Well for the most part the fly wheel wont let me push it in so as far as it falling in as a whole i guess im safe. Some people were saying little pieces falling in there it shouldnt be a big deal.....I mean personally im going to try my best to keep that from happening, but i am going to attempt what i mentioned in the previous post and hope for success. Otherwise im going to be drilling through that magnetic part (assume thats whats left in there) into the fine powder it seems to been becoming as i chipped away at it, until its empty and i can dremel anything remaining to make way for the new one.
