Yes weather can effect it a lot but that is not an excuse for poor service it simply wouldnt wash with our customers nor should it with you!

What speeds did they quote you?

The box in the house is a ViaSat Linkstar S2A.

To be fair to BT when they installed the system, they didn't set my expectations high for response speeds, quoting around 1MB.

The problem is that it's so inconsistent, there can be times I get 1.5MB, and others that I get 56k!

I could look at the other Satellite providers, but aside from the huge set-up costs for the initial install, they all put a 'cap' on data useage, I think the most I can get is about 6GB per month.

That is nowhere near enough for the amount I use.

The current service I get via BT is unlimited.

lol so off topic i love it.
but what would you rather have

unlimted **** use.
or capped good use?

i understand you have paid for the setup as it is now etc.

hes right. look at the pictures of the old wheel. 2 bolts at the top. now its 1 bolt at the top.
unless hes put a different hub on it?

Just re-fitted the polycarbonate windscreen;

This was fitted when I first bought the car, but it was so scratched that visibility was terrible, especially in sunshine.

I decided to let my friend at a bodyshop have a go at it with a machine polisher and some special perspex polish, and the results are pretty good. Better than spending £230 on a new screen anyway!

The plastic screen saves 5kg compared with a glass one, so well worth having. You can see in the final photo the alloy brace which is required to stop the perspex bending inwards at speed!

My current car trailer is getting very long in the tooth, so I have just invested in this little baby Brian James Micro-Max. They're designed for towing Smart cars behind motorhomes, but luckily it fits the Nova absolutely perfectly (although only just!);

Nice!

Where did you get your mirror Colin?

Thanks.

The mirror was in the car when I bought it. I've never seen another one like it, and there is no manufacturers name on it anywhere.

do you actually use the mirror? its not like they let other cars up the course at the same time is it???

^Its a nova, its for seeing what parts you are losing on the way up.

This just gets better and better everytime i see it.

Makes mental note to swipe it next time we meet then...lol

It's useful when backing it into my workshop, off the trailer, and into parking spaces in busy paddocks.......there's sod all visibility behind you with the head restraints on the seat.

People who've followed this thread will recall that I got a quote for building a rear beam in titanium, which was going to be made to accept some lighweight KAD Mini brakes and hubs that I bought.

That plan was abandoned due to the absurd cost of making a bespoke rear beam.

So I am now looking at modifying a Nova rear axle to accept the Mini hubs.

A friend of mine has got a book which details every possible combination oif wheel bearing, so he's taken away the measurements of the Nova stub axle, and the Mini rear hub, and hopefully he can find something to match the two together.

Failing that it will be a question of machining out the hub assembly to accept whatever he can find to suit (note to self - check a Nova rear wheel bearing, just in case it miraculously fits straight in!).

I've been doing a bit of mocking up on a spare axle just to see how it will all go together;

http://i285.photobucket.com/albums/l...cort/030-5.jpg

If the right bearings can be found it should be pretty straightforward, obviously the main thing will be modifying the existing caliper bracket, or making one from scratch if that proves easier.

A Nova rear drum weighs 6.5 kg with the shoes, cylinders etc. The alloy Mini rear hub, with caliper, pads, mounting bracket is 2.5kg.

So a very useful saving of 8kg in total.

lol, theyre just a bit sweet arent they..

the stub is basically a 22mm straight shaft to suit a mini hub. maybe the old lathe could wizz the nova ones down a bit

Great idea, thanks.

Machining the stub axle has got to be a better plan than machining the hub. Plus I've already got a set of Mini wheel bearings. The magic of the Internet allowing you to bounce ideas off the World.........

I will go and take some measurements off the Nova stub axle, and hopefully it's bigger than 22mm.

the only issue you might have is getting the track correct. that mini one looks a lot narrower than the nova one...

can you do anything with the top half of the bulk head etc, i know you have things bolted to it...

drill holes?

and is it allowed in your cat

No, no lightening holes are allowed in the bulkhead, and I can't remove any of it either.

darn it lol ill go back to the drawing board :D

The tapered part on the Nova stub axle starts off at 22.4mm, and goes up to 29mm at the back section, so it could have been made to be slimmed down to 22mm right the way along its length!

The section that the bearing sits on for a Nova is 40mm long, so I need to check that against a Mini to see how far back it needs to be machined to.

Definitely looks promising though.

Nice setup. It makes that that beam look like something from Steptoes yard.

Please powdercoat or make it look sexy when its being done for real.

Don't worry, this beam is purely a test bed, I will bolt it all to the one that's already on the car once I'm happy with everything.

when you consider the diameter of the metal & the mileage you will be doing, i don't think it would need hardening afterwards. i can't wait to see it again.. is there a list of hills you will be at this season?

Cant you make a beam from CDS?

I was considering this myself at one stage and still am If my other plan is flawed lol.

Like Austin did on his saloon??

Did he , got a link Scott?

I sent several messages to Austin requesting weights/details of the beam he made, but he never got back to me.

Yes, I could get one made, but I'm not sure that there is anything to be gained from it.

Once the drums and ARB are stripped off a standard Nova rear axle, there's not really a lot of weight to it. I reckon fabricating one from scratch might be more trouble than it's worth.

But if anyone thinks differently I'd be interested to hear other views.

Ive neve done it, but I really cant see it being too difficult to be fair.

For this season I've only got one more event lined up........Gurston Down on 12th September.

But I do plan to do at least one other event somewhere this year, so I can get another signature on my licence and get it upgraded to 'National A'.

As yet I haven't decided which event to do.

I'm planning on a fairly major Winter rebuild/improvement programme, and then a wider range of events next year (funds permitting).

Is IRS not an option Colin -can post a few pictures if it helps

What was your thinking behind wanting to fabricate one? Purely to save weight?

Yeh for weight, do you think it would not be lighter? Also using RJ's on the car mounting points, setting the shocks in more vertical plane, can make it round a corsa whiteline ARB for example, that actually works?

Just a better design, I havent really looked into it too much, more just an idea between me and my mate down the yard.

No, it's not an option withiin the 'Production' regulations that I'm bound by.

The same style of suspension that it left the factory with has to be retained.

So you can't replace a MacPherson strut with a wishbone for example. You are allowed to alter the pick-up points a little (maximum 20mm IIRC), but that's it.

damn... i'm going to the silverstone 1000 km that weekend

I think I said it before, but having a titanium beam would probably end up as heavy if not heavier getting it as stiff as the steel beam you are replacing.

Didnt you have a shell with IRS before? I'm sure you know whats involved with that setup? Maybe a Honda style setup could be grafted in at a lesser cost?

I would recommend getting the stub axles hardened IMO. Do you do the turning work yourself?

There is a company in wisbech who will make any wheel bearing you need any size :) Brt bearing iirc

They wont make ones for the f28 though lol

My neighbour has a lathe and is a good engineer, so I'm hoping I can persuade him to assist.

But if that fails, a friend in Bournemouth is a toolmaker and I'm sure he'll work for beer. He'd be able to do the hardening as well.

Shouldnt take too long to turn two stub axles. Ideally they want to be turned down to around 22.25mm, case hardened and then turned to size with a diamond tipped tool. Thats how i would do them
