Hi Robert,

I work on aged cars and sometimes need to make things move that no longer
want to. Here's what I'd do.

Take the table outside or to some area that won't be damaged by drips and

Try and remove the sliding table from the magnifier so you can get to the
underside. If that isn't easy, remove as much of the unit's electronics as
possible before continuing.

Use silicon spray and a scotchbrite sponge to clean. If there's rust,
you'll want to use WD40 sparingly. Apply light coating of silicon spray
lubricant to moving parts.

It's likely the silicon won't last long, but if it works for a while and
then returns to sticking, you can try something heavier like WD40. If that
doesn't last, I would use (again, sparingly) spray lithium grease applied
with a spray tube. It's stickier than oils and shouldn't spread. Just wipe
up the excess with a paper towel.

At this point you've earned the traditional cold beverage.

Silicon spray, WD40 and lithium grease can all be acquired at auto parts

It's possible that the sliding mechanism has become misaligned or bent
over time. Look for missing fasteners and replace. If it's damaged, it may
be that it's not repairable and needs a complete replacement.
