Simple wooden screen
-
Dear All,
I saw this simple wooden screen while visiting Kew Gardens. It had been placed in front of a large window and provided a very nice diffuse light. A number of water colours of plants and flowers were also hung from the screen.
Sometimes, simple is best.

Bob

Thanks for sharing.

I like doing screens like that only I us a simple square cut notch in the uprights.
http://woodsshop.com/bbrbqrgb.htmI wonder how they cut those notches with that little shoulder left square at the top? Do any of you woodworkers have a guess? A bevel cut with the radial arm would get the top angle but how to cut that remaining square part?

Dear Joe,
I might have remembered the design wrongly, and so it is quite possible that the shoulder is not there. It is over a week ago that I saw the screen. You could, of course, water jet cut the recesses, but that might not be economical.

hey Bob, have you ever done (or had done) any wood cutting with a water jet? If so I have some questions about cutting 1.5" thick, clear western red cedar.

Dear Joe,
I have no experience of water jet cutting wood, but I have cut 1" aluminium plate and so I think that 1.5" of wood should not present a problem. There are some systems that will cut through 2 to 3"of steel. I have used laser cutting to cut 10 mm MDF, but the edges char (not surprisingly). For that application it didn't matter, and the price was right.
I have mostly used the technique for cutting shapes out of 1.5 mm stainless steel sheet. I used AutoCAD to array the shapes within a 1 m by 2 m rectangular boundary (sheet stock size), and then emailed the file to the the water-jet company to download into their control computer. It worked very well, it was very accurate and very economical on materials. If you look at Fig 2 on http://www.atm.ox.ac.uk/main/facilities/2point2_metre_facility/cool_6.html you will see some close-off panels on the floor. Those panels were shaped using water jet cutting, as was the bespoke cable tray.
