Tin openers

Jagged, or in your post "jagged edge", implies to me an element of undulation of a cut surface.

I associate a jagged edge of a 20 litre drum to be akin to that left behind using one of those old fashioned tin openers with a blade my grandmother might have use which you worked around the top of a tin.

Yet the clean cut from a current tin opener looks benign, but equally dangerous. I know of one person attending A&E and requiring stitches from a non-ragged edge of a tin.

Perhaps you can educate me so I can better understand "ragged" pertaining to 20 litre drums.

Perhaps but I doubt it. Take a lesson on netiquette instead:

Depends what is inside it of course!

There used to be a very big kind of ratchet shears thing I saw being used to do this, but it still needed in some places the sides deburring. I should have paid more attention.

Because its funny.. that is why. Have you no sense of humour? Brian

I wonder if his link mentions humour, or lack of?

If you need to do it on an industrial scale then a type F machine from here..

What's funny an angle grinder. It might have been somewhat witty the first time it was used as a joke on here but the new millennium is heading for it s 2nd decade. To some of us it is still funny but to the normal people on h ere (very few of us it seems) it isn't "still funny".

Granted, there are one or two jokes that can stand being told repeatedly, i n the case of such, it is more in the presentation than the punch-line. But whilst I have your attention: What text to speech programme(s) do you use and do you happen to know if it runs on Linux?

Suck it and see if I switch it on for you.

What, like contrails?

I saw one of these at a car boot this morning but he wanted too much for something I couldn't see was working:

If i was thinking of making wood burners, patio-heaters or BBQ stoves, I' probably get one. But I have a Dremmel somewhere. so I thought I'd try that first.

So a small die-grinder? Not so different from an angle-grinder after all ...

Unless you count the OP.

Going off some of the posts, Brian, I think it was a can of worms?
