I just picked up an older 3520b from a friend and it has been I a storage garage for over a year with a One Way Talon chuck on. I can not get the chuck off🤷🏻*♂️🤷🏻*♂️ I am locking the spindle and using a half inch bar as a lever pulling towards the operator position. I can’t figure it out. Rust? Checked for a lock nut but didn’t find one. Need some ideas
