1/700 USS Entemedor, SS-340 Balao class GUPPY 1b 3D printed Model Kit.

I happened upon a Silent Service Vet at a gas station in Altoona one afternoon not long ago. Bob Kirby joined the US Navy at 17 years young. He was an electrician's mate 2nd class.

He was generous enough to share a couple of photos of his boat. The first picture is his boat in her GUPPY1b configuration. These submarines were redesigned as hunter-killer subs. (SSK for sailors.) The second is USS Entemedor after her conversion to GUPPY II and transfer to the Turkish Navy.

Against my better judgement I ordered a kit from the Far East. First hint: This is NOT the Balao class USS Barbel SS-316. She was lost in February of 1945 near Palawan and would not have made it into the US Navy GUPPY program. Likewise, this model is also NOT USS Barbel II SS-580, the forerunner to nuclear powered Attack boats, or any of her diesel/electric sisters. This misnamed 1/700 kit does fill an interesting gap in 1/700 US Navy submarines from WWII through the 1950's. Kinda cool!

The bright salmon-colored 3D resin is brittle and does not sand easily. The detail is interesting, and does resemble Mr. Kirby's submarine. Not too many parts and seemingly accurate, simple instructions. For removal of the kit parts Dremel grinding is recommended. Snipping this stuff will fracture/splinter it.

Frame work and supports removed. USS Banana-dor? The waterline resin hull print is severely warped. No big deal. Run it under warm water and flatten the ol' Girl out, right?
WRONG!
20240818_113324.jpg
Here's why. Clever Chingada 3D printers made the model hollow. Everywhere there is a hull penetration or a limber hole, you can see into it or through it. Honestly, a really cool feature for a model sub in this scale, IF the friggin' hull is flat at the waterline!!
This also makes molding and resin casting near impossible because of all the air that will escape from the hull openings under pressure, ruining the RTV mold.

I ground holes in the underside of the hull and dripped Future into it. The Future ran from bow to stern inside the accursed, hollow warped hull. I hoped to seal all the holes from within. I'm considering chopping the bottom of the waterline hull out, installing brass tubing in the groove and heating/ bending this communist-made prick flat.

Option B: Use the kit Portsmouth sail to modify a Fujimi 1/700 Balao-class submarine model to make USS Entemedor, drop this $13.50 Chinese 3D turd in the burn trash and be a Happy Guy. The Fujimi kit would need the BQR-2 sonar transducer array up forward.

Option C: Fill, mold and cast the step sail. make as many GUPPY 1b conversion kits as I want.
Stay tuned for more exciting submarine model developments!

Oh, Hey. Don't buy this warped submarine model Turd from China. It's one thing to buy a cool looking 3D printed model kit. Assembling same is a VERY different proposition. I recall buying the inaccurate 3D printed 1/700 Calypso kit. Similar garbage.
 
There ya' go. Beat that turd into submission! I guess the hot water trick doesn't work on 3d printed stuff?

If it was printed solid, it might. The differing thicknesses of the internal/infernal structure means the hot water doesn't heat it uniformly.
The heated submarine model hull springs back to Banana in seconds. :ph:
Removing a great deal of the internal structure may do the trick. :bm:
A length of steel rod most certainly will! :bat
Thanks again for looking in on my Battle of the bitty bent Boat!

Since I had my "Submarine On", making the mold box for USS Clamagore/Tigerfish/Ronquil made sense. "The Gray Ghost of the Florida Coast" will retain her PUFFS sonar array. USS Tigerfish (Ice Station Zebra)/ USS Ronquil will be regular GUPPY IIb/III mod. US Navy waterline submarines.

There was a planned 1/700 1960's "Strike from the Sea" kit planned that would have had refueling submarines for Navy P6M-2 SeaMaster nuclear bombers, P5M-1 Marlin ASW flying boats and F2Y Sea Dart Jet fighter escorts, but we'll see how all that pans out.

Anyway, Thanks for looking in!
 
Greg sold me a little compressor when he moved to Dixie. I only used it for 9 years to pressurize my molds and castings. It has finally given up the ghost. It won't go over 40 psi anymore, and has a small leak in the tank seam. (Sob, sniff.) It was a brave little compressor and well loved by all the employees at TLAR Models and Eggknobs and Inksticks. It will live on at my buddy Tim's house, pumping up tires until the brave little compressor, compresses no more. ZORN!

Fear not! TLAR projects proceed with a newer, bigger air-squeezer. 5 RTV Molds were poured hours ago. USS Clamagore is among the newest molds. My "Strike From The Sea" '60's submarine and seaplane set continues to grow. USS Simon Lake's tool shed is among these.

See here the 18-hour result of the molds for parts for the Bluenose schooner kit and the Tool Shed for USS Simon Lake. Gasses formed after 12 hours under 60 psi causing this "muffin top" to the molds. 4 of five molds including the sub and the terminal cabin for the paddle steamer set did this. Usually 12 hours of pressure is enough to de-mold the Masters, then at 24 hours the molds are ready to cast. After 9 years, my procedures are sound and customarily produce quality molds.

I asked Reynolds Materials via email, how a guy can tell if the Moldmax 10 trial packs are old/unusable. These shipped from their Dallas location this time.

I don't remember seeing this kind of reaction before. Color me disappointed at least and furious at best. WEEKS/MONTHS were spent getting these detailed miniatures just so. It they are ruined, I shall be bitterly angry. :vmad:
 
Thanks Paul. There isn't much that can be done, except give up, or..........
Salvage efforts underway. A test mold has been made to try a different batch of Moldmax 10 out on. 48 hours from mix/pout RTV this batch of molds are still bubbly, sticky garbage.

She's a mess, but I extricated USS Clamagore from her pink, gooey tomb. USS Simon Lake's tool shed and the dickhead coins were rescued as well with only slight damage. I don't like to lose.

Wow, that is quite the muffin top! So weird that you had that kind of reaction. Some kind of contamination possibly???
