I have been giving a lot of thought about bushings these last few weeks. I ordered a batch of self lubricated ones from China to use with ordinary polished half inch stainless rod and they worked wonderfully.
I tried printing a batch of bushings from PLA+ and ended up making 20 units of the Tinyboy style printer using stainless rod and printed bushing.
Today, acting on a hunch I visited my stainless guy downtown Manila, and he surprise, had some brass tubing that was a perfect 1 inch ID bushing. It fit a little tight at first, but after a bit of sanding with 1000 grit on the stainless tubing, it slid smoothly.
So Im asking why are not using bushings?
