Corny thumper

[Corn Cracker]

I thought I had seen a thread a while back about making a thumper from a corny keg.
I was going to use 1 of mine for this and was wondering how to get the quick connect fittings out of it so I can make those holes bigger to use for the in and out.

Use a wrench/spanner and unscrew them.

[Corn Cracker]

They weren't screw in. I used the cut off wheel on the grinder and a uni-bit (cone bit) to open the holes up to 1 inch

Pics are always handy . If not to help you , but the next fella that comes along .

It's gonna take a little love to get looking good but, there is my thumper in the making.

[Yummyrum]

Thanks for the pics Corn Cracker .

Looks like the beginning of a fine Thumper .
Should be a good match for a 15 -18 us gal keg boiler .

What would be the better diameter for inlet and out, I was thinking of using 1inch pipe, or would ¾ be better or maybe a 1 inch inlet and ¾ out? Just getting opinions before I make it, I've got a couple of weeks before I use it.
It will be used with a 15g keg

I'm going to go with 1 inch in and out, it was available and I don't want to wonder if I should have used 1inch instead of ¾. I'm hoping to get out today and work on it. I did grab some 1½ pipe but, I think it's too big use on the corney.

I am 2nd guessing using the quick connect ports as my in and out, too late now but......

[Corn Cracker]

I was able to spend a few hours in the garage this afternoon and got the corney thumper ready for soldering the down pipe and out. I need to get 2 1 inch unions to finish.
I don't know how the pics got mixed up, sorry

Looks nice Corn Cracker.

My cornys use a rubber gasket to seal the main "lid".
How did you get around that?

[Corn Cracker]

There are silicone gaskets for them, I'll find it and post a link. I'm wondering about the pressure release valve, I'm sure it has a rubber o-ring. I'll check that tomorrow.

That's the first one that popped up

[Corn Cracker]

While looking at the prv in the lid, it occurred to me that that is the high part of the domed top of the corny, so I made that my exit spot. I had already made the holes on each side though so, I dropped a ¾ female adapter in there and brazed it, I'll get a ¾cap to block the inside.

I'm waiting on my 1 inch unions to get it all soldered up

[Corn Cracker]

I got my unions and got to work, I had a hard time with the brazing again but, I got it done. I will get pics up tonight when I get it all together and cleaned up.

I'm thinking about 3 inches off the bottom of the thumper for the end of the down pipe?

If you haven't got things together yet... I have mine as close to the bottom without touching.
My thinking is that the hot gasses coming over from the boiler will immediately start moving upwards. (heat rises)

Just my $.02

I lowered it to within an inch of the domed bottom

It's almost complete, I need to get some fruit of some sort ferminting so I can run it with whatever fruit I'm using in it. For my corn and bourbon I'm not sure that I'll need to use a thumper. Either way, I'll always have it ready to go
