Rollers need ro be turned smooth and accurately round, even if you make end caps for plastic tube, the combined drum should be turned as a whole.......
I believe most commercial rollers have a saddle-shape taper from both ends to the middle so they help keep the bike centered in use. Completely cylindrical rollers are more difficult to ride.
