So, if possible, have a good look round for some old gates, take the
time to clean them up, and they'll last a lot longer than the ones on
sale at B+Q/Wickes.

Cheers for that, they're only to keep the local scrotes^H^Hkids from
using the driveway as a goal, and we're planning on moving within a
couple of years, so they wouldn't need to be particularly heavy or
long-lasting :-}

Looking at the price of steel on the site I mentioned, if I had more
time (and could weld) i'd be tempted to knock my own up !

It's a real eye opener when you see mid-range gates going for £400 and
the bits to make it less than £40 - sure, labour is the biggest cost,
but even that must be minimal given that the site does pre-punched
steel so all you need to do is a weld in each corner, and literally
drop the vertical rods into place !
