Your SVA questions answered...
Hi all. Back again after a short absence.
Long and short of it; I'm in the middle of a two-day MOT testers course. One of my fellow students is an SVA examiner from the Jupiter Road, Norwich
test centre. He's there getting MOT authorisation as another string to his bow.
Well, does anyone have any questions that you'd like me to put to him? We had a long discussion about projections and noise tests, the merits of
fitting windscreens and so on after the test etc...
I'll be in and out of here until 11:30 or thereabouts, so get your questions in tonight and I'll ask him tomorrow. He's a friendly guy (name of Les
should you be a Norwich local) and he's very forthcoming with answers to all my daft questions. 
Oh by the way, picked up my chassis, wishbones, ally tank and fibreglass parts from Luego at the weekend.  I'm on the way!!!
The quality of the bits and pieces is excellent, and the guys are friendly but very busy.
Grant, you're a star!
Come on then, start thinkin'!!

OK - I got one...
I want to step off my side panels like this Dax Rush to give a nice engine bay bent, but mainly cos it looks cool. But would the edge of this panel
fail an SVA on projections? Mine will have an exhaust either side too if that makes a difference.
Cheers
Liam

Damn!!! I thought i was going to be the only one doing that!!! I'm going to make those door things aswell, may even build it into the chassis rather
than them being removable!!

Hi Liam.
Spent lunchtime asking Mr SVA your question, and a load more of my own.
As long as the 100mm SVA test sphere cannot contact a sharp edge on the step-off, or pass into the vent, there shouldn't be a problem. If it can
contact any 'sharp' edges, they needs to have a 2.5mm radius. Depending on the gauge of your metal work, a simple return fold should take care of
it. He couldn't think of any other reason for failure in that regard.
Hope that helps.
I spoke to him about exposed frontal projections, and the double gaitor method is the preferred one. I asked him about noise limits, and he mentioned
the builder deciding the revs at which max power is achieved. As long as you're sensible with your 'half revs' statement, they'll accept what you
say, and you should easily achieve your noise test pass.
They're also fully aware that we all fit screens and bias valves, stick-on plates and steering wheels with holes in the spokes once we get home. One
Seven presenter even had his screen on the passenger seat when he turned up. It's what they test on the day.
Les invited me to get in contact when I'm close to completion and he'd arrange for me to watch a few tests to see what goes on. Nice guy. 
Oh, and i passed my MOT exam. 100% score too!
As a side note, the arguement about no lights whatsoever is valid. A mention will be made on the MOT paperwork, but you will get a pass on a vehicle
with no lights fitted. Just don't collect your car from the testing station after dark!

I must admit i got loads more info by going to see theconrodkid take his car through SVA,if you know someone who is testing its well worth tagging
along.
Although best to ask 1st,i'm hoping to go to at least one more test before i go through it myself.
Glad to hear the double gaiter idea is looked on as being OK,i'm going to have a go with convoluted tube over the track rod end and lock nuts.

What's the 'double gaitor method'? Just wondering, as I'm currently working in that area.

passed your MOT exam!!
well done mate, does that mean that you are now able to stick great big screwdrivers into cills and charge £400 to weld a plate over the hole you
made?

Its where the gaitor on steering rack ends and we used to cover the T/Rod end and nut with pipe lagging.
Evidently this is not suitable now so another gaitor seems to do the trick,like i said earlier i'll have a go with some split convoluted tube.

I'm probably being stupid but I can't quite see how you would fix the other gaitor neatly - or indeed in anyway that makes it better than a piece of
pipe lagging. In fact a piece of pipe lagging would offer much more protection I would have thought.
Do they seriously think that although we might remove pipe lagging we would baulk at removing some tatty bodged on gator?
Anyone got a picture? (of a double steering gaitor arangement!!)
Cheers
Phil

DOUBLE STEERING GAITOR
It was posted on this site by sonebody after their 1st SVA test,since they do not or are not accepting the pipe lagging effort that we would all
use.
The examiner said that the extra gaitor would be acceptable,i too think it would look stupid but its all about passing the test.
When i get hold of a digi camera i'll post what the convoluted tube looks like on the car,IMO it will look better than another gaitor.

I believe you can use as many lights as you want for main beam, as long as they all extinguish (sorry about the spelling) when dipped beam is
selected.

I think the time limit on these questions has expired since sparky has now finished the course.
And well done to sparky for passing the exam.

I noticed at the Exeter show that many manufacturers were using brake slave cylinder dust covers over the lock nut on the track rod ends, looked
really neat.
They were also using steering rack gaiters over the fwd upper wishbone member, looked really shoddy!
