The maint manager of a largish factory..a good friend of mine
actually, died unexectedly a couple weeks ago. Damnit.

But one of the unfinished projects he left behind, is a BP with a
jammed/broken gib in the knee.


From what I gather..its jammed really good. When the facilities

manager asked me if I wanted to take a shot at it...he pointed out
that there is about 3/4" of gib sticking out of the bottom of the
knee..which is NOT a good thing.

Anyone have any secret tips, suggestions/angles of attack on how to
get the bitch out?

Currently they have the screw boss unbolted and hanging..so the table
is being entirely held up by the gib.

This is a bitch of a task at the best of times, so before I tackled
it...(either I fix it and they pay..or I dont fix it and they dont
pay..bet between me and the manager...sigh) I thought Id ask about
any tricks that I may not be aware of. But Im obligated to try.
Shrug.

Thanks in advance

I don't know if it would work or not, but possibly a pipe clamp (like
used in woodworking) positioned under the "sticking out" part with
the other end on top of the knee and then turn in the clamping
screw...
Ken.


For that it's worth:
This is "out in the wind" as I don't have first hand experience but...
Place a hydraulic jack under the knee and put a couple of tons on it. Then
another jack/big hammer/drift carefully rigged to bear on the bottom of the
gib. IIRC the gib removes upwards.

Ken.



If you beat on the bottom of the gib it will expand and make matters
worse. You have to lock the gib in position and then push the knee
downward, holding the gib stationary to the base.

The big problem with BPs..is that the area directly under the gib is
dished for coolant. There is NO flatspot you can put anything like a
jack on and get a straight up push. Im thinking about laying a piece
of railroad track across the dished area and using a very short
automotive scissors jack as the first attempt, with a chunk of 4x4
between the top of the table and the bottom of the ram to hold it in
place.

A portapower with the short ram might be interesting..but I dont have
one. Shrug

Drill a hole in the gib and way and put a pin in it.
