Welland 2019 Dyno test of Boadicea

[froudy70]

Theres more chance of getting hit by a bus than being hurt by a dyno test going wrong, should all buses be banned?

That's odd analogy. Think how many bus journeys there are in a year compared to how many dyno tests are being carried out (100's of thousands v a few tens?). I suspect the odds of an incident happening with a dyno are far greater.

There's nothing wrong with dyno testing, I don't think anyone has said there is. It's more about the way that some folk do it.

Be sensible and be safe.

Presumably the risk of this happening is more likely on a dyno due to the forces involved rather than thrashing or sawing? Having said that, using a belt will always carry some sort of risk so is a dyno really any more dangerous than other belt based activities?

My former neighbour, a very skilled railroad engine mechanic, used to call me" Captain Dangerous" for some of my adventures. However, after watching the video a few times I am rather left wondering whether, even I, would have continued the adventure past the time when the belt seemed to be quite violently shaking just before the incident.
Much as I enjoy seeing engines working hard I would suggest that public running on dynamometers should be done to a maximum of 80 % of what had been done previously privately, to avoid, as far as possible, any further incidents of this nature.
What people do in their own property is of course their own business, I have, and continue to, push limits, ( In my case nowadays of the capabilities of 2" and below models) privately. However, what is done in public and what happens in public view could adversely affect the whole hobby.

I agree, when the belt started whipping wildly was the time to shut down.

Especially given the belt had already come off once and fallen to the ground. A spectator had warned them what cold happen if they continued being so stupid, but he was ignored and this was the consequence. They are lucky the belt didn't hit anyone and that the bits of seat didn't strike a spectator.

Here is a video from the flywheel side of the engine.

Is it me or is the dynamometer moving towards the engine

I think the trend by some these days is to work an engine as hard as possible as if to show some mastery of the footplate... rather like the boy racers who drive everywhere as fast as possible and think applying pressure with the right foot makes them a superior driver.

What are the risks of a dyno test?

Is it more dangerous than any other steam engine activity?
