Lubricant for our RepRap Moving Parts

[Gary Schwartz]

Essentially every readily available lube I've considered has some nasty ingredient that's not ABS-friendly.

 

EXCEPT: Engine oil.  ABS is commonly used for engine oil funnels and engine compartment components.

 

Engine oil has film strength that probably exceeds any of the wonder lubes we see on hardware shelves.

It has anti-corrosive properties.

It's available in a variety of viscosities.

It's cheap.

It works.

 

I made a bushing out of hobby shop brass tubing.  The OD of one size is a nice slip fit into the ID of the next size up.  I tried several lubes that didn't do the job.  Some cheap 10W-30 works beautifully.  And I'm not concerned about the well-being of my ABS parts.
