shaft issues

Well I finally tried to replace a shaft with the grayson hobby replacement today. I was waiting for it to be wobbly but it was nice and tight in the bell part. I thought cool!. (Yeah, right.) Then when I tried to slide the bell over the windings, I couldnt. It was so out of line it wasnt funny. Couldnt figure it out, so I got on here, and found the answer in Sanman's wriitngs. He mentions that he mayve bent the can when he hit his. So, I had a shot stock motor here that never flew and I cannibilized its can. Everything fit like a glove.No wobble, no nothing. So, the problem is not Grayson hobbys shafts, it's a bent bell top.I believe the weak link here is that the top of the bell only has 3 instead of 4 support arms? on the top of the bell, making it eeaasy to bend. Upon close inspection, my bent one even showed the wrinkle lines of compression.
Now I wonder if I can beat the bent can back into line??
