Have You Checked Your Gibs Lately?

[Janderso]

I watched a video yesterday by Kieth Rucker. He adjusted the gibs on his K&T mill.
I believe the specs were .0015” for the table and apron and .0005” for the knee.

I spent a couple hours this morning removing wipers, cleaning and checking the operation.
I then checked the table movement, it was right at .0015 ish.
I had removed the table to repair some oiler lines when I got the mill a couple years ago So I’m not surprised there.
The saddle was about .006” and the knee was .005”.

The method to check is to extend the table and push/pull/lift with the extended end for leverage.
I knew there was slop due to the forces caused by milling, I had noticed movement where there should not have been any.
Funny thing is, the movement of the X and Y axis is much smoother/easier to turn the handles. I wasn’t expecting that.

How long has it been?

Wow! I gotta say...I'm an idiot. I tighten until the just moved smoothly w/o binding. This is much more repeatable and measurable. Always learning I guess. Thanks @Janderso for posting the thread and thanks @Pcmaker for the video post.
