Phenolic is urea-formaldehyde resin with a linen fabric reinforcement. Not only ancient technology, but that dust is also dangerous. You don't want to breathe it.pehnolic doesn’t seem to be particularly good as a bearing surface. It feels pretty abrasive and leaves powdery residue everywhere!
In my day job (designing automated machinery) I use Igus "J" bearings a lot.In the canard wingroots and other places, we're running with IGUS Iglidur plastic bearings. Iglidur is available as stock bearings and plastic raw material. Its also availaible as 3d print filament.
Even better, but I have NO IDEA where you can find it in "retail" quantities, is "Thordon". It comes in several grades, and in the marine trades it's driven out phenolic in anything greased or water lubricated or "dry running".I'm with Dana, Delrin is an excellent bearing material, I often use it for bushings.
"]Not sure if this is the best subforum, but here it goes!
I have a rudder pedal mount that I need to fabricate. The rudder pedal rotates between two peices bolted together. Plans call for fabricating it our of phenolic, but I want to use delrin instead because:
Would there be any concerns for this substitution? Thanks!
- I have some lying around
- Aircraft spruce is charging me 60 bucks for shipping of a phenolic sheet
- I think the movement will be smoother with a delrin mount
Perhaps a sketch or copy of the blueprint detail would provide a better idea of what you are trying to do. Not sure if you want the stuff for making a bracket or a bushing........I have a rudder pedal mount that I need to fabricate. The rudder pedal rotates between two peices bolted together.
