Just curious if anyone has used this drive center for bowls. I use my spur centere drive often, this would keep me from removing my chuck so often.

Thanks for the information. I guess I'll just keep using the mt spur drive that came with lathe.

I may be wrong ... I often am. I thought they were made to provide a drive with high tenacity in dry wood with minor penetration and not to slip.  That said I do not use mine with most bowls, especially green wood.  They will slip easily because the wood is so soft and even act as a drill.
In looking at your pic I notice a major difference from mine so maybe there are two styles?
In your pic the "teeth" are V and appears a little flat on the end which would be easier to slip.
Mine is like your spur drive with the "teeth" at a l/ shape.  The flat seats against the wood and the point is very sharp to bite in.  Like a 18 spur drive instead of a 4 spur.

The one In the original post is made by nova or at least sold by them to fir their chucks.  Chris, do you use one like this for bowls. Nova also has a steb center that will fit in their chucks. Just trying to figure out which would be best for starting bowls.  Thanks again for all the info.
