Ok after a slow day at work I think I have found everything I need to coplete this project minus the aluminum sheeting my friend will have. Attachment 7621
one female aluminum 10" pipe fitting Attachment 7622
two male 10" aluminum pipe fittings. one to be capped and one for toilet seat... Attachment 7623
one latch to attach the two... Attachment 7624
and one ajustable pressure release valve... all for around $100 plus a toilet seat... might get a nice foam padded one... let me know if I forgot anything, if you think this should work, or if I have seriously overlooked something...
