Iceman 29 Posted January 15, 2022 Share Posted January 15, 2022 A request from a Swiss friend. A Guppy kiosk conversion ( Porthmouth Sail version ) for a Gato Class submarine to represent the USS Torsk 423 with a 1:72 Gato Class Revell hull. I have to release the big sonar under the hull also. I found a lot of drawings on this excellent Gato Class website: http://www.gatosubs.com/mkptsail72draw.htm Unfortunately they are not very accurate, see picture, but they did help me a bit to start my 3D drawing. Luckily, you can find a lot of pictures of the USS Torsk in a dry dock during an interview and docked at the museum, especially on Flickr with HD pictures of individuals. This submarine kiosk looks simple in terms of shape, but it's quite the opposite. First sketchs: 14 Link to comment Share on other sites More sharing options...

Iceman 29 Posted June 24, 2022 Author Share Posted June 24, 2022 Resuming the 3D drawing on this project. 😜 I made a lot of progress today on the riveting and various sheet metal plates, the welds and the navigation lights. I'm already at 2150 pieces, with the rivets it goes up fast. Fortunately the documentation is very good. 6 Link to comment Share on other sites More sharing options...
Iceman 29 Posted June 27, 2022 Author Share Posted June 27, 2022 I still have a lot of stuff to add on the massif. Then I'll work on the "bathtub" at the top, periscopes, radar, schnorkel, etc.. There is no door on the port side, I will remove it. I've just mirrored the starboard side for now, there are some differences. 5 Link to comment Share on other sites More sharing options...
Iceman 29 Posted June 28, 2022 Author Share Posted June 28, 2022 The progress of the day, especially on the port side. I have some rivets to add, but I'll put them at the end of the drawing because the file has become obese and my Imac has a little trouble to follow. 7 Link to comment Share on other sites More sharing options...

Iceman 29 Posted June 29, 2022 Author Share Posted June 29, 2022 Tks Vincent. I tried oil-canning with a method I developed, not the one in the link above. It's quite tedious because each recess has to be drawn one by one, here there are few, the settings must be careful, too many, not enough. 🙄 It has the advantage of not being repetitive in terms of shape. 7 Link to comment Share on other sites More sharing options...

Iceman 29 Posted July 4, 2022 Author Share Posted July 4, 2022 Some additions and modifications to fit the reality on the port side. I actually separated the top of the sail from the bottom at the design level to lighten the struggling program. I'm going to tackle the top of the sail very soon. Then the two drawings/files will be merged for printing. I practice this way on my projects when it starts to drag. Although it's a submarine of the same class, the layout of the accessories on the top of the sail is different but the naming and shape is good. The thing with the fins is the Snorkel's exhaust outlet. The fresh air intake is just in front. SS 376 Mapiro / TCG Pirireis (S-343) In 1960, Mapiro was converted into a Fleet Snorkel submarine. On 18 March 1960 she was transferred on loan as part of the military assistance programme to Turkey . The Turkish Navy renamed her TCG Pirireis (S-343), after Piri Reis (c. 1465-1554), an Ottoman admiral and cartographer. She left San Francisco on 16 May 1960 for Istanbul via the Panama Canal, with her new Turkish crew. Pirireis arrived in Gölcük on 23 June 1960. She was commissioned into the Turkish Navy the next day. The submarine was removed from the US Naval Registry and sold directly to Turkey on 1 August 1973; she was scrapped by the Turkish Navy in 1973. I've moved on a bit on the top of the sail this evening. 8 Link to comment Share on other sites More sharing options...
Corsairfoxfouruncle Posted July 4, 2022 Share Posted July 4, 2022 (edited) Im always in awe of this kind of work, I only wish I had the skills and $ finances as their are plenty of things Id like to do.

Iceman 29 Posted July 5, 2022 Author Share Posted July 5, 2022 Thanks! 👍 Today's progress on the top of the sail. I have some modifications to apply on the front periscope n°1, for the rest it seems to hold the sea. The antenna with the bulb is probably a directional radio antenna, also used in aeronautics at the time. Personal photo taken at the RAF Tangmere Base Museum in England. The antenna can be seen mounted on a T6 in the background. 10 Link to comment Share on other sites More sharing options...
Iceman 29 Posted July 7, 2022 Author Share Posted July 7, 2022 I added some details. I reduced the surface of the fin. Then I started the test printing of the top of the sail without its accessories which will be printed separately. This part is tricky to print correctly. I am also printing it with 20 micron layers. Who will be the winner? 😜 7 Link to comment Share on other sites More sharing options...
ssn705 Posted July 8, 2022 Share Posted July 8, 2022 This is absolutely awesome. I cannot wait to see the results of the print. I vote for the tilted one as the winner. Dave 1 Link to comment Share on other sites More sharing options...
Iceman 29 Posted July 11, 2022 Author Share Posted July 11, 2022 Tks Dave and followers ! The prints went well. The top of the booth printed with an angle comes out the winner, but the horizontal one is not bad either, but you can see more the 20 micron layers. I'm looking for the camouflage measurement from the era that was prevalent for USN subs, year 50 to 70. AK proposes this: The museum photos give a slightly bluer gray if accurate.. So I have a doubt. RC258 Dark Sea Blue RC220 Light Gull Grey FS 16440 RC222 Insignia White FS 17875 RC231 Field Green FS 34097 Advances on 3D printing: I have the #2 periscopes to reprint, with a bigger internal hole, because it got clogged, so I can put a piano wire through it to prevent it from bending, which happens with this kind of resin part. For the periscope n°1, I was able to put the rod. It won't move anymore. I mount two of them. One for me, the one on the right, On the left you can see the parts that make up the top of the clump, I'll leave it to my friend Vincent to assemble it, it will be easier for the painting. 7 Link to comment Share on other sites More sharing options...
