Turning on a VOR

Absolutely spot on - at least for light a/c. These days though, very few faster / larger aircraft will do anything except to lead the turn as required by on-board automatic computation systems such as FMS unless the VOR has been tagged as a 'fly-over' waypoint (such as when it forms part of the SID routing). After overflying a 'fly over' waypoint, the track intercept angle should be at 30° to the course between the VOR and the subsequent waypoint (aircraft is flying from the south to WYP, thence joining UZ28 at BAMVI):
However, if the ATCC had cleared a direct route from WYP to BAMVI, the turn at WYP would not require this 30° intercept, but would be direct to BAMVI.
You turn onto the new heading the moment the VOR indicates station passage. Then dead reckon until it comes alive again then carry out any correction as needed.
No fancy rules or algorithms needed. It's been done for decades successfully.
