This evening was packed with activity.
We had an excellent entry to this evenings competition of "thin wet turned flowers", most entrants didn't stop at producing bunches of flowers but also producing weed pots or small vases in which to display their flowers. John Navin was judged the winner of the experienced entry and Bernie George the winner of the beginners, full results and pictures of the entrants can be found here.
Derek started the evening activity with a demonstration on multi-axis turning. This will be the subject for the May competition where entries must contain a significant content based round multiple axis turning. Derek started his talk and demo by handing round various examples, some good and some rough (to say the least!!) of the results of his experiments using two and four axis. He highlighted the need to number the axis before starting turning as it is very easy to use the wrong centre and hence end up with another entry to the scrap box!
As well as numbering the centres on each end of the spindle it is also advisable to record which centre at the head stock goes with which at the tail stock. Failure to do this not only fills the scrap box it will also make it difficult for you to repeat any interesting shape you come across. Because when using multiple axis you are turning in air a lot of the time you should be using a fairly high lathe speed, I used 2,200 rpm.
The above are just a few examples of shapes that can be obtained using multiple offset axis. I found that during my experiments it's certainly worth playing around with various combinations of centres at the two ends of the spindle to see what shape is hidden in the wood, you should also consider using a true centre at one end with offset centres at the other. The distance of the offsets from the true centre also can have an effect on the final shape obtained.
We were pleased to see more members than ever bringing things for the show and tell table. We had examples of flowers (some of which which got too thin) , some home made gouge sharpening jigs and various other items.
After a short break for drinks John gave demonstrations using both his Tormek and Robert Sorby ProEdge grinding machines. He also showed the use of various of his jigs and burring tools, he also used his machines to regrind the gouges for a couple of members.
Les brought a long his Creusen slow grinder together with his Wolverine grinding jigs, Les too used his machine to regrind members gouges.
Hopefully members enjoyed this evening and we look forward to interesting shapes entered in the May competition.
