Yeah sad fact to replace the Plastic ends from time to time, but that's about it hey.
I personally detest the feeling of the plastic on metal and do lubricate these every else and a while, but now that I have bought myself a lathe, I will look into making a few ends caps to take sealed bearing and set them into them.
I have a few neighbours that are also keen to replace these with bearing types. When I get the chance, I'll post my units.
