How on earth does a sawstop saw work?

[Mugshot]

I suspect this is not precisely a DIY tool, but I wondered whether a wiser person than I might be able to explain how it works to me? @woodbutcher possibly? I've also heard @Andy in Germany is pretty good at stopping machines
No idea how this video slipped into the recommended videos on YouTube; it's far from an area I'm familiar with. But I was stunned by this amazing device that is a sawstop. The bloke in the vid takes a shot at explaining how it works, but left me no wiser. I suspect it's some form of fiendish quantum electrodynamic magic.

So if anyone can provide a more rational explanation, I'd be so grateful ... and will subsequently confer upon you the title 'Mage of the Highest Order.'

I can't answer your question, but I'd like to say that that video is porn, it's not as porn as Henry Cavill building a PC, but it's porn nonetheless.

Well that won't work for long, where's his earth strap.

The teeth flying off the blade due to the g force is amazing. But also dangerous.
i bet it isn’t a cheap system, how much for blades and the brake pads?

I once saw a colleague carrying a large prototype circuit board which had cost the company many thousands of pounds. It was not in an anti-static bag, he was walking across a carpeted floor***, and worst of all he was absent-mindedly running his fingers over the back of the board as if strumming a guitar! He was an experienced electronics engineer so he definitely should have known better!


*** There can be a big build-up of static electricity doing that. I have had a nasty jolt when touching a door handle at the end of a long carpeted corridor.

The blades on the dado stack slipped when braking & teeth collided on 2 of the blades, surprised that ever passed a safety test
Single blade saw setup would work fine.
I worked in joinery for many years, using a ring fence on a spindle moulder without the safety cage kept your buttocks clenched

Yep been there too but strangely nobody bats an eye at using an overhead router without guards despite that cutter doing 22,000 rpm.
