I thought out of idle curiosity I would measure the accuracy of my Warco A1S
mill table now the mill has had a few years use and I thought it about time
to adjust the gib strips. Over about 18" movement I had 3 thou error on the
X movement. Is this typical? mediocre? bad? good? or what? for an early
imported machine. Seems to be due to the weight of the X table transferring
from one side to the other as it over hangs the Y table and Knee.
I cannot say that the gib adjustment is straight forward. The manual is not
a lot of good and the drawings do not even show the gibs. They appear to be
long tapers from both ends. So I reasoned that tightening them from both
ends would be the obvious adjustment ....... no that doesn't work .....
seems you have to loosen one end and then tighten the other .... but which
end to loosen and which to tighten? Tried both ways with no obvious change.
I would expect to be able to lock the table by such an adjustment.
Anyone got an A1S that knows how the gibs work?
