Nova Midi Chuck Question

[dhallnc]

When referring to the jaws, what does the measurement refer to, such as 25mm
50mm ect.?

Is it the jaw width or depth?

Thanks.

Diameter --

The 50 mm jaws hold a nominal 2 inch diamter tenon - Nova jaws like a dove tail. The 50 mm jaws fit nicely in a 2 1/4 hole for inside holding.

The 25 mm jaws are designed to fit inside a 1 inch hole. They will close down onto a small diamter rod/piece -- you can use them to turning a bird house onament perch.

The 25 mm jaws or better the spigot/pin jaws work well for holding pen blanks.

(I have that chuck) - there is a table on the Teknatool site with the max and minimum inside/outside dimensions for each set of jaws - and on the back of the box.
