Default Small model boiler explosion video

Dunno if this has been posted here before, but warrants viewing. Couple of folks heating a small model boiler (soft-soldered ??) with a blowtorch ( WTF were they thinking ??) , messing with the safety valve (or lack thereof) and disastrous results. Don't think anybody was hurt, but it's a reminder that even small model boilers pack an explosive punch. Go to YouTube (click the video image) and read the comments too.

Thanks for posting it Mike.

If safety isn't built into the boiler there
is no time to react if it fails.

What's the old addige

"A little knowledge is a dangerous thing"

I learnt in school, as we were building boilers in Engineering Class, about the catastrophic possibilities if they went wrong, blimey they think health and safety is a new thing ........... believe me our old engineering teacher could have written all the H&S Manuals, but he just incorporated it all into each lesson and it just became second nature, and that's more than 40 years ago.


Then again there was the woodwork teacher .............. his response to anything he felt was "not correct" was to launch a chisel at you .............. well close anyway .......... I feel he never quite embraced the whole H&S etiquette ......... then again he was Welsh

................. sorry Mike, I got carried away ....... ............ thanks for your post, excellent video to remind us all we need to be especially careful should we embark upon boiler production, glad it appears no one was hurt mind.

As model engineers we are trying to duplicate the big engines.
We certainly do not want a scaled down version of something

Yeah, I saw that video a few weeks ago. Listen to the commentary, they'd just done something to the "Safety Valve of Death", as they called it.

The last bit; "I need to open the tap fairly soon, because the pressure's now-" Bang.

Reminds me of those famous last words, something to the effect of : "Hey, hold my beer while I'll try this ....."

Ya can't fix stupid, so Here's your sign....

I was raised around a steam engine in the Rice country, S. Louisiana, we would run it for several months without a shut down, it was fun to play in as a kid but when I was 13 ran the 11 to 7 shift, the old timer that taught me said the same thing if you should let it run low on water let it die, he brought some old pictures of what looked like, when things went wrong, ours had brick around the boiler, that would have been something, it was installed in 1895, we stopped using it in 1972 and was working fine till the day we let it cool down, I can still hear the hissing and the smell of steam and the oil drips in my mind, I will post some pics of what still remains, it has been several years since I have been back, it was driven with one endless rope and DC power plant, life was simple, thanks for sharing bring back your information brings back good times, Lathe Nut
