 1/3rd up from the bottom. With the stem superglued into the base the combined base and stem was then turned to its final shape.
Top Tip 2 -
The beads at the top of the stem were created using a point tool rather than a beading tool which potentially would have pierced the side wall at the top of the stem. The stem was then masked from between the beaded top to the top of the base prior to colouring.
Top Tip 3 -
The piece was then reversed into a waste wood chuck with a slightly tapered hole to hold the stem in the head stock. The base of the bottom was then turned to about a 1/3rd of the diameter of the vase.
Top Tip 4 -
The base and stem top were coloured using acrylic paints and makeup brushes (under £10 for a large set on Amazon!).
Top Tip 5 -
Finally, gold was added to the base colour using the dry brush technique i.e. with paint on the brush, tap it on kitchen paper to remove excess paint and then flick back and forth over the high points.
Thin Walled Vessel …
Nick uses a lot of wet wood (in this case 32% moisture content) -
Having turned to round and created a spigot the piece was mounted in the chuck and then drilled to depth using a 25mm forstner bit. The vessel opening was increased using a 10mm spindle gouge working gradually down the vessel maintaining a constant wall thckness to within 1/2mm to 1mm tolerance.
Top Tip 6 -
Lemon oil was liberally brushed on to the piece in its final stages to slow down the drying process -
Thanks Mark for a very enjoyable and informative evening -
