So far, no, but I have on some of my vintage wood working machines. Finding or making places to attach the ground wire is the hardest part on those. I usually end up drilling and tapping at least a couple screw holes to attach the grounds on them. I don't like wires to show more than necessary so keeping the extra ground lugs out of sight is important to me.
I think the biggest challenge for you given the sizes of the wire (large compared to 2 conductor wire) and parts involved (small, so not much room for extra anything) will be doing a neat job of it.
