Putting up bookshelves - 5.5 metres wide, by 2.1 metres high. Decided
to go down the slots and brackets route - by the way, don't buy at B&Q
- each 1.4m slotted rail was £10, whereas a pack of £10 was only about
£15 or something at Screwfix.

Anyhoot, the problem is the brackets. The smallest Screwfix offered
was 220mm, but I really only need about 150mm. So I'm looking for a
way of cutting the ends off these suckers. Trouble is, there are
about 80 or 90 of them so a hacksaw is NOT the way I'd like to go.

They're made of steel, quite rigid. Does anyone have any
suggestions? I guess I could try to find a metalwork shop somewhere
but they're not exactly thick on the ground in Cheltenham (as far as I
know). Is there a power tool that I could hire to do it?

Many thanks

Edward
