....I'm reworking mine currently. Some time back I converted it to a piston tank but have never really overcome the problem of the differential internal pressure. strengthened the screw joiner, did it in stainless etc but never really any good. About to retro fit a bayonet ring from Norbert Bruggen - this means removing the last 20mm of the internal tube from within the hull that has been built around it. This will be challenging...anybody else tried this? Can anybody confirm if this bayonet fitting will seal against the internal pressure change of a piston tank?
A big attraction of going this way is that the elimination of the screw joiner means the threaded rod can run out into the forward flood area ( suitably enclosed of course) this means the tank can be situated further forward which should make the boat dive more realistically....instead of that slightly stern down attitude that results with the tank positioned too far back.
the modelbrass deck is a beautiful thing but haven't seen much about them in a while. Soldering to it can produce some alarming warps...they go as the brass cools but try to keep the temp down.
