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 ca=
using the screens to move out. It=92s the same thing that allows airplanes =
to fly and sailboats to sail into the wind. The 100 doesn=92t have a channe=
l 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 sid=
e 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 t=
o increased pressure within the car, especially at speed.  Mounting and fit=
ting the curtains perfectly so that they notch in behind the windshield sta=
ntions just enough to resist this force is not easy and I came up an easy s=
olution:  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 stanti=
on using a small piece of angle in such a way that they are in their "attra=
ction" mode when the door is closed.  The magnets are more than powerful en=
ough 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.

Norman,

I usually buy my own felt, a fairly thin and dense one, and cut my own glas=
s and make sure it fits rather tight, then you have to =93pinch=94 the glas=
s in the channel at the top and bottom by tapping the divider against the g=
lass where it ends.

Subject: [Healeys] BN7 Sidescreens - Screen Fitting Instructions



Went for a drive the other day and as it was rather windy I fitted my new s=
ide screens for the first time and was impressed with the wind and noise pr=
otection they gave. Part of the drive took me onto a highway and when I inc=
reased 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 origi=
nal side screen assemblies I noticed the following:

1. The siding screen is in the inner channel which has a felt U-section =96=
 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 f=
elt blocks the drainage holes, the screen does not sit deep in the the chan=
nel, and the original side screens do not have this felt?



I have spent countless hours surfing the net, the archives, looking at part=
s books, and Gary Andersons restoration guidelines and can=92t find how the=
 screens are fitted inside the frame so I would be really appreciative of h=
elp and guidance.



Thank you
