Nice looking cart. I have a feeling your going to not like those castors! If you keep your shop floor clean then it probably will not matter at all. I would have used larger diameter castors so it will roll better when it's loaded down. I would never weld castors (I have in the past!), it always seems like the ones you weld on are the ones you have to replace! It's a nice looking cart; I'm not fond of the small castors.
