I came across this thread on OWWM from several years back and it gave me a bit of pause...anybody have anything to say or add regarding these findings? Wondering is this affliction is universal or only specific to saws with overly worn bearings and how to remedy the problem if the sliding table bearings are unobtanium.

I've been trying to get the sliding table adjusted properly. I have the manual and have been following the directions but am having a heck of a time getting consistent travel along the entire length of the slider. Because this is not a new saw, I'm worried something might be damaged. Hopefully, it's just my incompetence. Any hints?
No worries, that saw has a design flaw in the bearing setup. There needs to be an extra set of bearings for the table to travel on, so when the slider is pulled to either extreme, there is excessive slop in the table.

I'm just a noob with table saws in general, let alone sliders, but that seems like a pretty major design flaw. Isn't one of the big advantages of the style to be able to make very accurate, repeatable cross-cuts? Is there any was to do a fix or work-around? Or is it not such a big deal?

You'd think SCMi would've noticed that, but they may have missed it. I think making sure all your bearings are aligned properly on all axes should minimalize the issue. If you keep it riding on all three bearings, you will be fine, it's the extremes that cause problems.

I've got most of the slop out by very carefully aligning the bearings. Just a bit at the extremes as Sal mentioned.
The slider is parallel to the main table but the main and miter slot are not parallel to the blade. I've aligned a table with blade on a Unisaw but of course it's much lighter. Should I use the same technique (loosen bolts, tap/pound table into parallel with blade)
