DIY Acrylic Refugium Pinned Pieces

Stan Hauter
When you put the pieces together, there should be no visible gaps along the sealing edges. The reason for having flat, smooth surfaces is that when you bond the pieces together, you want to avoid having bubbles in the joint. When you apply the Weld-On #4, it will be sucked into the joint via capillary action. The Weld-On chemically "melts" the acrylic surfaces and then dries, welding the two pieces together. To assure complete distribution of the Weld-On between the two pieces of acrylic, we will be using ball head pins to create a uniform gap and masking tape to hold the pieces in place.

You will want to practice with scrap pieces of acrylic until you can bond acrylic with no bubbles and have the pieces exactly where you want them, before moving on to your refugium. Before assembling the pieces, fold the protective paper/plastic back about 1/2" from the bonding area and cut the paper/plastic off with a utility knife or razor blade. Insert 2 pins in the joint and tape the pieces together. Bond only joints which are flat. Do NOT attempt to bond vertical joints.

Here is an example of what your pieces should look like before applying the Weld-On. Note that the pieces are even on the ends and edges.
