TC fitting in place of standard barrel bung
I am about to fill my 15 gal barrel with my annual brett imperial stout. I was looking for a way to make the barrel more user friendly and oxygen free transfers. So far I'm going to be adding a sample/drain port for emptying the barrel as well as a ball lock fitting. I could PROBABLY just make a small drill hole into one of the staves and screw the ball lock setup into the wood. The better option would be to somehow get a TC fitting where the bung hole is located. I know there's a picture in Wild Brews with Vinnie smashing cherries into a barrel using a TC funnel setup. I just don't know how they got the TC in the bung. They may have just used a 1.5" or 2" plain ferule that they shoved into the bung but they may also have threaded some sort of fitting into the barrel.

Re: TC fitting in place of standard barrel bung
I'd be pretty interested in seeing that picture if you find it. I'm having a hard time envisioning it.

I would make your drain port separate from your sample port. I don't know how smart it would be to leave a ball lock sitting attached to the barrel. For sampling its easy to pull out a nail and put it back in.

I'm not sure I understand what you are saying about the bung hole. you want to attach a spigot like thing to the bung hole?

Re: TC fitting in place of standard barrel bung
The ball lock fitting is only for gas purposes. As the barrel is drained it can be back filled/push with CO2.

If you have the book Wild Brews the image I speak of is on Page 230. If you do not have the book I will go through the effort to scan and upload the image. I assume you have the book though.

It's hard to describe what I want to do with words I think. As you've done with the tapered barrel tap on your site, I want to add a drain spigot type of fitting. Then in order to prevent oxygen and aid in draining speed (not that it's a huge concern) I want to be able to push with low pressure CO2 and have a plan to add a ball lock gas disconnect. My guess is I could either add the threaded fitting the disconnect threads onto directly to the wood near the bung, or best would be using TC. I could add a TC ferule to the bung and drill/tap that for use with the ball lock fitting. This would allow for some cool flexibility with the barrel as a fill/empty it with repeated use. Let me draw something on mspaint and upload it for you with a link to explain myself.

Since a picture is worth 1,000 words. Here's my concept visualized. This way I could do things like ferment two 10 or so gallon batches in a corny ket and fill the barrel with CO2 then use a spunding valve built to attach to a ball lock fitting to slowly release low pressure CO2 preventing oxidation from the transfer. I'll likely be waxing some of the barrel too like you did on your site to prevent too much oxygen transfer. I figure I can do half the barrel or so and have a good ratio.

As a matter of fact I do have the book and its right next to me ;) I took a cell phone pic and uploaded it for anyone else reading this: http://i.imgur.com/NGRvO.jpg

From your description and awesome MS Paint skills, I have a better idea of what you are looking to do. What about eliminating the bottom drain spigot and putting in a pipe in the barrel with the top being at the bung hole with a TC fitting. Then as you push CO2 into the ball lock hole, it would push beer up that pipe.

Regarding waxing, Its not 100% impermeable, so I don't think you can wax too much surface. If I were you, I'd wax the whole thing except the heads.

Re: TC fitting in place of standard barrel bung
I suppose I could certainly do that. Maybe I can put two small TC fittings in the top of the barrel. One to handle the ball lock and one to handle the liquid side of things. The ball lock fitting will essentially be permanent and the liquid would be a end cap replaced with a bung and a racking cane that would be a tight enough fit for pressure but also allow me to move the cane up and down based on sediment.

See this is why I post this stuff. Thanks for the email Nate, that made things a little easier for me. I tend to over think stuff and try to throw too much commercial type thought into some of my home projects.

I think I will forgo the drain port and fill the barrel tomorrow maybe. I just need to pick up a bung to do that. I will likely wax the whole barrel too.

Speaking of waxing. I was looking up food grade epoxy to use in place of wax. I don't know if that'd be too rigid though and thought it might crack. I figured an expoxy would be better than wax at being impermeable to oxygen.

Re: TC fitting in place of standard barrel bung
put up some pics of the final barrel. I'd like to see what you rig up.

I don't have any experience with epoxy. The paraffin wax is nice because it basically soaks into the wood grain.

No problem. I went through a similar over-engineered thought process when setting up my barrels. The end result was a good compromise between cost and function I think.

Re: TC fitting in place of standard barrel bung
I've got a bunch of 15 gal barrels I haven't started using yet but what I was planning on doing was to take an appropriately sized bung and make two holes in it. One gets a stainless racking cane for beer out and the other just a short stainless piece for gas in.

Re: TC fitting in place of standard barrel bung
Well I have some stuff that would allow me to place a sample/drain fitting into the barrel if I so choose to go that route. I just need to more accurately measure the bung hole to see if that GW Kent fitting would work or not. I think it would but I think my bung is larger than 30mm at the top but it is a tapered hole. I may postpone filling for a week or two.

Re: TC fitting in place of standard barrel bung
I was able to put a drain port in the bottom of a barrel by drilling a 5/16th whole and screwing a 1/2 inch hex nipple into the barrel then put a valve and barb on it. It is currently holding beer and hasn't leaked at all.

what GW Kent fitting are you thinking of putting in the bung hole?

This is what I do with mine. Even with the 60G barrels.

Re: TC fitting in place of standard barrel bung
For what it is worth I do not think they have a tc fitting on the barrel. Rather they have a tc funnel set up on a piece of 1.5" or 2" SS pipe that is put through the bung while they smash fruit through it.
