Thanks for this video! Just made me one from an old helmet that my son used to wore. It turned out great
I really enjoyed the video. Simple, strait to the point. As I was watching, I was thinking of changing my bungee on my XDeep….. which made me think : Inside the helmet where the knots are on the side and in the back… I would tend not to glue the inner padding where the knots are to allow changing the bungees incase it would be needed. Great job. Thanks!
I myself use my tactical bump helmet which I use for tac training there's no need to take off styrofoam and comes already with side rails and velcro patches so you can add lights or whatever you like using. You should try looking into using them I'm pretty sure you would like them. It's what works for me.
Great videos. So informative. Could you provide a link to the mesh helmet liner material? I cannot seem to find it.
Great video, helmet turned out great..
please, let us know the sizes. thx
Good morning. I saw your video and I would like to make the helmet too. I would like to know what material you used to make the padding after removing the original padding (polystyrene). Another question: how many lumens have the torches applied to the helmet?
Thank you.
thank you so much. what hood is this that you are using in this video?
Hi, i can't find the glue liquid Moly 8800?? Witch glue else i can use?? Very good video!! Thanks!!
hi, what is the thickness of the nylon mesh you are using?
really good video, i will try to do same ;)
This awesome. You should sell kits to make this stuff ;).
One idea: For removing styrofoam you can use acetone to melt it out. Of course it can be used only on shells from epoxy fiberglass and acetone resistant plastic. Ie. ABS plastic and holding straps may be unwantedly melted as well. It smell bad, but acetone do his job effortlessly. Especially for small residues of styrofoam it may help.
Yeah Acetone does react with Styrofoam quite intensely. A quick word of caution though that when melting Styrofoam with Acetone, you get a sloshy substance that is similar to Napalm, which is extremely flammable and the fire can't be extinguished with water. So if you do this, please make sure you have a fire blanket or similar close by.
And also vent the work space and clean the helmet properly afterwards.
what is inside your nylon ? where can i buy it?
nice
Hey Achim great video and very well explained. One quick question about the tension on the rear bungee. I agree that the bungee on your first helmet was a bit loose but I am considering having the rear bungee lying close to the helmet but not under tension.
Let's imagine the worst case scenario. You're in an overhead environment with low visibility and one hand on the guideline when you're primary light fails. Of course we should have the switch for the backup light facing outward but seeing as Murphy is our ever following dive buddy, the button faces towards the helmet we can't turn the light on without removing it.
Trying to one handedly unclip a boltsnap on a bungee that's under tension might be quite fidgety and frustrating.
Granted it's a very unlikely scenario but that would be my reasoning for cutting the bungee to length and not have it under tension. I would love to hear your feedback on this if it's a valid approach or creating hazards of it's own.
you are awesome mate..you are being my distance instructor!! good garage you have bro! i've seen so many videos from you.. writing to you from Spain. Where are you teaching/ living? germany..netherlands? wonderfull to see you on the videos! don't stop it..! all the best!!
Hi, thanks! I am in Germany - but ISE is available in Spain - have a look at the instructors List: is-expl.com/instructors
Hi Achim,
What kind of light do you attach to your helmet? Trying to build my own and looking for lights...
Hi, today I would use orca torches like we use them in the Alien Lights.
Does this two torches count in backup lights which are recommended besides main lamp?
Yes, why not?
what is a light's ?
Hi Joachim! Hammer Videos die Du da produzierst! Mein Respekt! Ich habe eine Frage, wo her bekomme ich dieses “Inner Lining”. Nach langem stöbern bin ich noch immer erfolglos. Hast Du da evtl nen Link oder nen Kontakt? Wäre sehr nett und mein Dank voraus. Gruß Marcus
Hi, Danke! das Zeug findest du im Matratzen Zubehör. das kommt unte rMatratzen damit das Luft zirkulieren kann. Gruss Achim
Thanks for this video.good afternoon. What material do you use to fill the helmet instead of the foam that comes from the factory?

também quero saber
What glue exactly do you use? I tried it with some silicon but nfortunately not with the desired result... thx
Hi Thomas, I used Sicaflex 251 which is used to glue car- un boatparts together - it sticks to EVERYTHING like hell and has about the same consistency as Silicone.
This is exactly what I was looking for. Actually I can find that exact helmet here in Malaysia too, it's the same helmet but different brands. OEM from China for sure :-)
Really interesting that you are using that nylon airy materials to line the helmet, one question, when air is expelled from the regulator, some air might creep inside the helmet, can the air escape through the nylon material, or is it an idea to cut holes through the lining to match the top holes in the helmet to let the air escape?
Hi Henrik, The air goes through this material without any problems - no need to cut extra holes.
Great! I managed to find a perfect helmet, however finding the woven nylon liner seems impossible in this region. Are you able to elaborate or find a link to something similar perhaps? In which country did you buy yours?
Hi Henrik, The material is called "3D-Abstandsgewirke" in Germany. If you google that you will get a lot of hits also from Amazon for example. I did not succeed in finding out what the english term for this is - mayba a native speaker can help us here.
It is either called 3D upholstery spacer fabric or spacer mesh fabric. I am wondering how think is the spacer fabric you are using in the video. Most I could find online is 3mm.
Hi Achim. I am also in Asia (Japan;) I googled Amazon (US and Japan) and cannot find the same material you have there. I tried what you wrote, then 3D upholstery spacer fabric, etc. Nothing like yours. Most of the materials seem flimsy or without holes, etc. Why not just use the inner cradle of a cheap construction helmet which can be screwed into a sports helmet easily? Those cheap helmets can be found on Amazon for a few dollars US? I just remove the cradles and put that into a cheap basic sports helmet? Still, all your videos are very helpful and enjoyable. Well done!
can you post the name of the helmet that you bought please, so I could find one?
Hi Wayne, I need to go and have a look, but it was a regular skater helmet from a local sports store.
What is this mat and where to buy it? In a gardening shop or more metal shop?
Because I have the same problem that the helmet is too big.
Hi, in germany the material is sold as "3D-Abstandsgewirke" I think in other countries you find it as 3D Liner, it is used under the matraze so air can circulate.
Mich würde noch interessieren, wo du das Gewirke gekauft hast. Grüße aus Augsburg
Looks like I can find it on the states as spacer fabric.
hi , what was the bungee cord diameter ? thank you.
Hi. The bungee is 5mm.
thank you sir.
Why not have the knots outside the helmet?
Can you use acetone to remove the styrofoam faster ?
Hi, you can for sure but I would not recommend it as the fumes that evelop are REALLY poisonous
styrofoam with fuel oil it makes black smoke, but with acetone all you risk is breathing a bit of solvant (AFAIK / am no chemist ).
Yes - it´s actually thoses fumes I´d try to avoid .-)
The new helmet is by far not as good as the old one. With no run-faster-stripes you will always dive last ;))
Why not just buy a helmet that is specifically made for cave diving?
Because a "helmet that is specifically made for cave diving" will still probably need adjustments (like setting up a light mounting bracket) and will cost 2 or 3 times more.
For some people the dive helmets like the Light Monkey are too small.
