The coffee table assembly was not particularly difficult. I just cut the wood down to size and rounded the corners slightly. I then used a drill press to drill the appropriate holes. Of course, hole placement is very important so I used a jig to help with that.
I bought the 1/4" polished aluminum from a metal place on I-45 but I had to buy a 12 foot piece and cut it down. I used a hack saw which was a nice workout. Of course, I then assembled the piece and stained it but I couldn't get the stain off of the aluminum so I had to cut four more pieces to replace the ruined ones. Oh well, lesson learned and the finished product looks great.
