Re: DIY Delrin zero backlash nut tightness problem
I haven't hads an issue with the delrin nuts I use (DumpsterCNC)
The acme rods I got are the generics from Roton(1/2"x10 double start)
I use a way oil on the rods (k68)
Not sure how many miles are on them now, but there is minimal wear.
They have been in place for about 5yrs now. Still maintain minimal/zero backlash.
Not sure if I like the idea of painting the rods, getting an even coat on them would be tricky.
And if/when the paint starts to wear and flake off, would generate grit and wear the nuts even quicker.
