You know that bolt thing for the middle of the nova chuck to do bowls on? What size drill for that? I have some bowl blanks that haven't been turned because I've forgotten!!! :)

just measure the size of the solid part between the threads and that is the size of the hole needed to get a good bite on the timber

Liz, according to the Teknatool (http://www.teknatool.com/products/Chuck_Accessories/SpurCenter.htm)site, an 8mm hole is required.


Hole size for Woodworm Screw :

The 10.5mm thread of the woodworm screw requires a drilled hole about 8mm (5/16") in diameter. The screw has considerable holding power and it is sometimes difficult to unscrew, so wax or oil the thread before mounting the wood.
