    Measuring Tools

    Measuring tools work great Chet. I never had any of those before.

    Making Ring Method

    I found a better way to make the ring too. I marked my 90 degree ends where I needed to first on both ends of my 5mm iron strip. Allow at least 3/4" of material for handle on both ends of ring. I also added an extra 3/4" of material on one end which I folded over to hold my other end in place. I got two sets of vice grips after scribing my bend areas. Put my iron strip around an iron fence post and attached a set of vice grips on each end of the steel strip. I now pull my vice grips under tension with the steel strip against the fence post back and forth at least ten times. This will put a radius on your strip and also take all the warping out of it at the same time. Now detach your vice grips and bend your 90 degree angles and put your ring together. It works really well especially if you left a tab on the end of one of your handles to fold back over the other handle as a keeper. Let me know if you like it.

    My camera battery is down so I can't show you a pick right now.

    Ring Anchor

    I figured out a better way to anchor the ring to the side of the container. The ring material being as thin as it is and the width what it is needed a completely upgraded anchoring device.

    Ring Holder Method (NEW)
    A threaded 3/8" rod with a small slot in the end to accept the handle on the ring. There is a set screw that screws down through the slotted side of the threaded rod wedging the arm of the ring against the opposing side of the slot.

    Ring of Iron

    Mr. "C" did say we needed a ring of iron referring to the negative ring in our assembly. The dimensions he called for were .2mm thickness and 5mm width.

    Tin Can Thickness = .1mm

    If you try to fold it over in a vice, you warp it really bad. Also, it's hard to fold it 100% straight when all you have is just a small vice. If someone had a brake, they could fold a piece of this can properly very easily as well as cutting it off perfectly flat without warping the metal like a pair of tin snips has the ability to do.

    Anyway, we're on it now trying to ascertain the best way to go. The .1mm tin can material is a lot more rigid than the aluminum can material which is .2mm.

    Cutting a 5mm strip of this can material is quite fun too. I've cut four pieces and can't get any of them to come out exactly 5mm. They are all either a little below 5mm or a little above but no cigar yet. I'm using tin snips and sighting down a scratch line on my tin material.

    Thanks for catching that .2mm thickness mistake in my pdf file Chet. I don't know how I made that boo boo but it was a really bad one.

    PDF File

    Updated & Corrected information on the ring thickness. Changed from .5mm to the correct thickness of .2mm.

    .2mm correct thickness of ring material

    Can Mounting Scenario

    Hi Boguslaw,

    Yes, in the original diagram I received from Mr. "C", it shows a very serious base attached to the bottom of the can for anchoring and also as an insulator to keep the can away from the side of the reservoir. A hole must be drilled exactly through the bottom of the can. The can base needs to be kept away from any surface that would deaden it's vibration. The walls of the can must be allowed to vibrate their whole length without any hindrance. So, my two cans connected together probably will not work well.

    Mr. "C" didn't say what material to use to mount either the ring or the can and/or how to specifically mount them. I think he wanted to see what I'd come up with, but I think it's important to do it right and I'm not sure if I am doing it right.

    Mr. "C" said that the can needed to be tuned and not the ring but that if the can was tuned properly and the ring made properly that the negative ring would make the can sing @ 400 Hz for European 220 volts and 300 Hz for USA's 115 volts.

    Best Regards,
    Slovenia

    How the can should be mounted on outside container ? Beer can has concave bottom , does it have to be punched in the center and mounted on SS rod without edges of bottom contacting outer container ? The more stable way would be using SS rod but also with edges of bottom supported on outside container wall (of course using some rubber insulator between).

    If you design yourself a variable frequency powersupply ( preferabely variable voltage too ) you will find tuning will be easier. I think this is why Meyer was using a car alternator to run his cells.

    Coincidentally

    Coincidentally, the thickness of the aluminum beer can and/or coke can is .2mm thick. So, why not use it instead? The tin can would of course be a little more rigid. I'll take the specs on the can in the morning.

    Actually Better S

    .2mm is closer to tin can specs
    Plus Chester can Tune it [to size] with the Plating machine!!
    So Can you S if it becomes Necesary![Its easy]
    Sweet!!
    VERY SWEET!!


    Thanks
    Chet

    Ring Thickness Query

    Well guys I screwed up. The thickness of the ring material is supposed to be .2mm after all. The .5mm thickness was a mistake.

    So, go with the .2mm thickness for your ring!!

    Well you really don't need Titanium to store steam?
    But who Knows ?
    I'm sure once we get a test going we'll learn a lot more!!
    Would really be nice to be where Core is at right now!!

    Tin Cans

    The tin from tin cans is most easy to work with. The stainless is a real pain. So, for a prototype, I'd just use tin can material for the ring and rivet the parts together with stainless rivets. Later when we have a good working proof of concept device we can worry about longevity and using better materials.

    Most guys would not want the pain of working with the stainless. I should have stayed with the tin for now but didn't.

    Wow, interesting. Good job Tektron.

    Thanks (Ring Material & Thickness)

    Hi Chet,

    Yes, I saw the different thickness scenario today too. I'll have to go back into my correspondence with Mr. "C". I think it's .5mm and that the .2mm was a typo, but I could very well be wrong about that. I don't remember the .2mm thickness being mentioned by Mr. "C", so it's probably an error. I'll get back with everyone about that.

    Ring Material
    He doesn't mention which material would be preferable for the boiler we're working on. He does say he needs titanium for his newer more complicated patent version. So, maybe titanium is the best choice but it's also harder than you know what. So, it wouldn't be my choice. You have to cut it and drilling titanium is no easy task. It's one of the hardest substances out there.

    Best Regards,
    Slovenia

    Have you Micced any tin cans??

    S
    You have two different sizes fro the ring thickness

    Negative Ring Electrode
    Ring Width: 5mm
    Ring Thickness: .2mm

    And right above its .5MM thick?
