I had this interesting idea the other day.
To build a fiberglass tube, why not either laminate phenolic with cloth and resin to a thickness over your desireed one, and then put it on a lathe and turn it down with a tool bit to your desireed thickness and finish with sandpaper. Would this not avoid overlap problems and wavey sanding?
I'd appreciate any comments or suggestions.

Why not just fiberglass it as normal, and then sand the tube on the lathe? If you tried to turn it round with some type of machine tool, you'd likely cut through the tube before it cleaned up, or at best, leave it very eccentric. (and weak)

How biga tube you talking?
I sand and lay epoxy coatings down while the tube is on a lathe. Open mess sand paper doesn't clog as much. You can make a lathe from pillow blocks, blower shaft, pulleys and an old fractional HP motor with a speed controller. Gary Deaver
Also - you may want to try adding a layer of something you don't
*mind* cutting into... a layer of light fiberglass or paper, which you don't consider 'structural'. Something that you can sand the crap out of, and not have to worry about damaging your reinforcement layers.I've used Kraft paper with moderate success - I'm going to try
1/2-oz fiberglass next, and compare the results.This method in the link you supplied looks much more efficient than using a real lathe. Also, I wouldn't want all that fiberglass crap getting into the guts of my lathe.

Interesting stuff on this site. One thing I'd do slightly different with this sanding stand is to flip-flop the motor to the OUTSIDE of the unit, so it doesn't ingest as much of the debris that falls from the sanding jig. And make sure the motor airflow is from the clean air to the dirty air: I ruined a compressor motor years ago when it sucked up all the paint dust and got VERY clogged up.
