    "Right to Repair" - Potentially great news for DIY!

    Adam Smith was very much not a supporter of monopolies. Right to repair, if it is anything, is a facet of anti-trust.

    Is there a hydro requirement on bank cylinders?

    Interpretation Response | PHMSA Oh, I dunno, if you dispute someones position, you could do like, 1 Google search and read a DOT letter discussing when the hammer test is applicable. I suggest you go read all the relevant regs they cite if you want to dispute it.

    Are zipties used for diving gear just regular zip ties?

    You can get low profile zip ties, and a whole bunch of variants. The hardware stores don't carry them very often.

    Is there a hydro requirement on bank cylinders?

    (Clipped). 1. It's OSHA, or it's state counterpart that cares. If you are a business, you need to comply with applicable standards. That means hydro even if the cylinder is never transported. 2. If you are a private individual you can do whatever you want. Your own comfort with the liability...

    Is there a hydro requirement on bank cylinders?

    Well, if Compressed Gas Association Pamphlets C-6-1968 and C-8-1962 say that... then I guess so. But I don't have a copy of them and can't check. And I don't know why people think DOT cares, they wrote the spec they are not the tank police. OSHA are the ones who will get all bent out of shape...

    Fins more flexible than Mares Quattro?

    Force fins. I find the pockets to be fast more comfortable than most, but most people report they are much easier on the knees and joints in general.

    1st Dive Ever - Where in Maui?

    An extra vote for Molokini crater. It's a great first boat dive. The site is almost like a swimming pool, it's shallow, sheltered and full of life. It's also small and full of other drivers. Probably not a place that you will dive a bunch of times, but it felt like the kind of place you see...

    Picking up rocks and combing through seaweed?

    Veganism is it's own ball of wax... But there have been studies into the impact of red meat in terms of GHGE. Implications of Future US Diet Scenarios on Greenhouse Gas Emissions | Center for Sustainable Systems This one for example, that got a bit of adverse media attention recently...

    I take back every mean thing I’ve ever said about my LDS.

    Its bonkers. Given the amount of scratching on the window, I'm guessing either acrylic or polycarbonate. Either of which can be vacuum formed easily.

    Suit filed in case of "Girl dead, boy injured at Glacier National Park

    Ahem. As a private seller, no I didn't ask. But then he drove a tow-truck and had to tow the car away. When I worked at a Car Dealership that actually had enough money to get sued. We required a copy of your license, proof of insurance and that the car was taxed. And I told at least 1...

    Suit filed in case of "Girl dead, boy injured at Glacier National Park

    IANAL. But for this reason in California is normal for lawsuits to include 20-30 John Does. Just in case they need to add someone they find in discovery might be liable. Oh you sweet summer child. Please read about product liability, UL, CE, TUV etc etc etc... If you sell someone something...

    I take back every mean thing I’ve ever said about my LDS.

    I have a sneaking suspicion that the curves and radi'i are simple enough that you could press it with a relativity low force press. Well, I assume. I'm not actually a pressed metal engineer or anything. But those edges look fairly easy. I'd go chat to an engineer at MetalFX, they normally have...

    I take back every mean thing I’ve ever said about my LDS.

    I don't know how much force would be required to completely press the shape (removing the need for hammering)... Plus I've not actually seen a freedom plate in person so I have no idea what the edge geometry is. But hammer formed metalwork, using a buck or form goes back a long long way. You...

    I take back every mean thing I’ve ever said about my LDS.

    Casting the pressing tools. Casting the plates wouldn't make any sense at all. But the finished plate is a relatively low precision part and isn't from a particularly hard metal. So a cast iron press tool would make a lot of sense. Its not done that much any more because people are trying to get...

    I take back every mean thing I’ve ever said about my LDS.

    Thanks :) Its a gift. Although its mostly having the kind of brain that retains all of this stuff and having talked to a lot of skilled people over the years. That and having learnt from a bunch of mistakes! And happy if I can do anything to help a product move forward.

    I take back every mean thing I’ve ever said about my LDS.

    Absolutely. More 'bespoke' things like this is probably a great way for an LDS to keep the attention of divers who already have all the normal gear. Wood. For sand casting at least, the plugs are normally wood. You can do it with wax, but I don't think you need the fine detail that you get...

    I take back every mean thing I’ve ever said about my LDS.

    I don't think they had heard of it before, rather that they were excited at the idea. I have no idea if they are on Scubaboard, although I told them to look here if they wanted to know more. You should also talk to Universal Foundry Services in San Leandro, I know they do small volume and...

    I take back every mean thing I’ve ever said about my LDS.

    Reading your first post, I assumed you had been over to Cannery Row Aquatics. I was there a couple of weeks ago and mentioned the Freedom Plate, their eyes got big and they got all excited. Good luck with scaling up, I know there are good metal shops in the area, sadly I don't think there is...
