Cutting top off a Sanke keg using angle grinder

[lincoln]

thinking back on it i was shock about how easy it was to grind a sharp edge on the side of the opening (top or bottom) only a light touch should be needed. i normal use #42 to clean up stock/welds and that was way to aggressive. a #80 and a light touch work well. good luck

Here's mine:

After cleaning up with a half round file, I dare say they are perfectly round and smooth.

hrm maybe I need to look into a 1/2 round file. I have a file, but its a itty bitty tiny round one that didn't seem to do any thing when I tried it.

that will mostly put 1/2 round divots on the underside, just light touch with the grinder.

When cleaning up with a half round, you slide it laterally as you file up or down so that you aren't cutting in one spot throughout the stroke.

well my flapper disk worked like a charm I have a smooth edge it was a "light" touch like I thought I'd have to do, but it did work out perfect.

I already cut 1 keg with this method a few months ago for my boil kettle - worked really well. Stuck on a weldless bulkhead+ball valve+QD from morebeer and a sightglass+thermometer combo from brewhardware -- really happy with it all.

Picked up two more kegs this morning to serve as my HLT and mash tun and ordered the false bottom, bulkheads, etc, just need to pick up a couple more cutting disks. Movin' on up...

O ya, if I had some flap disks or other lighter abrasives I'd do that over a hand file. The hand file was just what I had and I like having that level of control over the tool. I like to think Roy Underhill would be proud.

I used a twisted metal wire wheel (this one) to deburr and round the edge after cutting it. Like butta.

Just wear some thick gloves, goggles and a welding apron if you use that thing, they tend to throw off some pieces of wire at 12,000RPM every so often.

 

[Flomaster]

yeah I have bad memories of the wire wheels i dislike them.

I thought it was going to be a light touch, but I had to give it a bit more umph then I anticipated, but in the end it worked out well.

Won't that embed iron into the SS, resulting in a patina of rust later

Flap disk is best. An old-fashioned deburring tool works fine on the smaller drilled holes.

I wonder if they make a 12" step bit...

 

[KRYLOK]

thats no too hard, i got 3 kegs but the beer inside is at lest 6 years old. I don't know if i even want to try lol
