This post is a follow up to my recent question asking for help on getting the outfeed table on a used SCMI F410 to move.
I managed to free up the table, I guess it was "frozen" in place perhaps by the lubricants gelling. It weighs a ton, and I used an engine hoist to lift it back up.
My question now is how on earth can the threaded rod that raises / lowers this table actually work?
Right now it doesn't work, I cannot move the table using this knob and rod.
The rod threads into a rectangular collar on an axel that pushes the cams and thus moves the table.
But, at the end where the hand knob is, the rod simply comes through the body of the jointer, through a nickle plated cover and then ends in a knob.
So when the knob is turned, the rod does not push against anything, it is not captured, and so physically how can it apply any pressure against the cam axel?
It doesn't make any sense to me, yet it seems to be this way when I look at the exploded schematic.

To my mind there would need to be a nut in the bump of that cover plate for the threads on the rod to push against, but there is nothing there, and it seems that this is by design.
If anyone has any insights or knowledge about this I'd really appreciate you sharing.
thanks, Mark
