I took off the chuck holder assembly to access inside microtome. After putting it back together the lock down lever at rear of assembly which locks the up down left right adjustment wont tighten. Any ideas.

Chuck holder assembly loose

There is a disk that is threaded in the center, along with a couple of holes for a spanner. You need to turn that disk clockwise, so that it will tighten up when you turn the cam locking lever.
P.S. You'll have to remove the bracket for the cassette clamp to see it.
