Funny... I had to pull some larger retracts to bits today myself. I collected a powerline in a fatal dive and ripped the retract out. Somehow it managed to bend the worm drive. There was a small dent in the trunion.
Larger retracts are so much easier to work with. I removed the worm drive and managed to straighten it almost to perfection. Reassembled after lightly greasing the gears and it is working as good as new again.
Then I had to replace both stubs as well. Now I need a plane to put them in as the other was sold to Redhead for matchsticks.
