Drawer slide corrosion

[Mschmidt]

I would like to make some pull out shelves/drawers to sit over my sump in the cabinet. Only questions are: what's the risk of corrosion to the slides? What sthe risk of that corrosion falling into the sump?

You could use tslot and sliders. It worked very well for a t5 setup on my 120.
Standard ones will rust and fall apart over time.

I'm unfamiliar with the sliders. They plastic or aluminum?

I got a little dehumidifier I run in my cabinet. I mean to take it out of its plastic case for size and have it drain directly in to the sump but its so small and isn't that much of a pain to empty so I havent addressed it yet.

It has kept the sliders I use for my control panel rust-free for over a year so far.

Could also fabricate something out of Delrin, expensive, but self lubricating and plastic.

There's a thought. don't have to worry then about the wood getting ruined then too. Not a fan of painting.

Might look into epoxy coated drawer slides and use plastic/resin wheels with them.

or

A bit more expensive but great option.

a bit more? That's about what I'm looking to spend on the whole project.

Stainless steel slides are available:

An occasional wipe down with a water displacing oil (WD-40) should help extend their life.

FWIW WD-40 does very little to inhibit rust or lubricate, and in most cases makes matters worse.

Interesting, that has not been my experience, but I will admit I have never used it for this specific application. Ture it is not a lubricant, but I have used it for its intended purpose (water displacer) and also to lightly coat raw steel and cast iron surfaces to prevent rust and it has worked well for that. YMMV.

I'm sure there are better lubricants/protectants for the purpose in question.

They may get surface corrosion. The reason I use Marine grease on my hardware.

Decent a water displacement. YouTube ProjectFarm does fairly well balanced tests of stuff like that. Wood magazine and finewoodworker did rust tests for table saw wings, etc.
