So, I was reading(like that is hardly believable, but it is true) this thread about a DIY internal canister filter... and I was wondering why not an external one... so... I wrote down some notes, a few fatal mistakes and a full recycle can later... I have it down to a seal-able bucket with metal ring and a few wing nuts sealing it all together... and then I ran into a problem, how the heck should I make the hose connectors able to swivel?
