Built a grinder tree for the garage. Its not done yet. I plan to weld some tabs on the main leg to allow me to zip tie the power cords out of the way as well as mount a power strip that they all plug into. I will also fill the main leg (3x3) with some sand to give it some down low weight as well as cut down on harmonics. Then weld a cap on the top and paint it red.

Should work nice.. pull it out when I need it.. roll it back into the corner when I don't.
Will also round off these corners, just the right height that a little one would smack their head on it!
Grinders are just setting on there for now, need to go pickup some mounting hardware and drill holes.
