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.

If you have a Jacobs chuck you can just look in any catalog to see what
key it takes. If you don't then even if you had a table of all the Jacobs
key sizes what good would it do?
