    Anyone come up with an idea of how to keep the tuning port accessible without flares? I am using a six inch port for the Sonosub I am building. Open to suggestions.

    If you have a router, you can make a circle jig to cut the holes just the right diameter so you have to hammer the port it place. It should hold without glue, then if you need to mess with it, it should come out with a little tugging on it. I do that with all my ports.

    What do you mean by "accessible"? So you can change it later if needed? I believe you'd have to cut off the end cap to get to the port once it's all sealed up. "Mr. Patrick Sun, if you please, sir" had to cut off the end cap of his Sunosub II to replace 3 4" ports with 1 6" port.

    No ideas about how to avoid this. Sorry. Anyone else??

    Casey,

    Here's how you can do it. When you make the top cap for your sub, cut a step in the cap that is 2" bigger diameter than your port and 3/4" deep. Mount the port on a plate that is 2" bigger diameter than the port itself and 3/4" thick. Screw the port/plate assy to the top cap with at least 8 screws and use foam weatherstriping to ensure a good seal with the cap. If you have a circle jig and a router this should be a piece of cake to make up. You can make up several different plate/port assy with longer/shorter ports to get the tune you want.

    Let me know if this is not clear enough.

    Good luck,



    Chris

    I've considered something similar for experimenting, Chris, so your genius is appreciated. [​IMG]
