Yup, file digs in unfortunately.
What did you use as a base for it? I was going to build a stack of 2X6's banded and screwed with a center cutout for the steel to rest in. Not sure how i can secure it down though.

Thanks! He's got 2 or 3 more lengths and some 3-4" thick rectangle cuts of the same material. Wonder if I should go back and grab one of those too.
