Can anyone direct me to a chart for chuck-key dimensions. I want to
order a few but the catalog lists about ten or a dozen sizes and I've no
idea what mine is. Besides, a chart would look good on the shop wall (:-).

I've done google searches till I'm blue in the face and even located a
website for Jacobs ( http://www.jacobschuck.com/ ).... possibly the most
useless site I've ever seen.

Better to search for your chuck # to find the correct key.
