The additional weight is probably 25 to 30 pounds. There are about 9 sticks of 1/2 inch pvc at 1.6 pounds/stick. 7 to 8 feet of 1 inch and a foot of 1 1/2 inch. I screwed a lot of the fittings in instead of glueing them so I could take the frame apart in reusuable pieces if I ever wanted. Total empty weight is probably 70+ pounds. After thinking about it, I probably could have used 2mm coroplast instead of 4mm to save a bit of weight but I figured the 4mm would last longer.
