Thanks. This is along the lines I was expecting, I just didn't know what products to try for best results.

Have a great 3-day weekend!

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 damp.

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 stores.

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.
