Dave... The cart exceeded all my expectations, it is extremely strongly made. I am going to throw away my Office Depot folding table and replace it with this cart. The top shelf is made with 1/4" steel sheet, the bottom shelf with 1/8" steel sheet. The casters are not ideal, though they work, I may replace them with 5"-6" casters. The welds holding the old casters would need to be ground away. I would say it weighs about 300 lbs. With better casters, it will move better and could take 2,000 lbs easily, in my estimation. Maybe more, I cannot say. I am very happy with it.
The cabinets are also very decent and very deep. if you are local (I forgot if you mentioned where you are) you could buy them from me for a discount to prevailing prices, whatever they are.
As far as graphite goes, it is a lot of pieces that look like they were never submerged in oil and frankly do not look "used", though I do not know what the telltale signs of having been "used" are. Maybe
200 lbs of various shaped pieces, mostly rectangular.
I also had to pick a lot of garbage and some lots were big disappointments.
