I'm building a diy skimmer and I had a few questions on how I could attach the cup to the main body. The top of the skimmer and the bottom of the cup both have a 1" lip that I want to put a gasket material in. What is the best material for that and where do you get it? Next I was thinking about using plastic screws every couple of inches but that would be a pain when I want to take it off. Is there any type of plastic clip or quick release mechanism that anyone has seen? Thanks.
