Just a question on cutting a keg, which way do most do it?
Cut from the side and leave the handles as per the wiki, or cut from the top with a small lip around the outside?

I am leaning towards cutting from the side as I will be doing BIAB until I get the hang of it and this will mean no catching the bag on lifting.

What are others thoughts?

Cheers

One good thing about leaving a lip Robbo is being able to put a lid from a pot or frying pan on top.

I cut a circle in the top of the keg to end up with something like this (not mine)

If I could do it over, I might consider turning the keg upside down and cutting this circle in what was the bottom of the keg, so you have a ready made bottom-draining fitting (the old coupling from what was the top of the keg.)

I'm not a fan of cutting the whole top off the keg minus handles, it looks like it weakens the keg itself, you'd get a bit of flex in there from removing the rim around the top? Not a huge deal but since you're only going to do it the once.. It's also handy having somewhere to rest stuff on top of the keg - I find myself dumping the mash paddle/stirrer/odds and ends around the top there on a brewday.

I'd say the 'majority' definitely cut as per the picture above, doesn't make it best though and FWIW I don't BIAB.

As per hsb supplied photo.

Definitely go the fitted lid from a saucepan. Helps bring up to boil. just make sure to remove the lid when it gets there, or earlier.

If going gas fired you cant bottom drain, but if electric, you could possibly use the coupling point to install an element if you can find one that fits.

Also agree the handles add (or retain) some funtionality on brewday, not just for lifting either. I also store my paddles and transfer tubes around the top rim on brewday.

Depressurize keg before going it with a grinder too....

Cut it as per the picture above with the hole size ready to take saucepan lid sourced from Woolworths (lid only available)

Cut lid with Grinder and wooden cutting jig.

See ebay video on how to make jig. perfect cut every time.

I dissagree. The walls of them are thick enough that they do not flex if you cut the whole top off. Why do you need a lid on a keggle? I have tried both styles myself: just cut a circle or cut the whole top off. I think taking the whole top off makes them heaps easier to clean. I cut down the ring from the top and welded handles to the side of the keggle, this worked very well. Another has no handles but because it is on a frame, it has no issues.

I agree with cutting the arse out of it and using the spear coupling to fabricate a bottom draining outlet, if it were a mash tun. Bottom draining keggle might be ok if you had an electric element in it but if gas fired, well that could complicate things.

With a decent angle grinder I think it's just as easy to do it by hand without the jig.
Will have to visit the local Safeway to see if they have lids to fit.

I cut the top out as per hsb's photo then just welded some tabs around the edge piece that was cut out. The cut-out bit then becomes the lid, the tabs stop it falling back in the hole. It has a 1mm gap around the edge of the lid but it's only used to help get the boil going a bit quicker then it's removed.

I have watched the how to on cutting the tops out of the kegs . To me it seems to be a lot of dicking around to create a jig when all I did was use the guard on the grinder as a guide simple really .

 

[JaseH]

I did mine free hand with no jig - its not needed. Mark out a circle to suit a 32cm glass lid, use a thin cutting disc on a 100mm angle grinder. Make a shallow groove using light pressure on the first run following the line, make sure to go slightly inside the line rather than outside(easy to enlarge the hole later, but you cant shrink it!), the disc will track in the groove from then on, do a few more passes around until you break through and your set. If the hole is too small for your lid, use a grinding disc to enlarge it a bit at a time until your lid fits.

I've done 4 kegs this way and they came up perfect! I also clean up the edges with a flap disc as the final step, but you could use a file in a pinch.

Hey Robbo.
I would cut from the side and leave the handles if you are doing BIAB. The Bag does catch if you don't have the hole big enough. I had tried using a keggle with just the top cut out and wort goes every where as the bag squeezes through the hole. Ended up giving the keggle the flick and acquired one of Ross' 70L pots.
Cheers,
Hammo.

Cheers to all for the replies, I think I will go the hole in the top as I think I will eventually end up with a 3v brewery.
If it doesnt work * can always cut from the sides.

Cheers

I'm having trouble figuring out how to de-pressurise a keg so I can start at it with an angle grinder & drill

This is a picture of the valve..



all of the videos I've watched have different types & methods but none that look like the above image. Has anyone that's done it before got any advice?

 

[iralosavic]

Just push the valve in deep enough to open it. A screwdriver would work fine

Yep.

Just keep your face away from it as you depress the valve (it will take a fair bit of effort) otherwise it's golden shower time.... :lol:

 

[breakbeer]

Just had another go at it, thought I mustn't have been pressing hard enough.

Propped it up against a wall, on it's side & put all my weight behind the screwdriver. Didn't budge at all

Drill a hole in the section you are cutting out.

 

[homebrewkid]

just push down on the rubber the gas will escape when it has no gas left you need to undo the whole top by gripping it with something i used a 3 jaw oil filter remover and it was easy to undo with that
it wont come out when you undo it you need to grab the centre metal bit [inside the rubber seal] lift it and turn it to disengage the spur then it all comes apart
google how to open ''A'' type keg if you run into problems
or you could just depressurise it and drill a small hole in the lid to be sure since you are going to cut it off anyway

 

[Maheel]

use a socket that fits the rubber area and can slide down the steel bit and a Tbar socket bar

put socket bar on throw a towel over the top and depress the rubber with the tbar

once no pressure

you do have to drop the middle stem bit in, use a big pair of plyers / multigrips to grab the stem and lift twist till it "drops"

then i used a thin punch to get it turning by taping it around via the little hole then just turn it by hand "righty tighty lefty loosen"

once you get it all out cut the little lock tab off the spear if it has one...
