German S-100 Class Schnellboot (Fast Boat)

 

 

The SBoot Superstructure

 

The Schnellboot mid superstructure consists of a number of sections, mostly consisting of mushroom shaped Air vents for the massive supercharged diesel engines and a central duckboard circle for an Oerlikon 20mm canon.

This photo shows the mid section which has two elevated platforms with the long mushroom shaped air intake vents, one for each engine and located directly over the original boat engine locations.

The mushroom air vents are made using 1mm Scandinavian Birch, 3 Ply, material for everything except the mushroom curved top as it needs to bend over a small radius so I have cut it from 0.4mm Birch ply material. the ply needs to be soaked in hot water for a while to prevent it from splitting during the bending process.

I glued one side of the curved top first and let it dry overnight and then after applying glue I used the edge of the bench to bend the entire length at the same time.

Sometimes the CA glues have an issue if they are moved during the initial setting time and so it needed to be clamped while it sets properly.

This shows the last side of one of the vents being pushed against the edge of the bench.

This shows the top being glued, again using hand pressure and the edge of the bench.

This photo shows the mid gun deck duck boards, a bit of a chore pushing out all the laser cut spaces but it looks very cool!

This shows the underside of the mid gun deck, there are two layers glued together and the curved side pieces which sit over the deck.

 

Here I have shown the two top covers glued in place on the inside sides only, I left them to set overnight or they would pull away once they are bent.

This shows the fwd mid section raised deck with mushroom base supports in place and the locations for the duckboards and hatch shown etched into the deck.

I have added the mushroom bases.

The fwd mid raised deck with two mushroom vent ends and bases in place.

Here I have added the duckboard section and the hatch.

This picture shows one of the mushroom ends and the base supports attached to the aft mid section raised base.

 

This shows the aft mid section raised deck and the single mushroom vent base and both ends in place.

The rear raised deck or hatch cover is fairly simple and has a protected hatch, there are a number of circular pods mounted on the top which I have marked.

Aft view shows that the protected hatch is off centre to the port side.

This shows the underside of the rear raised deck section, because the rear corners are rounded it is difficult to make a deck upstand with the same curve so I decided to add a squared up rear edge so that the upstand can just be square.

This view shows my first cut at the square life raft, not happy with it yet.
