Starting up!

Hello!

When starting for the first time it is natural to be a little scared, I think of two concerns:

1. I am afraid it will blow up! Dont worry it wont do that!

2. I am afraid it wont work! Dont worry it works, but it may take some time to get it working with full potential!

So put it in the water and "do it"

Like polishing shoes

Slovenia
Remember the old days,, in the city they had the guys on the sidewalk that Buffed your shoes.
The way I set up the can [unopened and filled] in the vise its just like polishing...
the sanding belt removes material at crazy speed as you Buff away!!

The only reason I sanded thru was the can has small imperfections below the "grade" that I was trying to remove [small paint specs].

Once you have everything set up this goes quick .. rings are a pain but still no more then ten minutes ,then I just stretch to the Gap size!! [not to easy].

Tomorrow is gonna be a big day for testing [hope I sleep tonight]
I think I'll go for the ikea too...........
Start Nice and early ,Lets see what these babies can Do??

This is the first time in months I actually have some down time [and I'm working] weird ,but the owner here spends 10-12 thousand a month to heat theses buildings
during the winter months ...and as I told you before they help kids and young adults get there lives back ...and way to often he just ends up not even charging....
Good people here ,the kind of people this world needs more of !

I hope this works they'll be able to help a lot more people!!

Thanks
Chet

Sweet!!!

Very good idea Ahura!!! Thanks for sharing that. It was such a simple remedy I didn't even think of it. Elementary my Dear Watson as Sherlock Holmes would have said. Good Show!!

To save your can from crushing when you want to sand it, before removing the top, fill full of water and put in freezer and when water is turned to ice you can sand the can in peace.

65mm Diameter Beer Cans

Hi Chet,

Sorry, I wasn't sure if you planned on firing the can up with the top still in place or not. I knew you'd at least have the contents drained out. That's the best sand job I've ever seen on one of these cans. The material on the sides of the cans is so thin, it's just a real pain to sand them empty. I was bending and kinking my first cans until I started supporting the area from inside the can where I was going to sand it on the outside. I have a special setup now I put in my vice and it works very well. It's kind of like a round anvil that fits inside the can just beneath the area you are sanding. I just keep turning the can with my left hand as I sand with my right so that I'm saning the whole can as evenly as possible.

I recall somewhere in my notes where Mr. "C" said that 65mm diameter was the optimal diameter for this boiler. That figured out mathmatically somehow for a quarter wave if I remember right. Anyway, I think he figured the 2.52mm gap for our specific mains in USA. I think that gap was for 220 volts to but it may not make that much difference because I think the frequency is the same for 110 even though the 220 is more efficient I do believe.

Anyway, for now I'd just use the 2.52mm gap with the wide can you are using now. I think the can for that tall energy drink I recommended some time back will fit the bill with a diameter very close to 65mm. I think that energy drink can was a lot thinner than the Arizona iced tea can. We'll have to ask our buddy about that who's tuning those energy drink cans.

I'll keep getting information as I can.

Slovenia, No
I wanted to finish all my sanding before I emptied the can and cut off the top!
I'm running this facility tonight so I can't work out in the shop
{in case of emergencies I have to be available ={ ]
You would not believe what kind of things can pop up in this place ,huge responsibility !!!

I think once the Chef is done in the kitchen tonight I'll go in there and fire up the Savic Boiler! [real responsible HUH?? !=.]

BTW
S
You realize I am most likely running the wrong gap ?
Professor Savic calculated for a 65 MM European can at 60 HZ Its 2.52
As I posted above my Can is 73MM, it would surprise me if its still 2.52

Perhaps he didn't see my post ? maybe he can give me the gap? this is the biggest can available here in the US [and cheap .99]

At this point any Data is good data ,[since we have none]
And I am anxious to get this thing Wet [and sparky]

Chet
PS
I see Ahura 's comment on freezing ,I actually had very good success just leaving it Full ,and this way when I sanded to much it let me know By peeing on my Leg!

PPS
To be honest fellows.. I really can't take a chance tonight ,I have to be available ,But tomorrow the day is much more open [like today] I have help coming in the AM!!

Besides I don't want to rush it And maybe the professor can give us the proper Gap?? Please?

Top of The Can

Hi Chet,

Are you going to leave the top of the can on your experimental can? I was just wondering. Thanks.

Fun Running

You'll have fun putting the power to it. Even without mine being tuned it worked very well. It's a very interesting heater.

The emery started getting wet,then I noticed My Pants were getting wet,
Then I saw an ittsy bittsy stream of water coming from a pin hole in the can!

So I'm done sanding and the can is now empty ,it feels like its made of Paper,so thin!!!!!

Should vibrate quite well!

May have over sanded a bit

Tapering The Can

Mr. "C" made reference to tapering the can again. He said you need to use as fine a sand paper as you can get and hand polish the can until it is fine tuned to the proper frequency. He said it took him two weeks to hand sand one of his cans. He said he spent two hours a day sanding tapering it with the finest sand paper he could get. He said it's very hard indeed to get it tuned just right but that when you do it is a very efficient boiler.

Very Cool!!

Hi Chet,

Wow, very innovative ideas. Very interesting test setup indeed.

Gaps!!

Mr. "C" says that for an efficient sonic boiler his recommendations for the gap need to be followed, (i.e.: 2.1mm for Europe, & 2.52mm for USA).

He said also that if the cans are not tuned properly that the results are not going to be so good. He said the US can needs to be tuned to exactly 60 Hz while the European can needs to be tuned to exactly 50 Hz. According to him, if your can is not tuned properly you are going to have a very inefficient sonic boiler. There you have it.
