Looks very good, but I think you are going to need a BIGGER cup.
What is the height of cone, and the neck diameter?
you are correct! I made the cup before any thing else then change my mind on the body so I will make another.
the cone is 8 1/2" diameter on the bottom and 3 1/2 on top 21" tall
it wont fit in my cabinet so I will be useing it on my frag / grow out tank in the basement when I get it all done, I just started this in my brain then made it, then measured sometimes that just don't work! LOL
Having a 3.5" neck is going to limit the amount of air you can put into the skimmer. Cone skimmers are in effect "all neck" as they produce VERY little turbulence.
Also, if you haven't glued anything up yet, then I might suggest a change in the bubble plate. For a cone skimmer, if you make a bubble ring, with an area in the middle for water to come back down you will further decrease turbulence. Check out the pictures of the Warner Marine K2, and the new ATI cone type skimmer, they both use this type of bubble plate.
I am guessing that a 5" neck might be more appropriate, and allow use of a better skimmer type pump. There is a Sicce 2500 up at the shop (Reef Paradise) if you want to put your hands on one to see size etc. There are Sedra skimmer pumps and also the new Sicce that might work out as well.
I would go for an Air draw of around 1000LPH of air to make a truly effective skimmer. This would be WAY to much for the current neck diameter though, at 3.5" it would be a foam cannon.

thanks, lots to think about! I can always cut this one down for a 5" neck then it would fit in my display tank.
I kind of put the cart in front of the horse but its been fun!
Great build!! When looking in to pumps..the sicce psk 2500 is a good reliable pump, but there is the new bubble blaster pump that looks to have better numbers?? Can't wait to see how this one works out.
Nice build. I'm currently working on a cone skimmer of my own. I started a thread, check it if you get a chance. How did you cut the grooves in the collection cup? Can't wait to see more.
sorry I havent looked at this thread in a little while. I have not done anything new to it lately. all the grooves where done on a bridgeport mill. most of the stuff was done on a mill or a lathe.
