Anyhow, there are numerous issues here, not the least being that it is
tough to mount a thick rotor so it still lines up correctly. It may be
possible to machine a part to adapt a motorcycle caliper and I have had
parts machined for my MTB. Requires time though. As I said, first I am
going to see if the 8" rotors are good enough which they very well may
be. 6" in back was clearly not adequate.

Good Lord! A disc is just about the simplest thing that you could
design - two circles one inside the other - and almost the simplest
thing to manufacturer. Even in the wilds of California you should be
able to find either a "home machinist" or a commercial shop to make
them to your specifications.


Take a look at a modern MTB, how much available clearance there is and
then think again about your statement.

I do take a look. Just about every time I visit my LBS, and I see no
problems with installing a disc, or a bracket for the caliper for that
matter.


Check again, this time with glasses and measuring calipers. Between
rotor and fork there is about 1/20th of an inch on my MTB. A 3mm rotor
would barely squeeze in, a 4mm rotor would not. It would scrape.

Something wrong with your measuring. 1/20th of an inch is 0.050" which
is 1.27mm so your 3, 4mm disks won't fit.... or your measuring device
is off a little.


Fire up your calculator again. My MTB came with 2.2mm rotors. How much
wider is a 3mm rotor?


I don't care what calculator you use. You said that the clearance was
1/20th of an inch, i.e., 1.27mm and that you install a 3 mm rotor.

I assume that in California you have some sort of magic measuring
stick that lets you insert a 3mm rotor in a hole that is less then
half the size.


sigh

2.2mm rotor which was in there before plus 1.27mm clearance is ...
drumroll ... 3.47mm. Meaning ... trumpet blare ... a 3mm rotor will
fit. A 4mm rotor will not fit. That was easy.

Brewing is a pretty exact science. Mess up one step and $50 plus 4h of
work go down the drain, literally .

Fauja Singh, born 1 April 1911) is a British Sikh centenarian marathon
runner of Punjabi Indian descent. On 16 October 2011, Singh became
the first 100-year-old to finish a marathon, completing the Toronto
Waterfront Marathon in 8:11:06.[

Ed Whitlock, at 85, set his latest distance-running record, completing
the Toronto Waterfront Marathon in 3 hours 56 minutes 34 seconds and
becoming the oldest person to run 26.2 miles in under four hours.

Harriette Thompson, 92, became the oldest woman to complete a marathon
on Sunday when she finished the San Diego Rock 'n' Roll Marathon in
7:24:36. She surpassed the record set by Gladys Burrill, who ran
9:53:16 at the 2010 Honolulu Marathon, 19 days after her 92nd
birthday, when she was 74 days younger than Thompson is now.

Yup it is a sure thing that running is bad for you.


My great grandpa lived to almost 103 and regularly smoked big stinking
stogies. The kind where I started to cough from just being in the same
room. So according to your "logic" cigar smoking is perfectly ok for the
health?

No body said anything about smoking stinky cigars. You said that the
doctor told someone that running would destroy the hip joints and I
gave you examples of people that ran for 50 years or more.


I gave you an example of a guy who smoked stogies all his life and
lived. I have a lot more. You gave me a few examples of people whose hip
survived intense running. Same thing.


Now, I can take the time and trouble to look up a few more if you
wish. There is even an "old Folks" Olympics (National Senior
Olympics). The event was first held in 1987 and the most recent event
(2007) had over 10,000 competitors, the oldest of whom was over 100
years old.

How about that? 10,000 people that were running and leaping about the
stadium compared with your one example with a bad hip.


How about millions of heavy smokers who did not die from lung cancer?
