stevenson screen
Does anybody know where to buy a cheap stevenson screen? Second hand, new or whatever. Cheap would be less then €150 !
Otherwise: does there exist a construction instruction for such screen?

Re: stevenson screen
Thnx. Nice video but I don't have a workshop with the tools nor the craftmanship like that
I think I'll go for a buy somewhere...

Re: stevenson screen
How about 3 small plantation shutters?
I think I could fabricate one like that with minimal tools.
Other easy to work with product we have here is PVC building trims in various sections.
Roughly what dimensions were you thinking?

Re: stevenson screen
I don’t think there’s such a thing as a cheap Stevenson’s screen. Pretty complicated to make if you stick to the official design. The one shown in that video was quite small.
But with a VP2 I’m curious why the OP wants one. For housing a separate thermometer to check the VP2’s is correct?

Re: stevenson screen
Roughly 1 x .5 x .5 m
And yes I think self built is the only option.
For some additional AQ experimentation, electrical equipment and computers.RayProudfoot wrote: ↑Fri 20 Aug 2021 10:26 pm But with a VP2 I’m curious why the OP wants one. For housing a separate thermometer to check the VP2’s is correct?
And of course some additional sensors and a reference thermometer.
My VP2 has nothing to do with it.
BTW: what is the OP?

Re: stevenson screen
Thinking aloud ...
Most basic construction ...
4 x 1.8m x 75mm (square) fence posts (approx. £35)
4 x louvre doors h435mm x w894mm (approx £80)
A few other bits of wood for braces / mountings and a piece of wood for the sloping roof.
Paint, hinges / fixings etc.
Put the posts in the ground (slightly higher on the North side.)
Screw 3 of the louvre doors E, S, W.
A couple of braces for the real hinged door (North)
Paint inside matt black, outside gloss white.
Create whatever mountings you require.
Pop the roof on, and Bobs your cross dressing auntie.
As the roof slopes South, you could even cover it with a solar panel (to charge your phone )

Re: stevenson screen
@beteljuice: @Phil23: Thanks! Very useful. I am getting there. I may even try and contact that British guy although the advertisement is more than a year old but it lead me to another eBay advertisement: Single Louvre Door is the key
And from there it is only construction material and a standard. I don't think I will pass the € 150

Re: stevenson screen
OK, I will post my progress here now that I got my main construction wood from a neighbour: six extreme hardwood poles (I cannot saw this by hand) as a stand, which won't rot in Dutch boggy soil in my lifetime. The height of the screen (bottom) will be between 1 and 1.5 meter above ground (the top will be 50 cm above that). I will glue the panels with Polyurethane glue. That is quite poisonous so I have to do it outside - I don't have the ventilation required - and it needs 4 hours in glue clamps. As it is now winter with hardly a dry day and below 5 degree C that has to wait a bit longer unfortunately. But it has started!

Re: stevenson screen
Hi Hans
This looks like a really good project, are you going to paint the louvres? I am sure that it will make a difference to your data recording but by how much? I have seen from your webcam that you have a much more open aspect than me so a big screen may help in getting a true measure of temperature.
I have my Davis unit set on a pole about a meter above a pitched roof so winter temps are fine but summer temps may be a bit elevated but, looking at other stations around me, not by much.
I look forward to seeing the completed screen in due course.

Re: stevenson screen
Hi Andy,
The webcam is north and is not my ground, can't place the screen there. It will be placed east and 50 m south of what you see (out of reach of the camera). A reference thermometer will be surely placed inside just as some sensors. And whatever I can lay my hands on
Thermometers on a roof always have a bias. That may be not so much where you live but in a real urban area that can be several degrees. Especially pwsFWI has a bias when calculated from urban data. That is one of the issues with personal weather stations calibration is difficult.
I'll post the photos of this slowly progressing project
Regards,
Yes, will paint it white outside (of course) and black inside.AndyKF650 wrote: ↑Fri 11 Mar 2022 4:56 pm This looks like a really good project, are you going to paint the louvres?
