greets all..
having some trouble using/diagnosing the powerfeed
on a Jhead bridgeport.

i can get it to engage in both directions... "Up" has
alot of power, i can't stop the quill by pulling on it.
however, downfeed seems to kick out with little
resistance.

ie, using it to drill holes.. it'll feed down, but
as soon as the bit touches the workpiece, out goes
the powerfeed.

anythoughts? is this thing broken? or am i not
engaging it correctly?

any help appreciated.
