Thanks for all the suggestions,that 2" PCL air operated grinder from machine mart looks really neat and compact.
It might be just what I m looking for.Â
Neil, the Dremel unit is cool i ll take a look the next time I m at a tool shop.
I ll be mainly using it for cutting in tight spaces, its mainly maintenance/repair work I do so a compact unit would  make the awkward jobs a bit easier.
