Thanks Ducsauce / Greg for the replies.

Greg,
I printed out your instructional thread and your chuck looked as though it was some type of aluminum or metal encasing that had a rubber grommet on the inside to hold the arrow in place. The rubber bohning chuck I purchased was literally the only one I could find ANYWHERE.

Ducsauce,
I alsobelieve that it is the chuck making the circular motion. Is doesn't have a true spin when attached to the shaft. If you try the surgical tubing; could you let me know how it works out for you or if it is a sewing machine rotational problem. I appreciate the help.

Does anyone else seem to have this problem with theirbohning chuck?
