Any chance someone in the San Diego NC (e.g. Escondido, Vista, Valley Center, Rancho Bernardo, or just North San Diego) could help me stick a pipe through a couple bearings in blocks? Turns out the pipe is slightly too big to fit, but it's far enough off that I haven't been able to turn them down by sticking them on a drill shaft (with a 3D printed adapter) and then spinning the drill while I file and / or Dremel the outside. It's taking forever and it's not smooth.

I can pay less than your time is worth, or trade services if you need something 3D printed, or some programming done or anything with robots. I've done some Mach 3 programming in the past, and lots with Arduinos and Ras Pi's and LinuxCNC stuff. Or Eggs. I have LOTs of Eggs!
 
3/4" pipe is about 1.05 OD, so I guess you're using 1" ID bearings?
That will leave you less than .1" wall thickness (schedule 40 pipe).
How long is the pipe?
Do you just need the two ends turned or the whole length?
What kind of pipe? Galvanized? Black Iron? Other?

Ah, it's not 3/4" ID pipe, it's pipe I found that is 3/4" OD. The bearings are just slightly smaller, 0.72" ID (if I remember correctly) where the pipe is 0.75" OD. Even if the walls would end up that thin, I'm not worried about strength. The pipe is about 7" long. Its just basic steel as far as I can tell, it is not galvanized or black iron.
 
What length of the tube do you need turned down? Full 7"? Only both ends?
