Max- i'm trying to get the bar as close to the floor as i can, but i can only go so far. I also don't particularly want to have to hammer the bar back into shape much. if i go for the 10mm stainless (and probably will anyway) i will go for a flat bar instead of the shaped one i have there
there will probably be skirts round the sides and a ground scraping wedge at the front to try and lure the real flat pushers up onto the bar.

thanks.
