Removing that stubborn crank pulley (harmonic balancer)

I came up with a new way of both loosening and tightening a 430 crank pulley bolt, that also allows you to torque it up to the right level also. See here https://www.youtube.com/watch?v=3czUeI7IlWE. Also, the bolt you use doesn't need to be threaded into the pulley - just a snug fit part way in
There's an insane amount of torque + lock tight on the crank bolt. That tiny little bolt half way threaded in will bend or snap very easily.
I tried making a much stronger holder using 2x4 wood with holes in it on my ES330. I ended up with twisted bolts and split wood. Had to resort to a 3/4 impact. And yes, it was a virgin pulley.

I have high doubts in that working on a vehicle that has never had its crank pulley removed since the factory.

I've used my method twice in 430 engines, one 12 years old with 70I miles and the other 15 years old and 62k miles, both of which were on their original can belts as I knew the vehicle history for both. The bolts didn't bend at all, either from undoing or retightening the crank bolts.
