Spindle Turning
Sea Shell Salt Shaker
(don't say this too quickly, Simon couldn't)
Demonsration by Simon Hope


An entertaining and informative demonstartion by professional turner Simon Hope.

Simon Hope, the well known professional turner gave an intriging demonstration, which provided new ideas for projects, tips on tools (mostly his own brand) and their use, design detail along with a few jokes.


Project 1
Sea Shell Salt Shaker


A Sycamore blank of approximately 75 x 75 x 150mm was mounted between steb centres.  
This blank was roughed down to a cylinder, and then a spigot was formed to each end to suit the chuck jaws.
The cylinder was marked out for parting off, at about a third of the way along. Part off most of the way, but not right through. Stop lathe and saw through.
Start with the smaller section, form the basic shape to outside, using bowl gouge.
Start to hollow by boring a hole in the centre with the spindle gouge similar to a drill. Hollow using a spindle gouge. Form rebate to top edge and continue hollowing using a Simon Hope  hollowing tool. Simon said that he deliberately leaves a pimple in the centre, but having bought one of his hollowing tools after the demo, I can say that it is very difficult to remove the pimple with his hollowing tool. Sand the top edge.

Now mount the larger portion in the chuck.
Form jam chuck for lid section, make this a snug fit then wet the lip and fit the top on, leave for 10 sec and then try to pull off. Wetting the lip makes the wood fibres expand, giving a better grip for turning the top section.
Shape the top gently. Use a spindle gouge to hollow out centre, then use the Simon Hope hollower. Masking tape the lid to help prevent the two parts accidentally flying appart. Use the S.H. hollowing tool. Hollow out to a thin wall. Mix bees wax and baby oil to help form a paste for sanding, this helps to give a finer finish whilst reducing the dust levels. Reduce speed whilst sanding.
Remove masking tape. Check the lid is still a tight fit, and if so sand the outside.
Now stop the lathe and cut the top edge off, on an angle, using a tenon saw or similar, try to loose the endgrain.
Sand to shape using a jig if you like, or just an abrazive and a cork block.
Now start to shape the base, with bowl gouge to form 2 basic large beads.
Start to core out the base with a sindle gouge as before used like a drill, then continue with the S.H. hollowing tool.
Finish inside then return to the outside to fine tune. With a spindle gouge, form a small groove to top lip to fit a waxed hemp seal into later. Lightly sand to 240 grit.
Tea break time!!

Now make new jam chuck from a small bowl blank mounted in the chuck.
Face the blank off and form jamming point, making sure its a tight fit. Wet the edge as before for extra grip.
Shape the outside to form a onion style shape and blend to give a blunt point.
Drill 2.5mm hole in the blunt point for the salt.
Wind waxed hemp into the groove formed earlier in the top lip until a tight fit is achieved. The waxed hemp will need bedding in slightly.
Fill with salt. Complete!


PROJECT 2

An Off centre candle stick.

Based on an original design by French Turner Jean Francois Escoulen Click here to visit his website

Take a blank of wood (Ash in this case) 65 x 65 x 180mm approx.
Mark diagonals to each end in the same direction as each othrer. Mark 10mm from each corner towards the centre for your mounting points, these points must be opposite to give an off centred but balanced blank when spinning.
Remove the ghost shapes from each end, ie the high spots.
Now turn a spere in the centre whilst cutting in steeply using a spindle gouge, which has well ground back wings.
For the design to work, you need to get edges of shere about 10mm lower than surrounding wood, this does require deep cuts with the spindle gouge.
Clean up with a skew to give a deep crisp vee where its meets the sphere.
Re position the blank on normal centres. Remove the edges, ie rough down but not all the way. Form a second shere, outside the first, this can be seen when spinning. Make sure all the flats are removed. Use skew again to clean up the deep Vee.
True up the base section and shape a bead and cove to form the base.
True up top shape and form a similar but smaller shape than base.
Done.
It sounds simple but looks a little tricky, one for the more experienced I think!

Sadly we have no photos this month, only one of the finished Salt Shaker.
