Forgot to mention that the Delta has a pneumatic
drum option that attached to the outside of the
fixed end of the drum shaft. The pneumatic drum
also has a dust shroud option - a necessity unless
you like everything in the shop to have a light to
medium dusting of whatever you've been sanding,
to say nothing of clogged lungs. Drum sanders
generate an amazing amount of very fine dust
Think Mount St. Helen and scaled back - just
a little.
