I have several MK10s to service. I have come across a few comments here and there such as: Remove the polished surface from the piston stem o-ring. Micro-mesh the piston hard seat. These comments were made as modifications to try. I don't know what they mean or what improvement these...

I just bought a pair of latex gloves to use with my dry suit. They are great gloves, but they are very slippery. Does anyone know of a good product to add grip to my gloves? I was thinking something like spray on PlastiDip but am open to other suggestions. Thanks!

Hello, after 2 abandoned years I want to dive my 20 years old TLS 350 again. After Covid I developed a latex allergy and so I quit my dry suit in favour of just warm water diving. But the cold waters are calling :wink: The suit fits well and is still tight. A new TLS would be around 3500 bucks...

Well, I do believe that this is the best place for this. I created a new Onshape cad file that I think you guys might like. Yep, another single tank adapter. HOWEVER there are a few things to note about this one. Firstly, This thing is BEEFY. I designed it in an effort to add more weight to the...

Here is a gas blending system for those of you that don’t want to build a permanent station at home. This was my last winter project, when I made a movable continuous blending station for Trimix for my small Coltri compressor. I want to use a simple rotameter-based system for blending because...

People have been making their own Optical Fiber Cables for years, and there are a number of posts on this topic. The good OEM/Retail optical fiber cables sell for about $90 per cable! And most people need two plus spares. It's ridiculous and offensive how expensive these are when we know where...

Background Hey there all. I've been diving for a bit over a year now and got my sidemount certification. I decided to buy a set of used Xstreams in good condition, because a friend (who has been servicing his own Poseidons for over a decade) convinced me that servicing is pretty straight...

I ran into some issues with wanting to move where my Nerd 2 was positioned relative to my eye, while still using the adjustable Revo mount. I created a 3d model of the original part then created 2 different sized extensions that add 10mm or 20mm to the original part. It does require a bit of...

E-mails or DM's have just gone out to the first batch of folks who have previously expressed an interest in learning scuba regulator repair and restoration. In seven small seminars, we've now graduated over fifty students from the US and all over the world, including Aruba, Australia, Brazil...

Several months ago, I wanted a serious cutting-device capable of easily handling rope, and ended up buying some 10-inch shears. (more info in this thread) The first sheath I made ended up looking like this, and worked quite well. Features include a 2-inch slot for webbing in the back, a...

I just got a few tanks back from hydro today. Inspired by a recent thread on tank whips and a post recommending phosphoric acid instead by @rjack321 (and confirmed by @rob.mwpropane ), I decided to give it a try. It seems that many people are using the mixture and proportions recommended in...

So my wife and I just did a dive in Maldives where we could have used some reef hooks. In researching to purchase some, we see doubles and singles but no dual singles. Any reason? Why couldn't we make a dual single (for portability and hooking angle variability plus the benefit of dual hook...

Hi Everyone! I'm new to diving but I'm very mechanically inclined and the thought of servicing and maintaining my own gear is very interesting to me. These older regulators were basically given to me and I'm having a tough time nailing down exactly the model of each to really search for parts...

Hello, years ago I did a CAD redesign of a single stage double hose regulator. The design is originally from Eckart Richter in 1965. I wanted to build it sometimes, but never got it realised. Recently reorganized all my computer files, I found it. Since the availability of original two-hose...

Hello, I recently picked up a tool named cable cutter in a local hw store. I liked the Idea of some heavy duty shears with a blunt tip and no outside blades. The blunt tip looks like a good scratching tool, too. The tool is claimed to be rust proof, but anyway I changed for a real stainless...

Hello DIYers! I’m recently certified, and quickly realizing that fashion isn’t usually a top deciding factor when it comes to scuba gear. A girl just wants to have well-fitting gear in a color that isn’t black or pink! I’m also very protective of our marine environment, and one of my first...

Hey, everyone. I picked up a set of RK3s in white a while back, and well as you can see in the picture they are fairly rough. I just want to clean them up and get them looking as good as I can, because I understand they will never look "brand new" again. I've tried the following to clean them...

I'm convinced of the benefit of analyzing tanks for O2 percentage and presence of CO (carbon monoxide). I was a kickstarter supporter of Cootwo, and still think it was a great concept and form factor. I was unhappy with the lack (and tone) of support from Divenav in the past. On my last dive...

hi guys can anyone tell me if the oceanic mako and apollo AV1 use the same propeller? if so, what is the rough diameter of it? Last one haha, what is the diameter of the blacktip propeller? essentially wondering if the mako/av1 propeller will fit in a blacktip shroud for a bit of a project I'm...

Hey there, does anyone know the part number of the Fischer male connector that plugs into the Shearwater Petrel 2 EXT? I am looking to make up a cable for a DIY project. Cheers, Pete
