Access ports in s/s water tanks - best way?
You could do the same thing as the aluminum tanks but instead of threading
the bolt down you could thread the bolt up from inside the tank and locktite them as to give you studs from the outside of the tank. I understand the tank is thin but the threading would only have to hold the bolt in place from underneath while you put a nut on. Pop rivets would most likely leak. Can you buy a plastic flange and cover from maybe Ronco-Plastics? Don't put aluminum in there if you don't have to. Phil "NT" wrote in message ... I want to cut access ports into the top of 2 s/s water tanks. I did this a while ago on my alum diesel tanks and it was easy to put covers back on the cutouts - the alum is 1/4" thick and takes a 1/4" fine thread easily with bolts every 2 inches and a 1/8" neoprene rubber gasket. The s/s is thinner and won't hold a bolt. I'm thinking of using s/s pop rivets to hold a 1/4" alum collar with 1/4" fine threaded holes in the collar around the cutouts in the s/s tanks - and using 1/4" alum plate covers again. Or I could use s/s plates held in with alum pop rivets and drill them out when I want to gain access again in another 5 or 10 years. The tanks are 25 years old and have not had access before - but we're very careful what we put in them - so this is not a frequent event. Any other good options? |

Good idea, but I'd also use a hacksaw to cut a screw driver slot on the end
of the bolt to help the locktite hold the bolt from turning, especially when opening the tank later. "Phil" wrote in message m...
