May be not quite what you're after but I built 'one' based on info from
this web site:

http://weather.overflow.net.au/station/stevenson.html

I've seen that site, thanks.

Bit difficult to lay thermometers flat in it, unfortunately...

I've been meaning to build one of these for some time but I'm still not
convinced that the relatively small volume won't still give rise to some
internal solar heating. How have you found it from this aspect? Dave

I have found it a significant improvement on the shield that came with my
weather station, but to be honest this is second best, summer high
temperatures are up to a degree too high. If I had the time, money and
skill I would make a proper (wooden) one

Paul,unless you could borrow Stephen Burts father in law I strongly
recommend saving your pennies and buy a shop made screen !,
Some 30 years ago I made one from one of those selfconstruct (destruct)
kits,and whilst that was not too onerous,it took a bleedin' year to paint !
..
144 louvers, 3/4 coats, all to be hand held, on laid against something,
I've still got the paint marks on the patio to prove it .......

It's not that difficult to build a Stevenson screen. You need
reasonable woodworking skills

Ah...

and a fair amount of time. The raw
materials will set you back around £200 though, and there's the stand
on top of that, so the newer plastic screens are not as expensive as
they seem (and of course they'll need no maintenance).

I guess I'll have to stick to my mini-screen for now - even though it
over-reads significantly in sunny summer weather (which isn't much of an
issue this year...)

Based on around 4 years observations, the average difference in maxima
ranges from only about 0.3C in mid-winter, to 2.7C in mid-summer.

I've noticed no seasonal variation in minima readings, though.

I also made one from a kit around 30 years ago, and only had to
replace it last year. I completed it an a week or so. It did involve
using half the house to lay out the pieces though.

Something to sing while you're building your Stevenson Screen:

Would the louvre doors that you can get in B&Q etc be suitable?
Assuming you can still get them, that is; it's a while since I've been
in a DIY shed.

I had a look in B&Q this week, but didn't see them.

Small pine louvre doors:

£8.48. Full height ones (to cut up) are £23-odd.

So £70 + top, stand, fittings and paint... so that's what, £100 in all
and a great deal of time and patience? Hmmm... who's going to try it
first?

.... not sure if this would give you any ideas, but when I made my own
screen (and another for my sister) a few years back, I used the vents
that are recommended for allowing air to gas installations etc.,
available from any DIY shop. You can get a broad idea of the
construction and use from this view:..

Although it wouldn't pass muster for 'official' observations, I was
pleasantly surprised when I had an overlap period with Beaufort Park
back in 1999-2003. The only thing to say is don't assume that plastic
= no painting. In my experience, white plastic turns increasingly
'off-white' with time, so I paint the panels along with the rest of
the screen (which is wood BTW).
