atic: 1:35 Bronco XXIII with interior

[DrSchmidt]

After finishing my VIIc build I decided that I need another cut-away challenge. So I'm going for a 1:35 XXIII boat based on the excellent Bronco kit. Minor problem....the model has no interior. So I'll make it myself. Started designing everything within the CAD, based on books, plans, and photos. Firts impression....drivetrain with stuffing box, thrust bearing, belt drive-coupled creeper motor, main clutch, e-motor, Diesel clutch and the MWM RS32S Diesel. Tedious, but the first fitting in the virtual pressure hull only required minor corrections. Good sign...

I'm so looking forward to this project, Doctor. Always good stuff from your work-bench.

Hull strcuture and electric switch panel done...getting cramped in there.

[DrSchmidt]

Oxygen bottles, compressed air bottle, Diesel exhaust valve, electric cooling water pump added...

[DrSchmidt]

Added the blower for the room ventilation. Here starts the guesswork because plans and descriptions are not clear about position and size. Also added the first sketch of the air induction and the air exhaust masts. Again, plans are not coherent...again, some room for guessing.

Again, plans are not coherent...again, some room for guessing and painfully slow reconstruction from some bad photos....nevertheless, getting there:

I found this photo

Maybe of help?

[DrSchmidt]

Awesome.....THX. That's U-Hai (S-170), an overhauled Nazi sub that was used as training boat for the post war German Navy....

The Diesel air-intake had been re-dedigned. So this might not be the actual XXIII configuration. But it gives good hints!

[DrSchmidt]

But actually, this photo helps allot understanding the drawings!! Tank you again.

The new photos of the induction masts booked me into a complete redesign of the masts and the respective piping. Again, allot of guessing, but the green pipes are according to the ventilation plan and comply with the pics...tedious.

Holy hell... This is going to be an amazing model, when completed, digital or otherwise!

[DrSchmidt]

The current status with added diesel airbox....

HOOOLLLEEE Mackarel!

More detail work. With the help of the iron plan of the Type XXIII I added the machine bases and floor. On the starboard side, benath the floor plates and parallel to the Diesel was the lubricating oil tank.

If you're planning on printing this, it'll probably pay you to buy your own printer with the price of them these days, versus bureau costs.
