Mark 48: Torpedo in the Water!

February 20, 2018 · in Ships · · 11 Comments

I have been involved in consignment builds for a long time now. I tell my customers I will build them anything from Autos to Planes, as long as I can find it in kit form. One customer who had asked me to build every plane he had contact with in his USMC service had a unique request. After his USMC service he became an engineer for DOD working on the Mk.48 US Navy Torpedo. So I got this unique request..."Can you also make me a Mk. 48 Torpedo"? Well, I thought, I am not sure if there is a kit of a Mk.48 Torpedo? He said "Come on you can do it!" So I could not resist his challenge. 1st I thought I could scratch-build one based on its basic shapes...tubes, a prop, etc. Or, can I shape it from wood? I don't have access to a lathe, not am I experienced in working with wood. So I just kept on searching the net looking for Mk.48s. Lot's of pictures but no torpedo kits other then small scale versions that you would hang on a 1/72 aircraft, or 1/350 sub model. Way to small! I found a desk model of one on Ebay made from wood but my customer thought it to pricey for what he saw in the add. It looked like a mono-chromatic painted wood model on a stand. One day I hit on a 1/72 version on a 3-D printing vendor website "shapeways". It was not overly detailed but the shape was right, but way to small for a desktop model. I had never ever worked with anything from a 3-D printer and it was not cheap considering the small size and lack of detail. Also if you selected the higher quality material it was even most costly. The material was advertised as smooth, glass like. So I tracked down the owner of the 3-D design being posted on this site. I asked him if he could scale up his 1 72 Mk.48 posted design. He responded with a "yes" and a price quote. It was pricey and as a result I did not select the most expensive material b/c based on material description I did think I needed it. I thought I could just sand it smooth. SO I ordered it and it came quickly. Shape was good, but very rough material...not smooth as advertised. I tried for days to sand it but it was so solid and material was hard and not sand-able. I contacted SHipways and expressed my concern. They responded quickly and refunded my cost allowing me to upgrade to better material. This arrived quickly and was much better. Not perfect but I could sand it better. After doing some more research on colors and details I was off to the workbench to build a Mk.48. I had to do some creative and advanced paint work to make it look realistic, metallic, and not mono-chromatic and toy-like. I needed to modify and add to the prop nozzle at the rear. I also needed to add some surface detail, such as scribed lines to indicate different sections of the body. This was a challenge but after some requests for help from my friends on the Facebook model groups I choose the "Pipe-Cutter" as a scribing tool and it worked perfectly. So, now you have it. A 1/32 Mk.48 Torpedo in active, armed, service colors. I know it may not float your boat but I thought it to be unique and weird enough to post. As well as, I learned a lot from the experience and wanted to share the 3-D printing experience with you, my fellow modelers. Comments welcomed. I hope you enjoy it!

  1. Nice result...looks like a torpedo to ME (although I'd never have suspected it would've been that color). So - what were the two "materials" you mentioned?

    • Its really hard for me to describe the material. One was a sort of hard fiber rubbery material that had a rough surface. The other was less rubbery, more hard and smooth not needing a lot of sanding. If u go to the Shapeway site it will give a better description of material.

  2. Hey - a model is a model! Nice - and I'm with Craig - what's with the pea green? - looks like an AMC Gremlin that still haunts my nightmares sometimes...!

  3. Great job, and something different!

  4. Great work, it almost looks as if you could smoke it.

  5. Now that's something you don't see every day. Looks good Paul.

  6. Interesting and VERY different!

  7. I am actually looking for a torpedo model. I have a US Navy torpedoman friend retiring soon and saw your model. I worked with this torpedo for 28 years and your model is accurate. The colors are correct and the yellow which represents high explosive is an awesome detail.

    • I built that for an Engineer who worked on them for years. It was the strangest request I had as a model maker. I used a primative 3D printer model as the basic model then detailed it a bit. The model was purchased from Marketplace on Shipways Vendor site. I am happy u like it. Took a lot of research to get the colors correct.
