atic: 1:35 Bronco XXIII with interior

That looks great. I so look forward to your posts on this.

Started with the structures below the control room floor. Blow the pressure hull of the control room were the two pressure tight regulating tanks. Within the pressure hull below the floor of the control room were a fresh an a waste water tank (latter in the front right in gray green). Between those tanks was storage space for ammo and equipment and the piping of the bilge pump. The intake filter of the bilge pump is the big cylinder in the front left. The color scheme is chosen according with the color regulations for German U-Boats of the Kriegsmarine from 1944, after which the space under the floor has to be painted in white gray (RL9002). I won't go overboard with weathering. None of the boats were old and the crew normally did a decent job maintaining them. Therefore a little filter, some washes and a hint of rust....nothing more.

I printed allot, most of the parts 3-5 times, adjusting strategy, orientation and parameters to get things right. From the final parts I started building a mock up. Got the see that there was still room for improvement, e.g. the volume shrink of the resin when cured allows for a little bit thicker walls of the structural parts which drastically increases the quality. All that culminated in the parts shown. This is going to be the control room that I'll put into the boat...probably ;-)

I don’t blame you - get it right! We will just drool and be envious.

After two weeks on holiday I'm printing around the clock. The large structural parts have thin walls and complex geometries. So it often takes several tries to get it right. But after two years of making the CAD models, I don't want to compromise the quality....more pictures soon.

Amazing work.

Absolutely amazed at the modeling skills. That by itself is a great skill. Then to actualize it by printing a while other level. Great job!!

[DrSchmidt]

Thanks Rob. Yes, I use resin printers. I have an Elegoo Mars and an Elegoo Saturn and use ABS-like Elegoo resin.

Andreas,

WOW! I am impressed!!

What type printer are you using! This almost has to be resin? This is going to be a masterpiece for sure!

Slow progress....printing large and thin structural parts is tricky an sometimes needs more than one try. But so far so good. Continuing with the control room and anything below, e.g. the piping for the bilge pump below the control room floorand the respective valves. All the pipes finally come together in the intake fllter of the bilge pump.


All that goes below the floor and is painted (accoding with UBoat paint schemes) in grey white:

The bigger printer is printing and it is printing fine. Got the bottom section done with the regulating cells and the space under the control room floor (fresh and waste water tanks, supplies and ammo storage). The floor with the bilge is done as well. Dry fiting looks promising.....

[DrSchmidt]

Kicked off and directly ran into some problems. During the print of the bottom section under the control room the LCD screen of my Elegoo Mars died.....shows in the print, obviously.



Good news is, that the print was good enough to test fit into the bronco hull....and it fits perfectly.



Consequences: visited the Amazonas an saw a special deal on an Elegoo Saturn and ordered it. Faster and more build volume. Will help positioning the big parts better for printing. The small one gets a new screen and then I'm all set for the next try tomorrow.

O.K., after I've wrapped up my Millenium falcon diorama, I'll start making the interior for my 1:35 Bronco XXIII. I'll start with the control room, as the periscope tube an the hatch for the conning tower provide exact positioning along the central axis of the boat. After that the torpedo room an machine room will follow. As a first step I divided the main structure of the control room into printable subassemblies and cleaned up remaining errors. Big parts...will be a challenge. Today I will put a new screen in the resin tank and get the first test going. Gonna be interesting....

[DrSchmidt]

Added the deep bilge pump, a double acting two cylinder piton pump, to the control room. Also some mor detail on the radio room (e.g. the curtain), the piping (e.g. the shut-off valves for the speaking tubes), cables and the engine telegraph next to the rudder control. fabrication wise I'm currently doing a star Wars Millenium Falcon and X-Wing diorama. But when that is done, I'll start printing an assembling tht stuff. goin to ne interesting ;-)

[DrSchmidt]

My pleasure....
