Here is a thread on a recent discussion of the same problem:

Do you mean the gibb is not moving with the knee?
a couple of methods are usually used to ajust a gibb, look on the end of the gib for a allen screw and locknut, if you have this method, you need to unlock the nut and undwind the allenscrew through the centre, tap the gibb in the direction away from the screw.
Other methods are usually obvious by locked screw in the knee same side as the gibb.
If you can determine the narrow end of the gibb by looking at both ends, it helps in which direction to remove it.

mr. dung
would like to see this discussion, but my system at school wont allow me to visit this for some reason they have a firewall blocking me, any advise on my problem with machine?

[HuFlungDung]

Yeah, tell the system admin to permit access to the PM forums. There's nothing x rated going on over there and lots of good advice for machinists, and wannabee machinists, and yes, Chip sweepers
