Talk to me about windscreens, wipers and heaters
The bike engine has gone, and the MX5 engine is half in.
I've acquired a windscreen, that fits the Indy scuttle. However it's an ex Westfield one, so comes with cast brackets that don't
quite fit the Indy scuttle.
Thinking of buying the flat plate brackets instead. Anyway, any hints, or tips on the following would be appreciated.
What angle does the screen go at, or do you just rely on the bottom of the bracket being level?
Has anyone found an alternative to the landrover type wiper motor, tube and wiper boxes? Does the wiper motor fix to the scuttle or the chassis? Any
hints on locations for the wiper boxes? Most cars seem to have them equally spaced either side of the centre line but wondering if that means the
middle is double wiped, and the driver side is wiped less? Are they going 180 degrees?
Final question for now, is about demisting the screen. Will two vents be OK, or are more better?
Cheers

Classic vw beetle wiper motors are a good choice as they are a complete unit, easy to fit and worked with a similar size windscreen. That's what
I have to fit to my car, but after the IVA. As for the windscreen, it's location is often based in the hood and or sidescreen shape if you plan
to use those. As for the landy wiper system it's noisy, full of play and very crude though quite easy to adapt to different cars, plus the motor
can be located in the engine bay. But it's still clunky.

I had a screen on my first build, it was very windy, misted up in the rain and the wipers were worse than useless, my second and third just had a wind
deflector, less windy and any rain gets blown over the top....my 2p worth

Re demisting I suspect the issue isn't so much one or two vents just getting enough demist power. In my experience it's the bit directly
of front of the driver that needs demisting the most  . The screen is quite vertical so it does create a negative pressure behind it which can cause
really quite significant misting while driving which isn't a great thing.

I'd seen a classic beetle system, and thought it might be a suitable alternative. Do you have any photos of it mid installation?
I don't think I'll buy factory weather gear, there's a lad over the back of me who does custom work.

I dumped the heater in my 7 as it did nothing,
The wiper system was a modified 1970,s Mini unit tubes and wiper gearboxs, with the smallest blades and arms i could buy !
You need to alter the throw in the motor box, its easy!
The system worked enough for mot standards, but in reality the system was poor
Also, as said, the bufforting was awful,
What worked better was Rainex, inside and out, as that dispersed the rain, and stopped misting inside

As Conrod says.
I fitted one after it passed IVA.
Didn't keep it long as the buffeting was terrible.

Deflectors (elephant ears) either side of the screen reduce the buffeting loads.
Phoned the local ramblers club today, but the bloke who answered just
went on and on.

Deflectors make a huge difference - I discovered this by experimenting, after a passenger complained that she couldn't breath on the motorway,
while I was having no problem. The first experiment was for her to hold her arms in front of her as if holding a steering wheel ... that turned out to
be why I could breath fine!

That’s interesting, my wife always says she can’t breathe in my car when I don’t have a problem, I always put it down to me being used to breathing at
terminal velocity!

They do  One of the best things that I did.
No buffeting below around 80MPH

After that I fitted a rear screen, very comfy at any speed

Thanks all, Rainex is a good shout, used to use in on my visor.
And I'll definitely be fitting side screens or ears, and possibly a rear screen too.
40inches, where did you get the external rubber trim from? I'm a bit confused by all the different profiles!

It is a H trim with the bottom leave cut off, bonded to the bottom and front of the frame.
The black ally screws are to keep the ends in place as it sets
H Trim from Woolies Link
I made some side doors, with these and the deflectors Motorway speeds are not a problem

Lockdown2 strikes!
I've bought a pair of book style screen brackets, but want to get the angle of the screen right.
Do you just put the bottom of the triangle on horizontal to the floor // chassis rail?

Hi,
I have a Luego Velocity. I am using a Westfield screen and cast brackets with integrated wing mirrors. I am also using the Westfield doors with elbow
bulge. The doors were a late addition after using the plastic deflectors. I had to make sure the deflectors were pushed a long way out or I still got
buffetted.
When I fitted the doors I adjusted the screen angle to fit better. I also have the Westfield fibreglass trim piece at the bottom of the windscreen and
wipers fitted. I am very happy with the fit and finish.
Why do it the easy way, when I can do things my way!

Couple of pics in my archive before changing angle and fitting wipers and doors. If I get a chance later I will try and post some updated pics

My experience: kept it simple with a mini heater box, two demister slots on top of the scuttle and mini wipers. Demister and heater worked a treat.
Wipers less so, but acceptable given the fact you could not drive fast in the rain anyway without the car trying to kill you all the time.

What hinges are those and how do you stop the screens flapping?

As others have said, if you fit a windscreen you need side screens. My car is very comfy at motorway speeds with both. Don't bother with aero
screens as they do nothing.
Mini wipers are easy, but for wipers to have any real purpose you need a roof because water gets on the inside of the screen. I'm in the process
of fitting a micro heater / demister. Hopefully will be powerful enough.

Hinges from Amazon and used a thin tiewrap around one of the hinges.
Do a search for 50mm lift off hinge on Amazon.

I go into some detail on my website about how I fitted my windscreen - LINKY
The biggest lesson I learned was that it would have been far easier to fit at the time I built the scuttle, rather than several years afterwards...
My screen now has 'elephant ears', made of polycarbonate sheet, cut and folded into shape and bolted to the windscreen brackets (I started
off by making patterns in stiff card to check size and shape). They are not adjustable, but fortunately my guess worked out OK. I could have adjusted
the bend in the metal tabs if it had turned out wrong.
They do help to reduce buffeting a huge amount. They are shown in this photo, although they're not very easy to see.
