b230 timing belt change

This guy removes the crankshaft sensor (I've linked to the video at the 6 minute 44 second mark) and jams a bolt in the exposed shaft rather than using the crank holder tool - this looks reasonable to me and far cheaper than the tool I will likely misplace before I use it again.
Has anyone else tried this method? I haven't checked yet as to whether this is as reachable on my 240 as it is in the video.

After reading up on this method from the UK Volvo Club site, I think I'll either do it the rope way or the right way.

Method 4: Jamming the Ring Gear. [Not Recommended and NOT for LH2.4 cars, Rex/Regina cars, or any car with a crankshaft sensor] Some have suggested jamming the ring gear with a screwdriver or tire iron. DON'T DO THIS: several anecdotes of ruined torque converters, ring gears, and ring teeth have been reported.
Caveat re: Sensor Ring Damage. Don't even *THINK* about attempting this ring gear technique above if you car has a Crankshaft Position sensor. This applies to all cars with LH 2.4 or greater or Rex/Regina. On these cars, what you have access to through the inspection plate on the bell housing is a thin sheetmetal metal ring with little square windows evenly spaced around the 360 dg with two windows missing at TDC and TDC + 180dg (or is it TDC - 90dg and TDC + 90dg? can't remember.) Either way, these little windows look like the perfect place to put a square shank screwdriver, but the sheetmetal ring is very weak and if you bend it even the slightest there's a good chance your fuel injection system will get highly confused. I believe that if the ring is even 1mm out of round, the pickup may miss one or more windows.
