>Someone asked why he was told not to use a goughout gouge on a bowl blank. A lot of people said the tang was too small and might break. This is true but what makes the gouge tang break is the force created on the outer diameter of the blank. Most spindle work is limmited to about 4" or less and a roughout gouge can handle this. The force on a blank to make a 12" bowl is much greater with the lathe running at the same speed. I am sure there is a formula for this but you can see and feel the difference the size of the blank makes as you turn up the speed. My lathe will take a blank almost 24" across and I start roughing so slow you can almost see each corner as it passes.
