[Healeys] BN7 Sidescreens - Screen Fitting Instructions

Actually the effect you are seeing is the Bernoulli effect. The air outside is moving faster than the air inside, which lowers the pressure outside causing the screens to move out. It’s the same thing that allows airplanes to fly and sailboats to sail into the wind. The 100 doesn’t have a channel to hold the front of the screen so I made a couple tabs of strap ally and mounted them under the top hold down screws. Worked fine until my Moss side curtains fell apart. Got them in waiting until I get a new set...

I believe that side curtains on roadsters have a tendency to blow out due to increased pressure within the car, especially at speed.  Mounting and fitting the curtains perfectly so that they notch in behind the windshield stantions just enough to resist this force is not easy and I came up an easy solution:  I mounted a 1" square neodymium magnet to the front inside upper corner of each curtain and a similar magnet to the rear face of each stantion using a small piece of angle in such a way that they are in their "attraction" mode when the door is closed.  The magnets are more than powerful enough to overcome the pressure from within the car and yet they release when the door is opened.

I forget now my source but the magnets can be ordered with holes predrilled in their center and they are chrome-plated.

I usually buy my own felt, a fairly thin and dense one, and cut my own glass and make sure it fits rather tight, then you have to “pinch” the glass in the channel at the top and bottom by tapping the divider against the glass where it ends.

Went for a drive the other day and as it was rather windy I fitted my new side screens for the first time and was impressed with the wind and noise protection they gave. Part of the drive took me onto a highway and when I increased the speed to 100 km/h the fixed screen on the drivers door blew out (thankfully there were no other cars around me)

Taking a closer look at the side screen frame and comparing it to the original side screen assemblies I noticed the following:

1. The siding screen is in the inner channel which has a felt U-section – same as the originals

2. The outer channel, for the fixed screen is filled all-around with a high density felt which is just below the channel lip.  Is this right, as the felt blocks the drainage holes, the screen does not sit deep in the the channel, and the original side screens do not have this felt?

I have spent countless hours surfing the net, the archives, looking at parts books, and Gary Andersons restoration guidelines and can’t find how the screens are fitted inside the frame so I would be really appreciative of help and guidance.

Thank you
