Is there a way to bevel the ends of Cylinders?

I am trying to figure out how to cleanly join 2 cylinders (or Tubes) into a Corner

I think the term you want is mitre (or miter), and no, I don't think you can mitre a cylinder. It'd be nice if we could taper prims on all three axis.

I take it the walls are too thin to just embed the end of the cylinder into them?

To make the appearance of a beveled cylinder, here's one thing you can do. Take a tube and then taper its top. Since the "top" of a tube is actually a spot on its circumference, not either of the flat sides, this will cause two flat ends to tilt towards the tube's equator. Give the tube a profile cut to remove one of the ends, so that the tube appears to have one horizontal end, and one tilted end. Now, path-cut the tube so that it's circumference becomes a D-shaped instead of circular. Duplicate it, rotate one of the copies 180 degrees, and place the two back to back with each other. You should now have what looks like a cylinder that has been beveled on two sides, to come to a point in the middle. Or I should say a line, not a point, since it will extend all the way across the diameter.

Since SL is closed right now, I can't get in to test this myself, but if I'm picturing it right, it should work.

If you're tricky enough with it you CAN achieve such shapes with a cylinder prim. I would lay out what angle I want, and rotate the cylinder (45 degrees, assuming a square corner) to place the bottom end (not top; make sure it's rotated right) flat against the corner angle. Then, I'd stretch it across that angle, TOP SHEAR it all the way to .50, and bring in the top side (Stretch Both Sides OFF) until the angle matches.

However, this cylinder technique ONLY covers the corner. To cover longer lengths, take a Tube, turn down its Hole Size, and Top Shear THAT. Actually, that's probably a bit easier to work with anyhow, as the circular ends of its cylindrical shape will be changing angle rather than the sides.

Thank you, I appreciate your research and the sample. It will take some practice to get this to a point where you can build predictable dimensions and angles..
