[WH40K] How powerful is the Ork collective gestalt field?

I've seen it described from just nudging red cars to go faster to basically creating a blaster out of piece of wood and some nails with the power if imagination. So how much of an effect does it actually have?

It varies wildly. In some cases, Ork equipment is usable by others (albeit with a lot jamming and malfunctioning) - it only runs smoothly because of the WAAAGH's effect. In others, an Ork 'gun' can consist of a metal pipe with a belt of bullets fed in and a trigger assembly - no firing mechanism required, and the pipe may not remotely fit the bullets.

Where it gets confusing is that there's no apparent correlation between size of the WAAAGH involved and how powerful its effect is. Certainly warbosses will pull off crazier stuff the more renown and followers they get, but some quite small (by 40k standards) Ork groups still had quite an effect, while the largest weren't noted as pulling any more overtly spectacular displays of psychic manipulation. A larger WAAAGH may manifest itself in other ways - for instance, more 'advanced' Ork technology being 'invented', rather than 'basic' equipment working in increasingly absurd ways.
