Hi:

I'm new to the group - please bear with me. I have a BP I bought  a
while ago and need to remove a broken knee gib - sounds like a common
 event. I ended up cranking the knee to the bottom and ended up
turning  the jack screw low enough to cause the bevel gear to come
off the jack screw. then  tried pushing up the bottom of the gib with
a J bar (not a good idea).  I've talked to lots of people about this.
One suggestion is to remove  the head, ram, table, and saddle and lay
the column on its back. Seems  like it might work - I wouldn't have
to fight against gravity wedging  the gib any more than it's already
gone! Another idea was to drill and  tap the top of the gib, put a
bolt through a plate on top of the knee  and tighten the bolt,
hopefully lifting the gib. Seems like I wouldn't  be able to get a
decent sized thread in it, though.

Any comments would be welcome. Also, anyone have ideas of the weights
 of the parts (head, ram, table, knee, column; I might be putting
this  beast in my basement through a small (half door) vertical
opening 4  feet up from basement floor and no tree outside to tie
off to. Rock and  rubble foundation, etc..
