Cheers VT.
I want to get them cut soon, as I'm trying for a strip & spirit run today.

I'm off into the shed and cut me some as soon as I can see what I'm doing.
Daft Q...how many "ring size" for a airstill??

About a "handful" should work fine.....

Equally possible that small coinage in Canada is still higher grade copper......

Yarg! I wonder if that bit of zinc is enough to impart off flavors? I may cut the pennies out of the equation after reading that. It makes me suspiscious of the settles I cut from heavy gauge copper wire, too... Is it an alloy? Is it coated with something industrial and nasty-tasting? Hrrrmmmm...

In sort of the same theme as "what's in your still," I was check a batch of cornmeal wash today and noticed a floating hunk. Actually it's been there from the beginning, but I thought it would eventually drop with the rest of the meal. Anyway, today I decided to break it up with the paddle - it wouldn't break. So I fished it out. Turns out it was the chunk of foam rubber they'd stuck in the bottom of the hydrometer's shipping tube. I'd wondered where that had disappeared to... heh Glad I didn't try to distill it!

Copper is expensive everywhere now.
Caught a price for scrap copper on TV last night of £5,000 a ton.
I was in a metal scrap-yard last year,and watched an International Shipping container being filled,weighed,and the padlocks photographed,before it left.
There is not enough copper in the world for China to wire it's homes as we do in the west.
I wait to see the solution to this.

In the meantime I save all copper offcuts and throw them in the boiler as boil pieces,despite having a copper head and long copper condenser.
And yes they come out dirty,so guess they are doing their part in catching sulphides.

Hi Cherry Yidaki,

Your penny idea peaked my interest so I went over to Wikipedia and came up with the following re penny composition:

1793–1796 100% copper 13.48
1796–1857 100% copper 10.89
1856–1864 88% copper, 12% nickel (also known as NS-12) 4.67
1864–1942 "bronze" (95% copper, 5% tin and zinc) 3.11
1943 zinc-coated steel (also known as 1943 steel cent) 2.67
1944–1946 "brass" (95% copper, 5% zinc) 3.11
1946–1962 "bronze" (95% copper, 5% tin and zinc)
1962–1981 "brass" (95% copper, 5% zinc)
1982 varies: "brass" (95% copper, 5% zinc) or copper-plated zinc (97.5% zinc, 2.5% copper)[6] 3.11 or 2.5
1983–present 97.5% zinc, 2.5% copper (core: 99.2% zinc, 0.8% copper; plating: pure copper)[7] 2.5

I'm an ex-pat now in New Zealand - so all my pennies got left behind - has to be copper pipe cutting for me - but it is so damn expensive over here - thats why I said I'll get a small elbow and cut it down to ring size.

All the best,

Mike P

I had the grandkids pick pennies out of the coin jar (pre-1980), then bend them in half with the vise in the garage. They work great and the kids had a blast doing them..Clean them up with vinegar and you're good to go.

Someone said the American pennies went to copper-washed zinc in 1981, so I double-checked the dates.

Thanks Aidanmac,

I'll buy a small copper elbow, cut it into 1/4 inch sections, then flatten them in a vice and drop them into the next air still distill. I have a copper mesh bit, would it be worthwhile putting that into the output flow of the air still or does it have to be in the distillation - steam end?

Icefever - yeah, there are tons of good nuggets of info in here, you just have to go searching through all the thread methodically. :-)

All the best,

Mike P

Just wondering if you had done any further testing on this cotton mesh-Air Still idea, since the last post here. Would be interested in your results if you had as I was thinking of playing with this a bit myself in my air still.

In the end I found that simple copper pipe cut offs, flattened with a pliers did a good job in the Airstill. In my 50lt keg the pot head and condenser are copper so I don't bother otherwise.

It will work a treat providing its pure copper also copper wire threaded throgh the condensor coil does a good job

They say there's no daft questions, but I may have one... what's wrong with just dropping a copper pan scourer into a airstill??? won't that work the same??

Hi spud if the 78-80 deg c is at the top of your column then thats spot on.as regard the copper scrubbers most shop bought ones are copper coated and not suitable,best way to tell is do a magnet test
cheers

I tried the copper scrubbers in a Rum run and I found that it tasted funny like something came off the scrubbers. I used store bought copper ones if that makes a difference. I now use a bundled lenght of copper electricians wire fashioned to go the full length od my collum it seems to work great.
I think this might be better in another thread but I am having problemswith high trmps on spirit runs. I ususlly do not grt any product ouy of the condenser until 78- 80 Degrees which by all accounts seems rarther high. the end result to me seems fine but it could always be better. Any hints would be appreciated. I'm useing a T500 and use both turbo and Rum and molasses washed but I find the Rum ones take awhile they are hard for them to ferment out. Feel free to pounce on my mistakes. Only way You can learn. Does anyway know what the cost of the thermometer is for the 5o I don't think mine ie reading correctly.

Would love to plc
