It almost drove me nuts. I hated that crown.

You're not kidding!! I just did some sliding dovetails and it totally
screwed everything up for me. I can't tell you how ****ed off I am
about this. Wish I had started with aluminum to begin with.

I'm going to try and flatten it in the mill end at work, but if that
doesn't work it goes in the garbage and I'll get an aluminum one to
replace it.
