My team can get pretty jealous of southerners who love to post their photos of practising or testing outdoors, even in January. Last night, we finally found an advantage to the cold.
We were sanding a delrin bushing down to perfection. Although material was clearly coming off, subsequent measurements showed that the bushing was staying the same size or even getting larger. A quick calculation showed that heat generation was causing it to expand the few thousandths of an inch to make the difference. A simple solution was found right outside our shop door.
Clever use of your resources. Machining delrin to a nice finish is tricky, but it can be done. Is that why you are sanding, to get a better finish?
If so, then guiding the inevitably long/ stringy chip away from the cutter to prevent it from wrapping works well. No need to move to sanding.
Remember to remove the water from the lathe!
This makes me happy. Every time I hear about a southern team working outside, I get jealous. But none of those teams would be able to use this solution, so maybe us northern teams aren’t so bad off after all.

How is that possible? Connecticut is considerably farther to the south than Seattle, but I’m still inside my house freezing inside a winter jacket.
Hey we have problems down here too. The massive Florida humidity causes our drill bits to rust out within a single season, and it wreaks havoc with PLA and nylon filament. The extruder on our printer practically steams with all the absorbed moisture.
