That is one of those flex-drive things… so no pulley/belt to hold onto unfortunately. I’d be very, very cautious about drilling/tapping the shaft for a bolt… it will most likely throw things out of balance and properly drilling the hardened shaft would be a difficult task by itself.

The manual states that you use the block of wood method for removal/insertion… so you are doing it right. Make sure you are pulling the wrench towards you. The arbor nut is probably frozen on the spindle from being in place for so long. I’d try giving it a good squirt of penetrating fluid first and letting it sit for a while. Then try tapping the wrench as mentioned above… which will in effect be acting like an impact wrench. A little heat would probably free things up as well. If that doesn’t work, you might be able to take the flex shaft off the motor or figure out a way to keep it from spinning there, and then doing the impact thing.
