DIve helmet Title Instructables.jpg
Dive helmet144.jpg

I love the ocean. I can sit on the beach all day just watching the waves do their wavey thing. Sadly, I happen to live in the middle of the Canadian prairies. No ocean to watch here. But there's always the world of make-believe, and what better way to get in the ocean vibe than with an amazing deep sea diver costume. I created this costume pattern to try and recreate the feel of the classic "Mark V" dive helmet which has become an iconic image of divers and the sea. It was used by the U.S. Navy from 1916 until 1984! Let's make one of our own.

Here are the tools and materials I used:

  • Pattern: I used the one that I created. You can find it on my website. It includes an adult and a child size.
  • 5-8 mm thick EVA foam: I used the foam from an anti-fatigue floor mat, but you can also use the less dense foam from a camping mat.
  • 2 mm EVA craft foam: One sheet is enough
  • Vinyl tubing: 3/8" outside diameter
  • Wingnut: 1
  • Super Glue
  • Hot Glue Gun: I love my glue gun because it is adjustable temperature. I like to use it at as low a temp as possible so that the glue cools quickly.
  • 6 & 8 mm leather punch
  • Cutting Surface
  • Gluing Surface: I absolutely love using a silicone baking sheet. Nothing sticks to it.
  • Sharp Knife: If it is not really sharp you will have a terrible time when you are cutting the foam. I like to use a scalpel.
  • Blowdryer: Used for heating the foam so it can be shaped.
  • Ballpoint Pen
  • Scissors
  • Paint: I used Liquitex Basics "Mars Black", Liquitex Basics "Bronze" and DecoArt Americana Decor Metallics “Vintage Brass
  • Rubber Gloves

Step 1: Safety First!

Picture of Safety First!

It's fun to get started, but you want to stay safe so that you can enjoy your amazing creation!

  • Wearing the dive helmet severely limits your vision. Be very aware of the activities you are taking part in so that you do not get into a dangerous situation. Children should always be supervised by an adult to ensure their safety.
  • Some EVA foam contains a chemical called formamide. There are some people that say there isn't enough formamide in EVA mats to be harmful, and others that say there is. Do your research and come to your own conclusions. At the least, I would say it is a good idea to open your foam mat up and let it sit in the sun for a day or two, as most of the chemical will off-gas from the foam. Or buy foam that is labelled formamide free.
  • Do not wear your helmet until all fumes from glue and foam are gone. The helmet is a fairly enclosed environment and you only have one set of lungs.
  • Do not block off the viewports with glass or plastic. These are open to allow proper airflow for breathing. Closing them could cause suffocation.
  • Sharp knives and hot glue can cause injury. Be sure to use in accordance with the manufacturer's instructions.

How did you know what to bend on the foam?
LostWax (author)  1234567guy6 months ago
Basically, you want to make the pieces more dome-like, so concentrate on stretching the centre of each piece.

HI, I made it 3 years ago, I do not have a completely finished picture but it was really exciting project to do.
Very nice work here, if I had more time I would buy the full templates collection.
Keep up the great work
Thanks

Nice work! I am impressed with the painting to give it a seaworn oxidized finish. I can also attest that hot glue is hazardous but probably worth the risk over using more toxic contact cement.
Wonderful job! Regarding the hazards of using hot glue, I always keep a small flat bottomed container with water, ice and a small cloth in it nearby so I can quickly cool down hot glue burns, helping to avoid painful burns and blisters.

That's one reason I love my glue gun with variable temp! I can turn it quite low so it doesn't burn me, with the other benefit being that I don't have to hold pieces together for as long while I wait for the glue to cool. Great idea keeping some icewater nearby:)

Thanks for a brilliant instructable and fun video. Voted! Some great tips in the video about assembling overlapping drawings and glueing EVA with glue gun. Regarding your pattern making, which software do you use?
LostWax (author)  hugheswho6 months ago
HI there! Thanks for the kind comment:) I currently use Affinity Designer for my pattern making. It's not perfect, but it does what I need it to (usually)
hugheswho LostWax6 months ago
Thanks for the reply. I was wondering if you used an unwrapping software like blender or pepakura, but it seems not.
LostWax (author)  hugheswho6 months ago
I played around a bit with Pepakura, but it always seemed to make things more complicated than I wanted them to be, so I just draft my patterns the old fashioned way. Lots of trial and error
