Thanks for all the thoughts re direction. Some interesting thoughts and observations there.

As for the Brooklands image Rhys posted, it shows just how huge it was, or put another way it makes me realise how much of it we have lost :-(

I feel certain this is a bit of a silly question, but it is the early hours...
does not distance between the sprockets affect the amount of slack that should be used?
Or is the 15mm what seems to work and ignore the distance?

Tech Forum / Stretton are you clockwise or anti?
« on: 20 December 2019, 12:13:45 pm »
Good morning, whilst at our last event at Stretton I spoke to a couple of people and am now interested in everyone else's opinion.

Which way round do people prefer to drive at Stretton, and why? The last time we were there we drove it anti clockwise

Personally I prefer clockwise, for me it flows better, the flick through the first corner with tyres squeeking, the drop down to the bottom hairpin and keeping as much momentum as possible through it, and then keeping the foot in until the tight 's' bends despite getting loose through the corners. Oh joy :-)

So what's others opinions? Has the Tribble got it wrong?

Tech Forum / Re: Wheels and spokes
« on: 20 December 2019, 11:22:49 am »
Ok, so it seems to me that there a huge amount of variables, so far...

quality of wheel, owner maintenance or not, thickness of spokes, whether they are supported both sides of the hub, weight of CK/driver, new or second hand, only driven on the flat or across the landscape.

Could I also add to the list size and gripyness of tyres, the more the grip the greater the loading.

So realistically to many variables to draw acreat conclusions other than, for us to inspect our wheels regularly.

Impressive work with the numbers you two.

A couple of thoughts about the numbers...

Top speed 33 MPH, that's got to be higher, we know CK's have hit 50 in USA and I would personally add 10 percent for safety on top of that.
Time spent braking, like Stefan 5 seconds seems way too long, from my own driving experience it's more like 1 - 1.5 seconds.
Also should you not be using a terminal velocity of zero, since worse case scenario we would be 'red flag' situation, immediate stop on track? 

As Rhys and Stef have both eluded to, not so good braking but reliable/constant is safe, but brakes that start excellent but then degrade not good. I agree with this.

Also just a thought, with your driving position Dave, your knees are heavily bent, this physically push's the end of your foot downwards, are you riding the brakes without knowing it, even if only slightly? I know when we are sitting in the cars stationary it's easy to notice these things, but when we are being bounced around on track different story.
I think we have been looking for the one answer when maybe two factors are involved. Increase both pressure and disc size/mass. Pressure will give you braking force, mass will give you reserve of energy absorption...think that all makes sense???
