RF30 Basement Install

Excellent point. On my shop made ones I used a center punch and “smashed” the last thread on the bottom to prevent the bolt from freely threading through.

I have to do that with some of the commercial ones I have. The last few threads are tight but not tight enough.

I've had rework some; not many. Lots of commercial stuff needs tweaking. Not tied to overseas or domestic. Just poor quality control.
 
HELP!!!!! I'm in over my head and don't know what to do.

This is a far as the X-AXIS gib will seat by hand. If I force it in any deeper it binds the table up so tight you can't move it by hand. I have stoned the gib for well over two hours now with no real effect. I inspected and felt all the mating surfaces and don't see or feel anything that might cause this. I do get the impression that the gib is a little bowed over it's entire length. Maybe it needs a tune up on a surface grinder? DUNNO, I'm at a loss:confused:
 
Are there any lateral screws that are used to secure <lock> the table? If they are protruding in a bit then the gib wont slide. Pic of my RF-45 as example

My table (especially the Y-axis) is tight toward the extreme ends of the travel. Put the table in the middle of the travel and see if it's any better.

Been there done that, it's worse

I can get the gib in all the way in if I do this, but, as you can imagine most of the gib is just flapping in breeze in this configuration.

When I attempt to push the table back to center she jams up tight about 1/3 of the way and I think the only way I could get her to move is to install the lead screw.

Take the gib out, slide the table to the middle of the travel, push it all the way toward the column and see if that makes a difference.
(it came out of there so it has to go back. It's just a matter of finding the right combination.)

I have already tried that a dozen times now, it's the same or worse than when I attempt to install it with the table extremely left.
 
Just out of curiosity what does the other end look like #232 sticks out a fare way is it possible to turn it around?

When the table is in this position, does it change anything if the table is shifted to the right slightly?
 
Let's see...… I need a proper vise for sure, and 3-axis DRO is a given. As it stands, I don't have the T-NUTS to mount anything on this thing right now LOL.

Any one have two 1/2" T-NUTS and bolts to spare?

I have a whole extra 1/2" t nut clamping set I'm selling. Like new $50.
