Why shouldn't Jacobs chuck be used for sanding drum?

I have heard where the Jacobs chuck (drill chuck) should not be used in a "lateral stress" position such when used with a sanding drum. Can someone give a reason why not? In a related question: I have a sanding drum (Craftsman) that has a 3/8" arbor. I have the 1/4" SS router chuck:

but there apparently isn't one with a 3/8" hole. I suppose I could order a 1/4" and bore it out to 3/8" but would surmise that it is hardened. Suggestions?
Regards,
Dwight

I feel it would be really hard to generate enough force when sanding to cause any problems. If you were going to be say routing then I would worry....
Heck shopsmith sells or use to sell a set of smaller dia. sanding drums designed to work in the drill press. I have that set plus another set from somewhere, may be sears or ??? I've had them and used them with no issues.

In /complete agreement with Ed! I use the drill chuck all of the time for drum sanding. Even with the SS Shaper/Drum Sanding Fence Kit.

Gentlemen,
Thanks for the input. I have seen a number of drill presses used in rural (farm) locations where one uses what one has rather than the best tool for the application. Cannot recall every seeing a Jacobs's chuck that did not do what it was suppose to. I'll continue sanding away.
Regards,
Dwight

This only applies when the chuck is held in by a bare taper, Morse or Jacobs. They can fly off with side loading. Does not apply to ShopSmith chuck attachment.mike t
