I have used all 1/2 inch CPVC pipe and fitting on the whole project. The sizes here will make a nice desktop Light Box, you can make it any size you want or need. Just remember you will need 2 pices the same size for the width and 2 of the same size for the depth. The 4 legs will all be the same. I did not use the cleaner on the pipe before I glued it, I just don’t plan on running any water thought it so I see no need for it. The glue holds just fine without it.
Cut all pieces that you need. After you have cut all your pipe pieces you will need to clean the burrs from the ends of each pipe. The inside is not important but the outside should be clean and free of burrs. Set them on end and check that all the pieces are the same length. If needed sand or file them to the correct length.
