Fictional Large coastal SSK

I'll send a personal picture with all the cracks, O David my David!

Have faith!

No. Post 'em here, so everyone can learn. (Checking my blood-pressure... OH, MY!)

You're in for a nasty surprise once this multi-media model suffers the effects of rapid temperature change at the lake/pool.

The "Kort-Nozzle" propeller guard has been permanently clamped down on the lower stern keel with a clamp from stainless steel.

[JHapprich]

Installation of the pushrods for rudder and sternplanes. Two small openings in the lower stern cone will give acces to the setscrews for fine tuning.

[JHapprich]

Ready for glueing it all down! Resin filler will close the gaps afterwards, while the port and starbord covers will be removeable to access the stern's "skeleton"

[JHapprich]

Some more work...

Construction of the servo tray and milling an end cap for the keel:

[JHapprich]

Little time during the Easter weekend to spare for the hobby, but i made a support for the stern cone that will align dead center with the engine and the sternward portion of the split driveshaft. Leaves plenty of room for the servos while puttung the engine more to the back of the electronics tray.

[JHapprich]

Thank you, Rob! Will do. Certanly intersting if the 775' engine will break down the drive train and if the momentum will roll the boat! Maybe will see more progress tomorrow.

Jorg,

Your skills with working with so many different materials on your build is certainly evident! The finished boat will certainly be interesting to see. I like David, really enjoy seeing so many different type of tooling being applied on your build. Your photos are great, keep them coming!

Fair enough. We'll see.

Haha, it is supposed to have a "used" look.Its weld-glued pvc on pvc. Its resing and glass on resin and glass. I guess only place with possible cracking to be the bow sphere. That thing is held together with screws and bolts and rivets.

But yes, there are several materials involved, however there was no cracking in between minus 10 degrees and plus 30 degrees that i had outside during night and out in the sun.

We'll see. Thats a test ship, not a centerfold;-)

[He Who Shall Not Be Named]

There are so many different materials employed on the hull. This thing will crack like an egg as it cycles through hot and cold environments.

Greetings! It has been some time since my last post as the construction of our garage=lack of workshop and cold temperatures in our attic prevented me from model building. Yet there is some progress with the SSK: Deck installation done, diveplanes&rudder are installed, residual tape marks removed, drive shaft under construction, engine mount done, major filling done.

This evening i made the sealing disc that will a) hold an O-ring between itself and the outer face of the Bow bulkhead that seals the locking bolt radially and b) acts as a large washer to counter the force of the tightened locking bolt against the bulkhead. A second o-ring will sit between the disc and the smaller aluminum washer, beeing compressed when tightened. 1-2 large cylinder screws , threaded through the forward bulkhead to the inside will slide into corresponding holes in the tray bulkhead to prevent twisting of the frame when locking down the boat.
