Wouldn't it bend like a banana as soon as he milled one cold rolled side off
Rolled steel will bend if you cut one of the rolled faces off (the stress in the remaining face will no longer be balanced out by the missing side) Mr McSpank would be milling off the edge only so, no serious bend problem.

I'm guessing 35 pence each to get laser cut, would you piss about making one of these for 35 pence ?
I wasn't suggesting "pissing about" making a 100 off on a mill. Hank only wants a couple to prototype his geetah pick-up
