There is _no_ UK law against dado sets. There is a law (part of PUWER
98) that requires a rapid stop. As this is awkward to achieve with a
heavy dado set (you'd need to fit electric braking, which is
expensive), the cheapest fix for new retail machines is to shorten the
arbor.

Andy, I'm a bit confused by this comment. The Freud dado set sold by
Machine Mart (p. 296) specifically states "NOT to be used on any machine
with electric braking".
