Nice craftsmanship. Good job on building your sump. Did you use the pins method or just lay the pieces together and glue them? What did you use for weights? Usually I'll use some bricks wrapped in duct tape. When building small sumps out of quarter inch acrylic I find it easier to place a large sheet of cardboard on the table first to act as a cushion. I also like to keep a bowl of pennies around to wedge under the joints where needed to help hold the seams together unitl dry. You said that you used WeldOn 14 right? Do they still make WeldOn #4? I bought a ton of WeldOn 4 a few years back to keep on hand and haven't ordered any in a while. Anyways, Thanks for sharing your project with us. I look forward to seeing more of your handywork.
yeah you can still get weld-on # 3,4,16,10 and 40.
and myself I use clamps I have clamp that will expand up to 8' if needed, and clearance of up to 32".
later I'll post my bubble trap media box my effluent box and my stand I made.
