Wow..I've had better tolerances using a spoon to cut with.
That has to be one of the worst videos I've seen in a while. Does he even understand what he happens to be talking about?

He was just making sure that the weld would have full penetration

Whoops, I've not seen a demo go so bad since yesterday as it happens. I was in at a customer who wants to buy 6 AC/DC tigs, so it's a very decent order. I was a little concerned about the competition's machine as it's cheaper than my offering and I hear their demonstrator is slick. I needn't have worried, they dropped off the machine, handed over a manual and some torch consumables and left!
The customer then spent the next hour unsuccessfully trying to get an arc out the machine (it turns out the little toggle switch on the front to tell the machine whether or not the torch is gas or water cooled hadn't been set correctly before leaving the shop meaning the machine shut down immediately after attempting to strike an arc)
Needless to say, the client was not über impressed :/ and my demo (and I'll be first to admit I'm an average welder) was much better received.
First impressions and all that...
You always test your gear before showing it to anyone, and you make damn sure it does the job the customer asked about and that they understand how to use the equipment before you leave, or else you're likely to be left with egg on your face.

Saw an epic fail when a guy was demonstrating a fall arrest system, attached it to the overhead crane, climbed up some step ladders and jumped off, ended in a heap on the floor
we didn't buy any.

Almost as good as a welding video I saw a while back by some american guy who said whilst welding, something along the lines of not wanting to melt the metal together and weld it all the way through as it wasn't needed ?!?
He was making a trailer for his car.....I wouldn't want to drive behind him on the freeway !!

God that's horrifying. Shame, because in 2D with someone who can measure properly it looks like a useful circle cutter. Probably works alright on pipe too...as long as all your joints are at 90 degrees. Not sure how that works with building dune buggies though!

oh my dear god that is pathetic. I am crap with a plasma but could have got a better fit freehand.
the first cut was too big, the second was too tight, there are sharp edges, nothing fits.
may as well have used a coffee mug as a template and cut it with a butter knife

He has three problems:
1 - he hasn't rehearsed his performance prior to filming it and uploading it to Youtube. He could have done it better.
2 - His idea is flawed because the bit that's cut out isn't a projection of a circle over a cylinder, the geometry is wrong although it might work well enough for some people.
3 - He's pitching a potentially clever idea to people who fabricate things - we can all see what his trammel does and if his demo was good, he might have convinced his audience not to buy one but knock it up out of what they have to hand.
I feel sorry for him but I've seen plenty of well-meaning people put effort and money into a bad idea without realising the basic flaws.
