When we set up each side, we used the squares taped to the piece of acrylic laying horizontally:
We used the pins method. I used standard sewing pins, but I also like the idea of using guitar strings. These pins may have been a little bit too big, because the Weld On would really squirt in there if I wasn't careful.
We used the square setup, gluing both sides to the back panel. We held them in place for about 5 minutes, and then let them stang for another 15-20 minutes. We then placed the front panel on the table, and glues the sides to it. Here's a pic of the tank before we put the top and bottom on:
Finally, we glues the top and bottom on. It took me, my dad, my mom and my wife to hold all of the corners in place, and to pull the pins. There is probably a better way, but we got the job done nonetheless. Now, the finished box is sitting with bricks adding some weight to cure for about 48 hours:
Everything worked out pretty well. There are a few bubbles in each of the seams, but not enough to cause problems I hope. I suppose we will find out when we do a water test on Tuesday after we route the top to create the euro brace.
What is the secret to perfect, bubble free seams?
