This picture just shows a few of the different 3 sided bowls I have turned......these were shown at the beginning of the demo to the audience. Note the two lidded forms....one with contrasting wood and finial added.
Demonstrating the high points on the start of a 3 sided bowl demo - these bowls are started from a cube of wood......not turned round and then the sides cut with a bandsaw as many believe them to be!
This picture shows the special jig made for cutting the corners off the cube shaped blank. When using a bandsaw, one has to be very careful.......this jig allows one to keep fingers away from the blade and makes the cut safe. There is a notch cut into the side where the corner of the cube shaped blank rests to give it stability.........a firm grip is needed and the blank is eased into the blade.
This picture shows the shaping of the outside of the three sided bowl..........see the shavings flying off the gouge ......note the speed [rpm's] as this is a turning in which on a lot of the form, it requires the utmost of concentration and fine tool control, because the gouge is only cutting at three points in a rotation......meaning most of the time the turner is cutting air.......because of this lathe speed being higher allows for a more consistent cut.
This shows the turningof the inside of the bowl......here a scraper is used to refine the surface of the inside of the bowl.
This pic shows reversing the bowl and preparing to turn off the tenon on the bottom and refine a foot for the completing of the form. Note the plywood disk with the pad on it, used as a jam chuck. There is a faceplate on the backside of the disk, which threads onto the spindle of the lathe.
