What is the difference between the different sort of sanders?

I am looking at
http://www.bosch-professional.com/gb...-101283-ocs-c/

In particular, what is the difference between an orbital sander, and a
random orbital sander? (Other than that one is rectangular, and the
other circular.)

I understand what a belt sander and a detail sander are.

I have two applications in mind:
- Touching up the worn oak floor in the living room
- Sanding down the stair case I am currently stripping (preparatory to
repainting).

Yes. That helps a lot.

Martin,

I have a 5" Random Orbital if you want to give one a try. Basically the
same as the METABO SXE450.

I've got the Metabo SXE450, and I'd also recommend it. Capable of being a kitten or a tiger, and has happily put up with being pushed hard. 150mm punched discs are readily available, and the polishing bonnet useful too.

Random orbital sanders are brilliant. Put a 40 grit disc on & they
remove stock almost like a belt sander, put a 120 grade disc on & they
give a fine finish.

What I am keen to try is one of the so called dual action sanders...
they look like a RO sander, but have both a powered orbit and a
(selectable) powered rotation mode rather than the rotation just coming
about as a side effect of the orbit. They are apparently popular in car
body shops etc (where they also make good polishers).

Yep, I've used one before but for car polishing. Very effective it was too.

I'd second that. I bought one to re-finish oak worktops and wouldn't
bother trying anything else on a large flat surface. Mine's a cheapo
(B&Q PP) but if I had known ho good the format would be, I woul have got
a decent one.

Detail, of course, is another matter.....

Not to sure about the comment 'first produced in 1982' ... think they
have been about longer than that

I believe you're correct - my Dad died in 1977, and I have his
random-orbit sander.

A random orbit one will do pretty well everything an orbital will do - but
so much better.
