Hi Steve, grovelling apologies, I didn't mean that you would use one, but there are, I'm given to understand, people under 40 who use these computer thingies, and most of them wouldn't have a clue what we are talking about. I've seen people these days using horrendous 'one size fits all' things that rely entirely on toothed jaws to give any grip because its convenient!

(I have been known to use a brummagen screwdriver on occasion though (blush))

Personally I always found Stilsons a bit bumpy to sit on, a 1«" BSP spanner is just as effective and less uncomfortable (grin)
