Fictional Large coastal SSK

Milling the floodholes on the upper deck...

No one?

Newly made driveshaft is in ( for threaded props, anyone else making them from stainless steel rod via drill press, too?) and i made a more practical approach for the push rods for easier access and installation. The stern is almost done. Made a rough test and lifted the vessel at the sail and nothing broke. Everything is rather tough.
Need to take pictures.
Curious how that boat will handle with the large planes and the fat engine. I haven't weighed it yet, but presume to be at 10Kg empty hull weight, yet i'll aim for a low freeboard.

Hello everyone! I removed a bellow seal for the pushrods yesterday and to my surprise, it stuck to the brass tube i installed it onto plus the lid to the pushrod had gotten soft and showed a fissure. Somekind alike those silicone soft touch coatings on keyboards etc that turn sticky after a few years or when permanently exposed to sunlight.

I had not applied any grease/glue/alcohol, i only srt it up for testing back in '24 and removed it now. Boat was not in the water yet.

With that setback, and since i NEVER EVER experienced a bellow seal intact in the first place i am unsure i can use them at all. Maybe i just bought garbage? Really thinking about switching for my usual Engel Seals...

Anybody having advice? What brand or vendor should i look for? How do i maintain those seals?

Best regards, Jörg

PS: still NO cracks, David, even after falling from the bench...

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.

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;-)
