Topic tags/keywords: woodturning bowl help turning

I am a beginner woodturner. I have a Rikon lathe and a Nova Midi-chuck. I have been having trouble forming the bottom of the bowl that would go into the chuck. I try to form a dovetail but it doesn’t hold on the chuck. I’m not sure how long the wood should be to firmly sit in the chuck. Does anyone have any advice for me? Thanks. Mike

i try and get at least a 1/4 inch lip to hold on to the chuck. it works well for me. also don’t make the whole to big.

Mike,

Roper’s comment about the hole size is important. When you open the chuck jaws, they no longer form a circle and you loose contact surface area inside the recess formed on the bottom of the bowl. Try to make the recess hole just slightly larger than the minimum chuck diameter. Also, when you mount the bowl, bring the tail stock up and set the live center into the “top” of the bowl. Then turn the outside shape. Capturing the stock between the chuck and the center will provide more support while roughing out the general outside shape.

Also make sure your dovetail matches the angle on your chuck. If the dovetail angle does NOT match then you will have very little support.
