Simon’s next item was an acorn box with a screw on lid which is where he demonstrated his latest tool for sale. A thread cutting set up.
The cup with stem was turned from American walnut and the acorn from ash. He turned the acorn first, roughly shaped the outside and hollowed it out to take the thread and hollowed a little deeper behind to clear the cutter.
The cutter was mounted in the lathe chuck and the box held in a chuck on the jig.
At a speed of around 400rpm he brought the box up to the cutter then wound it in to set the depth of the first cut and simply wound it in across the cutter.He repeated this until the thread was complete.
To stop it tearing he treated the last cuts with super glue before taking the cut.
Next he turned a spigot on the piece that would become the cup to suit the thread diameter then mounted this in the jig chuck and cut the male thread, testing it against the cup to ensure a tight fit at this stage. With the two still together he mounted them back on the lathe and turned both the acorn and the cup to shape but before parting them off he unscrewed the acorn and lightly eased the thread to a slightly looser fit.
To part it off he hand sawed it at an angle to give the impression of a stem.
Simon then turned another plain box to demonstrate thread cutting using hand chasers.
After this Simon demonstrated another of his tools (for sale!!)
This was a sphere cutting jig. This is mounted in the tool post and the diameter of the sphere is set by adjusting the cutter to suit. You can rough turn the sphere before bringing the jig in to play or with light cuts you can use it from the start. After taking it down as close as you dare at the spigot ends remove it from between centres and snap the spigots off. To finish off mount the ball between cup centres and turn the waste away using the shadow outline as your guide.
To polish it Simon used different mops fitted to the chuck and used Carnuba wax, White diamond paste and Triple E.
Geoff Hunt reckoned “it was a lot of hard work for something to chuck at a coconut”
Next item was a salt shaker shaped like a sea shell. He turned a block of spalted beech to round between centres and formed a chucking spigot at each end. And cut it in two. He mounted one piece in the chuck and turned the base and hollowed a recess then turned it round, shaped the outside and hollowed it out to contain the salt. The top was then turned and hollowed out and a spigot formed to fit the base. A 5mm hole was drilled in the top for the salt to pour out through. The top and bottom are held together by wrapping waxed hemp around the spigot to form a tight fit.The base was sawn off at an angle to give the sea shell appearance.
Simon’s last piece of the day was a bowl to show the effects to be gained from the Robert Sorby texturing tools.
There will not be a meeting at Milstead this month. Dawn has arranged for us to meet at Stiles and Bates where we will be given a demonstration of cutting tree trunks in to planks and planks in to bowl blanks. I think there may be a bit about this on the club website from a visit that Fred and Dawn made at another time.
If you would like to see pictures of our trip May 2017. they are available in the gallery "stiles&bates April 2017
There will also be a discount offered on things you buy in the shop. Ideally bring a packed lunch with you because the nearest watering hole is some distance away.
See you all on the 13th
