Do the log books have a standard format?[quote author=RhysN
link=topic=208.msg1357#msg1357 date=1567590852]
Further to Bill's comments about checking previous shortcomings.
Putting on my motorsport hat, every car there has a logbook in
which things are noted. If something is a bit "not quite as it
should be" like an advisory on an MOT then the car can run, this
time, but needs to be rectified for the next. More major things
must be fixed and rechecked before running.
Now I know this may sound a bit OTT, but when (not if) we get to
20+ CKs running perhaps a logbook should be already in place.
Nice record for the car too in the future.

Pretty much the same in the countries I know about and would be
easy to formulate if there is a collective will.

Re: Lessons Learned - Safety - Bugatti improved steering column

I've improved the end fixing of the steering column by:
extending the column so there's lots more thread beyond the
Nyloc nut
Putting a cotter pin through the threaded end.
I did drill and tap the end of the column, but thought a bolt
there was just as likely to shake loose so wouldn't add any real
safety.

THese are the issues I've had on my various outings at Stretton:
Drive sprocket bolt came loose.
Axle keys loose and sliding
One rear hub bolt came loose
All the above were spotted and corrected during paddock checks,
however, the following were not spotted!
Steering wheel temporary retaining pin vibrated out resulting in
loss of steering
Steering column rode up as grub screws came loose, resulting in
loss of steering (again) I was fortunate in both instances to be
able to come to a controlled stop.

The only problem with the Morgan was the camber "increasing" on
the nearside which Rhys rightly red flagged me for. On
examination it proved to be a combination of not being able to
pull the wheels up tight (I thought because the washers were
binding on the outer races), and me going quicker. Having just
unloaded it I found the washers were actually bearing against
the hub, not the bearing outer race, so the play was increasing
as the hub wore, solution make spacers to replace the washers, a
length of 3mm wall tube is on it's way.
The log book seems like a good idea, my thoughts are just a
sheet on excel to fit an A5 binder, with columns: date; problem
(fault possibly); action taken. I'll knock one up for my use
shortly, and share it here.
As for the grub screws not holding on the axle, one solution is
to position the bearing, lock up one screw, and spot drill the
axle about 3mm deep, replace the grub screw with a dog point
one, then repeat for the other one.

Great link Geoff. I've only read a couple of sections and I've
already learned helpful stuff.

On the subject of safety, I was buying Xanny a cash helmet
yesterday and the gentleman taking my money raised a good point.
They don't recommend mounting GoPro's on the sides or tops of
crash helmets, in an accident they can puncture the helmet
making things
very much worse. Their recommendation is if you have to mount a
go pro on your helmet do it on the jaw line at the front as that
is the strongest bit.

Mounting Go Pros on helmets is forbidden in all authorised
motorsport.

I agree bill, we mounted ours there. we also mounted in a
relatively weak way so it is more likely to break off than catch
on anything, further reducing risk of injury. It must be taken
with a pinch of salt though therefor I only helmet cam a minimal
amount.
