I first bought a Super Nova chuck set and ran into the same issues. However, I concluded that the problem was using a 4 jawed chuck when what I really needed was two jaws. I, too, purchased the PSI Dedicated Pen Blank Drilling chuck and will not use anything else. I experiment with the blanks to see which end spins the truest. This works regardless of the dimensions of the blank.

As mentioned, it sounds like an issue with your chuck. I have no problem holding 1/2" blanks with my Nova pen jaws.

The most accurate of any of the chucks sold for wood lathes are the collet chucks. It is simple to turn the blanks round and then use the collet chuck to drill.

John, the metal pieces with hole that the jaws screw to are called "slides".

They should come together with the pointed ends nested together when the jaws are closed. With both screws into the slide for each jaw there should be no gaps beyond about 1/64th of an inch. The space between flats of jaws should be less than 1/2 inch.

Are the points of the slides together fully closed?

Ken, they don't meet. Would I need to change the position of the jaws? Might that be the problem? I'll be in Chattanooga this Thursday- grandson is taking a pen turning class at Woodcraft. I'll take the chuck with me and let them look at it. Thanks to all for your replies.

Default Pen jaws

It shows the jaws completely closed. Do I need to take out the pieces between the jaws? Just noticed this. Duh!!!! And to think I stayed at a Holiday Inn Express once!

Yes, take the bits out in between. Should solve the issue instantly.

I answered my own question. I removed the two jaws and the pen jaws snug down to within a 1/16 inch of each other. Measuring between the flats reads about 1/2 inch. Believe it or not, after I removed the two jaws, I got curious and read the instructions for the pen jaw installation. There was no mention of removing the two jaws to allow the pen jaws to close. Live and learn. Now I can make drill smaller blanks as we all know that some pens like the Slimline turn down to a very small diameter part. Seems a shame to start out with a 3/4x3/4 blank and turn off most of it to land on the floor of the shop.
Again, many thanks for all the replies from the forum folks.
