with some retrofitting you can add the weldless TC port from brewhardware.com, i think you should have enough room no welding needed. I was thinking about ordering one just to toy with to make a hop doser also
Or if he has access to ss welders, brew hardware has solder and weld triclamp flanges.with some retrofitting you can add the weldless TC port from brewhardware.com, i think you should have enough room no welding needed. I was thinking about ordering one just to toy with to make a hop doser also

Don't want to pee on anyone's Wheaties, but the lack of a proper PRV should raise some serious red flags. Worst case scenario, the keg over-pressurizes. Remember, it's rated to 130 psi. From an engineering standpoint that means its 50% overload/fail point is around 190 psi. A regular pressure cooker has a safety release slightly above 1 bar/14.7 psi, so an unchecked over pressure to 190 psi would be much greater than an exploding pressure cooker (about 10 times greater, if not 100 times greater considering area rule).
Remember the Boston Marathon bombers? Yep, used a pressure cooker. So if its burst pressure was ~15 psi + 50% = ~22 psi, what do you suspect the blast field would be if a roughly 4x greater volume under 10x or 100x greater pressure decided to come unglued? Granted, this explanation doesn't take into account the explosive energy and the rapid chemical expansion going on inside the pressure cooker turned IED before it's breached, but this over-simplification should convince you nevertheless that Bubba, you don't even want to be in the next adjacent county to that 'bottle bomb' when it blows. High pressure fluids are not something to take casually.

....until the S-trap gets clogged with krausen....
I certainly know that I'm not the only person who's had one block from a vigorous fermentation, resulting in a krausen volcano when the lid popped off a bucket fermenter. That snap on lid on a plastic fermenter won't hold 2 ATM/29 psig without popping off, but at least nobody dies when it does (will).
To be fair, as long as the bubbler doesn't clog, the keg will vent. I'm not comfortable betting my health and well being on a $.50 piece of plastic. You may be. But the device the OP built is designed to seal the keg to achieve an oxygen free dry hop dump.
And as I noted, both his and yours lack a proper PRV. A PRV isn't there to release pressure. It's primary function is to prevent a catastrophic explosion.

I also ferment in a corny and have been looking for a way to dry hop without opening the lid and came across this tread. Did you end up getting a response or finding a solution? Thanks!I shot Jaybird an email, waiting to see what he says. I'm a little worried about the size of that bore for getting pellet hops in, let me know if it works.
Nah, I've just been opening the lid and purging...I also ferment in a corny and have been looking for a way to dry hop without opening the lid and came across this tread. Did you end up getting a response or finding a solution? Thanks!

What size is that? And why is it not quite there? Because the handle isn't wide enough?
I think I gotta rotate the position of the closing lever 180°. It could fold down toward the prv instead of the ferrule.It might be a little pricey, but what if you were to drill where the current PRV is, put the TC ferrule there and put in a new PRV on the opposite end?

Can you put an extension tube between the lid and the TC fitting, high enough to clear the bail?Lid doesn't close properly. Lever is sitting on the triclamp opening. Won't actually allow anything to connect to it currently.
How did you reverse the lever? Looks great!Alright, reversed the lever. We'll see if this works. I don't have a clamp currently to test it.

I feel like I want professionals in a wide open area with all safety precautions to do exactly this.

1 5/8" / 41mmHow big of a hole does that TC fitting require be drilled?
Thanks. I'll have to think about this for sure... total for parts might be as much as a kegmenter after all's said and done....1 5/8" / 41mm

Maybe? The added bulkhead was only $20. I already had the lid, and I consider the drill bit part of my tools budget. I spend too much there, too....Thanks. I'll have to think about this for sure... total for parts might be as much as a kegmenter after all's said and done....
Update: Success!! (?)
I started over with a second lid. Cut a new hole further from the PRV, flipped the bail, and tested with a clamp. Fits with plenty of clearance. All in all, it took less than an hour after work today to do. The obvious problem seems to be that the bail will only fit single handle kegs now.
