[Briefly] Assembly took me about an hour and a half- the pieces are NOT symmetric and you need to follow along with the product manual to minimize how many pieces you install backwards or on the wrong spot. A power drill (with Phillips #2 bit) is absolutely necessary for assembly; the design drives screws directly into undersized metal holes. The only tapped portion of the frame are the four caster mounts. [Extended] In geometry class you should expect to encounter Euler’s formula for polyhedral, F + V = E + 2. The number of faces, plus corners is equal to the number of edges plus two. While assembling this box you will become intimately familiar with its consequences. The four edges running front to back are assembled from three pieces each to accommodate an adjustable depth. Two screws couple the front of the arm to the center, and another two couple the center to the back. 16 screws later and the bag seems as full as you started. Then, the vertical pillars are attached with a further two screws at each corner. 16 more screws, 32 in total. This bag only starts to show signs of use. The left and right sides are formed. The cross-bars are attached to link the two sides. A further two screws for each corner. 16 more, 48 in total. The bag remains about 3/4 full. Corner braces are now attached to firmly attach the cross bars to the sides forming the depth of the box. Four screws per brace, eight braces. 32 screws, 80 in total. The bag is still over half full. Finally, you can attach the top panel. Only 14 more screws needed. 94 Screws in Total. You find out that the top is only sized for one particular depth. Do you go back and fix this mistake, or can you finally start tightening all these screws?
