Hi,

this sander has started to mis-behave.

Instead of running smoothly (if a sander can be said to run smoothly) the
speed is variable and it sounds generally rough.

I have taken it apart and there seems to be no obvious visible problem, and
the brushes still seem to be of a reasonable length.

The speed variation gives the impression of 'misfiring' - it speeds up,
misses a bit, speeds up again.

It does this on all speed settings.

Anyone had/solved this problem?

These days I guess having B&D tools serviced is not cost effective - even
years ago they used to prefer to trade them in against new at the service
centres.

Quite probably a break in the flex, close to the appliance inlet.
Quite often my drill's will do this.
It could be worn\dirty commutator\brushes, I had a cheap one that did
that, just turned out to be dust clogging up the insides.
